    Full Text Available Ensuing from isokinetic measurements, the conventional Hcon/Qcon ratio of muscle balance is used as an index for comparing proper relations between the values of strength of knee flexors and extensor muscle. Its abnormal values might indicate pathology of the musculotendinous complex. The aim of the study was to present the possibility of using this ratio as one of the objective identifiers enabling the assessment of knee injury risk in sports. All participants (n=48 were divided into 3 groups: group A (n=16, healthy competitors, group B (n=16, athletes with minor injuries, group C (n=16, competitors with serious injuries, depending on the degree of knee injury. All subjects performed an isokinetic test for knee extensors and flexors at angular velocities of 60°/s and 120°/s. Average peak torque (APT value of knee flexors and extensors, and the value of Hcon/Qcon ratio was analyzed. Both values were calculated in relation to body mass (Nm/kg. Bilateral comparison of isokinetic test parameters confirmed the decrease of quadriceps muscle strength values for the injured extremity in groups B and C. Statistically significant difference was noted for Hcon/Qcon ratio between group A and C, as well as B and C. Hence, the value of conventional Hcon/Qcon ratio can be used for the prevention of sports related injuries.

    Articular cartilage defects in the knee of young or active individuals remain a problem in orthopaedic practice. These defects have limited ability to heal and may progress to osteoarthritis. The prevalence of knee osteoarthritis among athletes is higher than in the non-athletic population. The clinical symptoms of osteoarthritis are joint pain, limitation of range of motion and joint stiffness. The diagnosis of osteoarthritis is confirmed by the symptoms and the radiological findings (narrowing joint space, osteophyte formation and subchondral sclerosis). There is no strong correlation between symptoms and radiographic findings. The aetiology of knee osteoarthritis is multifactorial. Excessive musculoskeletal loading (at work or in sports), high body mass index, previous knee injury, female gender and muscle weakness are well-known risk factors. The high-level athlete with a major knee injury has a high incidence of knee osteoarthritis. Cartilage injuries are frequently observed in young and middle-aged active athletes. Often this injury precedes osteoarthritis. Reducing risk factors can decrease the prevalence of knee osteoarthritis. The prevention of knee injury, especially anterior cruciate ligament and meniscus injury in sports, is important to avoid progression of knee osteoarthritis.

    Team handball is associated with a high risk of severe knee injury that needs to be reduced, particularly at the youth level. The purpose of this study was to show how an injury-prevention programme effectively reduces severe knee injury in adolescent team handball players. Of 23 adolescent handball teams of both sexes, 13 were randomly allocated into the intervention group (168 players) and 10 into the control group (111 players). Players of the intervention group regularly participated in an injury-prevention programme for one season. Handball exposure and sustained injuries were documented for both groups on a monthly basis. The primary outcome parameter of the injury-prevention programme was the incidence of severe knee injury. Of the 279 included players, 68 (24%) sustained 82 injuries yielding an overall incidence of 1.85 injuries per 1000 h handball exposure (intervention group: 50 injuries/incidence: 1.90/1000 h; control group: 32 injuries/incidence: 1.78/1000 h). Knee injury was the second most frequent injury in adolescent team handball. The primary outcome parameter, severe knee injury occurred significantly more often in the control group [mean age (SD) 15.1 (1.0), injury incidence 0.33/1000 h] than in the intervention group [mean age (SD) 14.9 (0.9), injury incidence 0.04/1000 h]. The odds ratio was 0.11 (95% CI 0.01-0.90), p = 0.019. Other injuries to the lower extremities showed no significant difference between the two groups. Frequent neuromuscular exercises prevent severe knee injury in adolescent team handball players and should thus be included in the practical routine as well as in the education of team coaches.

    Injury prevention training has been shown to be effective in reducing the incidence of noncontact anterior cruciate ligament (ACL) injury; however, the underlying reason for the success of these training programs is unclear. To investigate whether an ACL injury prevention program that has been shown to reduce the incidence of ACL injury alters sagittal plane hip and knee biomechanics during a drop-landing task. Descriptive laboratory study. Thirty female club soccer players (age range, 11-17 years) with no history of knee injury participated in this study. Kinematics and ground-reaction forces were collected while each participant performed a drop-landing task prior to and immediately after participation in a 12-week ACL injury prevention training program. After ACL injury prevention training, participants demonstrated decreased knee extensor moments ( P = .03), increased energy absorption at the hip ( P = .04), decreased knee-to-hip extensor moment ratios ( P = .05), and decreased knee-to-hip energy absorption ratios ( P = .03). Participation in an ACL injury prevention training program decreased reliance on the knee extensor muscles and improved use of the hip extensor muscles, which may explain the protective effect of this type of training program on ACL injury. Based on these findings, clinicians can better understand how ACL injury prevention training, such as the Prevent Injury and Enhance Performance (PEP) Program, may change movement behavior at both the hip and knee. Furthermore, the study findings may support the implementation of the PEP Program, or a similar program, for clinicians aiming to improve use of the hip in an effort to reduce knee loading and consequent injuries.

    Anterior Cruciate Ligament (ACL) injury is frequently encountered in sports. To analyze the effects of ACL injury prevention programs on injury rates in female athletes between different sports. A comprehensive literature search was performed in September 2012 using Pubmed Central, Science Direct, CINAHL, PEDro, Cochrane Library, SCOPUS, SPORTDiscus. The key words used were: 'anterior cruciate ligament', 'ACL', 'knee joint', 'knee injuries', 'female', 'athletes', 'neuromuscular', 'training', 'prevention'. The inclusion criteria applied were: (1) ACL injury prevention training programs for female athletes; (2) Athlete-exposure data reporting; (3) Effect of training on ACL incidence rates for female athletes. 13 studies met the inclusion criteria. Three training programs in soccer and one in handball led to reduced ACL injury incidence. In basketball no effective training intervention was found. In season training was more effective than preseason in ACL injury prevention. A combination of strength training, plyometrics, balance training, technique monitoring with feedback, produced the most favorable results. Comparing the main components of ACL injury prevention programs for female athletes, some sports-dependent training specificity issues may need addressing in future studies, related primarily to the individual biomechanics of each sport but also their most effective method of delivery.

    Full Text Available According to many statistics over 55% of all sports-related injuries are incurred in the knee joint (active sportsmen and recreationists. The statistics definitely differ, depending on type of sport and specific movements habitually performed in a particular sport. Therefore, in addition to acute knee injuries overuse syndromes are common in the knee area also due to specificities of patellofemoral joint just because specific diseases like „jumper's knee“ and „runner's knee“ are related to certain sport activities. Generally speaking, these syndromes occur due to poor orientation of the knee extensor mechanism, i.e. friction of iliotibial band and patellofemoral chondromalacia. It is believed that about 45% of all overuse syndromes in the knee area occur as a result of running.

    Volleyball is a source of direct injuries and chronic overloads of the joints, which indirectly results in traumas and permanent dysfunctions. This applies particularly to: knee joints, ankle joints, shoulder joints and small joints of the hand, as well as the joints of the lower spine regions. Each league team should employ a physiotherapist who would be responsible for the implementation of an injury prevention program as well as for choosing the right training loads. The purpose of this study is to analyze the frequency and the type of knee joint injuries occurring in people practicing Volleyball at competitive level as well as to propose the usage of elements of modern physiotherapy in order to prevent these injuries. The tests were performed over a group of 19 volleyball players from Poznan. In order to propose measures that would prevent injuries, the authors carried out a review of modern physiotherapy methods and suggested the implementation of certain therapeutic techniques for the region of the knee joint. RESULT ANALYSIS AND DISCUSSION: As much as 79% of the subjects reported having chronic pain and knee joint injuries in the past. All of them, due to their conditions, declared having used various forms of physiotherapy treatment. It seems that in a professional sports club not only the presence of a massage therapist but first of all a qualified physiotherapist is indispensable.

    Knee injuries are common in adolescent female football. Self-reported previous knee injury and low Knee injury and Osteoarthritis Outcome Score (KOOS) are proposed to predict future knee injuries, but evidence regarding this in adolescent female football is scarce. The aim of this study was to investigate self-reported previous knee injury and low KOOS subscale score as risk factors for future knee injuries in adolescent female football. A sample of 326 adolescent female football players, aged 15-18, without knee injury at baseline, were included. Data on self-reported previous knee injury and KOOS questionnaires were collected at baseline. Time-loss knee injuries and football exposures were reported weekly by answers to standardized text-message questions, followed by injury telephone interviews.

    Although most ACL injury prevention programmes encourage greater hip and knee flexion during landing, it remains unknown how this technique influences tibiofemoral joint forces. We examined whether a landing strategy utilising greater hip and knee flexion decreases tibiofemoral anterior shear and compression. Twelve healthy women (25.9 ± 3.5 years) performed a drop-jump task before and after a training session (10-15 min) that emphasised greater hip and knee flexion. Peak tibiofemoral anterior shear and compressive forces were calculated using an electromyography (EMG)-driven knee model that incorporated joint kinematics, EMG and participant-specific muscle volumes and patella tendon orientation measured using magnetic resonance imaging (MRI). Participants demonstrated a decrease in peak anterior tibial shear forces (11.1 ± 3.3 vs. 9.6 ± 2.7 N · kg -1 ; P = 0.008) and peak tibiofemoral compressive forces (68.4 ± 7.6 vs. 62.0 ± 5.5 N · kg -1 ; P = 0.015) post-training. The decreased peak anterior tibial shear was accompanied by a decrease in the quadriceps anterior shear force, while the decreased peak compressive force was accompanied by decreased ground reaction force and hamstring forces. Our data provide justification for injury prevention programmes that encourage greater hip and knee flexion during landing to reduce tibiofemoral joint loading.

    Overuse injuries are frequent in the knee joint. The reason for this is that the knee joint is engaged in all sports activities. Furthermore, the joint area has numerous attachment points for muscles and tendons and numerous bursae. Another reason is that the specific joint between the patella and femur (patellofemoral joint) constitutes a part of the knee joint. Speaking in general terms, all overuse injuries in the knee joint can be divided in four groups according to the aspect: anterior aspect--patellofemoral pain syndrome, patellar tendinitis (jumper's knee), Osgood-Schlatter disease, Sinding Larson Johanson disease, stress fracture of the patella, fat pad syndrome; medial aspect--plica syndrome, semimembranosus tendinitis, pes anserinus tendinitis (bursitis), breaststroker's knee, medial retinaculitis; lateral aspect--Iliotibial band friction syndrome (runner's knee), Popliteal Tendinitis, Bicipital tendinitis; posterior aspect--fabellitis, medial gastrocnemius strain. There are numerous possible reasons for pain caused by overuse injuries around the knee joint, but two are the most frequent: patellar tendinitis (jumper's knee) and Iliotibial band friction syndrome (runner's knee). This paper gives a brief overview of overuse injuries of the knee joint including their definition, anatomy, aetiology, clinical symptoms and signs, and non-operative and surgical treatment.

  20. Biomechanical risk factors and mechanisms of knee injury in golfers.

    2013-09-01

    Knee injuries in golf comprise approximately 8% of all injuries, and are considered to result from overuse, technical faults or a combination of those factors. This review examines factors involved in injury, including the structure of the knee joint, kinematics and kinetics of the golf swing, forces sustained by knee joint structures and the potential for joint injury as well as injury prevention strategies. The golf swing generates forces and torques which tend to cause internal or external rotation of the tibia on the femur, and these are resisted by the knee ligaments and menisci. Research has shown that both maximum muscle forces and the forces sustained during a golf swing are less than that required to cause damage to the ligaments. However, the complex motion of the golf swing, involving both substantial forces and ranges of rotational movement, demands good technique if the player is to avoid injuring their knee joint. Most knee injury in golf is likely related to joint laxity, previous injuries or arthritis, and such damage may be exacerbated by problems in technique or overuse. In addition to appropriate coaching, strategies to remedy discomfort include specific exercise programmes, external bracing, orthotics and equipment choices.

    Twisting injuries occur as a result of differential motion of different tissue types in injuries with some rotational force. These injuries are well described in brain injuries but, to our knowledge, have not been described in the musculoskeletal literature. We correlated the clinical examination and MR findings of 20 patients with twisting injuries of the soft tissues around the knee. Design and patients: We prospectively followed the clinical courses of 20 patients with knee injuries who had clinical histories and MR findings to suggest twisting injuries of the subcutaneous tissues. Patients with associated internal derangement of the knee (i.e., meniscal tears, ligamentous or bone injuries) were excluded from this study. MR findings to suggest twisting injuries included linear areas of abnormal dark signal on T1-weighted sequences and abnormal bright signal on T2-weighted or short tau inversion recovery (STIR) sequences and/or signal to suggest hemorrhage within the subcutaneous tissues. These MR criteria were adapted from those established for indirect musculotendinous junction injuries. Results: All 20 patients presented with considerable pain that suggested internal derangement on physical examination by the referring orthopedic surgeons. All presented with injuries associated with rotational force. The patients were placed on a course of protected weight-bearing of the affected extremity for 4 weeks. All patients had pain relief by clinical examination after this period of protected weight-bearing. Twisting injuries of the soft tissues can result in considerable pain that can be confused with internal derangement of the knee on physical examination. Soft tissue twisting injuries need to be recognized on MR examinations as they may be the cause of the patient's pain despite no MR evidence of internal derangement of the knee. The demonstration of soft tissue twisting injuries in a patient with severe knee pain but no documented internal derangement on MR

    2011-01-01

    Cartilage injuries are frequently recognized as a source of significant morbidity and pain in patients with previous knee injuries. The majority of patients who undergo routine knee arthroscopy have evidence of a chondral defect. These injuries represent a continuum of pathology from small, asymptomatic lesions to large, disabling defects affecting a major portion of one or more compartments within the knee joint. In comparison to patients with osteoarthritis, individuals with isolated chondral surface damage are often younger, significantly more active, and usually less willing to accept limitations in activities that require higher impact. At the present time, a variety of surgical procedures exist, each with their unique indications. This heterogeneity of treatment options frequently leads to uncertainty regarding which techniques, if any, are most appropriate for patients. The purpose of this review is to describe the workup and discuss the management techniques for cartilage injuries within the adult knee. PMID:26069581

    Full Text Available This prospective cohort study aims to assess the overall incidence of acute and overuse basketball injuries and identifies risk factors associated with ankle sprains and knee overuse injuries. In total, 164 senior players (23.7 years ± 7.0 of all levels of play, and including both men and women, participated voluntarily during one season. A total of 139 acute and 87 overuse injuries were reported, resulting in an overall injury incidence of 9.8 (8.5 to 11.1 per 1,000 hours. The incidence of acute injuries was 6.0/1,000 hours. Ankle sprains (n = 34 accounted for most acute injuries, and 52.9% of all players with ankle sprains reported a previous ankle sprain. Relative Risks (RR and Odds Ratio (OR with their 95% Confidence Intervals (CI were calculated to determine significant differences. Landing on an opponent's foot was the major inciting event, significantly more so than non contact mechanisms (RR=2.1 [95% CI: 1.0-4.2]. Acute knee injuries resulted in the highest playing absence (7 weeks 2 days ± 9 weeks 1 day. Overuse injury incidence was 3.8/1,000 hours. The knee (1.5/1,000 hours was the most common site. Forward players sustained less knee overuse injuries than players of all other playing positions, and significantly less than center players (OR=0.5 [95% CI: 0.2-0.9]. This study showed that ankle sprains and overuse knee injuries are the most common injuries in basketball, both accounting for 14.8%. Injury prevention programmes however should not concentrate on those injuries only, but might one to consider that acute knee injuries, in spite of the fact that they occur less frequently, also merit further research.

    Intraoperative positioning injuries during shoulder- and knee arthroscopy are rare complications and affect mainly nerves and soft tissue. Although the majority of these complications are reversible, in some cases serious negative consequences for the patient persist. This article describes the frequency of several positioning injuries including their prevention and the appropriate treatment. The legal responsibilities are illustrated as well as the importance of an intense preoperative investigation of preexisting diseases and possible risk factors. Furthermore, a review of possible thermal injuries of the patient during arthroscopy caused by e.g. electrosurgical instruments or the cold light source, is given as well as prevention strategies.

    Full Text Available Background: the guarantee of sporting success lies in the appropriate functioning of the musculoskeletal system, given that its vulnerability hinders the performance of each athlete. Being timely is critical to provide safe care to the affections of knee; late diagnosis in this system may lead to the development of complications and hinder sport practice. Objective: to characterize knee injuries in athletes of the sport system in the province of Cienfuegos.Methods: an observational, quantitative and qualitative, longitudinal and retrospective study was conducted. It included 104 athletes who attended the Traumatology Consultation from 2009 to 2011, presenting different types of knee injuries in various stages of training. Variables such as age, sex, sport, site of injury, stage of training, kilocalories consumed, type of training, quality of equipment and diagnosis were analyzed. The procedure used consists of a comprehensive review of case notes and medical records of all patients that attended consultation during the period analyzed, from which the necessary data was collected. Interviews with coaches and technical staff were carried out as well. Results: knee injuries occur in all ages of athletes, with a slight predominance of males. Highest frequencies are those of the ligament and meniscus, with the highest incidence in athletics, volleyball and judo. Conservative treatment predominated.Conclusions: knee injuries require a timely treatment in order to achieve athlete's success and safety.

    The prevalence of obesity and previous knee injury was assessed in a retrospective study of 115 patients under-going total knee replacement due to osteoarthritis. Obesity was considered a contributing factor in the development of osteoarthritis in 37% of the patients, and 33% of the patients had...... had an injury to the knee in question. Unilateral osteoarthritis was significantly more frequent than bilateral osteoarthritis among patients with a history of previous knee injury. The association of previous injury to the knee and unilateral osteoarthritis was stronger in men than women. Aggressive...... treatment of patients with knee injuries seems warranted....

    The use of weights is an increasingly popular conditioning technique, competitive sport and recreational activity among children, adolescents and young adults. Weight-training can cause significant musculoskeletal injuries such as fractures, dislocations, spondylolysis, spondylolisthesis, intervertebral disk herniation, and meniscal injuries of the knee. Although injuries can occur during the use of weight machines, most apparently happen during the aggressive use of free weights. Prepubescent and older athletes who are well trained and supervised appear to have low injury rates in strength training programmes. Good coaching and proper weightlifting techniques and other injury prevention methods are likely to minimise the number of musculoskeletal problems caused by weight-training.

    Full Text Available Background: Tibial and femoral fractures, commonly seen in emergency departments, may be associated with various knee ligament injuries. The aim of this study was to determine the prevalence of such fracture-associated knee ligament problems, with especial attention to rapid diagnosis. Methods: This study was carried out in patients with femoral or tibial fractures who were operated on in Imam Khomeini Medical Center from March 2003 to March 2005. All patients underwent surgical repair immediately after acute fracture, followed by a thorough knee examination. Patients with positive clinical findings were further evaluated using the stress view and arthroscopy. Results: We enrolled 470 cases in this study, of which 266 were tibial and 204 were femoral fractures. There were 404 men and 67 women, with an average age of tibial fracture patients was 34.5 and 44.6 years for those with femoral fractures. Of all fractures, 66% were due to car accidents, 16% to industrial accidents and 8% due to falling. The overall prevalence of ligament injuries in tibial fractures was as follows: 6.58% ACL tearing, 2.5% PCL, 21.95% MCL and 14.63% LCL. The overall prevalence of ligament injuries in femoral fractures was as follows: 6% ACL tearing, 3% PCL, 14% MCL and 8% LCL. Conclusion: The prevalence of ligament injuries of the knee was highest in distal femoral and tibial plateau fractures. It is prudent to perform a thorough knee examination once the fracture is stabilized in the operating room for the early detection of ligament injuries and prevention of further complications.

    Excessive physiological anterior and rotational knee laxity is thought to be a risk factor for noncontact anterior cruciate ligament (ACL) injuries and inferior reconstruction outcomes, but no thresholds have been established to identify patients with increased laxity. (1) To determine if the healthy contralateral knees of ACL-injured patients have greater anterior and rotational knee laxity, leading to different laxity profiles (combination of laxities), compared with healthy control knees and (2) to set a threshold to help discriminate anterior and rotational knee laxity between these groups. Case-sectional study; Level of evidence, 3. A total of 171 healthy contralateral knees of noncontact ACL-injured patients (ACL-H group) and 104 healthy knees of control participants (CTL group) were tested for anterior and rotational laxity. Laxity scores (measurements corrected for sex and body mass) were used to classify knees as hypolax (score 1). Proportions of patients in each group were compared using χ(2) tests. Receiver operating characteristic curves were computed to discriminate laxity between the groups. Odds ratios were calculated to determine the probability of being in the ACL-H group. The ACL-H group displayed greater laxity scores for anterior displacement and internal rotation in their uninjured knee compared with the CTL group (P knees of patients with noncontact ACL injuries display different laxity values both for internal rotation and anterior displacement compared with healthy control knees. The identification of knee laxity profiles may be of relevance for primary and secondary prevention programs of noncontact ACL injuries. © 2015 The Author(s).

    Objective We aimed to evaluate if a recent knee injury was associated with accelerated knee osteoarthritis (KOA) progression. Methods In the Osteoarthritis Initiative (OAI) we studied participants free of KOA on their baseline radiographs (Kellgren-Lawrence [KL]knee that progressed to end-stage KOA (KL Grade 3 or 4) within 48 months, 2) common KOA progression: at least one knee increased in radiographic scoring within 48 months (excluding those defined as accelerated KOA), and 3) no KOA: no change in KL grade in either knee. At baseline, participants were asked if their knees had ever been injured and at each annual visit they were asked about injuries during the prior 12 months. We used multinomial logistic regressions to determine if a new knee injury was associated with the outcome of accelerated KOA or common KOA progression after adjusting for age, sex, body mass index, static knee malalignment, and systolic blood pressure. Results A knee injury during the total observation period was associated with accelerated KOA progression (n=54, odds ratio [OR]=3.14) but not common KOA progression (n=187, OR=1.08). Furthermore, a more recent knee injury (within a year of the outcome) was associated with accelerated (OR=8.46) and common KOA progression (OR=3.12). Conclusion Recent knee injuries are associated with accelerated KOA. Most concerning is that certain injuries may be associated with a rapid cascade towards joint failure in less than one year.

    Purpose US high school athletes sustain millions of injuries annually. Detailed patterns of knee injuries, among the most costly sports injuries, remain largely unknown. We hypothesize that patterns of knee injuries in US high school sports differ by sport and gender. Methods US High school sports-related injury data were collected for 20 sports using the National High School Sports-Related Injury Surveillance System, High School RIO™. Knee injury rates, rate ratios, and injury proportion ratios were calculated. Results From 2005/06–2010/11, 5,116 knee injuries occurred during 17,172,376 athlete exposures (AEs) for an overall rate of 2.98 knee injuries per 10,000 AEs. Knee injuries were more common in competition than practice (RR 3.53, 95% CI 3.34–3.73). Football had the highest knee injury rate (6.29 per 10,000 AEs) followed by girls’ soccer (4.53) and girls’ gymnastics (4.23). Girls had significantly higher knee injury rates than boys in gender-comparable sports (soccer, volleyball, basketball, baseball/softball, lacrosse, swimming and diving, and track and field) (RR 1.52, 95% CI 1.39–1.65). The most commonly involved structure was the MCL (reported in 36.1% of knee injuries), followed by the patella/patellar tendon (29.5%), ACL (25.4%), meniscus (23.0%), LCL (7.9%), and PCL (2.4%). Girls were significantly more likely to sustain ACL injuries in gender-comparable sports (RR 2.38, 95% CI 1.91–2.95). Overall, 21.2% of knee injuries were treated with surgery; girls were more often treated with surgery than boys in gender-comparable sports (IPR 1.30, 95% CI 1.11–1.53). Conclusions Knee injury patterns differ by sport and gender. Continuing efforts to develop preventive interventions could reduce the burden of these injuries. PMID:23059869

    Non-contact anterior cruciate ligament (ACL) injuries occur with rapid decelerations and pivoting. A recent injury to a high-level National Basketball Association (NBA) player demonstrated neuromuscular control and injury-sparing mechanisms that resulted in only minor ligament injury to the medial collateral ligament. We analyzed biomechanical mechanisms via publically available orthogonal 2-D video to demonstrate how this potential ACL injury was averted. Analysis of the knee injury mechanism demonstrated that the NBA player experienced low ground reaction force, high sagittal plane flexion, and maintenance of frontal plane stability with neuromuscular control. The outcome of these factors inhibited dynamic valgus collapse of the knee throughout the fall, avoiding ACL injury - a potentially career-altering injury. Many athletes, professional and recreational, will be subjected to similar mechanisms of injury and will have improved outcomes if they can successfully utilize preventive strategies of neuromuscular control to limit injury mechanisms.

    Sidestep cutting technique is essential in programmes to prevent anterior cruciate ligament (ACL) injury. A better understanding of how technique affects potentially harmful joint loading may improve prevention programmes. The purpose of this study was to investigate the effect of sidestep cutting technique on maximum knee abduction moments. Cross-sectional study. Whole-body kinematics and knee joint kinetics were calculated in 123 female handball players (mean±SD, 22.5±7.0 years, 171±7 cm, 67±7 kg) performing sidestep cutting. Three cuts from each side were analysed. Linear regression was applied between selected technique factors and maximum knee abduction moment during the first 100 ms of the contact phase. Furthermore, we investigated to what degree the abduction moment originated from the magnitude of the ground reaction force (GRF) or the knee abduction moment arm of the GRF. Technique factors explained 62% of the variance in knee abduction moments. Cut width, knee valgus, toe landing, approach speed and cutting angle were the most significant predictors. An increase in one of these factors of 1 SD increased the knee abduction moment from 12% to 19%. The effect of the moment arm of the GRF was more important than the force magnitude for maximum knee abduction moments. Lower knee abduction loads during sidestep cutting may be achieved if cuts are performed as narrow cuts with low knee valgus and toe landings. These factors may be targeted in ACL injury prevention programmes.

    This paper evaluates 420 ski injuries occurring in Northern Sweden in 1977. Our main aim was to correlate knee injuries with types of skiing and to note a change in incidence with evolution of equipment. Fifty-eight lesions (13.8%) affected the knee joint which is about the same frequency as 10 years earlier nor has introduction of high stiff boots in downhill skiing increased incidence of knee injuries. Cross-country and long-distance skiing produced more knee injuries (24.7%) than downhill skiing (11.4%). Cross-country skiers were older and more women in this group sustained knee injuries. The use of non-release type bindings is probably the main reason for this higher incidence but age and different skiing techniques seem to contribute.

    Full Text Available Background: Osteoarthritis is the most joint disorder among elderly. There are a lot of risk factors of knee osteoarthritis. Obesity and high frequent of parity can increase the load on knee joint. Knee injury also decreases the stability of knee joint on bearing body load. This study was conducted to observe the association of obesity, parity ≥3 times and history of knee injury with the occurrence of knee osteoarthritis in female aged >50 years old. Methods: Case control design was chosen in this study. Female patients with age >50 years were recruited by consecutive sampling from rheumatology clinic at Dr. Hasan Sadikin General Hospital Bandung. Data were collected from August to September 2013. Minimal sample size was 60 samples calculated by rule of thumb formula. Obesity was measured by body mass index (BMI. Parity and history of knee injury were assessed by questionnaire. Those variables were analyzed by logistic regression method. Result: Obesity did not associate with knee osteoarthritis in this study, p=0.549 (odd ratio (OR 1.32, 95% confidence interval (CI 0.52–3.32. Parity was associated with knee osteoarthritis in this study p=0.001 (OR 4.7, 95% CI 1.89–11.68. History of knee injury was associated with knee osteoarthritis in this study, p=0.001 (OR 6.19, 95% CI 2.01–18.99. Conclusions: Parity ≥3 times and history of knee injury were associated with the occurrence of knee osteoarthritis. Obesity was not associated with the occurrence of knee osteoarthritis.

    Injury risk curves for the skeletal knee-thigh-hip (KTH) relate peak force applied to the anterior aspect of the flexed knee, the primary source of KTH injury in frontal motor-vehicle crashes, to the probability of skeletal KTH injury. Previous KTH injury risk curves have been developed from analyses of peak knee-impact force data from studies where knees of whole cadavers were impacted. However, these risk curves either neglect the effects of occupant gender, stature, and mass on KTH fracture force, or account for them using scaling factors derived from dimensional analysis without empirical support. A large amount of experimental data on the knee-impact forces associated with KTH fracture are now available, making it possible to estimate the effects of subject characteristics on skeletal KTH injury risk by statistically analyzing empirical data. Eleven studies were identified in the biomechanical literature in which the flexed knees of whole cadavers were impacted. From these, peak knee-impact force data and the associated subject characteristics were reanalyzed using survival analysis with a lognormal distribution. Results of this analysis indicate that the relationship between peak knee-impact force and the probability of KTH fracture is a function of age, total body mass, and whether the surface that loads the knee is rigid. Comparisons between injury risk curves for the midsize adult male and small adult female crash test dummies defined in previous studies and new risk curves for these sizes of occupants developed in this study suggest that previous injury risk curves generally overestimate the likelihood of KTH fracture at a given peak knee-impact force. Future work should focus on defining the relationships between impact force at the human knee and peak axial compressive forces measured by load cells in the crash test dummy KTH complex so that these new risk curves can be used with ATDs.

    Soccer is the most common sport activity worldwide. Over the last two decades the increase in soccer players has mainly been due to increased interest by females. In general, soccer is a relatively safe sport activity, especially if minor injuries resulting in short periods of absence from playing or training are neglected. However, due to the high number of soccer players severe injuries are also frequent. These are a problem not only for the injured player and the team but may also become problematic for the socio-economic system. In up to 80-90% structures of the lower extremities are injured. For sufficient radiological diagnosis knowledge of the biomechanics of the soccer game and some details about the history of the injury may be of help. To prevent soccer injuries or keep the degree of injury low, special programs had been developed. (orig.) [de

    2012-05-01

    Post-traumatic osteoarthritis (PTOA) is a process resulting from direct forces applied to a joint that cause injury and degenerative changes. An estimated 12% of all symptomatic osteoarthritis (OA) of the hip, knee, and ankle can be attributed to a post-traumatic cause. Neuromuscular prehabilitation is the process of improving neuromuscular function to prevent development of PTOA after an initial traumatic joint injury. Prehabilitation strategies include restoration of normative movement patterns that have been altered as the result of traumatic injury, along with neuromuscular exercises and gait retraining to prevent the development of OA after an injury occurs. A review of the current literature shows that no studies have been performed to evaluate methods of neuromuscular prehabilitation to prevent PTOA after a joint injury. Instead, current research has focused on management strategies after knee injuries, the value of exercise in the management of OA, and neuromuscular exercises after total knee arthroplasty. Recent work in gait retraining that alters knee joint loading holds promise for preventing the development of PTOA after joint trauma. Future research should evaluate methods of neuromuscular prehabilitation strategies in relationship to the outcome of PTOA after joint injury.

    Full Text Available Koji J Duncan, Jaclyn N Chopp-Hurley, Monica R Maly School of Rehabilitation Science, McMaster University, Hamilton, ON, Canada Purpose: Among a variety of conservative and surgical options to treat anterior cruciate ligament (ACL injuries, we do not understand which options could potentially prevent knee osteoarthritis (OA. The aim of this systematic review was to examine the evidence pertaining to exercise treatment of ACL injuries in the context of knee OA. Methods: Medline, Embase, CINAHL, PubMed, and PEDro (Physiotherapy Evidence Database databases were systematically searched using keywords encompassed within four primary key terms: knee, osteoarthritis, anterior cruciate ligament, and exercise. Clinical studies evaluating the effect of an exercise treatment for ACL injuries on the development of knee OA in adult humans were included. The PEDro scale was used to critically assess the studies included in the review. Results: Eighteen studies were included in this review, with a median PEDro score of 6/11 (range, 2/11–9/11. Three studies provided statistical evidence that exercise following ACL injury lowered the risk for knee OA development. Nine studies demonstrated no benefit of exercise in preventing knee OA incidence relative to either operative treatment or the contralateral, unaffected knee. However, exercise resulted in higher knee instability. Nonetheless, there were no significant differences in subjective or objective knee outcomes for early versus late ACL reconstruction. Limitations: This review was not registered through PROSPERO. Conclusion: The relationship between a rehabilitative exercise for ACL injuries and long-term knee OA prevalence is inconclusive. However, research suggests initial conservative treatment with optional late ACL reconstruction because this treatment strategy may reduce the risk of knee OA. More research, ideally randomized controlled trials or comparable designs, is required prior to establishing

    Objectives: Knee ligament injuries related to lower limb fractures are common and frequently unnoticed. Management of acute polytrauma is usually focused in the bone lesion and a complete physical examination might be really difficult. The purpose of this study was to analyze a series of patients who suffered multiligament knee injuries associated to a lower limb fracture. Hypothesis: The use of magnetic resonance imaging (MRI) during the initial management can lead to an early diagnosis of ligament injuries. Methods: A retrospective search was conducted from our hospital´s electronic database. We evaluated the initial diagnosis and acute surgical treatment, and management and functional outcomes after the ligament lesion was diagnosed. Results: Seven patients who presented a knee multiligament injury associated with a lower limb fracture were evaluated. The average age was 29 years. Primary diagnoses were: four tibial plateau fractures; one open fracture-dislocation of the knee; one open leg fracture and ipsilateral hip dislocation; and one bifocal femur fracture. Only three patients had an MRI during the initial management of trauma. Six out of seven patients had to be operated on for the multiligament knee injury. The period between the resolution of the fracture and the ligamentous repair was from 3 to 24 months. Conclusion: Poor functional outcomes are reported in patients with multiligament knee injuries associated with high-energy lower limb fractures. We consider an MRI during the initial management can lead to better outcomes. A trauma surgeon working alongside an arthroscopic surgeon might optimize the results for these lesions.

    Full Text Available Abstract Introduction Total knee arthroplasty is a well-established procedure with gratifying results. There is no consensus in the literature whether to routinely resurface the patella while performing total knee arthroplasty or not. Although an extremely rare occurrence in clinical practice, patellar prosthesis dislocation is a possible complication resulting from total knee arthroplasty. Case presentation We report a rare case of atraumatic spontaneous dislocation of patellar prosthesis in a 63-year-old Caucasian man of British origin with patellar tendon injury. The patient was treated successfully through a revision of the patellar component and tendon repair. In two years follow-up the patient is asymptomatic with no sign of loosening of his patellar prosthesis. Conclusions A thorough understanding of knee biomechanics is imperative in performing total knee arthroplasty in order to achieve a better functional outcome and to prevent early prosthetic failure.

    The majority of research on medial (MCL) and lateral (LCL) collateral ligament injuries has focused on adults and combined collateral/cruciate injuries. The purpose of this study was to determine characteristics associated with isolated collateral ligament injuries in adolescents, and assess timing for return to sports. Electronic medical records were queried to identify patients aged below 17 years who sustained a magnetic resonance imaging-confirmed isolated MCL or LCL injury over an 8-year period. Retrospective review then documented patient and injury characteristics and clinical course. General linear modeling was used to analyze risk factors for prolonged return to sports, continued pain or reinjury. Fifty-one knees (33 in males, 65%), mean age 13.8 years (range, 5 to 17), were identified, of which 40 (78%) had MCL injuries. Over half (29, 57%) of knees had an open distal femoral physis including all 5 bony avulsion injuries. Eleven (22%) had LCL injuries of which 3 (6%) had concurrent posterolateral corner injuries. Forty-two (82%) knees had injuries that occurred during sports. Eleven knees (28%) with MCL tears had a simultaneous patellar instability episode. Knee injuries that occurred during sports had 37% shorter recovery time (P=0.02). Eight knees (16%) experienced a reinjury and 12 (24%) were followed over an extended period of time for various knee issues. Football injuries were more likely to be grade 3 (P=0.03), and football and soccer accounted for all grade III injuries. The mean return to sports was 2.2 months, with grade III cases returning at 2.4 months, and 95% of cases within 4 months. Isolated collateral ligament injuries are rare in adolescent athletes. MCL injuries, one-quarter of which occurred in conjunction with patellar instability events, were 4 times more common than LCL injuries, one quarter of which have other posterolateral corner structures involved. Grade III injuries represent 20% to 25% of collateral ligament injuries and

    Anterior cruciate ligament (ACL) injury predisposes individuals to early-onset knee joint osteoarthritis (OA). Abnormal joint loading is apparent after ACL injury and reconstruction. The relationship between altered joint biomechanics and the development of knee OA is unknown. Altered knee joint kinetics and medial compartment contact forces initially after injury and reconstruction are associated with radiographic knee OA 5 years after reconstruction. Case-control study; Level of evidence, 3. Individuals with acute, unilateral ACL injury completed gait analysis before (baseline) and after (posttraining) preoperative rehabilitation and at 6 months, 1 year, and 2 years after reconstruction. Surface electromyographic and knee biomechanical data served as inputs to an electromyographically driven musculoskeletal model to estimate knee joint contact forces. Patients completed radiographic testing 5 years after reconstruction. Differences in knee joint kinetics and contact forces were compared between patients with and those without radiographic knee OA. Patients with OA walked with greater frontal plane interlimb differences than those without OA (nonOA) at baseline (peak knee adduction moment difference: 0.00 ± 0.08 N·m/kg·m [nonOA] vs -0.15 ± 0.09 N·m/kg·m [OA], P = .014; peak knee adduction moment impulse difference: -0.001 ± 0.032 N·m·s/kg·m [nonOA] vs -0.048 ± 0.031 N·m·s/kg·m [OA], P = .042). The involved limb knee adduction moment impulse of the group with osteoarthritis was also lower than that of the group without osteoarthritis at baseline (0.087 ± 0.023 N·m·s/kg·m [nonOA] vs 0.049 ± 0.018 N·m·s/kg·m [OA], P = .023). Significant group differences were absent at posttraining but reemerged 6 months after reconstruction (peak knee adduction moment difference: 0.02 ± 0.04 N·m/kg·m [nonOA] vs -0.06 ± 0.11 N·m/kg·m [OA], P = .043). In addition, the OA group walked with lower peak medial compartment contact forces of the involved limb

    Injuries to the knee, including intra-articular fractures, ligamentous ruptures, and meniscal and articular cartilage lesions, are commonplace within sports. Despite advancements in surgical techniques and enhanced rehabilitation, athletes returning to cutting, pivoting, and jumping sports after a knee injury are at greater risk of sustaining a second injury. The clinical utility of objective criteria presents a decision-making challenge to ensure athletes are fully rehabilitated and safe to return to sport. A system centered on specific indicators that can be used to develop a comprehensive profile to monitor rehabilitation progression and to establish return to activity criteria is recommended to clear athletes to begin a progressive and systematic approach to activities and sports. Integration of a sports knee injury performance profile with return to activity criteria can guide clinicians in facilitating an athlete's safe return to sport, prevention of subsequent injury, and life-long knee joint health.

    The arthrography is one of the most important diagnostic methods of sport injuries of the knee joint. The examination must give an exact information to the surgeon; a good technique and standard X-rays are an absolute postulate. The submitted examinations are based on 6687 arthrographies during a period of 5 years. The arthrography should not be carried out before the acute symptomatology has ceased, usually after an interval of 2-3 weeks. Most frequent are the meniscus injuries by rotary traumas of the knee-joint. Football as the most popular sport is responsible for more than 50% of the injuries, followed by skiing, handball and jogging.

    Knee injuries are frequent in children, with most studies reporting traumatic knee injuries. Evidence of risk factors for knee injuries in children is sparse. The purpose of this study was to report the extent of traumatic and overuse knee injuries in children and to evaluate intrinsic and extrinsic factors for risk of these injuries. Weekly musculoskeletal pain, sport participation, and sports type were reported by 1326 school children (8-15 yr). Knee injuries were classified as traumatic or overuse. Multinomial logistic regression was used for analyses. During the study period, 952 (15% traumatic and 85% overuse) knee injuries were diagnosed. Period prevalence for traumatic and overuse knee injuries were 0.8/1000 and 5.4/1000 sport participations, respectively. Participation in tumbling gymnastics was a risk factor for traumatic knee injuries (OR, 2.14). For overuse knee injuries, intrinsic risk factors were sex (girls OR, 1.38) and previous knee injury (OR, 1.78), whereas participation in soccer (OR, 1.64), handball (OR, 1.95), basket (OR, 2.07), rhythmic (OR, 1.98), and tumbling gymnastics (OR, 1.74) were additional risk factors. For both injury types, sport participation above two times per week increased odds (OR, 1.46-2.40). Overuse knee injuries were the most frequent injury type. For traumatic knee injuries, participation in tumbling gymnastics was a risk factor. Risk factors for overuse knee injuries were being a girl; previous knee injury; and participation in soccer, handball, basket, and rhythmic and tumbling gymnastics. Further risk factors for both types of injury were participation in sports above two times per week. Although growth-related overuse knee injuries are a self-limiting condition, a major part of children are affected by these injuries with unknown short- and long-term consequences.

    Children and adolescents are now participating in competitive sports at younger ages and with increasing intensity. As a result, increasing numbers of young athletes are presenting to pediatricians for care of sports-related injuries and advice about prevention. Understanding and identifying modifiable risk factors for injury in the young athletic population is a critical first step in injury prevention. Risk factors vary by sport, age, and sex. This article reviews the most common risk factors for injury and the evidence to support proposed strategies for prevention. [Pediatr Ann. 2017;46(3):e99-e105.]. Copyright 2017, SLACK Incorporated.

    Currently, there is no overview of the incidence and (volleyball-specific) risk factors of musculoskeletal injuries among volleyball players, nor any insight into the effect of preventive measures on the incidence of injuries in volleyball. This study aimed to review systematically the scientific evidence on the incidence, prevalence, aetiology and preventive measures of volleyball injuries. To this end, a highly sensitive search strategy was built based on two groups of keywords (and their synonyms). Two electronic databases were searched, namely Medline (biomedical literature) via Pubmed, and SPORTDiscus (sports and sports medicine literature) via EBSCOhost. The results showed that ankle, knee and shoulder injuries are the most common injuries sustained while playing volleyball. Results are presented separately for acute and overuse injuries, as well as for contact and non-contact injuries. Measures to prevent musculoskeletal injuries, anterior knee injuries and ankle injuries were identified in the scientific literature. These preventive measures were found to have a significant effect on decreasing the occurrence of volleyball injuries (for instance on ankle injuries with a reduction from 0.9 to 0.5 injuries per 1000 player hours). Our systematic review showed that musculoskeletal injuries are common among volleyball players, while effective preventive measures remain scarce. Further epidemiological studies should focus on other specific injuries besides knee and ankle injuries, and should also report their prevalence and not only the incidence. Additionally, high-quality studies on the aetiology and prevention of shoulder injuries are lacking and should be a focus of future studies.

    American flag football is a non-tackle, contact sport with many moderate to severe contact-type injuries reported. A previous prospective injury surveillance study by the authors revealed a high incidence of injuries to the fingers, face, knee, shoulder and ankle. The objectives of the study were to conduct a pilot-prospective injury prevention study in an attempt to significantly reduce the incidence and the severity of injuries as compared to a historical cohort, as well as to provide recommendations for a future prospective injury prevention study. A prospective injury prevention study was conducted involving 724 amateur male (mean age: 20.0 ± 3.1 years) and 114 female (mean age: 21.2 ± 7.2 years) players. Four prevention measures were implemented: the no-pocket rule, self-fitting mouth guards, ankle braces (for those players with recurrent ankle sprains) and an injury treatment information brochure. An injury surveillance questionnaire was administered to record all time-loss injuries sustained in game sessions. There was a statistically significant reduction in the number of injured players, the number of finger/hand injuries, the incidence rate and the incidence proportion between the two cohorts (p football. Prevention strategies for a longer, prospective, randomised-controlled injury prevention study should include the strict enforcement of the no-pocket rule, appropriate head gear, the use of comfortable-fitting ankle braces and mouth guards, and changing the blocking rules of the game.

    High school cross country runners have a high incidence of overuse injuries, particularly to the knee and shin. As lower extremity strength is modifiable, identification of strength attributes that contribute to anterior knee pain (AKP) and shin injuries may influence prevention and management of these injuries. To determine if a relationship existed between isometric hip abductor, knee extensor and flexor strength and the incidence of AKP and shin injury in high school cross country runners. Sixty-eight high school cross country runners (47 girls, 21 boys) participated in the study. Isometric strength tests of hip abductors, knee extensors and flexors were performed with a handheld dynamometer. Runners were prospectively followed during the 2014 interscholastic cross country season for occurrences of AKP and shin injury. Bivariate logistic regression was used to examine risk relationships between strength values and occurrence of AKP and shin injury. During the season, three (4.4%) runners experienced AKP and 13 (19.1%) runners incurred a shin injury. Runners in the tertiles indicating weakest hip abductor (chi-square = 6.140; p=0.046), knee extensor (chi-square = 6.562; p=0.038), and knee flexor (chi-square = 6.140; p=0.046) muscle strength had a significantly higher incidence of AKP. Hip and knee muscle strength was not significantly associated with shin injury. High school cross country runners with weaker hip abductor, knee extensor and flexor muscle strength had a higher incidence of AKP. Increasing hip and knee muscle strength may reduce the likelihood of AKP in high school cross country runners. 2b.

    We have investigated iatrogenic popliteal artery injuries (PAI) during non arthroplasty knee surgery regarding mechanism of injury, treatment and outcomes, and to identify successful strategies when injury occurs. In all, 21 iatrogenic popliteal artery injuries in 21 patients during knee surgery other than knee arthroplasty were identified from the Swedish Vascular Registry (Swedvasc) between 1987 and 2011. Prospective registry data were supplemented with case-records, including long-term follow-up. In total, 13 patients suffered PAI during elective surgery and eight during urgent surgery such as fracture fixation or tumour resection. Nine injuries were detected intra-operatively, five within 12 to 48 hours and seven > 48 hours post-operatively (two days to 23 years). There were 19 open vascular and two endovascular surgical repairs. Two patients died within six months of surgery. One patient required amputation. Only six patients had a complete recovery of whom had the vascular injury detected at time of injury and repaired by a vascular surgeon. Patients sustaining vascular injury during elective procedures are more likely to litigate (p = 0.029). We conclude that outcomes are poorer when there is a delay of diagnosis and treatment, and that orthopaedic surgeons should develop strategies to detect PAI early and ensure rapid access to vascular surgical support. ©2015 The British Editorial Society of Bone & Joint Surgery.

    The appearances of knee injuries on MR imaging are less well documented in children than adults. Some patterns of injury are shared by both groups of patients, e. g. meniscal damage. The frequency of specific injuries may differ, e. g. anterior cruciate ligament (ACL) tear. Congenital abnormality, coexistent pathology and previous treatment of the knee appear to be associated with meniscal problems. Discoid menisci are seen most frequently in children and have unique features on MR scans. Cruciate ligament tears are difficult to diagnose in the smallest children. The ACL may not be identified due to its small size. Normal bone marrow signal may be confused with marrow infiltration or bone microfracture. Radiographically occult fractures around the knee appear to be strongly associated with ligamentous injury as in adult patients. Osteochondral fractures, osteochondral lesions and articular cartilage damage are revealed on MR scans, but their long-term effects are uncertain. It is possible to diagnose a range of knee injuries on MR scans in children. The biggest diagnostic challenge is in pre-school children. (orig.). With 9 figs., 1 tab

    Background Floating knee injuries are usually associated with other significant injuries. Do these injuries have implications on the management of the floating knee and the final outcome of patients? Our study aims to assess the implications of associated injuries in the management and final outcome of floating knee. Methods 29 patients with floating knees were assessed in our institution. A retrospective analysis of medical records and radiographs were done and all associated injuries were identified. The impact of associated injuries on delay in initial surgical management, delay in rehabilitation & final outcome of the floating knee were assessed. Results 38 associated injuries were noted. 7 were associated with ipsilateral knee injuries. Lower limb injuries were most commonly associated with the floating knee. Patients with some associated injuries had a delay in surgical management and others a delay in post-operative rehabilitation. Knee ligament and vascular injuries were associated with poor outcome. Conclusion The associated injuries were quite frequent with the floating knee. Some of the associated injuries caused a delay in surgical management and post-operative rehabilitation. In assessment of the final outcome, patients with associated knee and vascular injuries had a poor prognosis. Majority of the patients with associated injuries had a good or excellent outcome.

    Previous study has shown a likely link between increased shoe- surface traction and risk of knee Anterior Cruciate Ligament (ACL) injury. Portable natural grass systems are being used more often in sport, but no study to date has investigated their relative safety. By their nature, they must have high resistance to falling apart and therefore newly laid systems may be at risk of creating excessive shoe-surface traction. This study describes two clusters of knee injuries (particularly non-contact ACL injuries), each occurring to players of one professional football team at single venue, using portable grass, in a short space of time. The first series included two ACL injuries, one posterolateral complex disruption and one lateral ligament tear occurring in two rugby league games on a portable bermudagrass surface in Brisbane, Australia. The second series included four non-contact ACL injuries over a period of ten weeks in professional soccer games on a portable Kentucky bluegrass/perennial ryegrass surface in Barcelona, Spain. Possible intrinsic risk factors are discussed but there was no common risk shared by the players. Although no measures of traction were made at the Brisbane venue, average rotational traction was measured towards the end of the injury cluster at Camp Nou, Barcelona, to be 48 Nm. Chance undoubtedly had a part to play in these clusters, but the only obvious common risk factor was play on a portable natural grass surface soon after it was laid. Further study is required to determine whether portable natural grass systems may exhibit high shoe-surface traction soon after being laid and whether this could be a risk factor for knee injury. Key pointsExcessive shoe-surface traction is a hypothesised risk factor for knee ligament injuries, including anterior cruciate ligament injuries.Portable natural grass systems (by their nature in order to prevent grass rolls or squares from falling apart) will tend to exhibit high resistance to tearing when first

    The largest number of injuries of the knee occurrs in athletes. The portion of girls has reached 30%. More than 50% of all injuries regard the ligaments and the menisci. Especially in these cases and in combined lesions, arthrography gives good results. All possibilities of investigations should be used for acutely injured sportsmen because of the specific risks and the dissimulation of young sportspeople and because of the danger of late established diagnosis and within those of late damages.

    With concerns increasing around childhood obesity and inactivity, playgrounds offer a chance for children to be active. But playgrounds also have risks, with injuries from falls being the most common. Research has shown that playground injuries can be reduced by lowering the heights of play equipment and using soft, deep surfaces to cushion falls. The Canadian Standards Association has published voluntary standards for playgrounds to address these risks for several years. Parents can further reduce injury risks by following simple playground strategies. This statement outlines the burden of playground injuries. It also provides parents and health care providers with opportunities to reduce injury incidence and severity through education and advocacy, and to implement evidence-informed safety standards and safer play strategies in local playgrounds. This document replaces a previous Canadian Paediatric Society position statement published in 2002.

    Full Text Available Abstract Background Musculoskeletal disorders (MSDs affect a large proportion of the Canadian population and present a huge problem that continues to strain primary healthcare resources. Currently, the Canadian healthcare system depicts a clinical care pathway for MSDs that is inefficient and ineffective. Therefore, a new inter-disciplinary team-based model of care for managing acute knee injuries was developed in Calgary, Alberta, Canada: the Calgary Acute Knee Injury Clinic (C-AKIC. The goal of this paper is to evaluate and report on the appropriateness, efficiency, and effectiveness of the C-AKIC through healthcare utilization and costs associated with acute knee injuries. Methods This quasi-experimental study measured and evaluated cost and utilization associated with specific healthcare services for patients presenting with acute knee injuries. The goal was to compare patients receiving care from two clinical care pathways: the existing pathway (i.e. comparison group and a new model, the C-AKIC (i.e. experimental group. This was accomplished through the use of a Healthcare Access and Patient Satisfaction Questionnaire (HAPSQ. Results Data from 138 questionnaires were analyzed in the experimental group and 136 in the comparison group. A post-hoc analysis determined that both groups were statistically similar in socio-demographic characteristics. With respect to utilization, patients receiving care through the C-AKIC used significantly less resources. Overall, patients receiving care through the C-AKIC incurred 37% of the cost of patients with knee injuries in the comparison group and significantly incurred less costs when compared to the comparison group. The total aggregate average cost for the C-AKIC group was $2,549.59 compared to $6,954.33 for the comparison group (p Conclusions The Calgary Acute Knee Injury Clinic was able to manage and treat knee injured patients for less cost than the existing state of healthcare delivery.

    Full Text Available Injuries are one of the most under-recognized public health problems facing the world today. With more than 5 million deaths every year, violence and injuries account for 9% of global mortality, as many deaths as from HIV, Malaria and Tuberculosis combined. Eight of the 15 leading causes of death for people ages 15 to 29 years are injury-related: road traffic injuries, suicides, homicides, drowning, burns, war injuries, poisonings and falls. For every death due to war, there are three deaths due to homicide and five deaths due to suicide. However, most violence happens to people behind closed doors and results not in death, but often in years of physical and emotional suffering [1]. Injuries can be classified by intent: unintentional or intentional. Traffic injuries, fire-related injuries, falls, drowning, and poisonings are most often classified as unintentional injuries; injuries due to assault, selfinflicted violence such as suicide, and war are classified as intentional injuries, or violence. Worldwide, governments and public and private partners are increasingly aware of the strains that unintentional injuries and violence place on societies. In response they are strengthening data collection systems, improving services for victims and survivors, and increasing prevention efforts [1].

    Full Text Available We describe a series of three patients who sustained patella tendon injuries in infected TKAs following the use of a static cement spacer at first-stage knee revision. The patella tendon injuries resulted in significant compromise to wound healing and knee stability requiring multiple surgeries. The mid-term function was poor with an Oxford score at 24 months ranging from 12-20. Based on our experience, we advise caution in the use of static cement spacer blocks. If they are to be used, we recommend that they should be keyed in the bone to prevent patella tendon injuries.

    The motions causing noncontact anterior cruciate ligament (ACL) injury remain unclear. Tibiofemoral bone bruises are believed to be the result of joint impact near the time of ACL rupture. The locations and frequencies of these bone bruises have been reported, but there are limited data quantifying knee position and orientation near the time of injury based on these contusions. Knee position and orientation near the time of noncontact ACL injury include extension and anterior tibial translation. Descriptive laboratory study. Magnetic resonance images of 8 subjects with noncontact ACL injuries were acquired within 1 month of injury and were subsequently analyzed. All subjects exhibited bruises on both the femur and tibia in both medial and lateral compartments. The outer margins of bone and the bone bruise surfaces were outlined on each image to create a 3-dimensional model of each subject's knee in its position during magnetic resonance imaging (MRI position). Numerical optimization was used to maximize overlap of the bone bruises on the femur and tibia and to predict the position of injury. Flexion angle, valgus orientation, internal tibial rotation, and anterior tibial translation were measured in both the MRI position and the predicted position of injury. Differences in kinematics between the MRI position, which served as an unloaded reference, and the predicted position of injury were compared by use of paired t tests. Flexion angle was near full extension in both the MRI position and the predicted position of injury (8° vs 12°; P = .2). Statistically significant increases in valgus orientation (5°; P = .003), internal tibial rotation (15°; P = .003), and anterior tibial translation (22 mm; P injury relative to the MRI position. These results suggest that for the bone bruise pattern studied, landing on an extended knee is a high risk for ACL injury. Extension was accompanied by increased anterior tibial translation (22 mm), internal tibial rotation (15

    Interpretation of medical infrared images is complex due to thermal noise, absence of texture, and small temperature differences in pathological zones. Acute inflammatory response is a characteristic symptom of some knee injuries like anterior cruciate ligament sprains, muscle or tendons strains, and meniscus tear. Whereas artificial coloring of the original grey level images may allow to visually assess the extent inflammation in the area, their automated segmentation remains a challenging problem. This paper presents a hybrid segmentation algorithm to evaluate the extent of inflammation after knee injury, in terms of temperature variations and surface shape. It is based on the intersection of rapid color segmentation and homogeneous region segmentation, to which a Laplacian of a Gaussian filter is applied. While rapid color segmentation enables to properly detect the observed core of swollen area, homogeneous region segmentation identifies possible inflammation zones, combining homogeneous grey level and hue area segmentation. The hybrid segmentation algorithm compares the potential inflammation regions partially detected by each method to identify overlapping areas. Noise filtering and edge segmentation are then applied to common zones in order to segment the swelling surfaces of the injury. Experimental results on images of a patient with anterior cruciate ligament sprain show the improved performance of the hybrid algorithm with respect to its separated components. The main contribution of this work is a meaningful automatic segmentation of abnormal skin temperature variations on infrared thermography images of knee injury swelling.

    Individuals with post-traumatic osteoarthritis demonstrate increased sway during quiet stance. The prospective association between balance and disease onset is unknown. Improved understanding of balance in the period between joint injury and disease onset could inform secondary prevention strategies to prevent or delay the disease. This study examines the association between youth sport-related knee injury and balance, 3-10years post-injury. Participants included 50 individuals (ages 15-26years) with a sport-related intra-articular knee injury sustained 3-10years previously and 50 uninjured age-, sex- and sport-matched controls. Force-plate measures during single-limb stance (center-of-pressure 95% ellipse-area, path length, excursion, entropic half-life) and field-based balance scores (triple single-leg hop, star-excursion, unipedal dynamic balance) were collected. Descriptive statistics (mean within-pair difference; 95% confidence intervals) were used to compare groups. Linear regression (adjusted for injury history) was used to assess the relationship between ellipse-area and field-based scores. Injured participants on average demonstrated greater medio-lateral excursion [mean within-pair difference (95% confidence interval); 2.8mm (1.0, 4.5)], more regular medio-lateral position [10ms (2, 18)], and shorter triple single-leg hop distances [-30.9% (-8.1, -53.7)] than controls, while no between group differences existed for the remaining outcomes. After taking into consideration injury history, triple single leg hop scores demonstrated a linear association with ellipse area (β=0.52, 95% confidence interval 0.01, 1.01). On average the injured participants adjusted their position less frequently and demonstrated a larger magnitude of movement during single-limb stance compared to controls. These findings support the evaluation of balance outcomes in the period between knee injury and post-traumatic osteoarthritis onset. Copyright © 2015 Elsevier Ltd. All rights

    In this we study identified potential risk factors for post-total knee arthroplasty (TKA) nerve injury, a catastrophic complication with a reported incidence of 0.3%-1.3%. Patients who developed post-TKA nerve injury from 1998 to 2013 were identified, and each was matched with 2 controls. A multivariable logistic regression model was built to calculate odds ratios (ORs). Sixty-five nerve injury cases were identified in 39,990 TKAs (0.16%). Females (OR 3.28, P = 0.003) and patients with history of lumbar pathology (OR 6.12, P = 0.026) were associated with increased risk of nerve injury. Tourniquet pressure nerve injury was unexpected and requires further investigation. Muscle Nerve 57: 946-950, 2018. © 2017 Wiley Periodicals, Inc.

    Objective: To study the MRI manifestation of acute articular cartilage injury of knee for evaluating the extension and degree of the injury and guiding treatment. Methods: MRI of 34 patients with acute articular cartilage injury of knee within one day to fifteen days confirmed by arthroscopy and arthrotomy was reviewed and analyzed, with emphasis on articular cartilage and subchondral lesion. And every manifestation on MRI and that of arthroscopy and operation was compared. Results: The articular cartilage injury was diagnosed on MRI in 29 of 34 cases. Cartilage signal changes were found only in 4. The changes of cartilage shape were variable. Thinning of focal cartilage was showed in 3, osteochondral impaction in 3, creases of cartilage in 3, disrupted cartilage with fissuring in 13, cracks cartilage in 2, and cracks cartilage with displaced fragment in 1. Bone bruise and occult fracture were found only on MRI. Conclusion: The assessment of MRI and arthroscopy in acute articular cartilage injury are consistent. Combined with arthroscopy, MRI can succeed in assessing the extension and degree of acute articular injury and allowing treatment planning

    Unintentional injury accounts for 40 percent of childhood deaths annually, most commonly from motor vehicle crashes. The proper use of child restraints is the most effective strategy to prevent injury or death. Motor vehicle restraint guidelines have recently been revised to an age-based system that delays the progression in type of restraint for most children. Strategies to prevent suffocation in children include using appropriate bedding, positioning babies on their backs to sleep, and removing items from the sleep and play environment that could potentially entrap or entangle the child. Fencing that isolates a swimming pool from the yard and surrounding area and "touch" adult supervision (i.e., an adult is in the water and able to reach and grab a child) have been shown to be most effective in preventing drownings. Swimming lessons are recommended for children older than four years. Poison prevention programs have been shown to improve prevention behavior among caregivers, but may not decrease poisoning incidence. Syrup of ipecac is not recommended. Smoke detector maintenance, a home escape plan, and educating children about how to respond during a fire emergency are effective strategies for preventing fire injuries or death. Fall injuries may be reduced by not using walkers for infants and toddlers or bunk beds for children six years and younger. Consistent helmet use while bicycling reduces head and brain injuries. Although direct counseling by physicians appears to improve some parental safety behaviors, its effect on reducing childhood injuries is uncertain. Community-based interventions can be effective in high-risk populations.

    In the first age (1895 - 1940), radiation injuries of skin (75% of death caused by RI injury) and chronic radiation injury of heamatopoietic organs (almost remains) appeared in radiologist and people engaged in RI treatment for medical use, and Ra poisoning appeared in workers who treated aluminous paint. As prevention of radiation injuries in this age, measurement of radiation dose, shelter effect and finding of injuries were studied, and internal radiation allowed level was determined. From 1942 to 1960, acute RI injuries due to exposure of large amount of RI by an accident and secondary leukemia appeared to workers of atomic-bomb industries and researcher of atomic energy. U and Pu poisoning accompanied with development of nuclear fuel industry appeared. This expanded industrial hygiene of this age together with epidemiological data of atomic-bomb exposed people. From 1960 onward, it is an age of industry for peaceful use of atomic energy, and manifestation of various kinds of delayed injuries, especially malignant tumor due to RI exposure, is recognized. Labourer has many opportunity to encounter dangerously with pollution and injuries by RI, and regional examination of RI enterprise and countermeasure to decrease exposure dose were mentioned as future theme from a viewpoint of exposure dose of nation.

    The biggest number of injuries of the knee are in highly result interested sportsmen. The portion of girls has reached 30%. More than 50% of all injuries regard the ligaments and the menisci. Especially in these cases and in combined lesions gives the arthrography good results. All possibilities of investigations should be used for acute injured sportsmen, because of the specific readiness of risks and the dissimulation of young sportspeople and because of the danger of too late established diagnosis and within those of late damages.

    The mechanism for noncontact anterior cruciate ligament injury is still a matter of controversy. Video analysis of injury tapes is the only method available to extract biomechanical information from actual anterior cruciate ligament injury cases. This article describes 3-dimensional knee joint kinematics in anterior cruciate ligament injury situations using a model-based image-matching technique. Case series; Level of evidence, 4. Ten anterior cruciate ligament injury video sequences from women's handball and basketball were analyzed using the model-based image-matching method. The mean knee flexion angle among the 10 cases was 23° (range, 11°-30°) at initial contact (IC) and had increased by 24° (95% confidence interval [CI], 19°-29°) within the following 40 milliseconds. The mean valgus angle was neutral (range, -2° to 3°) at IC, but had increased by 12° (95% CI, 10°-13°) 40 milliseconds later. The knee was externally rotated 5° (range, -5° to 12°) at IC, but rotated internally by 8° (95% CI, 2°-14°) during the first 40 milliseconds, followed by external rotation of 17° (95% CI, 13°-22°). The mean peak vertical ground-reaction force was 3.2 times body weight (95% CI, 2.7-3.7), and occurred at 40 milliseconds after IC (range, 0-83). Based on when the sudden changes in joint angular motion and the peak vertical ground-reaction force occurred, it is likely that the anterior cruciate ligament injury occurred approximately 40 milliseconds after IC. The kinematic patterns were surprisingly consistent among the 10 cases. All players had immediate valgus motion within 40 milliseconds after IC. Moreover, the tibia rotated internally during the first 40 milliseconds and then external rotation was observed, possibly after the anterior cruciate ligament had torn. These results suggest that valgus loading is a contributing factor in the anterior cruciate ligament injury mechanism and that internal tibial rotation is coupled with valgus motion. Prevention

    Full Text Available The examined group was composed of 60 patients with injuries of Anterior Cruciate Ligament (ACL treated at the Clinical Center of Montenegro from 2006- 2010. Among general population the frequency is 1:3000, and around 70% of ACL injuries occur as a consequence of sports activity. These traumas represent 15-30% of all sports injuries. Normal kinematics of a knee joint means intact ligament. The purpose of our work was to determine the risk factors of injury, regarding training and competing process, daily activity and their connection with the mechanism of injury. In our inquiry, recreational athletes represented 70% of patients.The most common mechanism of injury is a non-contact, deceleration, valgus angulation with an external rotation as a consequence of landing, sudden change of direction, running rhythm, or fall. The largest number of injuries occurs in training, recreation, tournaments, and everyday activities. In diagnostics we employed clinical tests, ECHO finding, NMR and arthroscopy. Sports activity during which our patients obtained most of their injuries is soccer. Traumas were frequently followed by damages to their joint structures (meniscus, cartilage. Injuries of ACL are multifactorial etiologies, but through external and internal factors, adequate communication, and sports culture of partakers (athletes, trainers and physicians can be acted preventively on decreasing injury incidence and timely and adequate treatment

    To assess the value of MR imaging in the diagnosis of medial collateral ligament injury of the knee, we used MR imaging to evaluate the characteristic findings in MCL tears and the frequency of associated knee joint injury. We retrospectively reviewed 26 patients within four weeks of MCL injury, analysed MR findings and correlated them with surgical findings. We evaluated discontinuity, heterogeneous signal intensity of MCL, thin band- like low signal intensity at MCL, facial edema, loss of clear demarcation of adjacent fat also combined bone injury, meniscus injury and other ligament injury. Complete MCL tears were present in 14 patients and partial tears in 12. Complete tears showed discontinuity of MCL, fascial edema and loss of clear demarcation from adjacent fat in 11 patients(79%);proximal MCL tears are more common than distal tears. Partial tears showed thin band-like low signal intensity within MCL, fascial edema and loss of clear demarcation from adjacent fat in seven patients (58%);all patient s with MCL injury showed fascial edema;in 12 patients there was loss of clear demarcation from adjacent fat. We could not, however, distinguish between complete tears and partial tears when MCL showed heterogeneous high signal intensity. Combined bone injury in MCL tears was found in eight patients(62%);the most common sites of this were the lateral femoral condyle and lateral tibial plateau. There was associated injury involving other ligaments(ACL:50%;PCL:27%). Combined meniscus injury in MCL tears was present in 17 patients and the most common meniscus site(50%) is the posterior horn of the medial meniscus. Complete MCL tears showed discontinuity of MCL and partial tears showed a thin band-like low signal intensity within MCL. All patients with MCL injury showed fascial edema, and loss of clear demarcation from adjacent fat. Various other injuries combine with MCL tears. MR imaging is therefore useful in the evaluation of medial collateral ligament injury and

    To determine the association between traumatic bone marrow abnormalities, the knee injury mechanism, and associated soft tissue injuries in a larger cohort than those in the published literature. Retrospective study including 220 patients with traumatic knee injuries. Knee MRIs were evaluated for trauma mechanism, soft tissue injury, and the location of bone marrow abnormalities. The locations of the abnormalities were correlated with trauma mechanisms and soft tissue injuries using the chi-square test with Bonferroni correction. One hundred and forty-four valgus injuries, 39 pivot shift injuries, 25 lateral patellar dislocations, 8 hyperextensions, and 4 dashboard injuries were included. Valgus and pivot shift injuries showed traumatic bone marrow abnormalities in the posterolateral regions of the tibia. Abnormalities after patellar dislocation were found in the anterolateral and centrolateral femur and patella. Hyperextension injuries were associated with abnormalities in almost all regions, and dashboard injuries were associated with changes in the anterior regions of the tibia and femur. Our study provides evidence of associations between traumatic bone marrow abnormality patterns and different trauma mechanisms in acute knee injury, and reveals some overlap, especially of the two most common trauma mechanisms (valgus and pivot shift), in a large patient cohort.

    To establish whether patterns of soft tissue injury following knee hyperextension are associated with post-traumatic 'bone bruise' distribution. Patients with a knee MRI within one year of hyperextension injury were identified at our institution over a 7 year period. MRIs, plain radiographs and clinical details of these patients were reviewed. Twenty-five patients were identified (median time from injury to MRI = 24 days). The most common sites of bone bruising were the anteromedial tibial plateau (48%) and anterolateral tibial plateau (44%). There were high rates of injury to the posterior capsule (52%), ACL (40%) and PCL (40%) but lower rates of injury to the menisci (20%), medial and lateral collateral ligaments (16%) and posterolateral corner (16%). Anterior tibial plateau oedema and rupture of the posterior capsule predicted cruciate ligament injury [OR = 10.5 (p = 0.02) and 24.0 (p = 0.001) respectively]. Whilst anterolateral tibial plateau oedema strongly predicted PCL injury [OR = 26.0, p = 0.003], ACL injury was associated with a variable pattern of bone bruising. Meniscal injury was unrelated to the extent or pattern of bone bruising. 5 out of 8 patients with a 'double sulcus' on the lateral radiograph had ACL injury. The presence of a double sulcus showed significant association with anteromedial kissing contusions (OR = 7.8, p = 0.03). Following knee hyperextension, bone bruising patterns may be associated with cruciate ligament injury. Other structures are injured less frequently and have weaker associations with bone bruise distribution. The double sulcus sign is a radiographic marker that confers a high probability of ACL injury.

    Full Text Available Abstract The Knee injury and Osteoarthritis Outcome Score (KOOS was developed as an extension of the WOMAC Osteoarthritis Index with the purpose of evaluating short-term and long-term symptoms and function in subjects with knee injury and osteoarthritis. The KOOS holds five separately scored subscales: Pain, other Symptoms, Function in daily living (ADL, Function in Sport and Recreation (Sport/Rec, and knee-related Quality of Life (QOL. The KOOS has been validated for several orthopaedic interventions such as anterior cruciate ligament reconstruction, meniscectomy and total knee replacement. In addition the instrument has been used to evaluate physical therapy, nutritional supplementation and glucosamine supplementation. The effect size is generally largest for the subscale QOL followed by the subscale Pain. The KOOS is a valid, reliable and responsive self-administered instrument that can be used for short-term and long-term follow-up of several types of knee injury including osteoarthritis. The measure is relatively new and further use of the instrument will add knowledge and suggest areas that need to be further explored and improved.

    The medial collateral ligament (MCL) is the most commonly injured ligament of the knee. There is a spectrum of injury severity, and injuries may be acute or chronic. The MCL is also frequently injured in conjunction with other knee structures. Clinical evaluation of the knee is important to assess the degree of surgical acuity, but magnetic resonance imaging can provide details about the injury that may not be obvious clinically. In addition to injury, MCL bursitis can occur and may be treated with needle aspiration and corticosteroid injection. This review article covers the anatomy and biomechanics of the MCL, its injury patterns and approach to management, and MCL bursitis.

    Full Text Available Paraffin (called kerosene in North America and other parts of the world is the most commonly used fuel in ‎non-electrified dwellings worldwide. It is especially popular in Africa and South Asia. Although paraffin ‎offers many advantages – especially its comparatively low cost to produce – it poses two major risks of ‎injury. First, paraffin poisoning is common, either through ingestion or through inhalation of smoke and ‎fumes. Second, paraffin is highly flammable, and poses fire risk through multiple causes. This commentary ‎discusses strategies to prevent paraffin-related injury. Prevention of paraffin-related injury must be through ‎multiple strategies, and should include policy-oriented change, changes to the safety of home environments, ‎and behavioral changes targeting how individuals store and use paraffin and paraffin appliances. We review ‎successful prevention strategies in each of these domains and discuss appropriate research and community ‎initiatives that should be implemented to improve paraffin safety among at-risk populations.‎

  9. Automated Assessment of Dynamic Knee Valgus and Risk of Knee Injury During the Single Leg Squat

    Lee, Alexander; Raina, Sachin; Kulić, Dana

    2017-01-01

    Many clinical assessment protocols of the lower limb rely on the evaluation of functional movement tests such as the single leg squat (SLS), which are often assessed visually. Visual assessment is subjective and depends on the experience of the clinician. In this paper, an inertial measurement unit (IMU)-based method for automated assessment of squat quality is proposed to provide clinicians with a quantitative measure of SLS performance. A set of three IMUs was used to estimate the joint angles, velocities, and accelerations of the squatting leg. Statistical time domain features were generated from these measurements. The most informative features were used for classifier training. A data set of SLS performed by healthy participants was collected and labeled by three expert clinical raters using two different labeling criteria: “observed amount of knee valgus” and “overall risk of injury”. The results showed that both flexion at the hip and knee, as well as hip and ankle internal rotation are discriminative features, and that participants with “poor” squats bend the hip and knee less than those with better squat performance. Furthermore, improved classification performance is achieved for females by training separate classifiers stratified by gender. Classification results showed excellent accuracy, 95.7 % for classifying squat quality as “poor” or “good” and 94.6% for differentiating between high and no risk of injury. PMID:29204327

    Magnetic Resonance (MR) imaging was employed to evaluate muscoloskeletal pathoanathomy, and proved to be extremely useful in characterizing knee pathology. Between October 1986 and Novembre 1987, 24 patients with suspected traumatic ligament injuries were examined with high resolution MR imaging in the RMRC diagnostic center, Naples, with a 0.5T superconducting magnet ( 5000 Magniscan CGR) using a surface coil and a 500/28 (repetition time: TR: ms/echo time: TE-ms), 1200-1600/35-105 spin-echo pulse sequence. Nineteen patients with positive MR imaging exams underwent diagnostic and/or therapeutic arthroscopy. Arthroscopy confirmed MR diagnosis in the whole of cases. In 6 patients with negative MR findings no arthroscopy followed and the patients' successful outcome confirmed the accuracy of MR negative predictive value. Such results prove MR imaging to have a high diagnostic accuracy in the evaluation of acute joint injuries of the knee.Moreover, MR imaging-an uninvasive screening technique-appears to have high potentials for the evaluation of those cases where diagnostic arthroscopy is not required

    Economic and societal pressures influence modern medical practice to develop and implement prevention strategies. Anterior cruciate ligament (ACL) injury devastates the knee joint leading to short term disability and long term sequelae. Due to the high risk of long term osteoarthritis in all treatment populations following ACL injury, prevention is the only effective intervention for this life-altering disruption in knee health. The “Sequence of Prevention” Model provides a framework to monitor progress towards the ultimate goal of preventing ACL injuries. Utilizing this model, our multidisciplinary collaborative research team has spent the last decade working to delineate injury mechanisms, identify injury risk factors, predict which athletes are at-risk for injury, and develop ACL injury prevention programs. Within this model of injury prevention, modifiable factors (biomechanical and neuromuscular) related to injury mechanisms likely provide the best opportunity for intervention strategies aimed to decrease the risk of ACL injury, particularly in female athletes. Knowledge advancements have led to the development of potential solutions that allow athletes to compete with lowered risk of ACL injury. Design and integration of personalized clinical assessment tools and targeted prevention strategies for athletes at high risk for ACL injury may transform current prevention practices and ultimately significantly reduce ACL injury incidence. This 2016 OREF Clinical Research Award focuses on the authors' work and contributions to the field. The author's acknowledge the many research groups who have contributed to the current state of knowledge in the fields of ACL injury mechanisms, injury risk screening and injury prevention strategies.

    Rugby league is the main professional team sport played in Eastern Australia. It is also very popular at a junior and amateur level. However, injuries are common because of the amount of body contact that occurs and the amount of running that is required to participate in the game. Injuries to the lower limbs account for over 50% of all injuries. The most common specific injuries are ankle lateral ligament tears, knee medial collateral and anterior cruciate ligament tears, groin musculotendinous tears, hamstring and calf muscle tears, and quadriceps muscle contusions. Head injuries are common and consist of varying degrees of concussion as well as lacerations and facial fractures. Serious head injury is rare. Some of the more common upper limb injuries are to the acromioclavicular and glenohumeral joints. Accurate diagnosis of these common injuries using appropriate history, examination and investigations is critical in organising a treatment and rehabilitation plan that will return the player to competition as soon as possible. An understanding of the mechanism of injury is also important in order to develop preventative strategies.

    Current evidence suggests that, despite returning to full participation, physically active adults with a previous knee injury experience lower health-related quality of life (HRQOL) than those with no knee injury history. It is unknown if this relationship is present in adolescent athletes. To determine the impact of knee injury history on HRQOL in adolescent athletes who were medically cleared for full participation. Cross-sectional. Athletic training clinics. A convenience sample of 183 adolescent athletes, who were medically cleared for full participation, were grouped by self-report of a previous knee injury: positive knee injury history [HIS] (n=36, age=15.7+1.35 years, height=168.0+11.9 cm; weight=71.8+11.9 kg) and no knee injury history [NO-HIS] (n=147, age=15.5+1.4 years, height=166.0+10.5 cm, weight=67.6+14.6 kg). Participants completed the pediatric version of the International Knee Documentation Committee form (Pedi-IKDC) and Pediatric Quality of Life Inventory (PedsQL) during their preparticipation examination. Generalized linear models were used to compare group differences for the total and subscale scores of the Pedi-IKDC and PedsQL. Main effects of injury group indicated that the HIS group reported significantly lower scores than the NO-HIS group for the Pedi-IKDC total score (p.05). Our findings suggest that, despite returning to full sport participation, adolescent athletes with a previous knee injury generally experience lower HRQOL than their peers with no knee injury history, specifically for knee-specific HRQOL, physical functioning, school functioning and social functioning. Our results are similar to previous findings reported in collegiate athletes and military cadets.

    Recurrent or chronic activity related knee pain is common in young athletes. Numerous intrinsic conditions affecting the knee can cause such pain. In addition, knee pain can be referred pain from low back, hip or pelvic pathology. The most common cause of knee pain in young athletes is patellofemoral pain syndrome, or more appropriately termed idiopathic anterior knee pain. Although, numerous anatomical and biomechanical factors have been postulated to contribute the knee pain in young athlet...

  15. Occupational ergonomics and injury prevention.

    1996-01-01

    Ergonomics is the study of people at work. The current focus is on the prevention of work-induced musculoskeletal injuries through the application of sound ergonomic principles. This chapter has briefly outlined ergonomics and its history, has described low back pain and upper extremity cumulative trauma disorders from an ergonomic perspective, and has discussed control and prevention approaches for a few scenarios. Ergonomic principles are based on a combination of science and engineering and a thorough understanding of human capabilities and limitations. When these principles are applied to the design of a job, task, process, or procedure, the incidence and severity of musculoskeletal injuries decrease. In many cases productivity and morale also improve. Workers are spared suffering, and employers are spared costs. It is hoped that this discussion will encourage more health, safety, and business professionals to learn about and apply ergonomics in their workplaces for the improvement of the worker, product, and business. Finally, many additional epidemiologic studies on the individual and joint effects of the CTD risk factors are needed. The knowledge gained from these studies will promote the more effective application of ergonomic principles to reduce worker suffering, improve products, and reduce costs.

    Full Text Available Abstract Background The Knee injury and Osteoarthritis Outcome Score (KOOS is an extension of the Western Ontario and McMaster Universities Osteoarthrtis Index (WOMAC, the most commonly used outcome instrument for assessment of patient-relevant treatment effects in osteoarthritis. KOOS was developed for younger and/or more active patients with knee injury and knee osteoarthritis and has in previous studies on these groups been the more responsive instrument compared to the WOMAC. Some patients eligible for total knee replacement have expectations of more demanding physical functions than required for daily living. This encouraged us to study the use of the Knee injury and Osteoarthritis Outcome Score (KOOS to assess the outcome of total knee replacement. Methods We studied the test-retest reliability, validity and responsiveness of the Swedish version LK 1.0 of the KOOS when used to prospectively evaluate the outcome of 105 patients (mean age 71.3, 66 women after total knee replacement. The follow-up rates at 6 and 12 months were 92% and 86%, respectively. Results The intraclass correlation coefficients were over 0.75 for all subscales indicating sufficient test-retest reliability. Bland-Altman plots confirmed this finding. Over 90% of the patients regarded improvement in the subscales Pain, Symptoms, Activities of Daily Living, and knee-related Quality of Life to be extremely or very important when deciding to have their knee operated on indicating good content validity. The correlations found in comparison to the SF-36 indicated the KOOS measured expected constructs. The most responsive subscale was knee-related Quality of Life. The effect sizes of the five KOOS subscales at 12 months ranged from 1.08 to 3.54 and for the WOMAC from 1.65 to 2.56. Conclusion The Knee injury and Osteoarthritis Outcome Score (KOOS is a valid, reliable, and responsive outcome measure in total joint replacement. In comparison to the WOMAC, the KOOS improved validity

    Injury prevention in Indigenous communities in Australia is a continuing national challenge, with Indigenous fatality rates due to injury three times higher than the general population. Suicide and transport are the leading causes of injury mortality, and assault, transport and falls the primary causes of injury morbidity. Addressing the complex range of injury problems in disadvantaged Indigenous communities requires considerable work in building or enhancing existing capacity of communities to address local safety issues. Poor data, lack of funding and absence of targeted programs are some of the issues that impede injury prevention activities. Traditional approaches to injury prevention can be used to highlight key areas of need, however adaptations are needed in keeping with Indigenous peoples' holistic approach to health, linked to land and linked to community in order to address the complex spiritual, emotional and social determinants of Indigenous injury.

    2016-01-01

    Participation in Australian football (AF) has traditionally been male dominated and current understanding of injury and priorities for prevention are based solely on reports of injuries in male players. There is evidence in other sports that indicates that injury types differ between males and females. With increasing participation in AF by females, it is important to consider their specific injury and prevention needs. This study aimed to provide a first injury profile from existing sources for female AF. Compilation of injury data from four prospectively recorded data sets relating to female AF: (1) hospital admissions in Victoria, 2008/09-13/14, n=500 injuries; (2) emergency department (ED) presentations in Victoria, 2008/09-2012/13, n=1,879 injuries; (3) insurance claims across Australia 2004-2013, n=522 injuries; (4) West Australian Women's Football League (WAWFL), 2014 season club data, n=49 injuries. Descriptive results are presented as injury frequencies, injury types and injury to body parts. Hospital admissions and ED presentations were dominated by upper limb injuries, representing 47% and 51% of all injuries, respectively, primarily to the wrist/hand at 32% and 40%. Most (65%) insurance claim injuries involved the lower limb, 27% of which were for knee ligament damage. A high proportion of concussions (33%) were reported in the club-collected data. The results provide the first compilation of existing data sets of women's AF injuries and highlight the need for a rigorous and systematic injury surveillance system to be instituted.

    Background: No studies have been reported on how strength, agility, and flexibility training reduce the occurrence of hamstring injuries in sprinters. Therefore, a program for preventing hamstring injury in these athletes has not been established. Purpose: To document the incidence of hamstring injuries during times when different prevention strategies were employed to see whether a particular prevention program reduced their occurrence. Study Design: Descriptive epidemiology study. Methods: The study subjects were a total of 613 collegiate male sprinters trained by the same coach over 24 seasons. Tow training was used throughout the research period as a normal sprint training method. The hamstring injury prevention program evolved over time. From 1988 to 1991 (period 1), prevention focused on strength training alone; from 1992 to 1999 (period 2), a combination of strength and agility training was used; and from 2000 to 2011 (period 3), the program incorporated strength, agility, and flexibility training. The incidence of hamstring injuries was compared for each of the 3 prevention strategies. Results: The incidence of hamstring injuries per athlete-seasons was 137.9 for period 1, 60.6 for period 2, and 6.7 for period 3. A significant difference was observed in the incidence of hamstring injury according to the different prevention programs (χ2(2) = 31.78, P hamstring injuries for period 1 was significantly greater than the expected value (P hamstring injuries in sprinters decreased as agility and flexibility were added to strength training.

    Prosthetic total knee replacements rarely dislocate. When dislocation does occur, it is usually in a posterior direction in association with a posterior stabilised, cruciate-sacrificing prosthesis. Neurovascular injury is unusual. In this report, we describe a case of anterior dislocation of a cruciate-retaining total knee replacement in a 67-year-old woman. The dislocation occurred in the absence of overt trauma and resulted in severe neurovascular injury. PMID:19686618

    The role of lower extremity (LE) muscle strength for predicting traumatic knee injury in youth athletes is largely unknown. The aim was to investigate the influence of LE muscle strength on traumatic knee injury in youth female and male athletes. 225 athletes (40% females) from sport senior high schools in Sweden were included in this case-control study. The athletes recorded any traumatic knee injury that had occurred during their high-school period in a web-based injury form. A one repetition maximum (1RM) barbell squat test was used to measure LE muscle strength. The 1RM was dichotomised to analyse 'weak' versus 'strong' athletes according to the median (weak median vs strong median ). 63 traumatic knee injuries, including 18 ACL injuries, were registered. The majority of injured female athletes were in the weak group compared with the strong group (p=0.0001). The odds of sustaining a traumatic knee injury and an ACL injury was 9.5 times higher and 7 times higher, respectively, in the weak median group compared with the strong median group in females (p ≤0.011). A relative 1RM squat ≤1.05 kg (105% of bodyweight) was established as the best cut-off value to distinguish high versus low risk of injury in female athletes. No strength-injury relationships were observed for the male athletes (p ≥0.348). Weaker LE muscle strength predicted traumatic knee injury in youth female athletes, but not in males. This suggests that LE muscle strength should be included in injury screening in youth female athletes.

A cross sectional descriptive design was employed to collect databy means of a questionnaire in 2010. Participants consisted of 254 netball playerswho participated in a netball tournament. Permission was obtained from all therelevant organizations and informed consent obtained from the participants. Thegeneral injury rate was 61.8% with an injury rate of 1.9 injuries per player forthe past season. The most commonly injured structures were the ankle 37.5 % andthe knee 28.6% with the most common mechanism of injury being landing, 19% and 29% respectively. Of those whosustained injuries, 86 (44% of the injured athletes’ sustained severe injuries, 31(16% sustained moderate injuriesand 78 (40% sustained mild injuries. 67% of players reported they were able to continue with the game and 33%received medical assistance losing game and training time. The most common form of management accessed wasphysiotherapy, which accounted for 31%. It is evident that the ankle and knee injury rates amongst South Africannetball players are high in comparison to other netball playing nations.

    To delineate the spectrum of knee injuries associated with sprains and tears of the distal iliotibial band (ITB). A retrospective review of 200 random MRI scans undertaken for acute knee trauma was performed. Scans were excluded if there was a history of injury over 4 weeks from the time of the scan, septic arthritis, inflammatory arthropathy, previous knee surgery, or significant artefact. In each scan, the ITB was scored as normal, minor sprain (grade 1), severe sprain (grade 2), and torn (grade 3). The menisci, ligaments, and tendons of each knee were also assessed. The mean age was 27.4 years (range, 9-69 years) and 71.5 % (n = 143) of the patients were male. The ITB was injured in 115 cases (57.5 %). The next most common soft tissue structure injured was the anterior cruciate ligament (ACL) in 53.5 % of cases (n = 107). Grade 1 ITB injury was seen in 90 of these 115 cases (45 %), grade 2 injury in 20 cases, and grade 3 injury in only five cases. There is a significant association between ITB injury and ACL rupture (p < 0.05), as well as acute patellar dislocation (p < 0.05). There were ten cases of significant posterolateral corner injury, and all were associated with ITB injury, including four ITB tears. Only two cases of isolated ITB injury were seen (1 %). ITB injury is common in acute knee trauma and is associated with significant internal derangement of the knee, especially cruciate ligament rupture, posterolateral corner injury, and patellar dislocation.

    2008-11-01

    Skiing and snowboarding are leading to a risk of injuries in children. Beginners and experienced have higher risk of injuries, however, the first have less severe injuries than the latest. Risk factors of injury are: ability and experience, binding adjustment, slope characteristics, speed, collisions with objects or jumping and risky behavior of the young skiers and snowboarders. Lower limb injuries are most common in skier, especially knee sprains, conversely snowboarders present more upper limb injuries, especially wrist fractures. The frequency of head injuries does not decrease while helmet use increases but severity decreases. Despite prevention and wearing protections, the frequency of trauma does not decrease significantly, which could be in relation with higher speed and increased risky behavior. Main prevention factors are safety knowledge and safety behavior, correct binding adjustment, and use of protections.

    2010-12-01

    Full Text Available This paper provided a brief summary of the current strategic goals, activities, and impacts of the NIOSH (National Institute for Occupational Safety and Health occupational injury research program. Three primary drivers (injury database, stakeholder input, and staff capacity were used to define NIOSH research focuses to maximize relevance and impact of the NIOSH injury-prevention-research program. Injury data, strategic goals, program activities, and research impacts were presented with a focus on prevention of four leading causes of workplace injury and death in the US: motor vehicle incidents, falls, workplace violence, and machine and industrial vehicle incidents. This paper showcased selected priority goals, activities, and impacts of the NIOSH injury prevention program. The NIOSH contribution to the overall decrease in fatalities and injuries is reinforced by decreases in specific goal areas. There were also many intermediate outcomes that are on a direct path to preventing injuries, such as new safety regulations and standards, safer technology and products, and improved worker safety training. The outcomes serve as an excellent foundation to stimulate further research and worldwide partnership to address global workplace injury problems.

    To describe the patterns of injury associated with injury to the popliteofibular ligament injury. A retrospective review was performed of 180 MRI scans undertaken for acute knee trauma. Scans were excluded if the time of injury was over 4 weeks from the time of the scan, or if there was a history of septic arthritis, inflammatory arthropathy, previous knee surgery, or significant artefact. An agreed criterion for assessing the structures of the posterolateral ligamentous complex was defined and in each scan, the popliteofibular ligament (PFL) was scored as normal or injured. The menisci, ligaments, and tendons of each knee were also assessed. The mean age was 25.7 years (range, 9-65 years) and 72.2 % (n = 130) patients were male. The PFL was injured in 36 cases (20 %). There is a significant association between PFL injury and ACL rupture (p = 0.0001), ITB injury (p = 0.0001), PCL injury (p = 0.0373), in addition to associations with injury to other posterolateral corner structures including the lateral collateral ligament (p = 0.0001), biceps femoris tendon (p = 0.0014), and popliteus tendon (p = 0.0014). Of our series of PFL injuries, nine cases (25 %) were associated with further injuries of posterolateral corner structures and in 27 cases (75 %) the PFL was the only posterolateral corner structure torn. PFL injury is not uncommon in acute knee trauma and is associated with significant internal derangement of the knee, especially anterior cruciate ligament rupture, ITB sprain, and injury to other structures within the posterolateral corner.

    To describe the leading mechanisms of hospitalised unintentional injury in Australian Aboriginal children and identify the injury mechanisms with the largest inequalities between Aboriginal and non-Aboriginal children. We used linked hospital and mortality data to construct a whole of population birth cohort including 1,124,717 children (1,088,645 non-Aboriginal and 35,749 Aboriginal) born in the state of New South Wales (NSW), Australia, between 1 July 2000 and 31 December 2012. Injury hospitalisation rates were calculated per person years at risk for injury mechanisms coded according to the ICD10-AM classification. The leading injury mechanisms in both groups of children were falls from playground equipment. For 66 of the 69 injury mechanisms studied, Aboriginal children had a higher rate of hospitalisation compared with non-Aboriginal children. The largest relative inequalities were observed for injuries due to exposure to fire and flame, and the largest absolute inequalities for injuries due to falls from playground equipment. Aboriginal children in NSW experience a significant higher burden of unintentional injury compared with their non-Aboriginal counterparts. Implications for Public Health: We suggest the implementation of targeted injury prevention measures aimed at injury mechanism and age groups identified in this study. © 2016 The Authors.

  18. Contribution of mechanical unloading to trabecular bone loss following non-invasive knee injury in mice.

    Development of osteoarthritis commonly involves degeneration of epiphyseal trabecular bone. In previous studies, we observed 30-44% loss of epiphyseal trabecular bone (BV/TV) from the distal femur within 1 week following non-invasive knee injury in mice. Mechanical unloading (disuse) may contribute to this bone loss; however, it is unclear to what extent the injured limb is unloaded following injury, and whether disuse can fully account for the observed magnitude of bone loss. In this study, we investigated the contribution of mechanical unloading to trabecular bone changes observed following non-invasive knee injury in mice (female C57BL/6N). We investigated changes in gait during treadmill walking, and changes in voluntary activity level using Open Field analysis at 4, 14, 28, and 42 days post-injury. We also quantified epiphyseal trabecular bone using μCT and weighed lower-limb muscles to quantify atrophy following knee injury in both ground control and hindlimb unloaded (HLU) mice. Gait analysis revealed a slightly altered stride pattern in the injured limb, with a decreased stance phase and increased swing phase. However, Open Field analysis revealed no differences in voluntary movement between injured and sham mice at any time point. Both knee injury and HLU resulted in comparable magnitudes of trabecular bone loss; however, HLU resulted in considerably more muscle loss than knee injury, suggesting another mechanism contributing to bone loss following injury. Altogether, these data suggest that mechanical unloading likely contributes to trabecular bone loss following non-invasive knee injury, but the magnitude of this bone loss cannot be fully explained by disuse. © 2016 Orthopaedic Research Society.

    OBJECTIVE: To prospectively examine the influence of hamstring-to-quadriceps (H:Q) ratio and structural abnormalities on the prevalence of overuse knee injuries among female collegiate athletes. DESIGN AND SETTING: We used chi-square 2 x 2 contingency tables and the Fischer exact test to examine associations among H:Q ratios, structural abnormalities, and overuse knee injuries. SUBJECTS: Fifty-three apparently healthy women (age = 19.4 +/- 1.3 years, height = 167.6 +/- 10.1 cm, mass = 65.0 +/- 10.0 kg) from National Collegiate Athletic Association Division I women's field hockey (n = 23), soccer (n = 20), and basketball teams (n = 10) volunteered. MEASUREMENTS: The H:Q ratio was determined from a preseason isokinetic test on a Biodex system at 60 degrees /s and 300 degrees /s. We measured athletes for genu recurvatum and Q-angles with a 14-in (35.56-cm) goniometer. Iliotibial band flexibility was assessed via the Ober test. RESULTS: Ten overuse knee injuries (iliotibial band friction syndromes = 5, patellar tendinitis = 3, patellofemoral syndrome = 1, pes anserine tendinitis = 1) occurred in 9 athletes. The H:Q ratio below the normal range at 300 degrees /s (P = 0.047) was associated with overuse knee injuries, as was the presence of genu recurvatum (P = 0.004). In addition, athletes possessing lower H:Q ratios at 300 degrees /s and genu recurvatum incurred more overuse knee injuries than athletes without these abnormalities (P = 0.001). CONCLUSIONS: The presence of genu recurvatum and an H: Q ratio below normal range was associated with an increased prevalence of overuse knee injuries among female collegiate athletes. Further investigation is needed to clarify which preseason screening procedures may identify collegiate athletes who are susceptible to overuse knee injuries.

    Efforts to reduce the burden of injury and violence require a workforce that is knowledgeable and skilled in prevention. However, there has been no systematic process to ensure that professionals possess the necessary competencies. To address this deficiency, we developed a set of core competencies for public health practitioners in injury and violence prevention programs. The core competencies address domains including public health significance, data, the design and implementation of prevention activities, evaluation, program management, communication, stimulating change, and continuing education. Specific learning objectives establish goals for training in each domain. The competencies assist in efforts to reduce the burden of injury and violence and can provide benchmarks against which to assess progress in professional capacity for injury and violence prevention.

    2013-11-01

    Endurance running has evolved over the course of millions of years and it is now one of the most popular sports today. However, the risk of stress injury in distance runners is high because of the repetitive ground impact forces exerted. These injuries are not only detrimental to the runner, but also place a burden on the medical community. Preventative measures are essential to decrease the risk of injury within the sport. Common running injuries include patellofemoral pain syndrome, tibial stress fractures, plantar fasciitis, and Achilles tendonitis. Barefoot running, as opposed to shod running (with shoes), has recently received significant attention in both the media and the market place for the potential to promote the healing process, increase performance, and decrease injury rates. However, there is controversy over the use of barefoot running to decrease the overall risk of injury secondary to individual differences in lower extremity alignment, gait patterns, and running biomechanics. While barefoot running may benefit certain types of individuals, differences in running stance and individual biomechanics may actually increase injury risk when transitioning to barefoot running. The purpose of this article is to review the currently available clinical evidence on barefoot running and its effectiveness for preventing injury in the runner. Based on a review of current literature, barefoot running is not a substantiated preventative running measure to reduce injury rates in runners. However, barefoot running utility should be assessed on an athlete-specific basis to determine whether barefoot running will be beneficial.

    Although injuries to the posterolateral corner of the knee were previously considered to be a rare condition, they have been shown to be present in almost 16% of all knee injuries and are responsible for sustained instability and failure of concomitant reconstructions if not properly recognized. Although also once considered to be the “dark side of the knee”, increased knowledge of the posterolateral corner anatomy and biomechanics has led to improved diagnostic ability with better understanding of physical and imaging examinations. The management of posterolateral corner injuries has also evolved and good outcomes have been reported after operative treatment following anatomical reconstruction principles. PMID:26401495

    Avulsion fractures and chronic avulsion injuries of the knee are common lesions in sports-related trauma, especially among adolescents. Magnetic resonance imaging may prove useful in detecting and characterizing such lesions, and has several advantages with regard to other imaging modalities. We review, illustrate, and discuss the MR imaging features of some of the more frequent avulsion fractures and chronic avulsion injuries of the knee, including avulsion fractures of the cruciate ligaments, avulsion fractures of lateral and medial stabilizers, avulsion fractures and chronic avulsion injuries of the extensor mechanism, and avulsive cortical irregularities of the distal femur. The role of MR imaging in evaluating such lesions is emphasized. (orig.)

    Instability of the proximal tibiofibular joint is a relatively uncommon condition when in isolation; however, instability of the proximal tibiofibular joint is far more frequent in those presenting with a severe multi-ligament injury of the knee. If this joint is left unstable, repair of a co-existent injury of the posterolateral corner may fail, regardless of the proficiency of the technique. We present two patients with disruption of the proximal tibiofibular joint, including the MRI appearance, who initially presented to our hospital for management of significant polytrauma, as well as multi-ligament injury of the ipsilateral knee.

    Youth and young adults who participate in sport have an increased risk of knee injury and subsequent osteoarthritis. Improved understanding of the relationship between structural and clinical outcomes postinjury could inform targeted osteoarthritis prevention interventions. This secondary analysis examines the association between MRI-defined osteoarthritis and self-reported and functional outcomes, 3-10 years following youth sport-related knee injury in comparison to healthy controls. Participants included a subsample (n=146) of the Alberta Youth Prevention of Early Osteoarthritis cohort: specifically, 73 individuals with 3-10 years history of sport-related intra-articular knee injury and 73 age-matched, sex-matched and sport-matched controls with completed MRI studies. Outcomes included: MRI-defined osteoarthritis, radiographic osteoarthritis, Knee Injury and Osteoarthritis Outcome Score, Intermittent and Constant Osteoarthritis Pain, knee extensor/flexor strength, triple-hop and Y-balance test. Descriptive statistics and univariate logistic regression were used to compare those with and without MRI-defined osteoarthritis. Associations between MRI-defined osteoarthritis and each outcome were assessed using multivariable linear regression considering the influence of injury history, sex, body mass index and time since injury. Participant median age was 23 years (range 15-27), and 63% were female. MRI-defined osteoarthritis varied by injury history, injury type and surgical history and was not isolated to participants with ACL and/or meniscal injuries. Those with a previous knee injury had 10-fold (95% CI 2.3 to 42.8) greater odds of MRI-defined osteoarthritis than uninjured participants. MRI-defined osteoarthritis was independently significantly associated with quality of life, but not symptoms, strength or function. MRI-detected structural changes 3-10 years following youth sport-related knee injury may not dictate clinical symptomatology, strength or function

    Floating knee injuries are frequently associated with other concomitant injuries to the ipsilateral limb or other parts of body of which injury to the ipsilateral knee ligaments carries significance for various reasons. A middle-aged man sustained a floating knee injury following RTA. DCS fixation by bridge plating technique for the distal femur and lateral buttress plating by MIPO technique for proximal tibia were planned and executed under spinal anesthesia with image intensifier. In addition, there were patellar tendon rupture along with avulsion of VMO from the medial border of patella and torn MPFL, which we have missed initially. To the best of our knowledge no similar case has been reported in English literature so far. We have reviewed the literature and proposed a different interpretation of Blake and McBride classification.

    Contralateral anterior cruciate ligament (CACL) injury after recovery from a first-time ACL rupture occurs at a high rate in young females; however, little is known about the risk factors associated with bilateral ACL trauma. The geometric characteristics of the contralateral knee at the time of the initial ACL injury are associated with risk of suffering a CACL injury in these female athletes. Case-control study; Level of evidence, 3. Sixty-two female athletes who suffered their first noncontact ACL injury while participating in sports at the high school or college level were identified, and geometry of the femoral notch, ACL, tibial spines, tibial subchondral bone, articular cartilage surfaces, and menisci of the contralateral, uninjured, knee was characterized in 3 dimensions. We were unable to contact 7 subjects and followed the remaining 55 until either a CACL injury or an ACL graft injury occurred or, if they were not injured, until the date of last contact (mean, 34 months after their first ACL injury). Cox regression was used to identify risk factors for CACL injury. Ten (18.2%) females suffered a CACL injury. Decreases of 1 SD in femoral intercondylar notch width (measured at its outlet and anterior attachment of the ACL) were associated with increases in the risk of suffering a CACL injury (hazard ratio = 1.88 and 2.05, respectively). Likewise, 1 SD decreases in medial-lateral width of the lateral tibial spine, height of the medial tibial spine, and thickness of the articular cartilage located at the posterior region of the medial tibial compartment were associated with 3.59-, 1.75-, and 2.15-fold increases in the risk of CACL injury, respectively. After ACL injury, subsequent injury to the CACL is influenced by geometry of the structures that surround the ACL (the femoral notch and tibial spines). This information can be used to identify individuals at increased risk for CACL trauma, who might benefit from targeted risk-reduction interventions.

  11. An Evidence-Based Framework for Strengthening Exercises to Prevent Hamstring Injury.

    Strength training is a valuable component of hamstring strain injury prevention programmes; however, in recent years a significant body of work has emerged to suggest that the acute responses and chronic adaptations to training with different exercises are heterogeneous. Unfortunately, these research findings do not appear to have uniformly influenced clinical guidelines for exercise selection in hamstring injury prevention or rehabilitation programmes. The purpose of this review was to provide the practitioner with an evidence-base from which to prescribe strengthening exercises to mitigate the risk of hamstring injury. Several studies have established that eccentric knee flexor conditioning reduces the risk of hamstring strain injury when compliance is adequate. The benefits of this type of training are likely to be at least partly mediated by increases in biceps femoris long head fascicle length and improvements in eccentric knee flexor strength. Therefore, selecting exercises with a proven benefit on these variables should form the basis of effective injury prevention protocols. In addition, a growing body of work suggests that the patterns of hamstring muscle activation diverge significantly between different exercises. Typically, relatively higher levels of biceps femoris long head and semimembranosus activity have been observed during hip extension-oriented movements, whereas preferential semitendinosus and biceps femoris short head activation have been reported during knee flexion-oriented movements. These findings may have implications for targeting specific muscles in injury prevention programmes. An evidence-based approach to strength training for the prevention of hamstring strain injury should consider the impact of exercise selection on muscle activation, and the effect of training interventions on hamstring muscle architecture, morphology and function. Most importantly, practitioners should consider the effect of a strength training programme on

    Each year 9,900 equestrians present at Accident and Emergency Departments, 40% of them 10-19 year old females. The most common horse-riding injuries are to the head, brain, neck and face, torso and extremities. Because of the relatively larger head, children more often fall on their head. Wearing a helmet gives considerable protection. Despite the common use of a helmet by horseback riders, serious head injury still occurs regularly. Further research into improvement of the protective function of the helmet is indicated. The current safety vest (body protector) does not significantly reduce the risk of torso injury. Improvement of its protective function is necessary. Injury to the lower extremities is caused when they become trapped in the stirrup in a fall from or with the horse. Safety stirrups and sturdy footwear are possible preventive measures. Investment in the quality and promotion of preventive measures could reduce the frequency and severity of equestrian injuries.

  13. Balance index score as a predictive factor for lower sports results or anterior cruciate ligament knee injuries in Croatian female athletes--preliminary study.

    Female athletes participating in high-risk sports suffer anterior cruciate ligament (ACL) knee injury at a 4- to 6-fold greater rate than do male athletes. ACL injuries result either from contact mechanisms or from certain unexplained non-contact mechanisms occurring during daily professional sports activities. The occurrence of non-contact injuries points to the existence of certain factors intrinsic to the knee that can lead to ACL rupture. When knee joint movement overcomes the static and the dynamic constraint systems, non-contact ACL injury may occur. Certain recent results suggest that balance and neuromuscular control play a central role in knee joint stability, protection and prevention of ACL injuries. The purpose of this study is to evaluate balance neuromuscular skills in healthy Croatian female athletes by measuring their balance index score, as well as to estimate a possible correlation between their balance index score and balance effectiveness. This study is conducted in an effort to reduce the risk of future injuries and thus prevent female athletes from withdrawing from sports prematurely. We analysed fifty-two female athletes in the high-risk sports of handball and volleyball, measuring for their static and dynamic balance index scores, using the Sport KAT 2000 testing system. This method may be used to monitor balance and coordination systems and may help to develop simpler measurements of neuromuscular control, which can be used to estimate risk predictors in athletes who withdraw from sports due to lower sports results or ruptured anterior cruciate ligament and to direct female athletes to more effective, targeted preventive interventions. The tested Croatian female athletes with lower sports results and ACL knee injury incurred after the testing were found to have a higher balance index score compared to healthy athletes. We therefore suggest that a higher balance index score can be used as an effective risk predictor for lower sports results

    To conduct a systematic review and meta-analysis to synthesize evidence regarding measurement properties of the Knee injury and Osteoarthritis Outcome Score (KOOS). A comprehensive literature search identified 37 eligible papers evaluating KOOS measurement properties in participants with knee injuries and/or osteoarthritis (OA). Methodological quality was evaluated using the COSMIN checklist. Where possible, meta-analysis of extracted data was conducted for all studies and stratified by age and knee condition; otherwise narrative synthesis was performed. KOOS has adequate internal consistency, test-retest reliability and construct validity in young and old adults with knee injuries and/or OA. The ADL subscale has better content validity for older patients and Sport/Rec for younger patients with knee injuries, while the Pain subscale is more relevant for painful knee conditions. The five-factor structure of the original KOOS is unclear. There is some evidence that the KOOS subscales demonstrate sufficient unidimensionality, but this requires confirmation. Although measurement error requires further evaluation, the minimal detectable change for KOOS subscales ranges from 14.3 to 19.6 for younger individuals, and ≥20 for older individuals. Evidence of responsiveness comes from larger effect sizes following surgical (especially total knee replacement) than non-surgical interventions. KOOS demonstrates adequate content validity, internal consistency, test-retest reliability, construct validity and responsiveness for age- and condition-relevant subscales. Structural validity, cross-cultural validity and measurement error require further evaluation, as well as construct validity of KOOS Physical function Short form. Suggested order of subscales for different knee conditions can be applied in hierarchical testing of endpoints in clinical trials. PROSPERO (CRD42011001603).

    Firearms are involved in the injury and death of a large number of children each year from both intentional and unintentional causes. Gun ownership in homes with children is common, and pediatricians should incorporate evidence-based means to discuss firearms and protect children from gun-related injuries and violence. Safe storage of guns, including unloaded guns locked and stored separately from ammunition, can decrease risks to children, and effective tools are available that pediatricians can use in clinical settings to help decrease children's access to firearms. Furthermore, several community-based interventions led by pediatricians have effectively reduced firearm-related injury risks to children. Educational programs that focus on children's behavior around guns have not proven effective. © American Academy of Pediatrics, 2015. All rights reserved.

    To investigate the association of cartilage degeneration with previous knee injuries not undergoing surgery, determined by morphologic and quantitative 3-T magnetic resonance imaging (MRI). We performed a nested cross-sectional study of right knee MRIs from participants in the Osteoarthritis Initiative (OAI) aged 45-79 with baseline Kellgren-Lawrence score of 0-2. Cases were 142 right knees of patients with self-reported history of injury limiting the ability to walk for at least 2 days. Controls were 426 right knees without history of injury, frequency-matched to cases on age, BMI, gender, KL scores and race (1:3 ratio). Cases and controls were compared using covariate-adjusted linear regression analysis, with the outcomes of region-specific T2 mean, laminar analysis and heterogeneity measured by texture analysis to investigate early cartilage matrix abnormalities and the Whole-Organ Magnetic Resonance Imaging Score (WORMS) to investigate morphologic knee lesions. Compared to control subjects, we found significantly higher mean T2 values in the injury [lateral tibia (28.10 ms vs. 29.11 ms, p = 0.001), medial tibia (29.70 ms vs. 30.40 ms, p = 0.014) and global knee cartilage (32.73 ms vs. 33.29 ms, p = 0.005)]. Injury subjects also had more heterogeneous cartilage as measured by GLCM texture contrast, variance and entropy (p < 0.05 in 14 out of 18 texture parameters). WORMS gradings were not significantly different between the two groups (p > 0.05). A history of knee injury not treated surgically is associated with higher and more heterogeneous T2 values, but not with morphologic knee abnormalities. Our findings suggest that significant, conservatively treated knee injuries are associated with permanent cartilage matrix abnormalities. (orig.)

  3. Common Running Overuse Injuries and Prevention

    Directory of Open Access Journals (Sweden)

    Žiga Kozinc

    2017-09-01

    Full Text Available Runners are particularly prone to developing overuse injuries. The most common running-related injuries include medial tibial stress syndrome, Achilles tendinopathy, plantar fasciitis, patellar tendinopathy, iliotibial band syndrome, tibial stress fractures, and patellofemoral pain syndrome. Two of the most significant risk factors appear to be injury history and weekly distance. Several trials have successfully identified biomechanical risk factors for specific injuries, with increased ground reaction forces, excessive foot pronation, hip internal rotation and hip adduction during stance phase being mentioned most often. However, evidence on interventions for lowering injury risk is limited, especially regarding exercise-based interventions. Biofeedback training for lowering ground reaction forces is one of the few methods proven to be effective. It seems that the best way to approach running injury prevention is through individualized treatment. Each athlete should be assessed separately and scanned for risk factors, which should be then addressed with specific exercises. This review provides an overview of most common running-related injuries, with a particular focus on risk factors, and emphasizes the problems encountered in preventing running-related injuries.

Objective: To analyze the effectiveness of current lower extremity injury prevention programs in basketball athletes, focusing on injury rates of (1) general lower extremity injuries, (2) ankle sprains, and (3) anterior cruciate ligament (ACL) tears. Data Sources: PubMed, MEDLINE, CINAHL, SPORTDiscus, and the Cochrane Register of Controlled Trials were searched in January 2015. Study Selection: Studies were included if they were randomized controlled or prospective cohort trials, contained a population of competitive basketball athletes, and reported lower extremity injury incidence rates specific to basketball players. In total, 426 individual studies were identified. Of these, 9 met the inclusion criteria. One other study was found during a hand search of the literature, resulting in 10 total studies included in this meta-analysis. Study Design: Systematic review and meta-analysis. Level of Evidence: Level 2. Data Extraction: Details of the intervention (eg, neuromuscular vs external support), size of control and intervention groups, and number of injuries in each group were extracted from each study. Injury data were classified into 3 groups based on the anatomic diagnosis reported (general lower extremity injury, ankle sprain, ACL rupture). Results: Meta-analyses were performed independently for each injury classification. Results indicate that prophylactic programs significantly reduced the incidence of general lower extremity injuries (odds ratio [OR], 0.69; 95% CI, 0.57-0.85; P basketball athletes. Conclusion: In basketball players, prophylactic programs may be effective in reducing the risk of general lower extremity injuries and ankle sprains, yet not ACL injuries. PMID:26502412

  5. Anterior cruciate ligament injuries in soccer: Loading mechanisms, risk factors, and prevention programs

    Full Text Available Anterior cruciate ligament (ACL injuries are common in soccer. Understanding ACL loading mechanisms and risk factors for ACL injury is critical for designing effective prevention programs. The purpose of this review is to summarize the relevant literature on ACL loading mechanisms, ACL injury risk factors, and current ACL injury prevention programs for soccer players. Literature has shown that tibial anterior translation due to shear force at the proximal end of tibia is the primary ACL loading mechanism. No evidence has been found showing that knee valgus moment is the primary ACL loading mechanism. ACL loading mechanisms are largely ignored in previous studies on risk factors for ACL injury. Identified risk factors have little connections to ACL loading mechanisms. The results of studies on ACL injury prevention programs for soccer players are inconsistent. Current ACL injury prevention programs for soccer players are clinically ineffective due to low compliance. Future studies are urgently needed to identify risk factors for ACL injury in soccer that are connected to ACL loading mechanisms and have cause-and-effect relationships with injury rate, and to develop new prevention programs to improve compliance.

    Youth have very high participation and injury rates in sport. Sport is the leading cause of injury in youth. Sport injury reduces future participation in physical activity which adversely affects future health. Sport injury may lead to overweight/obesity and post-traumatic osteoarthritis. The objective of the systematic review and meta-analysis was to evaluate the efficacy of injury prevention neuromuscular training strategies in youth sport. Three electronic databases were systematically searched up to September 2014. Studies selected met the following criteria: original data; analytic prospective design; investigated a neuromuscular training prevention strategy intervention(s) and included outcomes for injury sustained during sport participation. Two authors assessed the quality of evidence using Downs and Black (DB) criteria. Meta-analyses including randomised controlled trials only (RCTs) to ensure study design homogeneity were completed for lower extremity and knee injury outcomes. Of 2504 potentially relevant studies, 25 were included. Meta-analysis revealed a combined preventative effect of neuromuscular training in reducing the risk of lower extremity injury (incidence rate ratio: IRR=0.64 (95% CI 0.49 to 0.84)). Though not statistically significant, the point estimate suggests a protective effect of such programmes in reducing the risk of knee injury (IRR=0.74 (95% CI 0.51 to 1.07)). There is evidence for the effectiveness of neuromuscular training strategies in the reduction of injury in numerous team sports. Lack of uptake and ongoing maintenance of such programmes is an ongoing concern. A focus on implementation is critical to influence knowledge, behaviour change and sustainability of evidence informed injury prevention practice. Published by the BMJ Publishing Group Limited.

    There is broad consensus that good outcome measures are needed to distinguish interventions that are effective from those that are not. This task requires standardized, patient-centered measures that can be administered at a low cost. We developed a questionnaire to assess short- and long......-term patient-relevant outcomes following knee injury, based on the WOMAC Osteoarthritis Index, a literature review, an expert panel, and a pilot study. The Knee injury and Osteoarthritis Outcome Score (KOOS) is self-administered and assesses five outcomes: pain, symptoms, activities of daily living, sport...

    1989-06-01

    In brief: Rugby is a popular, strenuous contact sport that demands almost continuous action by the players. Players, coaches, and physicians must be aware of the potential for and types of injuries that occur during matches and of ways to avoid, or at least reduce, this number and severity. Minor and moderate injuries are more frequent than severe injuries, but all must be regarded seriously. Concussions, although relatively rare, can have serious consequences, and cervical spine injuries can be catastrophic. Player fitness and conditioning and a pregame warm-up are all essential for preventing injuries. Equally important are coaching, adherence to the rules of the game, and avoidance of dangerous play. If these measures are practiced consistently, rugby will be safer.

    The purpose of the study was to evaluate the relationship between the location of bone signal abnormality and associated injury, as seen on MR, in patients with acute knee joint injury. Materials and Methods: Thirty-six patients with acute knee injury and bone signal abnormalities on MR were included in this study. The femur and tibia were each divided into six compartments, namely the anteromedial, medial, posteromedial,anterolateral, lateral, and posterolateral ; these were obtained in each knee joint. We evaluated the location of bone signal abnormality and the corresponding arthroscopic or operative findings of injury to ligaments and menisci. Cases with signal abnormalities involving more than three compartments were excluded. Results : Bone signal abnormalities were demonstrated in 51 compartments. Most(84%, 43/51) were noted in the lateral half of the knee joint, the most common location being the tibio- posterolateral compartment(13/51). The femoro-lateral(11/51) and tibio- anterolateral compartment(8/51) were the next most common locations. All cases(13/13)with bone signal abnormality in the tibio- posterolateral compartment had tears at the anterior cruciate ligament,while 9 of 11 cases(81%) with abnormality in the femoro- lateral compartment had tears at the anterior cruciate ligament. Six of eight cases(75%) with signal abnormality in the tibio- anterolateral compartment had tears at the posterior cruciate ligament ; 31 of 43 cases (72%) with abnormality in the lateral half of the knee joint had tears at the medial collateral ligament. Six of eight cases(75%) with signal abnormality in the medial half of the knee joint had tears at the medial meniscus, but no lateral meniscal tear was found. Among patients with signal abnormality in the lateral half of the knee joint, the tear was lateral meniscal in nine of 43 cases(21%) and medial meniscal in six of 43(14%). Conclusion : The location of bone signal abnormality, as seen on knee MR, inpatients with

    Post-traumatic osteoarthritis (PTOA) commonly affects the knee joint. Although the risk of PTOA substantially increases post-joint injury, there is little research examining PTOA outcomes early in the period between joint injury and disease onset. Improved understanding of this interval would inform secondary prevention strategies aimed at preventing and/or delaying PTOA progression. This study examines the association between sport-related knee injury and outcomes related to development of PTOA, 3-10 years post-injury. This preliminary analysis of the first year of a historical cohort study includes 100 (15-26 years) individuals. Fifty with a sport-related intra-articular knee injury sustained 3-10 years previously and 50 uninjured age, sex and sport matched controls. The primary outcome was the 'Symptoms' sub-scale of the Knee Osteoarthritis and Injury Outcome Score (KOOS). Secondary outcomes included; the remaining KOOS subscales, body mass index (BMI), hip abductor/adductor and knee extensor/flexor strength, estimated aerobic capacity (VO2max) and performance scores on three dynamic balance tests. Descriptive statistics (mean within-pair difference; 95% Confidence interval (CI) and conditional odds ratio (OR, 95% CI; BMI) were used to compare study groups. Injured participants demonstrated poorer KOOS outcomes [symptoms -9.4 (-13.6, -5.2), pain -4.0 (-6.8, -1.2), quality-of-life -8.0 (-11.0, -5.1), daily living -3.0 (-5.0, -1.1) and sport/recreation -6.9 (-9.9, -3.8)], were 3.75 times (95% CI 1.24, 11.3) more likely to be overweight/obese and had lower triple single leg hop scores compared to controls. No significant group differences existed for remaining balance scores, estimated VO2max, hip or knee strength ratios or side-to-side difference in hip abductor/adductor or quadricep/hamstring strength. This study provides preliminary evidence that youth/young adults following sport-related knee injury report more symptoms and poorer function, and are at

    Female athletes have a higher risk of anterior cruciate ligament injury than their male counterparts who play at similar levels in sports involving pivoting and landing. The competitive female basketball players who participated in a sports injury prevention training program would show better muscle strength and flexibility and improved biomechanical properties associated with anterior cruciate ligament injury than during the pretraining period and than posttraining parameters in a control group. Controlled laboratory study. A total of 22 high school female basketball players were recruited and randomly divided into 2 groups (the experimental group and the control group, 11 participants each). The experimental group was instructed in the 6 parts of the sports injury prevention training program and performed it during the first 20 minutes of team practice for the next 8 weeks, while the control group performed their regular training program. Both groups were tested with a rebound-jump task before and after the 8-week period. A total of 21 reflective markers were placed in preassigned positions. In this controlled laboratory study, a 2-way analysis of variance (2 x 2) experimental design was used for the statistical analysis (P training effects on all strength parameters (P = .004 to .043) and on knee flexion, which reflects increased flexibility (P = .022). The experimental group showed higher knee flexion angles (P = .024), greater interknee distances (P = .004), lower hamstring-quadriceps ratios (P = .023), and lower maximum knee extension torques (P = .043) after training. In the control group, no statistical differences were observed between pretraining and posttraining findings (P = .084 to .873). At pretraining, no significant differences were observed between the 2 groups for any parameter (P = .067 to .784). However, a comparison of the 2 groups after training revealed that the experimental group had significantly higher knee flexion angles (P = .023

    Peroneal nerve palsy is a frequent and potentially disabling complication of multiligament knee dislocation, but little information exists on the degree to which patients recover motor or sensory function after this injury, and whether having this nerve injury--with or without complete recovery--is a predictor of inferior patient-reported outcome scores. The purposes of this study were to (1) report on motor and sensory recovery as well as patient-reported outcomes scores of patients with peroneal nerve injury from multiligament knee dislocation; (2) compare those endpoints between patients who had partial versus complete nerve injuries; and (3) compare patient-reported outcomes among patients who sustained peroneal nerve injuries after knee dislocation with a matched cohort of multiligament knee injuries without nerve injury. Thirty-two patients were identified, but five did not have 2-year followup and are excluded (16% lost to followup). Twenty-seven patients (24 male, three female) with peroneal nerve injury underwent multiligament knee reconstruction and were followed for 6.3 years (range, 2-18 years). Motor grades were assessed by examination and outcomes by International Knee Documentation Committee (IKDC) and Lysholm scores. Retrospectively, patients were divided into complete (n = 9) and partial nerve palsy (n = 18). Treatment for complete nerve palsy included an ankle-foot orthosis for all patients, nonoperative (one), neurolysis (two), tendon transfer (three), nerve transfer (one), and combined nerve/tendon transfer (one). Treatment for partial nerve palsy included nonoperative (12), neurolysis (four), nerve transfer (one), and combined nerve/tendon transfer (one). Furthermore, patients without nerve injury were matched by Schenck classification, age, and sex. Data were analyzed using univariate and multivariate models. Overall, 18 patients (69%) regained antigravity ankle dorsiflexion after treatment (three complete nerve palsy [38%] versus 15 partial

    Subchondral insufficiency fractures are non-traumatic fractures that occur immediately below the cartilage of a joint. Although low bone density may be present concurrently, it is not the underlying cause of subchondral insufficiency fractures in the majority of patients. Patients with subchondral insufficiency fracture characteristically have unremarkable plain radiographs, while MRI examination may reveal extensive bone marrow oedema and subchondral bone collapse. This article presents a 51-year-old postmenopausal woman, a physician, who had subchondral insufficiency fractures of the knee associated with prolonged standing during clinical work. She was treated with partial weight bearing on crutches until 14 months after the injury, viscosupplementation at 4 months to treat osteoarthritis and teriparatide treatment to improve bone healing at 7 months. By 26 months after the injury, she tolerated independent walking with a fabric knee support but still experienced mild posterolateral knee pain and numbness on prolonged standing. 2015 BMJ Publishing Group Ltd.

In previous studies, we observed 30–44% loss of epiphyseal trabecular bone (BV/TV) from the distal femur within one week following non-invasive knee injury in mice. Mechanical unloading (disuse) may contribute to this bone loss, however it is unclear to what extent the injured limb is unloaded following injury, and whether disuse can fully account for the observed magnitude of bone loss.

    Both acute and overuse injuries are common among recreational volleyball players, especially finger/wrist, ankle, shoulder and knee injuries. Consequently, an intervention ('VolleyVeilig') was developed to prevent or reduce the occurrence of finger/wrist, shoulder, knee and ankle injuries among recreational volleyball players. This article describes the design of a study evaluating the effectiveness of the developed intervention on the one-season occurrence of finger/wrist, shoulder, knee and ankle injuries among recreational adult volleyball players. A randomized prospective controlled trial with a follow-up period of one volleyball season will be conducted. Participants will be healthy recreational adult volleyball players (18 years of age or older) practicing volleyball (training and/or match) at least twice a week. The intervention ('VolleyVeilig') consists of a warm-up program based on more than 50 distinct exercises (with different variations and levels). The effect of the intervention programme on the occurrence of injuries will be compared to volleyball as usual. Outcome measures will be incidence of acute injury (expressed as number of injuries per 1000 h of play) and prevalence of overuse injuries (expressed as percentage). This study will be one of the first randomized prospective controlled trials evaluating the effectiveness of an intervention on the occurrence of both acute and overuse injuries among recreational adult volleyball players. Outcome of this study could possibly lead to the nationwide implementation of the intervention in all volleyball clubs in The Netherlands, ultimately resulting in less injuries.

    The incidence of knee ligament injury is increasing and represents a significant cost to healthcare providers. Current interventions include tissue grafts, suture repair and non-surgical management. These techniques have demonstrated good patient outcomes but have been associated graft rejection, infection, long term immobilization and reduced joint function. The limitations of traditional management strategies have prompted research into tissue engineering of knee ligaments. This paper aims to evaluate whether tissue engineering of knee ligaments offers a viable alternative in the clinical management of knee ligament injuries. A search of existing literature was performed using OVID Medline, Embase, AMED, PubMed and Google Scholar, and a manual review of citations identified within these papers. Silk, polymer and extracellular matrix based scaffolds can all improve graft healing and collagen production. Fibroblasts and stem cells demonstrate compatibility with scaffolds, and have been shown to increase organized collagen production. These effects can be augmented using growth factors and extracellular matrix derivatives. Animal studies have shown tissue engineered ligaments can provide the biomechanical characteristics required for effective treatment of knee ligament injuries. There is a growing clinical demand for a tissue engineered alternative to traditional management strategies. Currently, there is limited consensus regarding material selection for use in tissue engineered ligaments. Further research is required to optimize tissue engineered ligament production before clinical application. Controlled clinical trials comparing the use of tissue engineered ligaments and traditional management in patients with knee ligament injury could determine whether they can provide a cost-effective alternative.

    2009-12-01

    While gender-based differences in knee joint anatomies/laxities are well documented, the potential for them to precipitate gender-dimorphic ACL loading and resultant injury risk has not been considered. To this end, we generated gender-specific models of ACL strain as a function of any six degrees of freedom (6DOF) knee joint load state via a combined cadaveric and analytical approach. Continuously varying joint forces and torques were applied to five male and five female cadaveric specimens and recorded along with synchronous knee flexion and ACL strain data. All data (approximately 10,000 samples) were submitted to specimen-specific regression analyses, affording ACL strain predictions as a function of the combined 6 DOF knee loads. Following individual model verifications, generalized gender-specific models were generated and subjected to 6 DOF external load scenarios consistent with both a clinical examination and a dynamic sports maneuver. The ensuing model-based strain predictions were subsequently examined for gender-based discrepancies. Male and female specimen-specific models predicted ACL strain within 0.51%+/-0.10% and 0.52%+/-0.07% of the measured data respectively, and explained more than 75% of the associated variance in each case. Predicted female ACL strains were also significantly larger than respective male values for both simulated 6 DOF load scenarios. Outcomes suggest that the female ACL will rupture in response to comparatively smaller external load applications. Future work must address the underlying anatomical/laxity contributions to knee joint mechanical and resultant ACL loading, ultimately affording prevention strategies that may cater to individual joint vulnerabilities.

    The purpose of this study was to determine the epidemiology and history of knee injury and its impact on activity limitation among football premier league professional referees in Iran. This was a descriptive study. 59 Football Premier League professional referees participated in the study. The knee injury related information such as injury history and mechanism was recorded. Injury related symptoms and their impacts on the activity limitation, ability to perform activities of daily living as well participation in sports and recreational activities was obtained through the Knee Outcome Survey (KOS). The results indicated that 31 out of 59 participants reported the history of knee injury. In addition, 18.6%, 22.4% and 81% of the referees reported that they had been injured during the last 6 months of the last year, and at some point in their refereeing careers, respectively. Results further indicated that 48.8% of the injuries occurred in the non-dominant leg and they occurred more frequently during training sessions (52%). Furthermore, the value of KOS was 85 ± 13 for Activities of Daily Living subscale and 90 ± 9 for Sports and Recreational Activities subscale of the KOS. Knee injury was quite common among the Football Premier League professional referees. It was also indicated that the injuries occurred mainly due to insufficient physical fitness. Therefore, it is suggested that football referees undergo the proper warm-up program to avoid knee injury.

    2010-10-01

    Full Text Available The estimated annual burn incidence in India is approximately 6-7 million per year. The high incidence is attributed to illiteracy, poverty and low level safety consciousness in the population. The situation becomes further grim due to the absence of organized burn care at primary and secondary health care level. But the silver lining is that 90% of burn injuries are preventable. An initiative at national level is need of the hour to reduce incidence so as to galvanize the available resources for more effective and standardized treatment delivery. The National Programme for Prevention of Burn Injuries is the endeavor in this line. The goal of National programme for prevention of burn injuries (NPPBI would be to ensure prevention and capacity building of infrastructure and manpower at all levels of health care delivery system in order to reduce incidence, provide timely and adequate treatment to burn patients to reduce mortality, complications and provide effective rehabilitation to the survivors. Another objective of the programme will be to establish a central burn registry. The programme will be launched in the current Five Year Plan in Medical colleges and their adjoining district hospitals in few states. Subsequently, in the next five year plan it will be rolled out in all the medical colleges and districts hospitals of the country so that burn care is provided as close to the site of accident as possible and patients need not to travel to big cities for burn care. The programme would essentially have three components i.e. Preventive programme, Burn injury management programme and Burn injury rehabilitation programme.

    The objective of this study is to evaluate significant contributing factors affecting the functional prognosis of floating knee injuries using multivariate analysis. A total of 68 floating knee injuries (67 patients) were treated at Kitasato University Hospital from 1986 to 1999. Both the femoral fractures and the tibial fractures were managed surgically by various methods. The functional results of these injuries were evaluated using the grading system of Karlström and Olerud. Follow-up periods ranged from 2 to 19 years (mean 50.2 months) after the original injury. We defined satisfactory (S) outcomes as those cases with excellent or good results and unsatisfactory (US) outcomes as those cases with acceptable or poor results. Logistic regression analysis was used as a multivariate analysis, and the dependent variables were defined as a satisfactory outcome or as an unsatisfactory outcome. The explanatory variables were predicting factors influencing the functional outcome such as age at trauma, gender, severity of soft-tissue injury in the femur and the tibia, AO fracture grade in the femur and the tibia, Fraser type (type I or type II), Injury Severity Score (ISS), and fixation time after injury (less than 1 week or more than 1 week) in the femur and the tibia. The final functional results were as follows: 25 cases had excellent results, 15 cases good results, 16 cases acceptable results, and 12 cases poor results. The predictive logistic regression equation was as follows: Log 1-p/p = 3.12-1.52 x Fraser type - 1.65 x severity of soft-tissue injury in the tibia - 1.31 x fixation time after injury in the tibia - 0.821 x AO fracture grade in the tibia + 1.025 x fixation time after injury in the femur - 0.687 x AO fracture grade in the femur ( p=0.01). Among the variables, Fraser type and the severity of soft-tissue injury in the tibia were significantly related to the final result. The multivariate analysis showed that both the involvement of the knee joint and

    In patients with chronic knee pain, the diagnostic performance of 99m Tc-MDP knee SPECT for internal derangement of knee is deteriorated due to degenerative changes. In this study, we tried to establish diagnostic criteria to differentiate medial meniscal injury (MMI) from degenerative change (DC) when the uptake in increased in medial compartment. A total of 49 knee SPECT of the patients with chronic(more than 3 months) knee pain, which showed increased 99m Tc-MDP uptake in the medial compartment, were included in this study. The diagnosis was confirmed by arthroscopy. On knee SPECT, 3 diagnosic criteria for MMI were investigated. In Criterion, I, MMI was diagnosed when crescentic uptake was observed in the medial tibial plateau. In Criterion II, crescentic uptake was further classified into anterior, mid, posterior, and diffuse patterns, according to the location of maximal uptake; and only crescentic mid, posterior, and diffuse patterns were diagnosed as MMI. In Criterion III, MMI was diagnosed when medial tibial plateau showed higher activity then medial femoral condyle. The diagnostic performance of the 3 criteria was compared. The sensitivity and specificity were 93% and 14% in Criterion I, 89% and 38% in Criterion II, and 75% and 67% in Criterion III, respectively. Criterion III had significantly improve diagnostic performance, especially, specificity. In this study, we established a practical diagnostic criterion to differentiate MMI from DC on knee SPECT. The result is helpful to improve the diagnostic value of knee SPECT as a screening test for chronic knee pain

    This study aimed to provide a comprehensive strength-based physiological profile of women's NCAA Division I basketball and gymnastic athletes; and to make sport-specific comparisons for various strength characteristics of the knee flexor and extensor muscles. A focus on antagonist muscle balance (hamstrings-to-quadriceps ratios, H:Q) was used to elucidate vulnerabilities in these at-risk female athletes. Fourteen NCAA Division I women's basketball and 13 gymnastics athletes performed strength testing of the knee extensors and flexors. Outcome measures included absolute and relative (body mass normalised) peak torque (PT), rate of torque development at 50, 100, 200 ms (RTD50 etc.) and H:Q ratios of all variables. The basketball athletes had greater absolute strength for all variables except for isokinetic PT at 240°s -1 and isometric RTD50 for the knee extensors. Gymnasts showed ~20% weaker body mass relative concentric PT for the knee flexors at 60 and 120°·s -1 , and decreased conventional H:Q ratios at 60 and 240°·s -1 (~15%). These findings suggest that collegiate level gymnastics athletes may be prone to increased ACL injury risk due to deficient knee flexor strength and H:Q strength imbalance. Coaches may use these findings when implementing injury prevention screening and/or for individualised strength training programming centered around an athletes strength-related deficits.

    Objective: To evaluate the correlation between bone contusion and ligament, meniscus injury of knee joint with MR imaging. Methods: Thirty-five patients with acute trauma of knee joint were studied retrospectively. All eases showed negative on X-ray and bone cont, -sion on MR imaging. Results: in all patients, ligament and meniscus injury were seen in 25 cases (71%), incorporate anterior cruciate ligament injury in 12 cases, posterior cruciate ligament in 6, tibial collateral ligament in 8 cases, fibular collateral ligament in 6 cases, medial meniscus tear in 4 cases, lateral meniscus tear in 5 cases, and hydrops in 29 cases. There were only 3 patients with ligament or meniscus injury but no bone contusion during the same period. Conclusion: It is necessary to check by MR for the patients with acute trauma of knee joint, who have clinical symptom such as ache, swelling, move un-freely showing bone contusion on MR Imaging but without any abnormality on X-ray in order to avoid failure in diagnosing injury of ligament and meniscus.

    The Knee Injury and Osteoarthritis Outcome Score (KOOS) is a commonly used knee assessment and outcome tool in both clinical work and research. However, it has not been formally translated and validated in Finnish. The purpose of this study was to translate and culturally adapt the KOOS questionnaire into Finnish and to determine its validity and reliability among Finnish middle-aged patients with knee injuries. KOOS was translated and culturally adapted from English into Finnish. Subsequently, 59 patients with knee injuries completed the Finnish version of KOOS, Western Ontario and McMaster Osteoarthritis Index (WOMAC), Short-Form 36 Health Survey (SF-36) and Numeric Pain Rating Scale (Pain-NRS). The same KOOS questionnaire was re-administered 2 weeks later. Psychometric assessment of the Finnish KOOS was performed by testing its construct validity and reliability by using internal consistency, test-retest reliability and measurement error. The floor and ceiling effects were also examined. The cross-cultural adaptation revealed only minor cultural differences and was well received by the patients. For construct validity, high to moderate Spearman's Correlation Coefficients were found between the KOOS subscales and the WOMAC, SF-36, and Pain-NRS subscales. The Cronbach's alpha was from 0.79 to 0.96 for all subscales indicating acceptable internal consistency. The test-retest reliability was good to excellent, with Intraclass Correlation Coefficients ranging from 0.73 to 0.86 for all KOOS subscales. The minimal detectable change ranged from 17 to 34 on an individual level and from 2 to 4 on a group level. No floor or ceiling effects were observed. This study yielded an appropriately translated and culturally adapted Finnish version of KOOS which demonstrated good validity and reliability. Our data indicate that the Finnish version of KOOS is suitable for assessment of the knee status of Finnish patients with different knee complaints. Further studies are needed to

    Full Text Available The articular cartilage is prone to suffer lesions of different etiology, being the articular cartilage lesions of the knee the most common. Although most conventional treatments reduce symptoms they lead to the production of fibrocartilage, which has different characteristics than the hyaline cartilage of the joint. There are few therapeutic approaches that promote the replacement of damaged tissue by functional hyaline cartilage. Among them are the so-called advanced therapies, which use cells and tissue engineering products to promote cartilage regeneration. Most of them are based on scaffolds made of different biomaterials, which seeded or not with endogenous or exogenous cells, can be used as cartilage artificial replacement to improve joint function. This paper reviews some therapeutic approaches focused on the regeneration of articular cartilage of the knee and the biomaterials used to develop scaffolds for cell therapy and tissue engineering of cartilage.

    evidence that a longer, more gradual increase in training reduces injuries in novice runners (one trial; 486 participants; RR 1.02, 95% CI 0.72 to 1.45). There was some evidence from a poor quality trial that additional training resulted in a significant increase in the number of naval recruits with shin splints (one trial; 1670 participants; RR 2.02, 95% CI 1.11 to 3.70). There was limited evidence that injuries were less frequent in prisoners when running duration (one trial; 69 participants; RR 0.41, 95% CI 0.21 to 0.79) or frequency (one trial; 58 participants; RR 0.19, 95% CI 0.06 to 0.66) were reduced.Patellofemoral braces appear to be effective for preventing anterior knee pain (two trials; 227 participants; RR 0.41, 95% CI 0.24 to 0.67).Custom-made biomechanical insoles may be more effective than no insoles for reducing shin splints (medial tibial stress syndrome) in military recruits (one trial; 146 participants; RR 0.24, 95% CI 0.08 to 0.69).We found no evidence in military recruits that wearing running shoes based on foot shape, rather than standard running shoes, significantly reduced rate of running injuries (2 trials; 5795 participants; Rate Ratio 1.03, 95% CI 0.93 to 1.14). Overall, the evidence base for the effectiveness of interventions to reduce soft-tissue injury after intensive running is very weak, with few trials at low risk of bias. More well-designed and reported RCTs are needed that test interventions in recreational and competitive runners.

    Forty million individuals participate in organized softball leagues each year in the United States. Eighteen million additional student athletes and young adults also participate in organized baseball league play. In addition to being two of the most popular team sports in the United States, they also are responsible for a significant percentage of sports-related injuries that are sustained in the United States. Fortunately, numerous interventions independently have been shown to be effective at reducing the injury scenario, which has grown to be of epidemic proportion. Interventions such as break-away bases, batting helmets, face shields on helmets, lighter mass baseballs, and teaching and reiteration of the fundamentals of softball and baseball all have been effective in preventing millions of injuries and billions of dollars in healthcare costs each year in the United States.

    Peden, Margie

    2005-06-01

    Worldwide, nearly 1.2 million people are killed in road traffic crashes every year and 20 million to 50 million more are injured or disabled. These injuries account for 2.1% of global mortality and 2.6% of all disability-adjusted life years (DALYs) lost. Low- and middle-income countries account for about 85% of the deaths and 90% of the DALYs lost annually. Without appropriate action, by 2020, road traffic injuries are predicted to be the third leading contributor to the global burden of disease. The economic cost of road traffic crashes is enormous. Globally it is estimated that US$518 billion is spent on road traffic crashes with low- and middle-income countries accounting for US$65 billion--more than these countries receive in development assistance. But these costs are just the tip of the iceberg. For everyone killed, injured or disabled by a road traffic crash there are countless others deeply affected. Many families are driven into poverty by the expenses of prolonged medical care, loss of a family breadwinner or the added burden of caring for the disabled. There is an urgent need for global collaboration on road traffic injury prevention. Since 2000, WHO has stepped up its response to the road safety crisis by firstly developing a 5-year strategy for road traffic injury prevention and following this by dedicating World Health Day 2004 to road safety and launching the WHO/World Bank World Report on Road Traffic Injury Prevention at the global World Health Day event in Paris, France. This short article highlights the main messages from the World Report and the six recommendations for action on road safety at a national and international level. It goes on to briefly discuss other international achievements since World Health Day and calls for countries to take up the challenge of implementing the recommendations of the World Report.

    Objective: To study the MRI findings of knee joint injury and the pathalogical basis and clinical significance. Methods: MR images of the knee joint injury were investigated in 35 cases. Results: In 23 cases of meniscus damage, lesions were nodular, linear or radioactive fissure with hyperintense signal within the dark meniscus, extending to or beneath the articular cartilage surface. In 9 cases of cruciate ligament injury, the disorder was a hyperintense shadow which was hyperintense on T 1 WI and hypointense on T 2 WI within the stripe-like, hypointense ligament, accompanying with the alteration of the ligament, which was in a wave shape or discontinued. Dislocation of the tibia was also revealed. In 5 cases of the bilateral collateral ligament damage. The involved thickened ligament had increased signal and blurred edge. In 4 cases of obscure bone fracture, the lesion was located in the metaphysic, manifested a hypo-intense shadow on T 1 WI, diverse on T 2 WI. Conclusion: MRI plays an important role in the diagnosis of the injury of menicus, ligament, and the obscure fracture of knee joint, and provides detailed information for the clinical management.

    2007-04-01

    Full Text Available Abstract Background Training of neuromuscular control has become increasingly important and plays a major role in rehabilitation of subjects with an injury to the anterior cruciate ligament (ACL. Little is known, however, of the influence of this training on knee stiffness during loading. Increased knee stiffness occurs as a loading strategy of ACL-injured subjects and is associated with increased joint contact forces. Increased or altered joint loads contribute to the development of osteoarthritis. The aim of the study was to determine if knee stiffness, defined by changes in knee kinetics and kinematics of gait, step activity and cross-over hop could be reduced through a knee-specific 12-week training programme. Methods A 3-dimensional motion analysis system (VICON and a force plate (AMTI were used to calculate knee kinetics and kinematics before and after 12 weeks of knee-specific training in 12 males recruited from a cohort with ACL injury 16 years earlier. Twelve uninjured males matched for age, sex, BMI and activity level served as a reference group. Self-reported patient-relevant data were obtained by the KOOS questionnaire. Results There were no significant changes in knee stiffness during gait and step activity after training. For the cross-over hop, increased peak knee flexion during landing (from 44 to 48 degrees, p = 0.031 and increased internal knee extensor moment (1.28 to 1.55 Nm/kg, p = 0.017 were seen after training, indicating reduced knee stiffness. The KOOS sport and recreation score improved from 70 to 77 (p = 0.005 and was significantly correlated with the changes in knee flexion during landing for the cross-over hop (r = 0.6, p = 0.039. Conclusion Knee-specific training improved lower extremity kinetics and kinematics, indicating reduced knee stiffness during demanding hop activity. Self-reported sport and recreational function correlated positively with the biomechanical changes supporting a clinical importance of the

    Full Text Available Osteoarthritis (OA is more common in the knee compared to the ankle joint. This can not be explained exclusively by anatomical and biomechanical differences. The aim of this study is to analyze and compare the injury pattern (clinically and the cartilage lesions (arthroscopically of knee and ankle joints in a cohort of patients from the same catchment area. A retrospective study of the clinical data of 3122 patients (2139 outpatients and 983 inpatients was performed, who were treated due to an injury of the knee and ankle joint. Statistical analysis was performed using SigmaStat 3.0 (SPSS Inc, Chicago, USA. There is a higher prevalence of injuries in the ankle as compared to the knee joint in this population from the same catchment area. In contrast, high-grade cartilage lesions are more prevalent in the knee, whereas low grade cartilage lesions are equally distributed between knee and ankle. From this data it can be concluded that the frequency of injuries and the injury pattern of knee versus ankle joints do not correlate with the severity of cartilage lesions and may therefore have no direct influence on the differential incidence of OA in those two joints.

    Anterior cruciate ligament (ACL) tear is a common injury in sports and often occurs during landing from a jump. To synthesize the evidence on the effects of injury prevention programs (IPPs) on landing biomechanics as they relate to the ligament, quadriceps, trunk, and leg dominance theories associated with ACL injury risk. Meta-analysis. Six electronic databases were searched for studies that investigated the effect of IPPs on landing task biomechanics. Prospective studies that reported landing biomechanics at baseline and post-IPP were included. Results from trunk, hip, and knee kinematics and kinetics related to the ACL injury theories were extracted, and meta-analyses were performed when possible. The criteria were met by 28 studies with a total of 466 participants. Most studies evaluated young females, bilateral landing tasks, and recreational athletes, while most variables were related to the ligament and quadriceps dominance theories. An important predictor of ACL injury, peak knee abduction moment, decreased ( P = .01) after the IPPs while other variables related to the ligament dominance theory did not change. Regarding the quadriceps dominance theory, after the IPPs, angles of hip flexion at initial contact ( P = .009), peak hip flexion ( P = .002), and peak knee flexion ( P = .007) increased, while knee flexion at initial contact did not change ( P = .18). Moreover, peak knee flexion moment decreased ( P = .005) and peak vertical ground-reaction force did not change ( P = .10). The exercises used in IPPs might have the potential to improve landing task biomechanics related to the quadriceps dominance theory, especially increasing peak knee and hip flexion angles. Importantly, peak knee abduction moment decreased, which indicates that IPPs influence a desired movement strategy to help athletes overcome dangerous ligament dominance loads arising from lack of frontal plane control during dynamic tasks. The lack of findings for some biomechanical variables

    The objective of the study was to evaluate the characteristic findings in tears of the anterior cruciate ligament(ACL) and associated injury at MR imaging. We reviewed the findings of MR images and the corresponding arthroscopic results of 32 patients with ACL tears. We evaluated the signal intensity and contour of ACL surrounding bony structures, menisci and associated injury of the knee joint. Complete ACL tears were present in 25 patients and partial ACL tears were in 7 patients. Complete ACL tears showed heterogenously increased signal intensity with contour bulging of the ACL in 14 patients (56%) and without bulging or absence in 11 patients(44%). Most patients torn ACL with contour bulging(12/14) had bone bruise, but only one patient torn ACL without bulging contour had bone bruise. ACL with thin continuous low signal band surrounding heterogenously increased signal intensity suggests partial tear which was seen in three patients of seven proved partial ACL tears. Combined bone injury in ACL tear were in 23 patients (73%) and most of these(22/23) were at midportion of lateral notch of femur and/or posterior portion of lateral tibial plateu. Deepening of lateral notch of femur were noted in 17 patients(53%). Associated injuries of the other ligaments of knee joint were buckling of the posterior cruciate ligament(16/32, 50%) and tears of the medial collateral ligament(11/32, 34%). Posterior horns of menisci were more frequent site of combined injury within menisci in patients with ACL tear. Acute tearing of ACL in MRI is seen as heterogenously increased signal intensity with contour bulging of ACL and combined bone bruises. Patients with torn ACL frequently have various combined injury. In patient with knee injury, these associated or ancillary findings suggest that ACL tear is present

  3. A HYPOTHESIS: COULD PORTABLE NATURAL GRASS BE A RISK FACTOR FOR KNEE INJURIES?

    2008-03-01

    Full Text Available Previous study has shown a likely link between increased shoe- surface traction and risk of knee Anterior Cruciate Ligament (ACL injury. Portable natural grass systems are being used more often in sport, but no study to date has investigated their relative safety. By their nature, they must have high resistance to falling apart and therefore newly laid systems may be at risk of creating excessive shoe-surface traction. This study describes two clusters of knee injuries (particularly non-contact ACL injuries, each occurring to players of one professional football team at single venue, using portable grass, in a short space of time. The first series included two ACL injuries, one posterolateral complex disruption and one lateral ligament tear occurring in two rugby league games on a portable bermudagrass surface in Brisbane, Australia. The second series included four non-contact ACL injuries over a period of ten weeks in professional soccer games on a portable Kentucky bluegrass/perennial ryegrass surface in Barcelona, Spain. Possible intrinsic risk factors are discussed but there was no common risk shared by the players. Although no measures of traction were made at the Brisbane venue, average rotational traction was measured towards the end of the injury cluster at Camp Nou, Barcelona, to be 48 Nm. Chance undoubtedly had a part to play in these clusters, but the only obvious common risk factor was play on a portable natural grass surface soon after it was laid. Further study is required to determine whether portable natural grass systems may exhibit high shoe-surface traction soon after being laid and whether this could be a risk factor for knee injury

    Hamstring strain injuries (HSIs) represent the most common cause of lost playing time in rugby union. Eccentric knee flexor weakness and between-limb imbalance in eccentric knee flexor strength are associated with a heightened risk of HSIs in other sports; however, these variables have not been explored in rugby union. To determine if lower levels of eccentric knee flexor strength or greater between-limb imbalance in this parameter during the Nordic hamstring exercise are risk factors for HSIs in rugby union. Cohort study; Level of evidence, 2. This prospective study was conducted over the 2014 Super Rugby and Queensland Rugby Union seasons. In total, 178 rugby union players (mean age, 22.6 ± 3.8 years; mean height, 185.0 ± 6.8 cm; mean weight, 96.5 ± 13.1 kg) had their eccentric knee flexor strength assessed using a custom-made device during the preseason. Reports of previous hamstring, quadriceps, groin, calf, and anterior cruciate ligament injuries were also obtained. The main outcome measure was the prospective occurrence of HSIs. Twenty players suffered at least 1 HSI during the study period. Players with a history of HSIs had a 4.1-fold (95% CI, 1.9-8.9; P = .001) greater risk of subsequent HSIs than players without such a history. Between-limb imbalance in eccentric knee flexor strength of ≥15% and ≥20% increased the risk of HSIs by 2.4-fold (95% CI, 1.1-5.5; P = .033) and 3.4-fold (95% CI, 1.5-7.6; P = .003), respectively. Lower eccentric knee flexor strength and other prior injuries were not associated with an increased risk of future HSIs. Multivariate logistic regression revealed that the risk of reinjuries was augmented in players with strength imbalances. Previous HSIs and between-limb imbalance in eccentric knee flexor strength were associated with an increased risk of future HSIs in rugby union. These results support the rationale for reducing imbalance, particularly in players who have suffered a prior HSI, to mitigate the risk of future

Despite advancements in surgical techniques and enhanced rehabilitation, athletes returning to cutting, pivoting, and jumping sports after a knee injury are at greater risk of sustaining a second injury. The clinical utility of objective criteria presents a decision-making challenge to ensure athletes are fully rehabilitated and ...

  7. Behaviour, the key factor for sports injury prevention.

    Safety in sports and physical activity is an important prerequisite for continuing participation in sports, as well as for maintenance of a healthy physically active lifestyle. For this reason, prevention, reduction and control of sports injuries are important goals for society as a whole. Recent advances in sports medicine discuss the need for research on real-life injury prevention. Such views call for a more behavioural approach when it comes to actual sports injury prevention. Nevertheless, the role of behaviour in sports injury prevention remains under-researched. In order to push the field of sports injury prevention forward, this article provides an overview of the relationship between behaviour and sports injury risk. Different types of behaviour relate to injury risk factors and injury mechanisms. Behaviour that influences risk factors and injury mechanisms is not confined only to the athlete. Various types of behaviour by, for example, the coach, referee, physical therapist or sports associations, also influence risk factors and injury mechanisms. In addition, multiple behaviours often act together. Some types of behaviour may directly affect injury risk and are by definition a risk factor. Other behaviours may only affect risk factors and injury mechanisms, and influence injury risk indirectly. Recent ideas on injury prevention that call for studies on real-life injury prevention still rely heavily on preventive measures that are established through efficacy research. A serious limitation in such an approach is that one expects that proven preventive measures will be adopted if the determinants and influences of sports safety behaviours are understood. Therefore, if one truly wants to prevent sports injuries in a real-life situation, a broader research focus is needed. In trying to do so, we need to look at lessons learned from other fields of injury prevention research.

    Exercise-based training programmes are commonly used to prevent sports injuries but programme effectiveness within community men's team sport is largely unknown. To present the intention-to-treat analysis of injury outcomes from a clustered randomised controlled trial in community Australian football. Players from 18 male, non-elite, community Australian football clubs across two states were randomly allocated to either a neuromuscular control (NMC) (intervention n=679 players) or standard-practice (control n=885 players) exercise training programme delivered as part of regular team training sessions (2× weekly for 8-week preseason and 18-week regular-season). All game-related injuries and hours of game participation were recorded. Generalised estimating equations, adjusted for clustering (club unit), were used to compute injury incidence rates (IIRs) for all injuries, lower limb injuries (LLIs) and knee injuries sustained during games. The IIRs were compared across groups with cluster-adjusted Injury Rate Ratios (IRRs). Overall, 773 game injuries were recorded. The lower limb was the most frequent body region injured, accounting for 50% of injuries overall, 96 (12%) of which were knee injuries. The NMC players had a reduced LLI rate compared with control players (IRR: 0.78 (95% CI 0.56 to 1.08), p=0.14.) The knee IIR was also reduced for NMC compared with control players (IRR: 0.50 (95% CI 0.24 to 1.05), p=0.07). These intention-to-treat results indicate that positive outcomes can be achieved from targeted training programmes for reducing knee and LLI injury rates in men's community sport. While not statistically significant, reducing the knee injury rate by 50% and the LLI rate by 22% is still a clinically important outcome. Further injury reductions could be achieved with improved training attendance and participation in the programme. Published by the BMJ Publishing Group Limited.

    Full Text Available Medial collateral ligament injury during primary total knee arthroplasty is a recognised complication potentially resulting in valgus instability, suboptimal patient outcomes and a higher rate of revision or reoperation. Options for management include primary repair with or without augmentation, reconstruction or immediate conversion to prosthesis with greater constraint, in conjunction with various postoperative rehabilitation protocols. Inconsistent recommendations throughout the orthopaedic literature have made the approach to managing this complication problematic. The objective of this study was to review the available literature to date comparing intraoperative and postoperative management options for primary total knee arthroplasty complicated by recognised injury to the medial collateral ligament. This systematic literature review was prospectively registered with PROSPERO (#CRD42014008866 and performed in accordance with PRISMA guidelines including a PRISMA flow diagram. Five articles satisfied the inclusion criteria. Each was a retrospective, observational cohort or case series with small numbers reported, inconsistent methodology and incompletely reported outcomes. Four of the five studies managing medial collateral ligament injury during total knee arthroplasty (47/84 patients with direct repair with or without autograft augmentation reported good outcomes with no revision or reoperation required for symptomatic instability over a follow-up period of 16 months to almost 8 years. The fifth study with a follow-up to 10 years and a high rate of conversion to unlinked semi constrained total knee arthroplasty implant (30/37 patients reported a greater incidence of revision due to instability, in patients in whom the medial collateral ligament injury was directly repaired without added constraint. Overall balance of evidence is in favour of satisfactory outcomes without symptomatic instability following direct repair with or without

    To understand the incidence of violence injury and its prevention in China, and provide reference for the prevention and control of violence injury. The violence injury data in China were collected from national death surveillance data set (2006-2013) and national injury surveillance system (2013) for the descriptive epidemiological analysis on the incidence of violence injury and related death. The laws and policies about violence injury prevention, related data collection capacity and violence injury prevention programs in China were described. The violence injury mortality declined by 46.3% during 2006-2013 from 1.21/100000 to 0.65/100000. The incidence of violence injury death in males peaked in age group 30-34 years (1.42/100000), and it was low in age groupviolence injury death were found in females, i.e. 0.84/100000 in infants, 0.72/100000 in age group 30-34 years and 1.18/100000 in age group≥85 years. The laws and policies about violence injury prevention were imperfect, and the data about violence injury were limited. Most prevention programs were limited in scale and duration. The crude and standardized violence injury mortality declined in China during 2006-2013. It is necessary to conduct gender specific prevention strategies and improve the related law and policy development, data collection and prevention service.

    Construction workers are frequently exposed to various types of injury-inducing hazards. There are a number of injury prevention interventions, yet their effectiveness is uncertain. To assess the effects of interventions for preventing injuries in construction workers. We searched the Cochrane Injuries Group's specialised register, CENTRAL (issue 3), MEDLINE, Embase and PsycINFO up to April 2017. The searches were not restricted by language or publication status. We also handsearched the reference lists of relevant papers and reviews. Randomised controlled trials, controlled before-after (CBA) studies and interrupted time-series (ITS) of all types of interventions for preventing fatal and non-fatal injuries among workers at construction sites. Two review authors independently selected studies, extracted data and assessed their risk of bias. For ITS studies, we re-analysed the studies and used an initial effect, measured as the change in injury rate in the year after the intervention, as well as a sustained effect, measured as the change in time trend before and after the intervention. Seventeen studies (14 ITS and 3 CBA studies) met the inclusion criteria in this updated version of the review. The ITS studies evaluated the effects of: introducing or changing regulations that laid down safety and health requirements for the construction sites (nine studies), a safety campaign (two studies), a drug-free workplace programme (one study), a training programme (one study), and safety inspections (one study) on fatal and non-fatal occupational injuries. One CBA study evaluated the introduction of occupational health services such as risk assessment and health surveillance, one evaluated a training programme and one evaluated the effect of a subsidy for upgrading to safer scaffoldings. The overall risk of bias of most of the included studies was high, as it was uncertain for the ITS studies whether the intervention was independent from other changes and thus could be

    Full Text Available BACKGROUND : Anterior C ruciate L igament (ACL tear is a common sports injury of the knee. There are a lot of controversies related to the management of this injury and more than 2000 papers have been published on the various aspects of the topic. Arthroscopic reconstruction of the ACL with autogenous graft material is widely used nowadays. The two most commonly used grafts are the central one - third of the patellar ligament (bone - tendon - bone, BTB and the hamstring tendon ( S emitendinosus - gracilis, STG construct but the former graft leads to increased donor site morbidity & hurdles in postoperative rehab & pain. The aim of the study is to study the Arthroscopic management of anterior cruciate ligament injury of knee joint using quadrupled hamstring graft. METHOD: The study was carried out on 30 cases of anterior cruciate ligament injury of knee joint attending the OPD and emergency of department of Orthopaedics, Silchar Medical College & Hospital who met the inclusion criteria. An informed consent was obtained from each patient prior to participation in the study. All the patients were examined in detail and worked up to obtain pre - anaesthetic clearance. X - rays and MRI were done routinely in all the cases. Clinical and radiological parameters were recorded. Arthroscopic anterior cruciate ligament reconstruction with quadrupled hamstring graft was done in all the patients. Concomitant meniscal inju ries were treated according to the merit of the injury. Patients were followed up at regular intervals and outcome variables were assessed and recorded. RESULTS: Results of our study clearly showed that arthroscopic ACL reconstruction using quadrupled hamstring graft is a safe, effective and reproducible procedure in restoring knee function with minimal donor site morbidity. At follow up evaluation, all patients had good outcomes in terms of clinical stability, range of motion and general symptoms. CONCLUSION: From the results in this study

    The aim of this study was to assess the costs and effectiveness of selective short magnetic resonance imaging (MRI) in patients with acute knee injury. A model was developed to evaluate the selective use of MRI in patients with acute knee injury and no fracture on radiography based on the results of a trial in which 208 patients were randomized between radiography only and radiography plus MRI. We analyzed medical (diagnostic and therapeutic) costs, quality of life, duration of diagnostic workup, number of additional diagnostic examinations, time absent from work, and time to convalescence during a 6-month follow-up period. Quality of life was lowest (EuroQol at 6 weeks 0.61 (95% CI 0.54-0.67)); duration of diagnostic workup, absence from work, and time to convalescence were longest; and the number of diagnostic examinations was largest with radiography only. These outcomes were more favorable for both MRI strategies (EuroQol at 6 weeks 0.72 (95% CI 0.67-0.77) for both). Mean total costs were 2,593 euros (95% CI 1,815-3,372) with radiography only, 2,116 euros (95% CI 1,488-2,743) with radiography plus MRI, and 1,973 euros (95% CI 1,401-2,543) with selective MRI. The results suggest that selective use of a short MRI examination saves costs and potentially increases effectiveness in patients with acute knee injury without a fracture on radiography. (orig.)

    The FIFA 11+ injury prevention program has been shown to decrease the risk of soccer injuries in men and women. The program has also been shown to decrease time loss resulting from injury. However, previous studies have not specifically investigated how the program might impact the rate of anterior cruciate ligament (ACL) injury in male soccer players. The purpose of this study was to examine if the FIFA 11+ injury prevention program can (1) reduce the overall number of ACL injuries in men who play competitive college soccer and whether any potential reduction in rate of ACL injuries differed based on (2) game versus practice setting; (3) player position; (4) level of play (Division I or II); or (5) field type. This study was a prospective cluster randomized controlled trial, which was conducted in 61 Division I and Division II National Collegiate Athletic Association men's soccer teams over the course of one competitive soccer season. The FIFA 11+ is a 15- to 20-minute on-the-field dynamic warm-up program used before training and games and was utilized as the intervention throughout the entire competitive season. Sixty-five teams were randomized: 34 to the control group (850 players) and 31 to the intervention group (675 players). Four intervention teams did not complete the study and did not submit their data, noting insufficient time to complete the program, reducing the number for per-protocol analysis to 61. Compliance to the FIFA 11+ program, athletic exposures, specific injuries, ACL injuries, and time loss resulting from injury were collected and recorded using a secure Internet-based system. At the end of the season, the data in the injury surveillance system were crosshatched with each individual institution's internal database. At that time, the certified athletic trainer signed off on the injury collection data to confirm their accuracy and completeness. A lower proportion of athletes in the intervention group experienced knee injuries (25% [34 of

    OBJECTIVE: To adapt the Knee injury and Osteoarthritis Outcome Score (KOOS) into French and to evaluate the psychometric properties of this new version. METHODS: The French version of the KOOS was developed according to cross-cultural guidelines by using the "translation-back translation" method...... to ensure content validity. KOOS data were then obtained in patients with symptomatic knee osteoarthritis (OA). The translated questionnaire was evaluated in two knee OA population groups, one with no indication for joint replacement (medicine), and the other waiting for joint replacement (surgery......). The psychometric properties evaluated were feasibility: percentage of responses, floor and ceiling effects; construct validity: internal consistency using Cronbach's alpha, correlations with osteoarthritis knee and hip quality of life domains using Spearman's rank test, and known group comparison between medicine...

  17. Practice guidelines for the management of multiligamentous injuries of the knee

    Directory of Open Access Journals (Sweden)

    Ankit Goyal

    2017-01-01

    Full Text Available Background: Multiligamentous injuries of knee remain a gray area as far as guidelines for management are concerned due to absence of large-scale, prospective controlled trials. This article reviews the recent evidence-based literature and trends in treatment of multiligamentous injuries and establishes the needful protocol, keeping in view the current concepts. Materials and Methods: Two reviewers individually assessed the available data indexed on PubMed and Medline and compiled data on incidence, surgical versus nonsurgical treatment, timing of surgery, and repair versus reconstruction of multiligamentous injury. Results: Evolving trends do not clearly describe treatment, but most studies have shown increasing inclination toward an early, staged/single surgical procedure for multiligamentous injuries involving cruciate and collateral ligaments. Medial complex injuries have shown better results with conservative treatment with surgical reconstruction of concomitant injuries. Conclusion: Multiligamentous injury still remains a gray area due to unavailability of a formal guideline to treatment in the absence of large-scale, blinded prospective controlled trials. Any in multiligamentous injuries any intervention needs to be individualized by the presence of any life- or limb-threatening complication. The risks and guarded prognosis with both surgical and non-surgical modalities of treatment should be explained to patient and relations.

  18. Need for Injury Prevention Education In Medical School Curriculum

    Vaca, Federico E

    2010-02-01

    Full Text Available Injury is the leading cause of death and disability among the U.S. population aged 1 to 44 years. In 2006 more than 179,000 fatalities were attributed to injury. Despite increasing awareness of the global epidemic of injury and violence, a considerable gap remains between advances in injury-prevention research and prevention knowledge that is taught to medical students. This article discusses the growing need for U.S medical schools to train future physicians in the fundamentals of injury prevention and control. Teaching medical students to implement injury prevention in their future practice should help reduce injury morbidity and mortality. Deliberate efforts should be made to integrate injury-prevention education into existing curriculum. Key resources are available to do this. Emergency physicians can be essential advocates in establishing injury prevention training because of their clinical expertise in treating injury. Increasing the number of physicians with injury- and violence- prevention knowledge and skills is ultimately an important strategy to reduce the national and global burden of injury.

    Background/aim Poor frontal plane knee control can manifest as increased dynamic knee valgus during athletic tasks. The purpose of this study was to investigate the association between frontal plane knee control and the risk of acute lower extremity injuries. In addition, we wanted to study if the single-leg squat (SLS) test can be used as a screening tool to identify athletes with an increased injury risk. Methods A total of 306 basketball and floorball players participated in the baseline SLS test and a 12-month injury registration follow-up. Acute lower extremity time-loss injuries were registered. Frontal plane knee projection angles (FPKPA) during the SLS were calculated using a two-dimensional video analysis. Results Athletes displaying a high FPKPA were 2.7 times more likely to sustain a lower extremity injury (adjusted OR 2.67, 95% CI 1.23 to 5.83) and 2.4 times more likely to sustain an ankle injury (OR 2.37, 95% CI 1.13 to 4.98). There was no statistically significant association between FPKPA and knee injury (OR 1.49, 95% CI 0.56 to 3.98). The receiver operating characteristic curve analyses indicated poor combined sensitivity and specificity when FPKPA was used as a screening test for lower extremity injuries (area under the curve of 0.59) and ankle injuries (area under the curve of 0.58). Conclusions Athletes displaying a large FPKPA in the SLS test had an elevated risk of acute lower extremity and ankle injuries. However, the SLS test is not sensitive and specific enough to be used as a screening tool for future injury risk. PMID:29387448

    The aim of the study was to describe objective and self-reported knee function for athletes who have returned to elite handball and football play after an ACL injury, comparing these to non-injured players at the same level. A total of 414 handball and 444 football players completed baseline tests from 2007 through 2014, examining lower extremity strength, dynamic balance, knee laxity, and knee function (KOOS questionnaire). Measures were compared between injured and non-injured legs and between injured legs and legs of controls. Eighty (9.3%) of the 858 players reported a previous ACL injury, 1-6 years post-injury (3.5±2.5 years), 49 handball (61.3%) and 31 football players (38.7%). We found no difference in strength or dynamic balance between previously ACL-injured (N=80) and non-injured players legs (N=1556). However, lower quadriceps (6.3%, 95% CI: 3.2-9.2) and hamstrings muscle strength (6.1%, 95% CI: 3.3-8.1) were observed in previously ACL-injured legs compared to the non-injured contralateral side (N=80). ACL-injured knees displayed greater joint laxity than the contralateral knee (N=80, 17%, 95% CI: 8-26) and healthy knees (N=1556, 23%, 95% CI: 14-33). KOOS scores were significantly lower for injured knees compared to knees of non-injured players. ACL-injured players who have successfully returned to elite sport have comparable strength and balance measures as their non-injured teammates. Subjective perception of knee function is strongly affected by injury history, with clinically relevant lower scores for the KOOS subscores Pain, Function, Sport, and Quality Of Life. © 2017 John Wiley & Sons A/S.

    Preventable thermal injuries in professional kitchen workers have been identified, and we have introduced a protective garment. Because of the nature of their occupation, kitchen workers are prone to thermal injuries. It has been our experience that the majority of these injuries are scald injuries on the ankles and dorsum of the feet. We propose that a protective garment, such as a waterproof shoe and garter, could reduce the incidence of these injuries.

    Anterior cruciate ligament injury results in altered kinematics and kinetics in the knee and hip joints that persist despite surgical reconstruction and rehabilitation. Abnormal movement patterns and a history of osteoarthritis are risk factors for articular cartilage degeneration in additional joints. The purpose of this study was to determine if hip joint biomechanics early after anterior cruciate ligament injury and reconstruction differ between patients with and without post-traumatic knee osteoarthritis 5years after reconstruction. The study's rationale was that individuals who develop knee osteoarthritis after anterior cruciate ligament injury may also demonstrate large alterations in hip joint biomechanics. Nineteen athletes with anterior cruciate ligament injury completed standard gait analysis before (baseline) and after (post-training) extended pre-operative rehabilitation and at 6months, 1year, and 2years after reconstruction. Weightbearing knee radiographs were completed 5years after reconstruction to identify medial compartment osteoarthritis. Five of 19 patients had knee osteoarthritis at 5years after anterior cruciate ligament reconstruction. Patients with knee osteoarthritis at 5years walked with smaller sagittal plane hip angles (P: 0.043) and lower sagittal (P: 0.021) and frontal plane (P: 0.042) external hip moments in the injured limb before and after reconstruction compared to those without knee osteoarthritis. The current findings suggest hip joint biomechanics may be altered in patients who develop post-traumatic knee osteoarthritis. Further study is needed to confirm whether the risk of non-traumatic hip pathology is increased after anterior cruciate ligament injury and if hip joint biomechanics influence its development.

    Lower limb injury risk assessment was proposed, based on isokinetic examination that is a part of standard athlete's biomechanical evaluation performed mainly twice a year. Information about non-contact knee injury (or lack of the injury) sustained within twelve months after isokinetic test, confirmed in USG were verified. Three the most common types of football injuries were taken into consideration: anterior cruciate ligament (ACL) rupture, hamstring and quadriceps muscles injuries. 22 parameters, obtained from isokinetic tests were divided into 4 groups and used as input parameters of five feedforward artificial neural networks (ANNs). The 5th group consisted of all considered parameters. The networks were trained with the use of Levenberg-Marquardt backpropagation algorithm to return value close to 1 for the sets of parameters corresponding injury event and close to 0 for parameters with no injury recorded within 6 - 12 months after isokinetic test. Results of this study shows that ANN might be useful tools, which simplify process of simultaneous interpretation of many numerical parameters, but the most important factor that significantly influence the results is database used for ANN training.

    Objective: To assess the efficacy of FS-3D-FISP, FS-2D-FLASH and SE-T 1 WI sequences in the detection of articular cartilage injury of the knee. Methods: 34 consecutive patients with persistent symptoms of knee pain who were scheduled for arthroscopy underwent MR examination of the knee on a 1.5 TMR unit prior to arthroscopy. The 2D MR images were transferred to a workstation and processed tow-dimensional and three-dimensional reconstruction. Results: Compared with the arthroscopy, the sensitivity, specificity, and Kappa were 91.4%, 97%, and 0.818, respectively with FS-3D-F ISP sequence, 77.1%, 98%, and 0.531, respectively with FS-2D-FLASH sequence, 70%, 99%, and 0.518, respectively with SE-T 1 WI sequence. In the cases that had no acute trauma, 77.6% lesions were shown lower SI on T 1 -WI in the region of the subchondral bone and marrow near the lesions, and higher SI on FS-3D-FISP and FS-2D-FLASH sequences. Conclusion: Comparing with arthroscopy, the diagnosis accuracy of FS-3D-FISP sequence is obviously better than that of FS-2D-FLASH and SE-T 1 WI sequences. Correlation between FS-3D-FISP sequence and arthroscopy in detecting articular cartilage injury is remarkeble. Abnormal signal in the subchondral bone and marrow is an important indirect sign of articular cartilage injury. Three-dimensional reconstruction of articular cartilage is helpful for localization of the lesions after injury. (authors)

    Lower limb injuries in sport are increasingly prevalent and responsible for large economic as well as personal burdens. In this review we seek to determine which easily implemented functional neuromuscular warm-up strategies are effective in preventing lower limb injuries during sports participation and in which sporting groups they are effective. Seven electronic databases were searched from inception to January 2012 for studies investigating neuromuscular warm-up strategies and injury prevention. The quality of each included study was evaluated using a modified version of the van Tulder scale. Data were extracted from each study and used to calculate the risk of injury following application of each evaluated strategy. Nine studies were identified including six randomized controlled trials (RCT) and three controlled clinical trials (CCT). Heterogeneity in study design and warm-up strategies prevented pooling of results. Two studies investigated male and female participants, while the remaining seven investigated women only.

    Full Text Available Abstract Background Lower limb injuries in sport are increasingly prevalent and responsible for large economic as well as personal burdens. In this review we seek to determine which easily implemented functional neuromuscular warm-up strategies are effective in preventing lower limb injuries during sports participation and in which sporting groups they are effective. Methods Seven electronic databases were searched from inception to January 2012 for studies investigating neuromuscular warm-up strategies and injury prevention. The quality of each included study was evaluated using a modified version of the van Tulder scale. Data were extracted from each study and used to calculate the risk of injury following application of each evaluated strategy. Results Nine studies were identified including six randomized controlled trials (RCT and three controlled clinical trials (CCT. Heterogeneity in study design and warm-up strategies prevented pooling of results. Two studies investigated male and female participants, while the remaining seven investigated women only. Risk Ratio (RR statistics indicated 'The 11+' prevention strategy significantly reduces overall (RR 0.67, confidence interval (CI 0.54 to 0.84 and overuse (RR 0.45, CI 0.28 to 0.71 lower limb injuries as well as knee (RR 0.48, CI 0.32 to 0.72 injuries among young amateur female footballers.

    Identifying risk factors for knee pain and anterior cruciate ligament (ACL) injury can be an important step in the injury prevention cycle. We evaluated two unique prospective cohorts with similar populations and methodologies to compare the incidence rates and risk factors associated with patellofemoral pain (PFP) and ACL injury. The 'PFP cohort' consisted of 240 middle and high school female athletes. They were evaluated by a physician and underwent anthropometric assessment, strength testing and three-dimensional landing biomechanical analyses prior to their basketball season. 145 of these athletes met inclusion for surveillance of incident (new) PFP by certified athletic trainers during their competitive season. The 'ACL cohort' included 205 high school female volleyball, soccer and basketball athletes who underwent the same anthropometric, strength and biomechanical assessment prior to their competitive season and were subsequently followed up for incidence of ACL injury. A one-way analysis of variance was used to evaluate potential group (incident PFP vs ACL injured) differences in anthropometrics, strength and landing biomechanics. Knee abduction moment (KAM) cut-scores that provided the maximal sensitivity and specificity for prediction of PFP or ACL injury risk were also compared between the cohorts. KAM during landing above 15.4 Nm was associated with a 6.8% risk to develop PFP compared to a 2.9% risk if below the PFP risk threshold in our sample. Likewise, a KAM above 25.3 Nm was associated with a 6.8% risk for subsequent ACL injury compared to a 0.4% risk if below the established ACL risk threshold. The ACL-injured athletes initiated landing with a greater knee abduction angle and a reduced hamstrings-to-quadriceps strength ratio relative to the incident PFP group. Also, when comparing across cohorts, the athletes who suffered ACL injury also had lower hamstring/quadriceps ratio than the players in the PFP sample (p15 Nm of knee abduction load

    Full Text Available OBJECTIVE The purpose of this study was to evaluate the reliability of clinical diagnosis compared to MRI findings in ligamentous and meniscal injuries with respect to arthroscopic confirmation as a gold standard. METHODS 485 patients with knee injuries were prospectively assessed by clinical evaluation and magnetic resonance imaging and correlated after therapeutic arthroscopy. The overall accuracy, clinically productive values of sensitivity and specificity was derived. The actual value of the test with respect to positive predictive and negative predictive value was also derived, taking arthroscopic findings as confirmatory. The overall partial and total agreement among the clinical, MRI and arthroscopy was documented. RESULTS The overall accuracy for clinical examination was 85, 92, 100 and 100 and accuracy for MRI was 90, 97, 97 and 97 for detecting medial meniscus, lateral meniscus, ACL and PCL tears respectively. Clinically lateral meniscus tears are difficult to diagnose clinically with negative predictive value (90 whereas ACL injuries do not need MRI for diagnosis as evident by a high negative predictive value (100 of clinical examination. Total agreement with the clinical findings confirmed by arthroscopy was 64.40% which was relatively high as compared to total agreement of MRI findings which was only 31.50%. We found similar total agreement versus total disagreement of both clinical and MRI to be only 2.74% indicating very high accuracy in clinical diagnosis of meniscal and ligamentous injuries combined. CONCLUSION The clinical evaluation alone is sufficient to diagnose meniscal and ACL/PCL pathologies and MRI should be considered only as a powerful negative diagnostic tool. The arthroscopy decision should not be heavily dependent on MRI for ligamentous injuries but reverse is true for meniscal lesions. MR evaluation functions as a powerful negative diagnostic tool to rule out doubtful and complex knee injuries.

    Background: Injury as a cause of significant morbidity and mortality has remained fairly stable in countries with developed economies. Although injury prevention often is conceptualised as a biomedical construct, such a reductionist perspective overlooks the importance of the psychological, environmental, and sociocultural conditions as contributing factors to injury and its consequences. This paper describes the potential of the ecological model for understanding the antecedent causes of unintentional injuries and guiding injury prevention approaches. We review the origins and conceptualise the elements of the ecological model and conclude with some examples of applications of ecological approaches to the prevention of unintentional injury and promotion of community safety.

    Methods: A review of the English-language literature on the conceptualization of ecological models in public health and injury prevention, including the application of the ecological model in the prevention of falls and road traffic injuries and in the community safety promotion movement.

    Results: Three dimensions are important in social-ecological systems that comprise key determinants of injuries: 1 the individual and his or her behaviour, 2 the physical environment, and 3 the social environment. Social and environmental determinants have profound impact on population health and in the causation of injuries.

    Conclusions: Social and environmental determinants of injury should be studied with the same energy, urgency, and intellectual rigor as physical determinants. Application of the ecological model in injury prevention shows the most promise in falls injury prevention, road traffic injury prevention, and community safety promotion.

    When players are engaged in the sport of tennis, injuries may occur to the eyes, in the neck, to the shoulder and back, arm and elbow, wrist and hand, and feet. The key to prevention and treatment of these injuries is good coaching and a formal stretching and strengthening program. The drooped "tennis shoulder" of professionals and senior tennis players is a natural response to heavy use. Shoulder elevating exercises are useful when soreness is associated. The treatment of tennis elbow includes wrist extensor stretching, isometrics, and light weightlifting. When a player follows this program, injections or counterforce braces are rarely needed. It is important for the player to bring his racket to the examination so that his stroke mechanics and grip can be checked. Wrist soreness in a tennis player may denote a hamate hook fracture. Special radiographic views are needed to discern the fracture and it is treated with a short arm cast and little finger extension splint. Nonunion of a hamate hook requires excision. The calf pain prodrome of "tennis leg" requires rest and then a stretching program. Tennis shoes should have rolled heels and large toe boxes with reinforced toe bumpers. The physician may have to fashion soft inserts for the tennis shoes; arch supports may be insufficient.

    The risk of sepsis development increases when thermal burns and other trauma occur in combination with exposure to radiation. Only surgical correction of the life-threatening state recommends within 48 hours after irradiation. All other arrangements have to carry out when hemopoiesis recovery will complete. However exposed patients with combined injuries (CI) die during the first two or three weeks mainly due to sepsis. Therefore prophylaxis and preventive therapy of infectious complications are need early. Actual difficulties in choice of valid treatment procedure for acute radiation syndrome (ARS) exhibit additional aggravation under CI. The available facts prove decreasing early therapy efficiency for rather high dose exposure and wound trauma occurrence. The own results showed that bacterial polysaccharide pyrogenal, glycopin (synthetic analogue of muramil-dipeptide), thymus preparations (thymozin, thymotropin, thymogen), tuftsin, heterologic human and bovine immunoglobulins did not modify the low values of 30-day survival under CI (irradiation + thermal burn). Single injection of prodigiozan, zymozan and some other yeast polysaccharides in 1 hr after CI resulted at moderate increasing of survival. The main purpose of this study, which bases upon our understanding of CI pathogenesis, was search more effective means for preventive treatment of combined radiation injuries. Two groups of remedies were under study. The first group included so called 'biological response modifiers' (BRM). These agents may increase host defences to infection, macrophage's activity and hemopoietic growth factor's secretion. The second group included antibiotics that should be directed against the potential gram-negative as well as gram-positive pathogens and simultaneously be useful for selective decontamination of gastrointestinal tract.

    Full Text Available Purpose. The purpose of this study was to evaluate the approach of using an electromagnetic tracking (EMT system for measuring the effects of stepwise, simulated knee injuries on patellofemoral (PF and tibiofemoral (TF kinematics. Methods. Three cadaver knees were placed in a motion rig. EMT sensors were mounted on the patella, the medial/lateral femoral epicondyles, the tibial condyle, and the tibial tuberosity (TT. After determining the motion of an intact knee, three injuries were simulated and the resulting bony motion was tracked. Results. Starting with the intact knee fully extended (0° flexion and bending it to approximately 20°, the patella shifted slightly in the medial direction. Then, while bending the knee to the flexed position (90° flexion, the patella shifted progressively more laterally. After transecting the anterior cruciate ligament (ACL, the base of the medial menisci (MM at the pars intermedia, and the medial collateral ligament (MCL, individual changes were observed. For example, the medial femoral epicondyle displayed a medial lift-off in all knees. Conclusion. We demonstrated that our EMT approach is an acceptable method to accurately measure PF joint motion. This method could also enable visualization and in-depth analysis of in vivo patellar function in total knee arthroplasty, if it is established for routine clinical use.

    To examine dual-energy computed tomography (DECT) in evaluating cruciate ligament injuries. More specifically, the purpose was to assess the optimal keV level in DECT gemstone spectral imaging (GSI) images and to examine the usefulness of collagen-specific color mapping and dual-energy bone removal in the evaluation of cruciate ligaments and the popliteus tendon. At a level 1 trauma center, a 29-month period of emergency department DECT examinations for acute knee trauma was reviewed by two radiologists for presence of cruciate ligament injuries, visualization of the popliteus tendon and the optimal keV level in GSI images. Three different evaluating protocols (GSI, bone removal and collagen-specific color mapping) were rated. Subsequent MRI served as a reference standard for intraarticular injuries. A total of 18 patients who had an acute knee trauma, DECT and MRI were found. On MRI, six patients had an ACL rupture. DECT's sensitivity and specificity to detect ACL rupture were 79 % and 100 %, respectively. The DECT vs. MRI intra- and interobserver proportions of agreement for ACL rupture were excellent or good (kappa values 0.72-0.87). Only one patient had a PCL rupture. In GSI images, the optimal keV level was 63 keV. GSI of 40-140 keV was considered to be the best evaluation protocol in the majority of cases. DECT is a usable method to evaluate ACL in acute knee trauma patients with rather good sensitivity and high specificity. GSI is generally a better evaluation protocol than bone removal or collagen-specific color mapping in the evaluation of cruciate ligaments and popliteus tendon. (orig.)

    Some injury prevention programmes aim to reduce the risk of ACL rupture. Although the most common athletic task leading to ACL rupture is cutting, there is currently no consensus on how injury prevention programmes influence cutting task biomechanics. To systematically review and synthesise the scientific literature regarding the influence of injury prevention programme exercises on cutting task biomechanics. The three largest databases (Medline, EMBASE and CINAHL) were searched for studies that investigated the effect of injury prevention programmes on cutting task biomechanics. When possible meta-analyses were performed. Seven studies met the inclusion criteria. Across all studies, a total of 100 participants received exercises that are part of ACL injury prevention programmes and 76 participants served in control groups. Most studies evaluated variables associated with the quadriceps dominance theory. The meta-analysis revealed decreased lateral hamstrings electromyography activity (p ≤ 0.05) while single studies revealed decreased quadriceps and increased medial hamstrings activity and decreased peak knee flexion moment. Findings from single studies reported that ACL injury prevention exercises reduce neuromuscular deficits (knee valgus moment, lateral trunk leaning) associated with the ligament and trunk dominance theories, respectively. The programmes we analysed appear most effective when they emphasise individualised biomechanical technique correction and target postpubertal women. The exercises used in injury prevention programmes have the potential to improve cutting task biomechanics by ameliorating neuromuscular deficits linked to ACL rupture, especially when they emphasise individualised biomechanical technique correction and target postpubertal female athletes.

    2015-01-01

    Full Text Available A multiple-ligament knee injury that includes posterolateral corner (PLC disruption often causes palsy of the common peroneal nerve (CPN, which occurs in 44% of cases with PLC injury and biceps femoris tendon rupture or avulsion of the fibular head. Approximately half of these cases do not show functional recovery. This case report aims to present a criteria-based approach to the operation and postoperative management of CPN palsy that resulted from a multiple-ligament knee injury in a 22-year-old man that occurred during judo. We performed a two-staged surgery. The first stage was to repair the injuries to the PLC and biceps femoris. The second stage involved anterior cruciate ligament reconstruction. The outcomes were excellent, with a stable knee, excellent range of motion, and improvement in the palsy. The patient was able to return to judo competition 27 weeks after the injury. To the best of our knowledge, this is the first case report describing a return to sports following CPN palsy with multiple-ligament knee injury.

    Gymnastic school sport injuries account for a significant morbidity and mortality among children and adolescents. Preventive issues may be derived from a thorough in-depth analysis of the pattern and circumstances of gymnastic injuries. During a school year among 3993 schools in 43 889 classes with 993 056 pupils 2234 school sport injuries have been reported to the Gemeinde Unfall Versicherung (GUV) Niedersachsen, Germany. Gymnastic sport injuries account for 18 % (403 accidents), which is second after ball sports injuries. Regarding the distribution of the gymnastic disciplines, vault was the major discipline with 34 %, followed by floor exercise (21.3 %), mini- and competition trampoline (16.8 %), and parallel bars (8.2 %). The analysis of the type of injury during vault accidents revealed contusion (31 %) as the predominant injury, followed by sprains (15.4 %), and fractures (15.4 %). Floor exercise injuries distributed among distorsions (26.7 %), contusions (18.6 %), muscle tears (14 %). Back injuries especially of the cervical and thoracic spine, accounted for 40 % of all their injuries. Minor head injuries account for 4.7 % of all floor exercise injuries. Mini-trampoline injuries distribute among contusions (30 %), fractures (22.5 %), distorsions (7.5 %). 21.8 % collisions were noted against a box in comparison to 6.8 % in case of the horse. Gymnast injuries account for a significant number of all school sport related injuries. Vault and floor exercise account for the vast majority of all injuries, with alarming high numbers of spine injuries during floor exercise and mini-trampoline. A preservation of a high level of attention during a sport lesson, safety measures including appropriate mats and landing zones are mandatory to reduce injuries. Muscle injuries and ankle sprains can be prevented by a prospective proprioceptive training intervention to be implemented in school sports.

    2018-02-02

    To gather epidemiological information related to all steps of Van Mechelen's "sequence of prevention" for musculoskeletal injuries among adult recreational football players. A systematic review of the scientific literature was conducted in Medline via Pubmed. Therefore, two highly sensitive search strategies based on three groups of keywords (and related search terms) were used. In total, 33 relevant original studies were included in our systematic review. The results of our systematic review showed that the incidence of musculoskeletal injuries among recreational adult football players ranged from 9.6 to 15.8 injuries per 1000 exposure hours. These injuries are especially located in the ankle, knee, groin and hamstring, being associated with previous injury and match exposure. The FIFA11 + injury prevention programme and the Nordic Hamstring Exercise (NHE) were found to be effective for the reduction or prevention of musculoskeletal injuries among adult recreational football players. Our systematic review showed that musculoskeletal injuries are common among recreational adult football players, while effective preventive programmes are available. Further studies should focus on the identification and understanding of the key factors responsible for the optimal adoption, implementation and maintenance of these measures.

  8. S-13: Interventions for Prevention and Rehabilitation of Hamstring Injuries

    Directory of Open Access Journals (Sweden)

    Reza Rahimi Moghaddam

    2017-03-01

    Full Text Available INTRODUCTION: The hamstring muscles have very important role in the stabilization of body posture, movement of the lower extremities and trunk movements in relation to the thigh. Hamstring injuries are common among athletes, especially in sports like soccer with sprinting demands, kicking, and sudden accelerations. Hamstring strains are frustrating for the injured athletes because the symptoms are persistent, healing is slow, and the rate of re-injury is high. This indicates a need to develop prevention strategies for hamstring injuries. The aims of this review are introducing hamstring strains, associated risk factors, and providing rehabilitative ecommendations for injured athletes to prevent re-injury. METHOD: Information was gathered from an online literatures search using the key words hamstring injuries, soccer injuries, injury prevention, hamstring rehabilitation, and stretching exercises. Screening of references and hand searches of relevant journals were also employed. All relevant studies in English were reviewed and abstracted.RESULTS: It has been shown that hamstring strains account for 12-16% of all injuries in athletes with a re-injury rate reported as high as 22-34%. The hamstrings have a tendency to shorten. Tight hamstrings with limited range of motion and flexibility may lead to postural deficiency and deformities. It also makes the hamstring susceptible to re-injury. Risk factors such as age, strength imbalance, previous injury and flexibility should be considered. CONCLUSION: Prevention intervention may minimize the risk factors of hamstring injuries. Training modalities should emphasize on eccentric strength training, and prevention of fatigue. There is wide disagreement about the impact of stretching exercise on prevention/rehabilitation of hamstring injuries.

    Our study examines a recreational curling population to describe patterns of injury occurrence, estimate risk of injury and to gauge attitudes towards equipment-based prevention strategies. In a retrospective case series, we queried the Canadian Hospitals Injury Reporting and Prevention Program (CHIRPP), a national injury surveillance database, for curling injuries entered between 1993 and 2011. Kingston General Hospital and Hotel Dieu Hospital provide the two Kingston, Ontario, sites for emergency department (ED) care and participate in CHIRPP. Each retrieved entry underwent a chart review. A secondary survey was mailed to select individuals who had experienced curling injuries to solicit details on their injury and attitudes towards equipment to prevent injury. We used descriptive statistics for rates and proportions. Over 90% of acute curling injuries resulted from a fall, and 31.7% were head impacts. We found that acute injuries requiring ED presentation occur at a rate of approximately 0.17 per 1000 athlete-exposures (95% CI: 0.12-0.22). The secondary survey was completed by 54% of potential respondents. Of survey respondents, 41.3% attributed their fall to a lack of proper footwear and 73.5% of respondents agreed with mandatory sport-specific footwear as a prevention strategy, but only 8% agreed with mandatory helmet wear. Although curling injuries requiring medical care are not common, head injuries make up a large proportion. Mandated use of appropriate footwear appears to be the most effective prevention strategy, as well as the measure deemed most acceptable by players.

    Prevention of anterior cruciate ligament (ACL) injury is likely the most effective strategy to reduce undesired health consequences including reconstruction surgery, long-term rehabilitation, and pre-mature osteoarthritis occurrence. A thorough understanding of mechanisms and risk factors of ACL injury is crucial to develop effective prevention programs, especially for biomechanical and neuromuscular modifiable risk factors. Historically, the available evidence regarding ACL risk factors has mainly involved female athletes or has compared male and female athletes without an intra-group comparison for male athletes. Therefore, the principal purpose of this article was to review existing evidence regarding the investigation of biomechanical and neuromuscular characteristics that may imply aberrant knee kinematics and kinetics that would place the male athlete at risk of ACL injury. Biomechanical evidence related to knee kinematics and kinetics was reviewed by different planes (sagittal and frontal/coronal), tasks (single-leg landing and cutting), situation (anticipated and unanticipated), foot positioning, playing surface, and fatigued status. Neuromuscular evidence potentially related to ACL injury was reviewed. Recommendations for prevention programs for ACL injuries in male athletes were developed based on the synthesis of the biomechanical and neuromuscular characteristics. The recommendations suggest performing exercises with multi-plane biomechanical components including single-leg maneuvers in dynamic movements, reaction to and decision making in unexpected situations, appropriate foot positioning, and consideration of playing surface condition, as well as enhancing neuromuscular aspects such as fatigue, proprioception, muscle activation, and inter-joint coordination.

    Aim: To evaluate the effectiveness of a novel injection technique in the management of recalcitrant medial collateral ligament (MCL) injuries of the knee. Materials and methods: The injection, comprising 10 ml local anaesthetic with 25–50 mg hydrocortisone, is directed beneath the periosteal attachment of the MCL. Twenty-eight patients who received the intervention were asked to complete a questionnaire, a visual analogue scale (VAS) and the International Knee Documentation Committee (IKDC) subjective knee form to quantify symptoms pre-injection and at follow-up. Data were assessed using descriptive statistics. Further analysis was conducted using the Wilcoxon signed-rank test and Fisher's exact test. Results: Sixty-eight percent (n = 19) of patients responded. Three patients were excluded according to the exclusion criteria. Of those studied, 37.5% (n = 6) were professional athletes. At follow-up, patients reported a mean improvement on the VAS of 75.5% (SD = 23.6). There was a significant improvement in IKDC scores (mean difference 42%, SD = 14.2) pre- and post-injection (Wilcoxon signed-rank test, p < 0.001). No residual symptoms were reported by 50% (n = 8) of patients, and a further 37.5% (n = 6) of patients had improved. Of those patients who played sport, two-thirds (n = 10) had returned to their previous level of sport at follow-up, including all of the professional athletes. Conclusion: Periosteal high-volume image-guided injection is a useful treatment for recalcitrant MCL injury. Results are encouraging, particularly amongst the professional athletes studied

    Injury prevention is an important issue for police officers, but the effectiveness of prevention initiatives is dependent on officers' motivation toward, and adherence to, recommended health and safety guidelines. To understand effects of police officers' motivation to prevent occupational injury on beliefs about safety and adherence to injury prevention behaviours. Full-time police officers completed a survey comprising validated psychometric scales to assess autonomous, controlled and amotivated forms of motivation (Treatment Self-Regulation Questionnaire), behavioural adherence (Self-reported Treatment Adherence Scale) and beliefs (Safety Attitude Questionnaire) with respect to injury prevention behaviours. There were 207 participants; response rate was 87%. Hierarchical multiple regression analyses demonstrated that autonomous motivation was positively related to behavioural adherence, commitment to safety and prioritizing injury prevention. Controlled motivation was a positive predictor of safety communication barriers. Amotivation was positively associated with fatalism regarding injury prevention, safety violation and worry. These findings are consistent with the tenets of self-determination theory in that autonomous motivation was a positive predictor of adaptive safety beliefs and adherence to injury prevention behaviours. © The Author 2017.

    dorsiflexion of the ankle when performing sport tasks, lateral trunk displacement and hip adduction combined with increased knee abduction moments (dynamic knee valgus), and increased hip internal rotation and tibial external rotation with or without foot pronation. The identified mechanisms and risk factors for non-contact ACL injuries have been mainly studied in female soccer players; thus, further research in male players is warranted. Non-contact ACL injuries in soccer players likely has a multi-factorial etiology. The identification of those athletes at increased risk may be a salient first step before designing and implementing specific pre-season and in-season training programs aimed to modify the identified risk factors and to decrease ACL injury rates. Current evidence indicates that this crucial step to prevent ACL injury is the only option to effectively prevent the sequelae of osteoarthritis associated with this traumatic injury.

    We examined the effects of a 12-week program of Nordic hamstring exercises (NHE), administered before or after football training, upon eccentric hamstring strength, muscle activity, and architectural adaptations. Amateur soccer players were randomized into three groups. The control group (CON; n=11) undertook core stability exercises, whereas a periodized NHE program was delivered either before (NHE BEF ; n=10) or after (NHE AFT ; n=14) biweekly training sessions. Outcome measures included peak torque and concomitant normalized peak surface electromyography signals (sEMG) of the biceps femoris (BF) and medial hamstring (MH) muscles during knee flexor maximal eccentric contractions, performed at 30°·s -1 . Ultrasonography was used to determine BF muscle thickness, muscle fiber pennation angle, and fascicle length. Performing the NHE derived likely moderate peak torque increases in both NHE BEF (+11.9%; 90% confidence interval: 3.6%-20.9%) and NHE AFT (+11.6%; 2.6%-21.5%) vs CON. Maximum sEMG increases were moderately greater in the BF of both NHE training groups vs CON. There were likely moderate increases in BF muscle thickness (+0.17 cm; 0.05-0.29 cm) and likely small pennation angle increases (+1.03°; -0.08° to 2.14°) in NHE AFT vs CON and NHE BEF . BF fascicle length increases were likely greater in NHE BEF (+1.58 cm; 0.48-2.68 cm; small effect) vs CON and NHE AFT . A 12-week eccentric hamstring strengthening program increased strength and sEMG to a similar magnitude irrespective of its scheduling relative to the football training session. However, architectural adaptations to support the strength gains differed according to the timing of the injury prevention program. © 2017 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    Elastic bandages are commonly used in sports to treat and prevent sport injuries. To conduct a systematic review assessing the effectiveness of elastic bandaging in orthopedic- and sports-injury prevention and rehabilitation. The researchers searched the electronic databases MEDLINE, CINAHL, SPORTDiscus, EMBASE, and Physiotherapy Evidence Database (PEDro) with keywords elastic bandaging in combination, respectively, with first aid, sports injuries, orthopedic injuries, and sports injuries prevention and rehabilitation. Research studies were selected based on the use of the term elastic bandaging in the abstract. Final selection was made by applying inclusion and exclusion criteria to the full text. Studies were included if they were peer-reviewed clinical trials written in English on the effects of elastic bandaging for orthopedic-injury prevention and rehabilitation. Twelve studies met the criteria and were included in the final analysis. Data collected included number of participants, condition being treated, treatment used, control group, outcome measures, and results. Studies were critically analyzed using the PEDro scale. The studies in this review fell into 2 categories: studies in athletes (n = 2) and nonathletes (n = 10). All included trials had moderate to high quality, scoring ≥5 on the PEDro scale. The PEDro scores for the studies in athletes and nonathletes ranged from 5 to 6 out of 10 and from 5 to 8 out of 10, respectively. The quality of studies was mixed, ranging from higher- to moderate-quality methodological clinical trials. Overall, elastic bandaging can assist proprioceptive function of knee and ankle joint. Because of the moderate methodological quality and insufficient number of clinical trials, further effects of elastic bandaging could not be confirmed.

  20. [Skiing injuries in school sport and possibilioties to prevent them].

    Science.gov (United States)

    2011-12-01

    Tyrol (Austria) is one of the regions which pioneered skiing. Skiing is considered as a national sport and is deeply rooted within the school system. Thus most pupils partake in skiing courses in this period. It is clear that such a large group of pupils also leads to a significant number of skiing injuries. Preventive issues may be derived from an analysis of the pattern and circumstances of skiing injuries. During a period of ten years (2000 - 2009) 1522 school sports injuries have been reported to the health insurance agency (Allgemeine Unfallversicherungsanstalt) from all secondary schools in Tyrol. The major disciplines were ski (48 %, n = 734) ice skateing (23 %, n = 349) and snowboard injuries (21 %, n = 315), followed by tobogganing (6 %, n = 91), cross-country skiing (1 %, n = 17) and other wintersports (1 %, n = 16). Fractures (31 %) dominated in skiing, followed by contusions (23 %), and sprains (22 %). In the analysis of the distribution of injuries during alpine skiing accidents, lower extremity injuries (39 %) dominated followed by upper extremity injuries (34 %). Head and spine injuries (13 %) were rare. Analysing the circumstances of the injuries, most injuries during skiing occurred without person to person collision (82 %), 81 % either shortly before lunch-break or in the afternoon. Skiing injuries account for a significant proportion of all school sport-related injuries in Tyrol. Lower extremity injuries account for the vast majority of all injuries. Overestimation and overtiredness may be responsible for skiing sport injuries. Preventive measures such as a fitness training (e. g., skiing exercises) prior to skiing courses, appropriate breaks and proper protective gear (i. e., helmet and spine protector) may reduce the injury rate in skiing school sport. © Georg Thieme Verlag KG Stuttgart · New York.

    2015-03-01

    Mechanical prophylaxis with foot-pumps provides an interesting alternative to chemical agents in the prevention of venous thomboembolism following major orthopaedic surgery procedures. The aim of this prospective study was to assess efficacy and safety of the Flowtron(®) foot-pumps system following total hip and knee replacement. The foot pumps were used as main tool for prevention of thromboembolic events, in most cases in association with a variety of chemicals. The primary endpoint of the study was to assess the incidence of deep vein thrombosis and pulmonary embolism after total hip and knee replacement. The secondary endpoints included postoperative bleeding, swelling, bruising and wound ooze. 424 consecutive patients were included in the study. Symptomatic deep vein thrombosis was detected in 7 patients (1.6%). All symptomatic deep vein thromboses were detected after discharge before the six week follow-up clinic. Five non-fatal pulmonary embolisms occurred (1.2%). Only one patient presented a major wound bleeding (0.2%). The mean difference of swelling of thigh pre-versus postoperatively was only 22.8 mm. In conclusion, thromboembolism prophylaxis after total hip and knee replacement using Flowtron(®) foot-pumps as main prevention tool of an individualised protocol appears effective and safe. This is the first clinical report related to this popular brand of foot pumps.

    Instability of the knee after the medial collateral ligament (MCL) injury is usually assessed with the manual valgus stress test, even though, in recent years, it has become possible to apply magnetic resonance imaging (MRI) to the assessment of the damage of the ligament. The valgus instability of 24 patients (12 isolated injuries and 12 multiple ligament injuries) who suffered MCL injury between 1993 and 1998 was evaluated with the Hughston and Eilers classification, which involves radiographic assessment under manual valgus stress to the injured knees. We developed a novel system for classifying the degree of injury to the MCL by calculating the percentage of injured area based on MRI and investigated the relationship between this novel MRI classification and the magnitude of valgus instability by the Hughston and Eilers classification. There was a significant correlation between the 2 classifications (p=0.0006). On the other hand, the results using other MRI based classification systems, such as the Mink and Deutsch classification and the Petermann classification, were not correlated with the findings by the Hughston and Eilers classification in these cases (p>0.05). Since MRI is capable of assessing the injured ligament in clinical practice, this novel classification system would be useful for evaluating the stability of the knee and choosing an appropriate treatment following MCL injury.

  6. Pediatric unintentional injury: behavioral risk factors and implications for prevention.

    2007-06-01

    Unintentional injury is the leading cause of death for children and adolescents between the ages of 1 and 18 in the United States, accounting for more deaths than the next 20 causes of mortality combined. It is estimated that pediatric injury accounts for more than $50 billion in annual losses from medical care costs, future wages, and quality of life. Despite these numbers, much remains to be learned about the behavioral risks for pediatric unintentional injury. This article reviews behavioral risk factors for pediatric unintentional injury risk, with a particular focus on four broad areas. First, we discuss the effects of demographic risk factors, including gender, socioeconomic status, and ethnicity. Second, we present information about child-specific risk factors, including temperament, personality, psychopathology, and cognitive development. Third, we discuss the influence of parents and other primary caregivers on childhood injury risk, with a particular focus on the effects of supervision and parenting quality and style. Finally, we discuss the role of peers on child injury risk. We conclude with a discussion of the ways in which the material reviewed has been translated into injury prevention techniques, with a focus on how pediatricians might use knowledge about etiological risk to prioritize safety counseling topics. We also present thoughts on four priorities for future research: injury risk in diverse nations and cultures; developmental effects of injury; the influence of multiple risk factors together on injury risk; and translation of knowledge about risk for injury into intervention and prevention techniques.

    Our purpose was to evaluate the effectiveness of intra-articular injections of hyaluronic acid (HA) into immobilized joints for reducing rigidity and formation of joint adhesions following surgery and prolonged joint immobilization. Twenty-four New Zealand white rabbits were randomly divided into experimental (n = 12) and control groups (n = 12). A model of knee injury was created in the right hind leg, and external plaster fixation was performed for 8 weeks. The experimental and control groups received weekly intra-articular injections of 0.3 mL HA solution or normal saline, respectively, in the knee joint. The degree of adhesions, range of motion (ROM), and collagen content of the synovium of the knee joint were observed after 8 weeks. At the end of 8 weeks, the experimental compared with control group had significantly higher mean ROM (70.3° ± 11.1° vs. 54.6° ± 11.2°, respectively; P = 0.002) and mean adhesion score. The experimental group compared with the control group had significantly lower mean adhesion score (2.2 ± 0.9 vs. 3.1 ± 0.7, respectively; P = 0.012) and collagen content (32.4 ± 4.7 vs. 39.0 ± 4.2 μg/mg, P = 0.001). In a rabbit model of knee injury, intra-articular injection of HA decreased adhesion formation and collagen content and increased ROM after prolonged immobilization. These results indicate that HA may be clinically useful to prevent adhesions and improve joint mobility in patients who require joint immobilization for up to 8 weeks.

    To describe the pathological appearance of the anterolateral ligament (ALL) on US and MRI in knees with an anterior cruciate ligament (ACL) tear. This prospective study included 30 patients who had a suspected acute ACL tear. Their injured and contralateral knees were evaluated with radiography, US and MRI. Two radiologists evaluated the ALL on the MRI and US examinations. Agreement between these examiners' findings was evaluated with Cohen's kappa. On US examination, the ALL was found to be injured in 63% of cases (19/30; k = 0.93). The enthesis was found to be torn in 50% of cases (15/30; k = 1), with the tear located at the tibial attachment in all instances. On the MRI exam, the ALL was found to be injured in 53% of cases (16/30; k = 0.93). The enthesis was found to be torn in 13% of cases (4/30; k = 0.76), with the tear located at the tibial attachment in all instances (k = 0.93). ALL injuries that occur with ACL tears are located at the tibial enthesis. They are often associated with bone avulsion at the enthesis and are better viewed on US. (orig.)

    2000-10-01

    Franklin County Home Health Agency (St Albans, Vermont) undertook a performance improvement project in 1996 to reduce employee injuries. A review of recent injuries led to the prevention of licensed nursing assistants' (LNAs') back and shoulder injuries as the first priority. Root causes of injuries were agency communication, employee training, patient home environment, nursing assistant body mechanics, and failure to use safety measures. Given that injury causality is complex and multifactorial, a variety of improvement strategies were implemented over the following two to three years. IMPLEMENTATION OF POTENTIAL SOLUTIONS: Short-term (a few months), mid-term (six months), and long-term (one year) potential solutions to the LNA back and shoulder injury problem were charted. Safety and health training was the major focus of the team's short-term plan. Risk management forms were to be used to identify and follow up on hazardous situations. Project plans that were successfully implemented included revision of LNA plans of care, standardization of the return-to-work process after injury, development of guidelines for identifying unsafe patient lifts and transfers, improved follow-up of employee reports of injury-risk situations in patient homes, improved body mechanics screening of new employees, and a stronger injury-prevention training program for current employees. A less successful initiative was aimed at collecting more data about injuries and causal factors. Employee injuries were gradually reduced from 4-10 per quarter to 0-3 per quarter. Injury prevention requires commitment, persistence, and patience--but not expensive improvements. Multiple interventions increase the chances of success when there are many root causes and lack of evidence regarding the effectiveness of various approaches.

  17. Preventing unintentional injury in children and adolescents--the importance of local injury data collection.

    2012-02-01

    We sought to prospectively study all injuries in children and adolescents up to 16 years of age presenting to a regional Emergency Department (ED), to ascertain detailed injury patterns and to use this data to recommend injury prevention priorities. Electronic injury surveillance was prospectively collected over a 10 year period (1997-2007) in a hospital with a paediatric catchment population of 75,000 in a region with pockets of high social deprivation. All fatalities were obtained from data provided by the Central Statistics Office (CSO). Over a 10 year period, there were 31 fatalities, 5,408 admissions and 40,817 new attendances due to injury. Males outnumbered females in a 3:2 ratio. Of all injuries 24,317 (60%) occurred at home. Peak injury presentation time was in the evening between 18:00 and 20:00. Minor injuries (bruises, minor head injuries, lacerations and sprains) accounted for 32,456 (80%) of total. Fractures resulting from high falls (n=1,194) tended to result from bunk beds, staircases, horses, walls and playground equipment. Burns (n=630) involved hot liquids (tea, coffee), hot bath water, hot cooking oil and hot cooking plates. Pedestrian injuries (n=251) were predominantly \\'dart outs\\' in urban areas. Car passenger injuries (n=869) showed low rates of documented car restraint use. Poisonings (n= 1,153) were predominantly medicinal products. Cyclist injuries (n=477) indicated low documented use of appropriate helmet wear. Prevention priorities should focus on home injuries, hot liquid burn and scald injuries and high falls from walls, beds and playground equipment. To prevent road-related injuries and deaths, further legislation, urban planning and greater police enforcement is required.

    The unique quality of the bicycle is its ability to accommodate a wide variety of injuries and disabilities. Cycling for recreation, transportation, and competition is growing nationwide, and has proven health and societal benefits. The demands of each type of cycling dictate the necessary equipment, as well as potential for injury. Prevention of cycling-related injury in both the athlete and the recreational cyclist involves understanding the common mechanisms for both traumatic and overuse injury, and early correction of strength and flexibility imbalances, technique errors, and bicycle fit.

    OSHA's enforcement program is one of the major public efforts to protect American workers. We examine both the scope of injury prevention that inspections can contribute and the types of standards that contribute the most. We linked Pennsylvania Department of Labor and Industry files for lost-time injuries and employment to calculate injury rates for 1998-2005 for all single-establishment manufacturing firms. We linked these to OSHA inspection records. Inspections with penalties did affect injury types unrelated to standards as well as those related. We also found again that citations for violations of the standard requiring personal protective equipment had the largest impact on preventing injuries. Programs requiring protective equipment use deserve added attention from consultants and inspectors. In addition, some inspections spur managers to undertake safety measures that go beyond compliance with standards. 2010 Elsevier Ltd. All rights reserved.

    Full Text Available Introduction: Our study examines a recreational curling population to describe patterns of injury occurrence, estimate risk of injury and to gauge attitudes towards equipment-based prevention strategies. Methods: In a retrospective case series, we queried the Canadian Hospitals Injury Reporting and Prevention Program (CHIRPP, a national injury surveillance database, for curling injuries entered between 1993 and 2011. Kingston General Hospital and Hotel Dieu Hospital provide the two Kingston, Ontario, sites for emergency department (ED care and participate in CHIRPP. Each retrieved entry underwent a chart review. A secondary survey was mailed to select individuals who had experienced curling injuries to solicit details on their injury and attitudes towards equipment to prevent injury. We used descriptive statistics for rates and proportions. Results: Over 90% of acute curling injuries resulted from a fall, and 31.7% were head impacts. We found that acute injuries requiring ED presentation occur at a rate of approximately 0.17 per 1000 athlete-exposures (95% CI: 0.12–0.22. The secondary survey was completed by 54% of potential respondents. Of survey respondents, 41.3% attributed their fall to a lack of proper footwear and 73.5% of respondents agreed with mandatory sport-specific footwear as a prevention strategy, but only 8% agreed with mandatory helmet wear. Conclusions: Although curling injuries requiring medical care are not common, head injuries make up a large proportion. Mandated use of appropriate footwear appears to be the most effective prevention strategy, as well as the measure deemed most acceptable by players.

    Complex pelvic ring fracture associated with floating knee is comparatively rare which usually results from high-energy trauma including vehicle-related accidence, falls from height, and earthquake-related injury. To our knowledge, few literatures have documented such injuries in the individual patient. Management of both injuries present challenges for surgical management and postoperative care. The purpose of this study is to prove the feasibility and benefits of damage control orthopedics (DCO). Our case involved a 45-year-old lady who was hit by a dilapidated building. The patient was anxious, pale and hemodynamically stable at the initial examination. The pelvis was unstable and there were obvious deformities in the left lower extremities. Significant degloved injuries in the left leg were noted. Her radiographs and physical examination verified the above signs. Unstable pelvic fractures, multiple fractures of bilateral lower limbs with floating knee injury, multiple pelvic and rib fractures and multiple degloving injuries and soft tissue contusion formed the characteristics of the multiple-injury. The algorithm of DCO was determined as the treatment. Early simplified procedures such as wound debridement, pelvis fixation, closed reduction and EF of the right shoulder joint, and chest wall fixation were conducted as soon as possible. After a period of time, internal fixations were applied to the fracture sites. The subsequent functional exercise was also conducted in accordance with this algorithm. This patient got recovery after the treatments which were guided by the criterion of DCO. The restoration of limb functional and the quality of life greatly improved. The DCO plays a decisive role in the first aid and follow-up treatment of this patient. The guidelines of management of complex pelvic ring injuries and floating knee should be established by authorities.

    Atrial fibrillation remains the most common arrhythmia worldwide, with pulmonary vein isolation (PVI) being an essential component in the treatment of this arrhythmia. In view of the close proximity of the oesophagus with the posterior wall of the left atrium, oesophageal injury prevention has become a major concern during PVI procedures. Oesophageal changes varying from erythema to fistulas have been reported, with atrio-oesophageal fistulas being the most feared as they are associated with major morbidity and mortality. This review article provides a detailed description of the risk factors associated with oesophageal injury during ablation, along with an overview of the currently available techniques to prevent oesophageal injury. We expect that this state of the art review will deliver the tools to help electrophysiologists prevent potential oesophageal injuries, as well as increase the focus on research areas in which evidence is lacking.

    Full Text Available Abstract Background Hamstring injury is one of the most common injuries affecting gaelic footballers, similar to other field sports. Research in other sports on whether residual hamstring weakness is present after hamstring injury is inconsistent, and no study has examined this factor in irish gaelic footballers. The aim of this study was to examine whether significant knee muscle weakness is present in male Irish gaelic footballers who have returned to full activity after hamstring injury. Methods The concentric isokinetic knee flexion and extension strength of 44 members of a university gaelic football team was assessed at 60, 180 and 300 degrees per second using a Contrex dynamometer. Results Fifteen players (34% reported a history of hamstring strain, with 68% of injuries affecting the dominant (kicking limb. The hamstrings were significantly stronger (p 0.05 using this comparison. The previously unilaterally injured hamstrings were significantly weaker (p Conclusion Hamstring muscle weakness was observed in male Irish gaelic footballers with a history of hamstring injury. This weakness is most evident when comparisons are made to multiple control populations, both within and between subjects. The increased strength of the dominant limb should be considered as a potential confounding variable in future trials. The study design does not allow interpretation of whether these changes in strength were present before or after injury.

    The most common joint injuries in professional and recreational sports participants and also in the total population are knee injuries. Arthroscopy is indicated if this modality will improve the patient outcome and potential long-term complications can be avoided. Although uncommon, complications following arthroscopy are mostly evaluated by magnetic resonance imaging (MRI). For planning further therapy strategies following postarthroscopic complications, e.g. if anterior cruciate ligament (ACL) reconstruction is required, digital radiographs and computed tomography (CT) are helpful. This article provides an overview of the different procedures for surgical treatment which are a prerequisite for the analysis of postarthroscopic images. In addition typical complications after treatment of meniscal and chondral injuries as well as after ACL reconstruction are described and typical signs in MRI, radiography and CT are explained in detail.

    Many aspects of perinatal nursing put nurses at risk for injuries, including frequent repetitive bending, lifting of clients, and exposure to potentially large amounts of body fluids such as blood and amniotic fluid. Violence is also a potential risk with stressful family situations that may arise around childbirth. Workplace injuries put a health care facility at risk for staff turnover, decreases in the number of skilled nurses, client dissatisfaction, workers' compensation payouts, and employee lawsuits. Through the use of safety equipment, improved safety and violence training programs, "no manual lift" policies, reinforcement of personal protective equipment usage, and diligent staff training to improve awareness, these risks can be minimized. © 2016 AWHONN, the Association of Women’s Health, Obstetric and Neonatal Nurses.

    High levels of youth employment, workplace hazards, and characteristics unique to adolescents contribute to a relatively high incidence of injuries among teens in the restaurant industry. This article discusses the ProSafety model of injury prevention among teen restaurant workers. Through integration with an existing career and technical education program, the ProSafety project seeks to prevent occupational injuries among the teen worker population through classroom safety education and internship skills reinforcement. ProSafety is the product of an innovative collaboration with occupational health nurses, business professionals, educators, and government. Its approach is derived from Social Cognitive Theory, is consistent with key values and strategies of occupational health nurses, and provides lessons for practitioners seeking to reduce occupational injuries in food service or among other populations of adolescent workers.

    Study Design Prospective cohort. Background The high risk of second anterior cruciate ligament (ACL) injuries after return to sport highlights the importance of return-to-sport decision making. Objective return-to-sport criteria frequently use limb symmetry indexes (LSIs) to quantify quadriceps strength and hop scores. Whether using the uninvolved limb in LSIs is optimal is unknown. Objectives To evaluate the uninvolved limb as a reference standard for LSIs utilized in return-to-sport testing and its relationship with second ACL injury rates. Methods Seventy athletes completed quadriceps strength and 4 single-leg hop tests before anterior cruciate ligament reconstruction (ACLR) and 6 months after ACLR. Limb symmetry indexes for each test compared involved-limb measures at 6 months to uninvolved-limb measures at 6 months. Estimated preinjury capacity (EPIC) levels for each test compared involved-limb measures at 6 months to uninvolved-limb measures before ACLR. Second ACL injuries were tracked for a minimum follow-up of 2 years after ACLR. Results Forty (57.1%) patients achieved 90% LSIs for quadriceps strength and all hop tests. Only 20 (28.6%) patients met 90% EPIC levels (comparing the involved limb at 6 months after ACLR to the uninvolved limb before ACLR) for quadriceps strength and all hop tests. Twenty-four (34.3%) patients who achieved 90% LSIs for all measures 6 months after ACLR did not achieve 90% EPIC levels for all measures. Estimated preinjury capacity levels were more sensitive than LSIs in predicting second ACL injuries (LSIs, 0.273; 95% confidence interval [CI]: 0.010, 0.566 and EPIC, 0.818; 95% CI: 0.523, 0.949). Conclusion Limb symmetry indexes frequently overestimate knee function after ACLR and may be related to second ACL injury risk. These findings raise concern about whether the variable ACL return-to-sport criteria utilized in current clinical practice are stringent enough to achieve safe and successful return to sport.

    Full Text Available INTRODUCTION: This study aimed to cross-culturally adapt a Malay version of Knee Injury and Osteoarthritis Outcome Score (KOOS and to evaluate its psychometric properties in patients with knee osteoarthritis (OA. MATERIALS AND METHODS: The English version KOOS was translated into a Malay version using forward and backward translation process, followed by face validity and content validity. Two hundred and twenty-six knee OA patients attending the Outpatient and Orthopaedic Clinics, Universiti Sains Malaysia Hospital, completed the Malay version KOOS. Construct validity using confirmatory factor analysis and internal reliability assessment were performed. RESULTS: The results showed that the original five-factor model with 42 items failed to achieve acceptable values of the goodness of fit indices, indicating poor model fit. A new five-factor model of 26 items demonstrated acceptable level of goodness of fit (comparative fit index= 0.929, incremental fit index= 0.930, Tucker Lewis fit index= 0.920, root mean square error of approximation= 0.073 and Chisquared/ degree of freedom= 2.183 indices to signify a model fit. The Cronbach’s alpha value for the new model ranged from 0.776 to 0.946. The composite reliability values of each construct ranged between 0.819 and 0.921, indicating satisfactory to high level of convergent validity. CONCLUSION: The five-factor model with 26 items in the Malay version of KOOS questionnaire demonstrated a good degree of goodness of fit and was found to be valid, reliable and simple as an assessment tool for symptoms, pain, activity of daily living, sports and recreational activity and quality of life for Malaysian adults suffering from knee osteoarthritis.

    Full Text Available Introduction: the arthritis is believed to be among common diseases which prevail in the developed and developing countries, including Iran. In demographic studies, the prevalence of knee arthritis which stands at %15/3 in the population above 15-years old was shown. Owing to the fact that societies are about to be aged than before, the issue has become a growing significance in the subject matter of public health. The present study is conducted with an aim to investigate into the effect of training based on the planned behavior model on preventing the teachers of preliminary schools from getting knee arthritis. Methods: the study as an intervention research is of quasi-experimental kind. The population in question included 114 individuals among female teachers of preliminary schools who were brought to the study randomly and divided into two groups intervention and non-intervention. Based on the primary results, the educational contents were designed and submitted in the intervention group. After two months of executing the training program, the post test was carried out. The data was analyzed by SPSS version 18. Due to the loss of normality in data distribution, non- parametric tests were used. Results: the study demonstrated that the components of the planned behavior theory (i.e. the attitudes, subjective norms and the control of perceived behavior could altogether estimate %37 of intention and %43 of behavior. Meanwhile, the role of subjective norms (β =56/0 in predicting intention was overriding, In this study,after the educational program, control of perceived behavior scores increased of 32/50 ± 4/05 to 34/82 ± 5/66. indicating that the major obstacles in adopting behaviors preventing from knee arthritis are the lack of regular physical activity (%72/4 and failure to use western-style toilet (%57.

    Hand injuries are a frequent occurrence and account for 41% of all occupational injuries. In general such accidents are the result of stress, inattention, tiredness, use of defective or poorly maintained machinery. However, artention must equally be directed at the large number of accidents occurring in leisure time activities since the inability to work due to a leisure time accident is similarly cost-intensive. Throughout Europe attempts have been made in the past 10 years to improve prevention. At the initiative of the Hand Trauma Committee (HTC) of FESSH prevention conferences were stated in 2009. These have in part reduced the number of hand injuries in -Europe. In Austria a special controlling committee was founded by the Austrian Workers' Compensation Board (AUVA) with the specific objective of reducing the number of hand injuries. Similarly the "Circle for Leisure Time Hand Injury Prevention" was created to specifically deal with hand injuries occurring during leisure time activities. Through the cooperation of these 2 committees and implementation of the thus decided measures, a reduction in the number of accidents involving the hand is to be expected with a concomitant reduction in the associated costs. © Georg Thieme Verlag KG Stuttgart · New York.

    Single limb stance instability is a risk factor for lower extremity injuries. Therefore, the development of proprioception may play an important role in injury prevention. This investigation considered a professional basketball team for 6 years, integrating systematic proprioceptive activity in the training routine. The purpose was to assess the effectiveness of proprioceptive training programs based on quantifiable instability, to reduce ankle sprains, knee sprains, and low back pain through developing refined and long-lasting proprioceptive control. Fifty-five subjects were studied. In the first biennium (2004-2006), the preventive program consisted of classic proprioceptive exercises. In the second biennium (2006-2008), the proprioceptive training became quantifiable and interactive by means of electronic proprioceptive stations. In the third biennium (2008-2010), the intensity and the training volume increased while the session duration became shorter. Analysis of variance was used to analyze the differences in proprioceptive control between groups, years, and bienniums. Injury rates and rate ratios of injury during practices and games were estimated. The results showed a statistically significant reduction in the occurrence of ankle sprains by 81% from the first to the third biennium (p < 0.001). Low back pain showed similar results with a reduction of 77.8% (p < 0.005). The reduction in knee sprains was 64.5% (not significant). Comparing the third biennium with the level of all new entry players, proprioceptive control improved significantly by 72.2% (p < 0.001). These findings indicate that improvements in proprioceptive control in single stance may be a key factor for an effective reduction in ankle sprains, knee sprains, and low back pain.

    Aim of the study was to access how individual's motives for participation in sports impact on self-reported outcomes 2 years after an anterior cruciate ligament injury. Based on a longitudinal cohort study, this secondary analysis present data from the Knee Anterior Cruciate Ligament, Nonsurgical versus Surgical Treatment (KANON) study, a randomized controlled trial. At baseline, 121 patients recorded in an initial questionnaire that their motives for sports participation fell into four categories: achievement, health, social integration, or fun and well-being. These four categories were used as variables in the analyses. All 121 subjects completed the 2-year follow-up. The largest improvement was seen in the Knee Injury and Osteoarthritis Outcome Score (KOOS) subscale sports and recreation function, with an effect size of 2.43. KOOS sports and recreation function was also the subscale score best predicted by the motives for sports participation. Baseline motives achievement and fun and well-being predicted worse levels of pain and function 2 years after the injury, even after adjusting for age, gender, treatment and baseline scores. Psychological aspects, such as motives for participation in sport, can be factors in predicting of patient-reported outcomes 2 years after injury. Evaluating motives for sports participation may help predict the outcome 2 years after ACL injury. © 2014 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    Background The incidence rate of soccer injuries is among the highest in sports, particularly for adult male soccer players. Purpose To investigate the effect of the ‘The11’ injury prevention programme on injury incidence and injury severity in adult male amateur soccer players. Study design Cluster-randomised controlled trial. Methods Teams from two high-level amateur soccer competitions were randomly assigned to an intervention (n=11 teams, 223 players) or control group (n=12 teams, 233 players). The intervention group was instructed to perform The11 in each practice session during one soccer season. The11 focuses on core stability, eccentric training of thigh muscles, proprioceptive training, dynamic stabilisation and plyometrics with straight leg alignment. All participants of the control group continued their practice sessions as usual. Results In total, 427 injuries were recorded, affecting 274 of 456 players (60.1%). Compliance with the intervention programme was good (team compliance=73%, player compliance=71%). Contrary to the hypothesis, injury incidences were almost equal between the two study groups: 9.6 per 1000 sports hours (8.4–11.0) for the intervention group and 9.7 (8.5–11.1) for the control group. No significant differences were found in injury severity, but a significant difference was observed in the location of the injuries: players in the intervention group sustained significantly less knee injuries. Conclusions This study did not find significant differences in the overall injury incidence or injury severity between the intervention and control group of adult male soccer players. More research is recommended, focusing on injury aetiology and risk factors in adult male amateur soccer players. PMID:22878257

    Despite increased knowledge of hamstring muscle injuries, the incidence has not diminished. We now know that not all hamstring injuries are the same and that certain types of injuries require prolonged rehabilitation and return to play. The slow stretch type of injury and injuries involving the central tendon both require longer times to return to play. A number of factors have been proposed as being indicators of time taken to return to play, but the evidence for these is conflicting. Recurrence rates remain high and it is now thought that strength deficits may be an important factor. Strengthening exercise should be performed with the hamstrings in a lengthened position. There is conflicting evidence regarding the efficacy of platelet-rich plasma injection in the treatment of hamstring injuries so at this stage we cannot advise their use. Various tests have been proposed as predictors of hamstring injury and the use of the Nordboard is an interesting addition to the testing process. Prevention of these injuries is the ultimate aim and there is increasing evidence that Nordic hamstring exercises are effective in reducing the incidence. PMID:26105015

    Injuries and violence impact millions across the globe each year. For the past 20 years, the National Center for Injury Prevention and Control (NCIPC) at the Centers for Disease Control and Prevention (CDC) has assembled the largest cadre of injury and violence prevention experts in the world to reduce the burden of injuries and violence domestically and to inform global injury and violence prevention efforts. This article focuses on NCIPC's global injury and violence prevention work that involves: increasing awareness of the preventability of injury and violence, partnerships to promote injury research and best practices; establishing standards and guidance for data collection; building capacity through training and mentoring; and supporting evidence-based strategies. To decrease the global burden, the authors propose priority setting to maximize the development and sustainability of financial and human resources for injury and violence prevention. The authors call for increased capacity and resources for global injury and violence prevention. Published by Elsevier Ltd.

    The most recent report on hospital-treated horse-riding injuries in Victoria was published 20 years ago. Since then, injury countermeasures and new technology have aimed to make horse riding safer for participants. This study provides an update of horse-riding injuries that required hospital treatment in Victoria and examines changes in injury patterns compared with the earlier study. Horse-riding injuries that required hospital treatment (hospital admission (HA) or emergency department (ED) presentations) were extracted from routinely collected data from public and private hospitals in Victoria from 2002-2003 to 2015-2016. Injury incidence rates per 100 000 Victorian population per financial year and age-stratified and sex-stratified injury incidence rates are presented. Poisson regression was used to examine trends in injury rates over the study period. ED presentation and HA rates were 31.1 and 6.6 per 100 000 person-years, increasing by 28.8% and 47.6% from 2002 to 2016, respectively. Female riders (47.3 ED and 10.1 HA per 100 000 person-years) and those aged between 10 and 14 years (87.8 ED and 15.7 HA per 100 000 person-years) had the highest incidence rates. Fractures (ED 29.4%; HA 56.5%) and head injuries (ED 15.4%; HA 18.9%) were the most common injuries. HA had a mean stay of 2.6±4.1 days, and the mean cost per HA was $A5096±8345. Horse-riding injuries have remained similar in their pattern (eg, types of injuries) since last reported in Victoria. HA and ED incidence rates have increased over the last 14 years. Refocusing on injury prevention countermeasures is recommended along with a clear plan for implementation and evaluation of their effectiveness in reducing injury.

    To define target populations for sports injury prevention programs. A computer-assisted telephone survey on sports injuries and sports participation during 2000-2005 using a 3-month recall period. Data obtained from a representative sample of Dutch citizens. Fifty-eight thousand four hundred five Dutch citizens aged older than 3 years. Age, gender, and type of sports were used to distinguish subgroups with a substantial contribution to sports injuries. The absolute number of sports injuries, the incidence of sports injuries per 10,000 hours, the severity, and costs of sports injuries. Sports participation was associated with 1.5 million injuries per year and 10 injuries per 10,000 hours; of these, 50% had to be treated medically. Two-thirds of all medically treated sports injuries were associated with 9 sports (representing 18 subpopulations, all younger than 55 years): outdoor soccer (males 4-54 years and females 4-17 years), indoor soccer (males 18-34 years), tennis (males/females 35-54 years), volleyball (females 18-54 years), field hockey (males 18-34 years and females 4-17 years), running/jogging (males/females 35-54 years), gymnastics (males/females 4-17 years), skiing/snowboarding (males 4-17 years and females 18-34 years), and equestrian sports (females 18-34 years). These groups showed more than average injury rates and covered two-thirds of all direct and indirect costs (euro 400 million). The survey identified the most important (sports-, age-, and gender-specific) target populations for injury prevention programs in the Netherlands. Sports participants aged older than 55 years were excluded from these target groups because of their limited contribution to the total sports injury problem.

    Adding external focus of attention (EF, focus on the movement effect) may optimize current anterior cruciate ligament (ACL) injury prevention programmes. The purpose of the current study was to investigate the effects of an EF, by a visual stimulus and an internal focus, by a verbal stimulus during unexpected sidestep cutting in female and male athletes and how these effects remained over time. Ninety experienced basketball athletes performed sidestep cutting manoeuvres in three sessions (S1, S2 and S3). In this randomized controlled trial, athletes were allocated to three groups: visual (VIS), verbal (VER) and control (CTRL). Kinematics and kinetics were collected at the time of peak knee frontal plane moment. Males in the VIS group showed a larger vertical ground reaction force (S1: 25.4 ± 3.1 N/kg, S2: 25.8 ± 2.9 N/kg, S3: 25.2 ± 3.2 N/kg) and knee flexion moments (S1: -3.8 ± 0.9 Nm/kg, S2: -4.0 ± 1.2 Nm/kg, S3: -3.9 ± 1.3 Nm/kg) compared to the males in the VER and CTRL groups and to the females in the VIS group (p knee valgus moment and the females in the VER group reduced knee varus moment over time (n.s.). Male subjects clearly benefit from visual feedback. Females may need different feedback modes to learn a correct movement pattern. Sex-specific learning preferences may have to be acknowledged in day by day practice. Adding video instruction or feedback to regular training regimens when teaching athletes safe movement patterns and providing individual feedback might target suboptimal long-term results and optimize ACL injury prevention programmes.

    Preventive medicine techniques have alleviated billions of dollars' worth of the economic burden in the medical care system through the implementation of vaccinations and screenings before the onset of disease symptoms. Knowledge of biomechanical tendencies has progressed rapidly over the past 20 years such that clinicians can identify, in healthy athletes, the underlying mechanisms that lead to catastrophic injuries such as anterior cruciate ligament (ACL) ruptures. As such, preventive medicine concepts can be applied to noncontact musculoskeletal injuries to reduce the economic burden of sports medicine treatments and enhance the long-term health of athletes. To illustrate the practical medical benefits that could be gained from preventive biomechanics applied to the ACL as well as the need and feasibility for the broad implementation of these principles. Literature review. The recent literature pertinent to the screening and prevention of musculoskeletal injuries was reviewed and compiled into a clinical commentary on the current state and applicability of preventive biomechanics. Investigators have identified neuromuscular training protocols that screen for and correct the underlying biomechanical deficits that lead to ACL injuries. The literature shows that when athletes comply with these prescribed training protocols, the incidence of injuries is significantly reduced within that population. Such preventive biomechanics practices employ basic training methods that would be familiar to athletic coaches and have the potential to save billions of dollars in cost in sports medicine. The widespread implementation of preventive biomechanics concepts could profoundly affect the field of sports medicine with a minimum of initial investment.

    To categorise discrepancies in findings of the menisci and anterior cruciate ligament (ACL) between arthroscopy and MRI. Materials and methods: The MRIs of 236 patients were retrospectively analysed by an experienced radiologist without knowledge of clinical and/for operative findings. Discrepancies in arthroscopic findings were reevaluated together with the arthroscopist to determine their cause of error. Results: The diagnostic accuracies for injuries of the medial and lateral meniscus and the ACL were 92.4%, 92.4%, and 94.1%. respectively. For the menisci, causes for discrepancies in findings (n=31) were: overinterpretation of central signal intensities with contact to the meniscal surface but without disturbance of the meniscal contour as a tear (n=12), insufficient arthroscopie evaluation of the knee joint (n=11), overlooked tears on MR imaging (n=6), misinterpretation of normal anatomic structures (n=1), ''magic angle'' phenomenon (n=1), and missed tears at MRI (n=1). Causes for discrepancies for the ACL (n=18) were: nearly complete versus complete rupture either at MRI or arthroscopy and vice versa (n=9), insufficient arthroscopic evaluation (n=6), insufficient MRI technique (n=2), and overlooked tear on MR imaging (n=1). Conclusions: Discrepant findings between MRI and arthroscopy may be also due to an insufficient arthroscopic evaluation in clinical routine. The close cooperation between surgeons and radiologists improves the understanding of the methods of each other. (orig.) [de

    Unintentional injury remains an important global public health issue, and efforts to address it are often hampered by a lack of visibility, leadership, funding, infrastructure, capacity and evidence of effective solutions. The growing support for a socioecological model and a systems approach to prevention-along with the acknowledgement that injury prevention can be a byproduct of salutogenic design and activities-has increased opportunities to integrate unintentional injury prevention into other health promotion and disease prevention agendas. It has also helped to integrate it into the broader human development agenda through the Sustainable Development Goals. This growing support provides new opportunities to use a human rights-based approach to address the issue. The human rights-based approach is based on the idea that all members of society have social, economic and cultural rights and that governments are responsible and accountable for upholding those rights. It incorporates a systems approach, addresses inequity and places an emphasis on the most vulnerable corners of humanity. It also leverages legal statutes and provides organisations with the opportunity to build existing international goals and benchmarks into their monitoring efforts. This paper describes the approach and highlights how it can leverage attention and investment to address current challenges for unintentional injury. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

    In badminton, knees opposite to the racket-hand side received anterior cruciate ligament (ACL) injuries during single-leg landing after overhead stroke. Most of them occurred in the backhand-side of the rear court. Comparing lower limb biomechanics during single-leg landing after overhead stroke between the forehand-side and backhand-side court may help explain the different injury rates depending on court position. The knee kinematics and kinetics during single-leg landing after overhead stroke following back-stepping were different between the forehand-side and backhand-side court. Controlled laboratory study. Hip, knee and ankle joint kinematic and knee kinetic data were collected for 17 right-handed female college badminton players using a 3-dimensional motion analysis system. Subjects performed single-left-legged landing after an overhead stroke following left and right back-stepping. The kinematic and kinetic data of the left lower extremities during landing were measured and compared between left and right back-steps. Hip flexion and abduction and knee valgus at the initial contact, hip and knee flexion and knee valgus at the maximum knee flexion and the maximum knee valgus moment were significantly larger for the left back-step than the right back-step (p<0.05). Significant differences in joint kinematics and kinetics of the lower extremity during single-leg landing after overhead stroke were observed between different back-step directions. Increased knee valgus angle and moment following back-stepping to the backhand-side might be related to the higher incidence of ACL injury during single-leg landing after overhead stroke.

    This article presents a critical review of the extent to which alpine ski bindings and their adjustment have been formally demonstrated to prevent injuries. It considers a range of evidence, from anecdotal evidence and informed opinion to biomechanical studies, testing of equipment, epidemiological studies and controlled field evaluations. A total of 15 published studies examining the effectiveness of bindings and their adjustment were identified. All of these included anecdotal or informed opinion, and all but one focused on equipment design. Seven studies involved the testing of bindings or binding prototypes, 2 studies presented biomechanical models of the forces involved in binding operation, 6 reported an epidemiological evaluation of ski bindings and 2 considered skiers' behaviours towards binding adjustment. Some of the reviewed articles relate to the study of the biomechanics of ski bindings and their release in response to various loads and loading patterns. Other studies examined the contribution of bindings and binding-release to lower extremity, equipment-related injuries, the effect of various methods of binding adjustment on injury risk and the determinants of skiers' behaviour relating to professional binding adjustment. Most of the evidence suggests that currently used bindings are insufficient for the multidirectional release required to reduce the risk of injury to the lower limb, especially at the knee. This evidence suggests that further technical developments and innovations are required. The standard of the manufacture of bindings and boots also needs to be considered. The optimal adjustment of bindings using a testing device has been shown to be associated with a reduced risk of lower extremity injury. Generally, however, the adjustment of bindings has been shown to be inadequate, especially for children's bindings. Recommendations for further research, development and implementation with respect to ski binding and their adjustment are given

    Neuromuscular Electrical Stimulation is a common intervention to address muscle weakness, however presents with many limitations such as fatigue, muscle damage, and patient discomfort that may influence its effectiveness. One novel form of electrical stimulation purported to improve neuromuscular re-education is Patterned Electrical Neuromuscular Stimulation (PENS), which is proposed to mimic muscle-firing patterns of healthy individuals. PENS provides patterned stimulating to the agonist muscle, antagonist muscle and then agonist muscle again in an effort to replicate firing patterns. The purpose of this study was to determine the effect of a single PENS treatment on knee extension torque and quadriceps activation in individuals with quadriceps inhibition. 18 subjects (10 males and 8 females: 24.2±3.4 years, 175.3±11.8cm, 81.8±12.4kg) with a history of knee injury/pain participated in this double-blinded randomized controlled laboratory trial. Participants demonstrated quadriceps inhibition with a central activation ratio of ≤90%. Maximal voluntary isometric contraction of the quadriceps and central activation ratio were measured before and after treatment. The treatment intervention was a 15-minute patterned electrical stimulation applied to the quadriceps and hamstring muscles with a strong motor contraction or a sham group, who received an identical set up as the PENS group, but received a 1mA subsensory stimulation. A 2×2 (group × time) ANCOVA was used to determine differences in maximal voluntary isometric contraction and central activation ratio between groups. The maximal voluntary isometric contraction was selected as a covariate due to baseline differences. There were no differences in change scores between pre- and post-intervention for maximal voluntary isometric contraction: (PENS: 0.09±0.32Nm/kg and Sham 0.15±0.18Nm/kg, p=0.713), or central activation ratio:(PENS: -1.22±6.06 and Sham: 1.48±3.7, p=0.270).

    Proprioception has been defined as the capacity to feel the position of a joint in space as sensed by the central nervous system. Prophylactic knee braces are supposed to help in knee injury prevention not just with a mechanical support of the joint but also improving proprioception. The main aim of this study was to determine the effects of a knee brace and a knee sleeve on knee proprioception. The secondary aim was to determine if different starting angles of the knee and different movement directions influence knee proprioception. We tested a group of twenty healthy male sport students without knee injuries. They were tested with the brace, with the sleeve and without support. The threshold of detection of passive knee movement with a starting knee angle of 30° and 60°, both in flexion and extension was determined. We did not find any statistically significant change in the threshold of detection of passive knee movement wearing the brace or the sleeve compared to the unsupported condition (p=0.462, α=0.05). We found a significantly lower proprioceptive sensitivity starting at the more flexed knee angle (p=0.005, α=0.05) and moving in extension than in the other test situations (p=0.001, α=0.05). Movement direction and starting position appear to influence the threshold of detection of passive knee movement. The results of this study also suggest that knee supports do not influence either positively or negatively knee proprioception of uninjured active subjects. Copyright © 2013 Elsevier B.V.

    Soccer is the most common sport activity worldwide. Over the last two decades the increase in soccer players has mainly been due to increased interest by females. In general, soccer is a relatively safe sport activity, especially if minor injuries resulting in short periods of absence from playing or training are neglected. However, due to the high number of soccer players severe injuries are also frequent. These are a problem not only for the injured player and the team but may also become problematic for the socio-economic system. In up to 80-90% structures of the lower extremities are injured. For sufficient radiological diagnosis knowledge of the biomechanics of the soccer game and some details about the history of the injury may be of help. To prevent soccer injuries or keep the degree of injury low, special programs had been developed. (orig.) [German] Fussball ist die weltweit am meisten verbreitete Sportart. Der Zuwachs an Fussballspieler(innen) in den letzten beiden Jahrzehnten wird jedoch hauptsaechlich auf das verstaerkte Interesse an weiblichen Spielern zurueckgefuehrt.

    Forensic toxicological data provides valuable insight into the potential contribution of alcohol and drugs to external-cause deaths. There is a paucity of material that guides injury researchers on the principles that need to be considered when examining the presence and contribution of alcohol and drugs to these deaths. This paper aims to describe and discuss strengths and limitations of postmortem forensic toxicology sample selection, variations in analytical capabilities and data interpretation for injury prevention research. Issues to be considered by injury researchers include: the circumstances surrounding death (including the medical and drug use history of the deceased person); time and relevant historical factors; postmortem changes (including redistribution and instability); laboratory practices; specimens used; drug concentration; and attribution of contribution to death. This paper describes the range of considerations for testing and interpreting postmortem forensic toxicology, particularly when determining impairment or toxicity as possible causal factors in injury deaths. By describing these considerations, this paper has application to decisions about study design and case inclusion in injury prevention research, and to the interpretation of research findings.

    This original prospective cohort study was conducted in an attempt to significantly reduce the incidence and the severity of injuries in an intervention cohort as compared to a two-season historical cohort, and to provide recommendations to the International Federation of Football (IFAF) pertaining to prevention measures to make the game safer. A total of 1,260 amateur male (mean age: 20.4 ± 3.9 years) and 244 female (mean age: 18.5 ± 1.7 years) players participated in the study. Four prevention measures were implemented: the no-pocket rule, self-fitting mouth guards, ankle braces (for those players with recurrent ankle sprains) and an injury treatment information brochure. All time-loss injuries sustained in game sessions were recorded by the off-the-field medical personnel and followed up by a more detailed phone injury surveillance questionnaire. There was a 54 % reduction in the total number of injuries and a significant reduction in the incidence rate and incidence proportion between the intervention cohorts as compared to the historical cohort (p football. Recommendations to the IFAF include strict enforcement of the no-pocket rule, the use of soft headgear, comfortable-fitting ankle braces and mouth guards and additionally, to change game rules concerning blocking.

  7. Injury prevention: a strategic priority for environmental health?

    Science.gov (United States)

    Stone, D H; Morris, G P

    2010-10-01

    Injury results from the acute transfer of energy (or the acute lack of a vital element) from the environment to human tissue. It is thus, ipso facto, an 'environmental health' issue par excellence. This paper argues that injury consequently deserves consideration as a major strategic priority by environmental health professionals. Two international agreements concerning children's health and the environment have major implications for safety. The Children's Environmental Health Action Plan for Europe (CEHAPE) and the European Environmental Health Strategy make reference to the need for improved evidence and greater co-operation between the environmental and health sectors. CEHAPE is particularly relevant to safety as it focuses on four regional priority goals, the second of which refers to the prevention and reduction of health consequences from injuries by promoting safe, secure and supportive human settlements for all children. The natural strategic 'home' for injury prevention may therefore lie within environmental health, a domain from which it has generally been excluded. In support of this assertion, Scotland's recent policy initiative on the environment and human health 'Good Places, Better Health' is cited, where injury in children up to 8 years of age is one of four child health priorities being tackled during its initial implementation. An important test of the initiative may be its capacity to inform policy, practice and research in the field of injury prevention and safety promotion. If successful, it will help to validate the environmental health approach to a field that remains relatively neglected by public agencies, policy makers, practitioners and researchers.

    Full Text Available CONTEXT AND OBJECTIVE Orthopedic surgery implies high costs for both public and private healthcare. The aim of this study was to better understand the differences between the public and private sectors regarding treatment of a damaged anterior cruciate ligament, which is a common knee injury. DESIGN AND SETTING Descriptive cross-sectional study conducted during the Brazilian Orthopedics Congress in Brasília. METHODS We applied questionnaires during the 2010 Brazilian Orthopedics Congress, with participation by 241 knee surgeons from 24 Brazilian states. This was followed by statistical analysis on the data that were obtained. RESULTS The orthopedic surgeons who were evaluated used different approaches and treatment options in different Brazilian states, comparing between the public and private systems. CONCLUSION Both in the public and in the private systems in Brazil, because of non-medical issues surrounding the treatment, the best medical decision is not always made. This may be harmful both to patients and to physicians.

    BACKGROUND: Meaningful change scores in the Knee injury and Osteoarthritis Outcome Score (KOOS) in patients undergoing anterior cruciate ligament (ACL) reconstruction have not yet been established. PURPOSE: To define the minimal important change (MIC) for the KOOS after ACL reconstruction. STUDY...... data for at least one of the KOOS subscales were obtained from 542 (45.3%) participants. Predictive modeling MIC values were 12.1 for the KOOS subscales of Sport and Recreational Function and 18.3 for Knee-Related Quality of Life. These values aid in interpreting within-group improvement over time...... and can be used as responder criteria when comparing groups. The corresponding and much lower values for the subscales of Pain (2.5), Symptoms (-1.2), and Activities of Daily Living (2.4) are the results from patients reporting, on average, only mild problems with these domains preoperatively. Although 4...

    Recent field data analysis has demonstrated that knee airbags (KABs) can reduce occupant femur and pelvis injuries but may be insufficient to decrease leg injuries in motor vehicle crashes. An enhanced understanding of the associated injury mechanisms requires accurate assessment of physiological-based occupant parameters, some of which are difficult or impossible to obtain from experiments. This study sought to explore how active muscle response can influence the injury risk of lower extremities during KAB deployment using computational biomechanical analysis. A full-factorial matrix, consisting of 48 finite element simulations of a 50th percentile occupant human model in a simplified vehicle interior, was designed. The matrix included 32 new cases in combination with 16 previously reported cases. The following influencing factors were taken into account: muscle activation, KAB use, KAB design, pre-impact seating position, and crash mode. Responses of 32 lower extremity muscles during emergency braking were replicated using one-dimensional elements of a Hill-type constitutive model, with the activation level determined from inverse dynamics and validated by existing volunteer tests. Dynamics of unfolding and inflating of the KABs were represented using the state-of-the-art corpuscular particle method. Abbreviated Injury Scale (AIS) 2+ injury risks of the knee-thigh-hip (KTH) complex and the tibia were assessed using axial force and resultant bending moments. With all simulation cases being taken together, a general linear model was used to assess factor significance (P systems. Future efforts are recommended on realistic vehicle and restraint environment and advanced modeling strategies toward a full understanding of KAB efficacy.

    Sport participation confers many varied benefits in children and adolescents, such as self-esteem, confidence, team play, fitness, agility and strength. Nevertheless, the age of initiation of intense training is decreasing and programmes which expose children to excessive amounts of exercise increase the risk of injury. We review sports injuries in young athletes and the long-term outcomes. Sports injuries can lead to disturbances in growth such as limb length discrepancy, caused by traumatised physeal growth induced by injury. Osgood-Schlatter lesion may also cause some sequelae such as painful ossicles in the distal patellar tendon. The apophysis can be fragmentised or separated, and this could be an adaptive change to the increased stress typical of overuse activities. These changes produce an osseous reaction even though they are not disabling. Participation in physical exercise at a young age should be encouraged, because of the health benefits, but decreasing the incidence and severity of sports injuries in young athletes is an important component of any athletic programme and may generate a long-term economic impact in health care costs. Active prevention measures are the main weapon to decrease the (re-)injury rate and to increase athletic performance. Copyright © 2011 S. Karger AG, Basel.

    Full Text Available This study aimed to support the potential protective role of anterior cruciate ligament (ACL reconstruction against the development of osteoarthritis (OA.In this retrospective cohort study, the long-term results of ACL reconstruction in Taiwan were evaluated based on data from the National Health Insurance Research Database (NHIRD. In total, 8,769 eligible cases were included from 11,921 ACL-injured patients. The cumulative incidence rates of OA and total knee replacement (TKR were analyzed using the Kaplan-Meier estimator. Cox proportional hazards models were applied to estimate the hazard ratios (HRs and 95% confidence intervals (CIs of OA.There was a lower cumulative incidence of OA among ACL-reconstructed patients (271, 33.1% than among non-reconstructed patients (1,874, 40.3%; p < 0.001. Patients who underwent ACL reconstruction had a lower cumulative incidence of TKR during the follow-up period (0.6% than the non-reconstructed patients (4.6%, p < 0.001. After adjusting for covariates, ACL-injured patients who underwent reconstruction within one month after ACL injury showed a significantly lower risk of OA than those who never underwent reconstruction (adjusted HR = 0.83, 95% CI = 0.69-0.99.These results indicate that ACL reconstruction might not provide complete protection from OA development after traumatic knee injury but does yield a lower cumulative incidence of OA development and TKR. Moreover, based on the present study, ACL-injured patients should undergo reconstruction as early as possible (within one month to lower the risk of OA.

    Menisci help maintain the structural integrity of the knee. However, the poor healing potential of the meniscus following a knee injury can not only end a career in sports but lead to osteoarthritis later in life. Complete understanding of meniscal structure is essential for evaluating its risk for injury and subsequent successful repair. This study used novel approaches to elucidate meniscal architecture. The radial and circumferential collagen fibrils in the meniscus were investigated using novel tissue-preparative techniques for light and electron microscopic studies. The results demonstrate a unique architecture based on differences in the packaging of the fundamental collagen fibrils. For radial arrays, the collagen fibrils are arranged in parallel into ∼10 μm bundles, which associate laterally to form flat sheets of varying dimensions that bifurcate and come together to form a honeycomb network within the body of the meniscus. In contrast, the circumferential arrays display a complex network of collagen fibrils arranged into ∼5 μm bundles. Interestingly, both types of architectural organization of collagen fibrils in meniscus are conserved across mammalian species and are age and sex independent. These findings imply that disruptions in meniscal architecture following an injury contribute to poor prognosis for functional repair. © 2010 John Wiley & Sons A/S.

    Treadmills are a burn risk for children. A child's hand can get trapped in the conveyor belt, causing friction burns to the underlying tissue. The purpose of this retrospective study was to review the characteristics and treatment of treadmill-related burns in children from 1998 to 2002. Ten patients, at a mean age of 3.4 years, sustained injuries associated with treadmill use. Trapping of the hand between the conveyor belt and the base was the most frequent injury mechanism. Burn location was predominantly on fingers and palms. Four patients required operative intervention. All patients required specialized wound care as well as scar management and occupational therapy. Treadmills pose a danger to children. Current safety devices are ineffective for preventing serious hand injuries in children. New design modifications and public awareness are needed to improve child safety.

    Rugby union football has long been one of the most popular sports in the world. Its popularity and number of participants continue to increase in the United States. Until 1995, rugby union primarily was an amateur sport. Worldwide there are now flourishing professional leagues in many countries, and after a long absence, rugby union will be returning to the Olympic games in 2016. In the United States, rugby participation continues to increase, particularly at the collegiate and high school levels. With the increase in rugby professional athletes and the reported increase in aggressive play, there have been changes to the injury patterns in the sport. There is still significant need for further epidemiologic data as there is evidence that injury prevention programs and rule changes have been successful in decreasing the number of catastrophic injuries in rugby union.

    The recent development of a soft tissue artifact (STA) suppression method allows us to re-evaluate the tibiofemoral kinematics currently linked to non-contact knee injuries. The purpose of this study was therefore to evaluate knee joint kinematics and kinetics in six degrees of freedom (DoF) during the loading phases of a jump lunge and side cut using this in silico method. Thirty-five healthy adults completed these movements and their surface marker trajectories were then scaled and processed with OpenSim's inverse kinematics (IK) and inverse dynamics tools. Knee flexion angle-dependent kinematic constraints defined based on previous bone pin (BP) marker trajectories were then applied to the OpenSim model during IK and these constrained results were then processed with the standard inverse dynamics tool. Significant differences for all hip, knee, and ankle DoF were observed after STA suppression for both the jump lunge and side cut. Using clinically relevant effect size estimates, we conclude that STA contamination had led to misclassifications in hip transverse plane angles, knee frontal and transverse plane angles, medial/lateral and distractive/compressive knee translations, and knee frontal plane moments between the NoBP and the BP IK solutions. Our results have substantial clinical implications since past research has used joint kinematics and kinetics contaminated by STA to identify risk factors for musculoskeletal injuries.

    In the ECE 127 Regulation on pedestrian leg protection, as well as in the Euro NCAP test protocol, a legform impactor hits the vehicle at the speed of 40 kph. In these tests, the knee is fully extended and the leg is not coupled to the upper body. However, the typical configuration of a pedestrian impact differs since the knee is flexed during most of the gait cycle and the hip joint applies an unknown force to the femur. This study aimed at investigating the influence of the inertia of the upper body (modelled using an upper body mass fixed at the proximal end of the femur) and the initial knee flexion angle on the lower limb injury outcome. In total, 18 tests were conducted on 18 legs from 9 Post Mortem Human Subjects (PMHS). The principle of these tests was to impact the leg at 40 kph using a sled equipped with 3 crushing steel tubes, the stiffness of which were representative of the front face of a European sedan (bonnet leading edge, bumper and spoiler). The mass of the equipped sled was 74.5 kg. The test matrix was designed to perform 4 tests in 4 configurations combining two upper body masses (either 0 or 3 kg) and two knee angles (0 or 20 degrees) at 40 kph (11 m/s) plus 2 tests at 9 m/s. Autopsies were performed on the lower limbs and an injury assessment was established. The findings of this study were first that the increase of the upper body mass resulted in more severe injuries, second that an initial flexion of the knee, corresponding to its natural position during the gait cycle, decreased the severity of the injuries, and third that based on the injury outcome, a test conducted with no upper body mass and the knee fully extended was as severe as a test conducted with a 3 kg upper body mass and an initial knee flexion of 20°.

The goalkeepers are more exposed to shoulder disorders than other field players. Injury prevention exercises for upper limbs were cited in few studies involving throwing athletes, but we know that goalkeepers need a specific program. The purpose of this study is to describe the development of an adapted Fédération Internationale de Football Association (FIFA 11+ program, namely the FIFA 11+ shoulder, which targets the prevention of shoulder injuries in soccer goalkeepers. The FIFA 11+ shoulder program is structured into three parts: general warming-up exercises, exercises to improve strength and balance of the shoulder, elbow, wrist, and finger muscles, and advanced exercises for core stability and muscle control. The exercises were selected based on recommendations from studies demonstrating high electromyographic activity. Keywords: goalkeeper, shoulder, injury prevention, prevention program

  20. Principles of brain plasticity in improving sensorimotor function of the knee and leg in patients with anterior cruciate ligament injury: a double-blind randomized exploratory trial

    Full Text Available Abstract Background Severe traumatic knee injury, including injury to the anterior cruciate ligament (ACL, leads to impaired sensorimotor function. Although improvements are achieved by training, impairment often persists. Because good sensorimotor function is associated with better patient-reported function and a potential lower risk of future joint problems, more effective treatment is warranted. Temporary cutaneous anesthesia of adjacent body parts was successfully used on the hand and foot to improve sensorimotor function. The aim of this study was to test whether this principle of brain plasticity could be used on the knee. The hypothesis was that temporary anesthesia of the skin area above and below the knee would improve sensorimotor function of the ipsilateral knee and leg in subjects with ACL injury. Methods In this double-blind exploratory study, 39 subjects with ACL injury (mean age 24 years, SD 5.2, 49% women, mean 52 weeks after injury or reconstruction and self-reported functional limitations and lack of trust in the knee were randomized to temporary local cutaneous application of anesthetic (EMLA® (n = 20 or placebo cream (n = 19. Fifty grams of EMLA®, or placebo, was applied on the leg 10 cm above and 10 cm below the center of patella, leaving the area around the knee without cream. Measures of sensory function (perception of touch, vibration sense, knee kinesthesia and motor function (knee muscle strength, hop test were assessed before and after 90 minutes of treatment with EMLA® or placebo. The paired t-test was used for comparisons within groups and analysis of variance between groups, except for ordinal data where the Wilcoxon signed rank test, or Mann–Whitney test, was used. The number of subjects needed was determined by an a priori sample size calculation. Results No statistically significant or clinically relevant differences were seen over time (before vs. after in the measures of sensory or motor

    Little is known regarding movement strategies in the long term following injury of the anterior cruciate ligament (ACL), and even less about comparisons of reconstructed and deficient knees in relation to healthy controls. The present purpose was to compare trunk, hip, and knee kinematics during a one-leg vertical hop (VH) ~20 years post-ACL injury between persons treated with surgery and physiotherapy (ACL R ), solely physiotherapy (ACL PT ), and controls (CTRL). Between-leg kinematic differences within groups were also investigated. Sixty-six persons who suffered unilateral ACL injury on average 23 ± 2 years ago (32 ACL R , 34 ACL PT ) and 33 controls performed the VH. Peak trunk, hip, and knee angles during Take-off and Landing phases recorded with a 3D motion capture system were analysed with multivariate statistics. Significant group effects during both Take-off and Landing were found, with ACL PT differing from CTRL in Take-off with a combination of less knee flexion and knee internal rotation, and from both ACL R and CTRL in Landing with less hip and knee flexion, knee internal rotation, and greater hip adduction. ACL R also presented different kinematics to ACL PT and CTRL in Take-off with a combination of greater trunk flexion, hip flexion, hip internal rotation, and less knee abduction, and in Landing with greater trunk flexion and hip internal rotation. Further, different kinematics and hop height were found between legs within groups in both Take-off and Landing for both ACL groups, but not for CTRL. Different kinematics for the injured leg for both ACL groups compared to CTRL and between treatment groups, as well as between legs within treatment groups, indicate long-term consequences of injury. Compensatory mechanisms for knee protection seem to prevail over time irrespective of initial treatment, possibly increasing the risk of re-injury and triggering the development of osteoarthritis.

Specific biomechanical and neuromuscular variables have been used to estimate the risk of incurring a non-contact injury in athletes.The aim of this study was to systematically review the evidences for the effectiveness of injury prevention protocols to modify biomechanical and neuromuscular anterior cruciate and/or hamstring injuries associated risk factors in uninjured team sport athletes.PubMed, Science Direct, Web of Science, Cochrane Libraries, U.S. National Institutes of Health clinicaltrials.gov, Sport Discuss and Google Scholar databases were searched for relevant journal articles published until March 2015. A manual review of relevant articles, authors, and journals, including bibliographies was performed from identified articles.Nineteen studies were included in this review. Four assessment categories: i landing, ii side cutting, iii stop-jump, and iv muscle strength outcomes, were used to analyze the effectiveness of the preventive protocols. Eight studies using multifaceted interventions supported by video and/or technical feedback showed improvement in landing and/or stop-jump biomechanics, while no effects were observed on side-cutting maneuver. Additionally, multifaceted programs including hamstring eccentric exercises increased hamstring strength, hamstring to quadriceps functional ratio and/or promoted a shift of optimal knee flexion peak torque toward a more open angle position.Multifaceted programs, supported by proper video and/or technical feedback, including eccentric hamstring exercises would positively modify the biomechanical and or neuromuscular anterior cruciate and/or hamstring injury risk factors.

    One of the leading causes of scald burn injury in children is from hot soup, particularly prepackaged instant soups. The purpose of this study was to determine the demographic, socioeconomic, and situational factors that contribute to the incidence of scald burns in children. A 20-item questionnaire was given to the caregiver of children who were treated for scald burn injury at a pediatric burn center from July 2006 to March 2007. Questions included demographics (child age, gender, siblings, ethnicity), socioeconomic status (income, education), factors contributing to the injury (type of soup, child supervision, type of container), and location of injury. The mean age of the 78 children sustaining burn injury and completing the survey was 4.8 +/- 0.6 years. The majority of patients were girls (51%), and the most frequently involved ethnic group was Hispanic (44%). Households had a mean of 3.0 +/- 0.3 children in residence, and an income of less than $29,000/year (59%). The highest educational level achieved was high school for 73% of the parents. Prepackaged soup (65%) with a narrow base heated directly in the original container (46%) using the microwave (51%) was implicated in the majority of burns. Soup scald burns, especially from prepackaged instant soups, appear to predominate in lower income families with multiple children. The majority of injuries occur when the caregiver heats the soup in the original container using the microwave. Prevention of these types of injuries will require a two-pronged approach: educating families with multiple children and changing the soup packaging.

    Full Text Available Purpose: As trauma is a public health problem, different programs have been designed to prevent injuries. The aim of this study was to evaluate the effectiveness of an educational model that measures the adolescents' attitudes towards the rules of road safety, alcohol and road accidents in Colombia. Methods: A pedagogical model evaluating the effect of road safety education and adolescents' attitudes towards and experiences of alcohol and road accidents in Colombia was created. After the education concluded, this educational process is analyzed by its impact on adolescents' behavior. The educational program included 160 adolescents with the mean age being 17.5 years. Results: The test results indicated that before the educational program 80% of adolescents did not use a safety element when driving, while after the educational program the percentage of no helmet use among adolescents decreased from 72.5% to 24.3% (p = 0.0001 and driving a vehicle under the state of drunkenness from 49.3% to 8.1% (p = 0.0001. Conclusion: An educational model aimed at preventing injuries caused by traffic accidents is shown to be effective in generating changes in adolescents' customs of and attitudes towards alcohol and road safety standards in Colombia.

    Integrating different theories of motivation to facilitate or predict behaviour change has received an increasing amount of attention within the health, sport and exercise science literature. A recent review article in Sports Medicine, by Keats, Emery and Finch presented an integrated model using two prominent theories in social psychology, self-determination theory (SDT) and the theory of planned behaviour (TPB), aimed at explaining and enhancing athletes' adherence to sport injury prevention. While echoing their optimistic views about the utility of these two theories to explain adherence in this area and the virtues of theoretical integration, we would like to seize this opportunity to clarify several conceptual principles arising from the authors' integration of the theories. Clarifying the theoretical assumptions and explaining precisely how theoretical integration works is crucial not only for improving the comprehensiveness of the integrated framework for predicting injury prevention behaviour, but also to aid the design of effective intervention strategies targeting behavioural adherence. In this article, we use the integration of SDT and TPB as an example to demonstrate how theoretical integration can advance the understanding of injury prevention behaviour in sport.

    Objective To apply human performance concepts in an attempt to understand the causes of and prevent laparoscopic bile duct injury. Summary Background Data Powerful conceptual advances have been made in understanding the nature and limits of human performance. Applying these findings in high-risk activities, such as commercial aviation, has allowed the work environment to be restructured to substantially reduce human error. Methods The authors analyzed 252 laparoscopic bile duct injuries according to the principles of the cognitive science of visual perception, judgment, and human error. The injury distribution was class I, 7%; class II, 22%; class III, 61%; and class IV, 10%. The data included operative radiographs, clinical records, and 22 videotapes of original operations. Results The primary cause of error in 97% of cases was a visual perceptual illusion. Faults in technical skill were present in only 3% of injuries. Knowledge and judgment errors were contributory but not primary. Sixty-four injuries (25%) were recognized at the index operation; the surgeon identified the problem early enough to limit the injury in only 15 (6%). In class III injuries the common duct, erroneously believed to be the cystic duct, was deliberately cut. This stemmed from an illusion of object form due to a specific uncommon configuration of the structures and the heuristic nature (unconscious assumptions) of human visual perception. The videotapes showed the persuasiveness of the illusion, and many operative reports described the operation as routine. Class II injuries resulted from a dissection too close to the common hepatic duct. Fundamentally an illusion, it was contributed to in some instances by working too deep in the triangle of Calot. Conclusions These data show that errors leading to laparoscopic bile duct injuries stem principally from misperception, not errors of skill, knowledge, or judgment. The misperception was so compelling that in most cases the surgeon did not

    velocity, sequential movement patterns, higher elbow-flexion to knee-extension strength ratios, higher seat-to-handle velocity during the initial drive, or higher shoulder angle excursion may result in RSF. Gearing may indirectly affect rib loading. Increased risk may be due to low calcium, low vitamin D, eating disorders, low testosterone or use of depot medroxyprogesterone injections. Injury management involves 1-2 weeks cessation of rowing with analgesic modalities followed by a slow return to rowing with low-impact intensity and modified pain-free training. Some evidence shows injury prevention strategies should focus on strengthening the serratus anterior, strengthening leg extensors, stretching the lumbar spine, increasing hip joint flexibility, reducing excessive protraction, training with ergometers on slides or floating-head ergometers, and calcium and vitamin D supplementation. Future research should focus on the epidemiology of RSF over 4-year Olympic cycles in elite rowers, the aetiology of the condition, and the effectiveness of RSF prevention strategies for injury incidence and performance in rowing.

    Activity-related patient-reported outcome measures are an important component of assessment after knee ligament injury in young and physically active patients; however, normative data for most activity scales are limited. To present reference values by sex for the Marx Activity Rating Scale (MARS) within a young and physically active population while accounting for knee ligament injury history and sex. Cross-sectional study. Level 2. All incoming freshman entering a US Service Academy in June of 2011 were recruited to participate in this study. MARS was administered to 1169 incoming freshmen (203 women) who consented to participate within the first week of matriculation. All subjects were deemed healthy and medically fit for military service on admission. Subjects also completed a baseline questionnaire that asked for basic demographic information and injury history. We calculated means with standard deviations, medians with interquartile ranges, and percentiles for ordinal and continuous variables, and frequencies and proportions for dichotomous variables. We also compared median scores by sex and history of knee ligament injury using the Kruskal-Wallis test. MARS was the primary outcome of interest. The median MARS score was significantly higher for men when compared with women (χ(2) = 13.22, df = 1, P MARS scores between men and women (χ(2) = 0.47, df = 1, P = 0.493) who reported a history of injury. Overall, median MARS scores were significantly higher among those who reported a history of knee ligament injury when compared with those who did not (χ(2) = 9.06, df = 1, P = 0.003). Assessing activity as a patient-reported outcome after knee ligament injury is important, and reference values for these instruments need to account for the influence of prior injury and sex. © 2015 The Author(s).

    There are a variety of biologics, vaccines, antibiotics, and hormones used in animal agriculture. Depending upon the procedure or pharmaceutical used, accidental injections or product exposures can result in mild to severe injuries. Needlestick injury (NSI) prevention, research, and education for veterinarians and agriculture workers is limited. The objective of this study was to collect and review published case reports and case series/surveys on human needlestick exposure to veterinary biologics and to summarize needlestick prevention strategies for agricultural workers/veterinarians. A search was conducted of PubMed and Centre for Agriculture Bioscience International (CABI) databases. References were reviewed to identify additional articles. NSI among agricultural workers were primarily included in this review. Thirty articles were applicable to exposures in agricultural settings. Relevant literature consisted of case reports, survey/case series articles, prevention documents, and background articles. Fifty-nine case patients were identified. Most of these cases were associated with exposures to specific vaccines or veterinary products. Injury location was identified from 36 individuals: 24 (67%) NSI to the hands, 10 (28%) injuries to the legs, and 2 to other body locations. Of the 59 cases, 20 (34%) involved oil-adjuvant vaccines. Evidence of hospitalization was recorded for 30 case patients. The length of hospitalization was available from 11 case patients. Median length of hospitalization was 3 days (range: 1-4). Surgical intervention was reported in 25 case patients. Outcome information was available on 30 case patients. Fifteen made a complete recovery within 2 weeks of treatment, 14 had residual sequelae attributed to the injury, and there was 1 reported death. Of the 13 survey/case series articles: 2 focused on oil-adjuvant products, 1 on Brucellosis RB-51 vaccine, 3 on tilmicosin, 1 on Salmonella enteritidis vaccine, 1 on high-pressure injection, and 5

    Biofeedback training enables an athlete to alter biomechanical and physiological function by receiving biomechanical and physiological data concurrent with or immediately after a task. To compare the effects of 2 different modes of real-time biofeedback focused on reducing risk factors related to anterior cruciate ligament injury. Randomized crossover study design. Biomechanics laboratory and sports medicine center. Female high school soccer players (age 14.8 ± 1.0 y, height 162.6 ± 6.8 cm, mass 55.9 ± 7.0 kg; n = 4). A battery of kinetic- or kinematic-based real-time biofeedback during repetitive double-leg squats. Baseline and posttraining drop vertical jumps were collected to determine if either feedback method improved high injury risk landing mechanics. Maximum knee abduction moment and angle during the landing was significantly decreased after kinetic-focused biofeedback (P = .04). The reduced knee abduction moment during the drop vertical jumps after kinematic-focused biofeedback was not different (P = .2). Maximum knee abduction angle was significantly decreased after kinetic biofeedback (P < .01) but only showed a trend toward reduction after kinematic biofeedback (P = .08). The innovative biofeedback employed in the current study reduced knee abduction load and posture from baseline to posttraining during a drop vertical jump.

    Abstract The Injury and Illness Prevention Program (IIPP) requirement has been the most frequently cited standard in California workplace health and safety inspections almost every year since it became effective in July 1991. Every workplace safety inspection must assess compliance with the IIPP. This article presents the results of an evaluation of the IIPP's effects on worker injuries in California and should inform policy both in California and in the federal Occupational Safety and Health Administration (OSHA) program, which has made the adoption of a similar national requirement a top priority. Using data from the Workers' Compensation Information System, OSHA Data Initiative statistics, and Workers' Compensation Insurance Rating Bureau of California reports on medical and indemnity claims from single-establishment firms, the evaluation team analyzed the impact of citations for violations of the IIPP on safety performance by (1) using the number of citations as a measure of effectiveness and (2) assessing the number of establishments that were cited for noncompliance and then came into compliance. They found that enforcement of the IIPP appears to prevent injuries only when inspectors cite firms for violations of specific subsections of that standard. Eighty percent of the citations of the IIPP by the California Division of Occupational Safety and Health program are for only a different section, the one that requires employers to have a written IIPP. The specific subsections refer to the provisions that mandate surveying and fixing hazards, investigating the causes of injuries, and training employees to work safely. Because about 25 percent of all inspections cite the IIPP, citations of the specific subsections occur in about 5 percent of all inspections. In those inspections, the total recordable injury rate falls by more than 20 percent in the two years following the inspection. PMID:28083238

    Julie Wagner

    Full Text Available Mechanical ventilation is a life-saving clinical treatment but it can induce or aggravate lung injury. New therapeutic strategies, aimed at reducing the negative effects of mechanical ventilation such as excessive production of reactive oxygen species, release of pro-inflammatory cytokines, and transmigration as well as activation of neutrophil cells, are needed to improve the clinical outcome of ventilated patients. Though the inhaled anesthetic sevoflurane is known to exert organ-protective effects, little is known about the potential of sevoflurane therapy in ventilator-induced lung injury. This study focused on the effects of delayed sevoflurane application in mechanically ventilated C57BL/6N mice. Lung function, lung injury, oxidative stress, and inflammatory parameters were analyzed and compared between non-ventilated and ventilated groups with or without sevoflurane anesthesia. Mechanical ventilation led to a substantial induction of lung injury, reactive oxygen species production, pro-inflammatory cytokine release, and neutrophil influx. In contrast, sevoflurane posttreatment time dependently reduced histological signs of lung injury. Most interestingly, increased production of reactive oxygen species was clearly inhibited in all sevoflurane posttreatment groups. Likewise, the release of the pro-inflammatory cytokines interleukin-1β and MIP-1β and neutrophil transmigration were completely prevented by sevoflurane independent of the onset of sevoflurane administration. In conclusion, sevoflurane posttreatment time dependently limits lung injury, and oxidative and pro-inflammatory responses are clearly prevented by sevoflurane irrespective of the onset of posttreatment. These findings underline the therapeutic potential of sevoflurane treatment in ventilator-induced lung injury.

    Full Text Available Background: Needlestick and sharp injuries are a serious hazard in any health care setting for health care workers and students during clinical practice. Thus, the efforts to prevent the needlestick and sharps injuries are needed and considered a part of the routine practice. Objective: This study aimed to investigate the frequency of nursing students in doing the correct practice in prevention needlestick and sharps injuries. Methods: This cross- sectional study was conducted between 2013 and 2014 in nursing students of Tien Giang Medical College who participated in clinical practice. There were 360 students participated in the study using simple random sampling. Data were collected using the practical assessment checklist and demographic characteristics questionnaire. Data were processed using STATA 12.0, and analyzed using Chi-square and Fisher test. Results: The students who did general practice correctly accounted for 52.50%, and those who did practice incorrectly was 47.5%. The students who used gauze or wool wrap in inhaler were 59.7%, wearing gloves in practice (39.2%, do not disassemble needles from syringes after injection 50%, and removing needles into barrel after injection (65.6%. There was statistically significant relationship between time of participation in clinical practice and correct practice with p-value 0.04 (<0.05 Conclusion: The correct practice of nursing students related to the prevention of needlestick and sharps injuries remains low. There was a significant relationship between time of participation in clinical practice and correct nursing practice. It is suggested that students must be taught about the risk of infection at the beginning of clinical practice, and constantly reminded throughout the learning process, especially for injection safety awareness, knowledge and techniques about the risk of transmission of HBV, HCV and HIV by sharp objects in the healthcare facility.

    We examined the effectiveness of preventive interventions against occupational injuries (preferential action plans [PAPs]) developed by Spanish regional governments starting in 2000. We included 3,252,028 occupational injuries with sick leave due to mechanical causes occurring between 1994 and 2004 in manufacturing and private service companies. Time trends for occupational injury rates were estimated before and after implementation of PAPs in each region, with a control group defined for those regions in which no PAPs were implemented (e.g., Galicia, Madrid, and Cataluña). We determined annual change percentages and their 95% confidence intervals (CIs) through a negative binomial regression model. Regions were grouped into three categories according to formal quality of their PAPs. The regions with the best PAPs (Andalucia, Aragon, Valencia, and Murcia) showed annually increasing occupational injury rates (2.3%, 95% CI -2.5, 7.4) before implementation of PAPs. After PAPs were implemented, occupational injury rates decreased significantly to -7.4% (95% CI -10.2, -4.5). Similar results were also found for regions with PAPs of lower quality and even for regions that didn't implement a PAP (control group). These results did not vary substantially in stratified analysis by gender, age, type of contract, or length of sick leave. PAPs are not related to a general decline in occupational injury rates in Spain starting in 2000. Reinforcement of Spanish health and safety regulations and labor inspection activities since 2000, resulting from a social agreement between central government and social agents, remains an alternative hypothesis requiring additional research.

    We compared clinical and radiographic results after total knee arthroplasty (TKA) using Attune and Press Fit Condylar Sigma, and investigated whether use of the current prosthesis increased injury risk to the tibial cortex in Asian patients. We also assessed whether a preoperative posterior tibial slope angle (PSA) is associated with the injury when using the current prosthesis. The 300 TKAs with Attune (group A) were compared to the 300 TKAs with Press Fit Condylar Sigma (group B). Demographics were not different, except follow-up periods (24.8 vs 33.3 months, P Universities Index and range of motion were compared. A minimum distance between tibial component stem and posterior tibial cortex (mDSC) was compared. The correlation between preoperative PSA and mDSC was analyzed in group A. The postoperative Western Ontario and McMaster Universities Index and range of motion of group A were better than those of group B (17.7 vs 18.8, P = .004; 131.4° vs 129.0°, P = .008). The mDSC was shorter in group A (6.3 vs 7.0 mm, P < .001), which made up a higher proportion of the high-risk group for posterior tibial cortical injury with an mDSC of <4 mm (20.0% vs 10.7%, P = .002). A negative correlation was found between the preoperative PSA and mDSC in group A (r = -0.205, P < .001). The TKA using the current prosthesis provided more satisfactory results than the TKA using the previous prosthesis. However, the injury risk to the posterior tibial cortex increased in the knees with a large PSA when using the current prosthesis for Asian patients. Copyright © 2017 Elsevier Inc.

    The aim of this article is to report on three patients with injuries of the peroneal nerve along the posterolateral aspect of the knee. Injuries in this area are less common than the injuries occurring at the level of the fibular head. In this article we report on three patients with posterolateral knee trauma who had peroneal nerve dysfunction. To better understand the precise location of the nerve on MR images, we performed MR imaging in five volunteers, and studied the position of the nerve on anatomic dissection (n=1) and anatomic slices (n=1). The common peroneal nerve is easily depicted on MR images and has a typical location along the posterior margin of the biceps tendon. Non-visualisation of the peroneal nerve at the posterolateral aspect of the knee, as seen on MR images, is consistent with nerve injury. Scar tissue at the posterolateral aspect of the knee indicates injury of this specific area, and involvement of the peroneal nerve is likely. (orig.)

    It is estimated that by 2020 road traffic crashes will have moved from ninth to third in the world disease burden ranking, as measured in disability adjusted life years, and second in developing countries. The identification of effective strategies for the prevention of traffic related injuries is of global health importance. Area-wide traffic calming schemes that discourage through traffic on residential roads is one such strategy. To evaluate the effectiveness of area-wide traffic calming in preventing traffic related crashes, injuries, and deaths. We searched the following electronic databases: Cochrane Injuries Group's Specialised Register, Cochrane Controlled Trials Register, MEDLINE, EMBASE and TRANSPORT (NTIS, TRIS, TRANSDOC). We searched the web sites of road safety organisations, handsearched conference proceedings, checked reference lists of relevant papers and contacted experts in the area. The search was not restricted by language or publication status. Randomised controlled trials, and controlled before-after studies of area-wide traffic calming schemes. Two reviewers independently extracted data on type of study, characteristics of intervention and control areas, and length of data collection periods. Before and after data were collected on the total number of road traffic crashes, all road user deaths and injuries, pedestrian-motor vehicle collisions and road user deaths. The statistical package STATA was used to calculate rate ratios for each study, which were then pooled to give an overall estimate using a random effects model. We found no randomised controlled trials, but 16 controlled before-after trials met our inclusion criteria. Seven studies were done in Germany, six in the UK, two in Australia and one in the Netherlands. There were no studies in low or middle income countries. Eight trials reported the number of road traffic crashes resulting in deaths. The pooled rate ratio was 0.63 (0.14, 2.59 95% CI). Sixteen studies reported the number

    To update the current injury prevention strategy evidence base for making recommendations to prevent physical training-related musculoskeletal injury. We conducted a systematic review to update the evidence base on injury prevention strategies for military personnel. Literature was systematically searched and extracted from five databases, and reported according to PRISMA guidelines. Sixty one articles meeting the inclusion criteria and published during the period 2008-2015 were selected for systematic review. The retrieved articles were broadly categorised into six injury prevention strategies; (1) conditioning, (2) footwear modifications, (3) bracing, (4) physical activity volume, (5) physical fitness, and (6) leadership/supervision/awareness. The majority of retrieved articles (n=37 (of 61) evaluated or systematically reviewed a conditioning intervention of some nature. However, the most well-supported strategies were related to reducing physical activity volume and improving leadership/supervision/awareness of injuries and injury prevention efforts. Several injury prevention strategies effectively reduce musculoskeletal injury rates in both sexes, and many show promise for utility with military personnel. However, further evaluation, ideally with prospective randomised trials, is required to establish the most effective injury prevention strategies, and to understand any sex-specific differences in the response to these strategies.

    2018-05-01

    Full Text Available Impaired walking increases injury risk during locomotion, including falls-related acute injuries and overuse damage to lower limb joints. Gait impairments seriously restrict voluntary, habitual engagement in injury prevention activities, such as recreational walking and exercise. There is, therefore, an urgent need for technology-based interventions for gait disorders that are cost effective, willingly taken-up, and provide immediate positive effects on walking. Gait control using shoe-insoles has potential as an effective population-based intervention, and new sensor technologies will enhance the effectiveness of these devices. Shoe-insole modifications include: (i ankle joint support for falls prevention; (ii shock absorption by utilising lower-resilience materials at the heel; (iii improving reaction speed by stimulating cutaneous receptors; and (iv preserving dynamic balance via foot centre of pressure control. Using sensor technology, such as in-shoe pressure measurement and motion capture systems, gait can be precisely monitored, allowing us to visualise how shoe-insoles change walking patterns. In addition, in-shoe systems, such as pressure monitoring and inertial sensors, can be incorporated into the insole to monitor gait in real-time. Inertial sensors coupled with in-shoe foot pressure sensors and global positioning systems (GPS could be used to monitor spatiotemporal parameters in real-time. Real-time, online data management will enable ‘big-data’ applications to everyday gait control characteristics.

    A retrospective study. Precise classification of the neurological state of patients with acute cervical spinal cord injury (CSCI) can be challenging. This study proposed a useful and simple clinical method to help classify patients with incomplete CSCI. Spinal Injuries Centre, Japan. The sensitivity and specificity of the 'knee-up test' were evaluated in patients with acute CSCI classified as American Spinal Injury Association Impairment Scale (AIS) C or D. The result is positive if the patient can lift the knee in one or both legs to an upright position, whereas the result is negative if the patient is unable to lift the knee in either leg to an upright position. The AIS of these patients was classified according to a strict computerised algorithm designed by Walden et al., and the knee-up test was tested by non-expert examiners. Among the 200 patients, 95 and 105 were classified as AIS C and AIS D, respectively. Overall, 126 and 74 patients demonstrated positive and negative results, respectively, when evaluated using the knee-up test. A total of 104 patients with positive results and 73 patients with negative results were classified as AIS D and AIS C, respectively. The sensitivity, specificity, positive predictive and negative predictive values of this test for all patients were 99.1, 76.8, 82.5 and 98.7, respectively. The knee-up test may allow easy and highly accurate estimation, without the need for special skills, of AIS classification for patients with incomplete CSCI.

    As the leading cause of death and among the top causes of hospitalisation in Canadians aged 1-44 years, injury is a major public health concern. Little is known about whether knowledge, training and understanding of the underlying causes and mechanisms of injury would help with one's own prevention efforts. Based on the Theory of Planned Behaviour, we hypothesised that injury prevention professionals would experience fewer injuries than the general population. An online cross-sectional survey was distributed to Canadian injury prevention practitioners, researchers and policy makers to collect information on medically attended injuries. Relative risk of injury in the past 12 months was calculated by comparing the survey data with injury incidence reported by a comparable subgroup of adults from the (Canadian Community Health Survey (CCHS)) from 2009 to 2010. We had 408 injury prevention professionals complete the survey: 344 (84.5%) women and 63 (15.5%) men. In the previous 12 months, 86 individuals reported experiencing at least one medically attended injury (21,235 people per 100,000 people); with sports being the most common mechanism (41, 33.6%). Fully 84.8% individuals from our sample believed that working in the field had made them more careful. After accounting for age distribution, education level and employment status, injury prevention professionals were 1.69 (95% CI 1.41 to 2.03) times more likely to be injured in the past year. Despite their convictions of increasing their own safety behaviour and that of others, injury prevention professionals' knowledge and training did not help them prevent their own injuries.

    Lung injury is a major clinical concern after hepatic ischemia-reperfusion (I/R), due to the production of reactive oxygen species in the reperfused liver. We investigated the efficacy of edaravone, a potent free-radical scavenger, for attenuating lung injury after hepatic I/R. Adult male Sprague-Dawley rats were assigned to sham + normal saline (NS), I/R + NS, or I/R + edaravone group. Rats in the I/R groups were subjected to 90 min of partial hepatic I/R. Five minutes before reperfusion, 3 mg/kg edaravone was administered to the I/R + edaravone group. After 6 h of reperfusion, we evaluated lung histopathology and wet-to-dry ratio. We also measured malondialdehyde (MDA), an indicator of oxidative stress, in the liver and the lung, as well as cytokine messenger RNA expressions in the reperfused liver and plasma cytokine concentrations. Histopathology revealed lung damages after 6 h reperfusion of partial ischemic liver. Moreover, a significant increase in lung wet-to-dry ratio was observed. MDA concentration increased in the reperfused liver, but not in the lungs. Edaravone administration attenuated the lung injury and the increase of MDA in the reperfused liver. Edaravone also suppressed the reperfusion-induced increase of interleukin-6 messenger RNA expressions in the liver and plasma interleukin-6 concentrations. Edaravone administration before reperfusion of the ischemic liver attenuates oxidative stress in the reperfused liver and the subsequent lung injury. Edaravone may be beneficial for preventing lung injury induced by hepatic I/R. Copyright © 2015 Elsevier Inc. All rights reserved.

    The Lysholm Knee Score (LKS) is widely used and is one of the most effective questionnaires employed to assess knee injuries. Although LKS has been translated into multiple languages, there is no Chinese version even though China has the largest population of patients with knee-joint injuries. The objective of our study was to develop the Chinese version of LKS (C-LKS) and assess its reliability, validity and responsiveness in Chinese patients with anterior cruciate ligament (ACL) injuries. Study participants were mainly recruited among patients with ACL injuries scheduled for arthroscopic ACL reconstruction at our hospital. First, we developed the C-LKS in a five-step translation and cross-cultural adaptation procedure. Next, we calculated the Cronbach's alpha, intraclass correlation coefficient (ICC), Pearson's correlation coefficient (r), effect size (ES), and standardized response mean (SRM) to evaluate the reliability, validity, and responsiveness of C-LKS respectively. Overall, 126 patients with ACL injuries successfully completed the questionnaires. Acceptable internal consistency (Cronbach's alpha = 0.726) as well as excellent test-retest reliability (ICC = 0.935) was found for C-LKS. Good or moderate correlation (r = 0.514-0.837) was determined among C-LKS and International Knee Documentation Committee Subjective Knee Form (IKDC), Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), physical subscales of SF-36; C-LKS also had fair or moderate correlation (r = 0.207-0.462) with the other subscales of SF-36, which adequately illustrated that good validity was included in C-LKS. In addition, good responsiveness was also observed in C-LKS (ES = 1.36,SRM = 1.26). We have shown that our developed C-LKS questionnaire is reliable, valid and responsible for the evaluation of Chinese-speaking patients with ACL injuries and it would be an effective instrument.

    2017-11-01

    Both, hamstring and ACL injuries are among the most typical injuries, particularly in change of direction and high speed running sports. They're also difficult to treat. Therefore, in the past few years, sports medicine practitioners and exercise scientists have mainly been focusing on the development and implementation of preventive programs in order to reduce the number of lower limb injuries, mainly by improving knee alignment. A number of studies have been able to prove the success of these training interventions, which are mainly addressing sensorimotor abilities and plyometric activities. The number of non-contact hamstring injuries has nevertheless been on the rise, particularly in sports like soccer and football. Therefore, the purpose of the following article is to introduce the hypothesis that the above-mentioned training interventions have a massive influence on the activation patterns on the targeted muscle group, and on the M. biceps femoris in particular. Muscle function and the resulting internal load are directly related to muscle architecture at the insertion. Training induced adaptations in hamstring activation patterns can thus lead to an increased injury susceptibility. In this case, a simulation model that directly relates to an acute deceleration maneuver provides valuable insights into the function of the biceps femoris muscle, especially when the rate of activity and the muscle geometry at the insertion area are taken into consideration. We conclude that there needs to be a greater individualization of prevention programs, especially in regards to anatomical requirements, in order to further reduce injury rates in elite sports. Moreover, it would also seem reasonable to apply a similar approach to aspects of chronic pain such as chronic non-specific low back pain. Copyright © 2017 Elsevier Ltd. All rights reserved.

    Conclusion: Due to an absence of published literature in Sudan, much of the data have been recorded from paper records and empirical observations. Prehospital care and injury prevention in the Sudan is a recent initiative, but it is developing into a promising model with many opportunities for improvement. This momentum should be nurtured and requires a purposive, collective collaboration to draw a blueprint for a locally relevant, effective and efficient prehospital system in Sudan. It is hoped that this article will highlight and encourage further progress.

  20. Prediction and Prevention of Acute Kidney Injury after Cardiac Surgery

    2016-01-01

    Full Text Available The incidence of acute kidney injury after cardiac surgery (CS-AKI ranges from 33% to 94% and is associated with a high incidence of morbidity and mortality. The etiology is suggested to be multifactorial and related to almost all aspects of perioperative management. Numerous studies have reported the risk factors and risk scores and novel biomarkers of AKI have been investigated to facilitate the subclinical diagnosis of AKI. Based on the known independent risk factors, many preventive interventions to reduce the risk of CS-AKI have been tested. However, any single preventive intervention did not show a definite and persistent benefit to reduce the incidence of CS-AKI. Goal-directed therapy has been considered to be a preventive strategy with a substantial level of efficacy. Many pharmacologic agents were tested for any benefit to treat or prevent CS-AKI but the results were conflicting and evidences are still lacking. The present review will summarize the current updated evidences about the risk factors and preventive strategies for CS-AKI.

    To determine the feasibility of evaluating medial knee joint laxity with dynamic magnetic resonance (MR) imaging and simultaneous physical joint examination in a large-bore 1.5-T system. The study included 10 patients (5 women, 5 men; mean age 35 years) with clinically diagnosed and categorized acute injuries of the medial collateral ligament (MCL). Intermittent valgus stress was applied separately to both the affected and the contralateral knee joint during dynamic MR imaging with a two-dimensional fast low-angle shot sequence. The width of the medial joint space and the opening angle between the femoral condyles and the tibial plateau were measured. Results obtained from dynamic MR imaging of the affected knee were compared with morphological MCL changes on static MRI, to kinematics of the contralateral side and to the clinical grading of MCL injuries. On clinical examination, all patients had grade 2 MCL injuries except one, who had a grade 1 lesion. Using morphological MRI criteria, 9 grade II and 1 grade III injuries were seen. Mean medial joint space width and opening angles of all affected knees were 2.8 mm and 2.7 respectively, compared with 1.7 mm and 2.1 on the contralateral side. The Wilcoxon signed rank test indicated that the differences in width (P = 0.005) and opening angle (P = 0.037) between the affected and contralateral knees were significant. Dynamic MR imaging and simultaneous physical joint examination is feasible. Our results suggest that this technique might enable the imaging documentation of medial ligamentous knee instability.

    The importance of the preseason physical examination and preparticipation evaluation of sports candidates is highlighted because it constitutes one of the few occasions in which the physician can actively prevent sports injuries from occurring. As exercise participation continues to increase on a world-wide basis, an understanding of the goals and objectives of such a pre-exercise evaluation are important. The need is not for a standard evaluation form, but for a consistent understanding of adjusting the evaluation to the age of the candidate, the type of sport to be engaged in and the anticipated level of competition. Essentials of any evaluation are musculoskeletal, cardiovascular and psychological examinations. Examinations should have clearly defined objectives, and factors determining the type of evaluation include: prospective athlete; contemplated exercise programme; and motivation. Different types of implementation are individual examinations, locker room technique and the station technique, each with advantages and disadvantages. A pre-exercise evaluation should always occur before any anticipated change in level of school or competition with an interval or intercurrent history and physical examinations occurring at regular intervals. It is important that examinations take place before the commencement of a sports season so previous injuries and problems can be dealt with; timing is vital. Contents of a pre-exercise physical examination should include history, a physical examination, laboratory testing and additional specific screening evaluations. Finally, assessment of the pre-exercise evaluation and injury prediction will aid physicians in preparticipation evaluations.

    This study presents a systematic approach-assessment of child injury prevention policies (A-CHIPP)-to assess and track policies on effective child injury interventions at the national level. Results from an initial pilot test of the approach in selected countries are presented. A literature review was conducted to identify conceptual models for injury policy assessment, and domains and indicators were proposed for assessing national injury policies for children aged 1-9 years. The indicators focused on current evidence-supported interventions targeting the leading external causes of child injury mortality globally, and were organised into a self-administered A-CHIPP questionnaire comprising 22 questions. The questionnaire was modified based on reviews by experts in child injury prevention. For an initial test of the approach, 13 countries from all six WHO regions were selected to examine the accuracy, usefulness and ease of understanding of the A-CHIPP questionnaire. Data on the A-CHIPP questionnaire were received from nine countries. Drowning and road traffic injuries were reported as the leading causes of child injury deaths in seven of these countries. Most of the countries lacked national policies on interventions that address child injuries; supportive factors such as finance and leadership for injury prevention were also lacking. All countries rated the questionnaire highly on its relevance for assessment of injury prevention policies. The A-CHIPP questionnaire is useful for national assessment of child injury policies, and such an assessment could draw attention of stakeholders to policy gaps and progress in child injury prevention in all countries. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

    Faga, Teresa; Pisani, Antonio; Michael, Ashour

    2014-01-01

    It is well known that iodinated radiographic contrast media may cause kidney dysfunction, particularly in patients with preexisting renal impairment associated with diabetes. This dysfunction, when severe, will cause acute renal failure (ARF). We may define contrast-induced Acute Kidney Injury (AKI) as ARF occurring within 24–72 hrs after the intravascular injection of iodinated radiographic contrast media that cannot be attributed to other causes. The mechanisms underlying contrast media nephrotoxicity have not been fully elucidated and may be due to several factors, including renal ischaemia, particularly in the renal medulla, the formation of reactive oxygen species (ROS), reduction of nitric oxide (NO) production, and tubular epithelial and vascular endothelial injury. However, contrast-induced AKI can be prevented, but in order to do so, we need to know the risk factors. We have reviewed the risk factors for contrast-induced AKI and measures for its prevention, providing a long list of references enabling readers to deeply evaluate them both. PMID:25197639

    Inline skating belongs like ice hockey, rugby, and boxing to sporting activities with high-risk of suffering tooth accidents. Because of high velocity and loss of balance, especially on uneven ground, the injury potential in inline skating is higher. The objective of this work was to conduct a comparative study between Switzerland and Germany. The questions focussed on the frequency of tooth accidents, their prevention by mouthguard and the level of information about emergency measures after dental trauma and the resulting consequences for athletes. Using a standardized questionnaire totally 612 individuals, 324 men and 288 women, in two countries belonging to three different divisions (fun, fitness and speed) were surveyed. Fifty-six (9.2%) of these 612 interviewees have already experienced a tooth injury while inline skating. More than half of all interviewed players (68.3%) were aware of the possibility of replanting avulsed teeth. Only 32.4% were familiar with the tooth rescue kit. Just 65.4% knew mouthguard and only 1.9% of those athletes (n = 12) wore a mouthguard while inline skating. The results show that the area of inline skating requires more information about preventing dental trauma through sports associations and dentists.

    Whilst the sport of softball has achieved worldwide popularity over the last 100 years, a consideration of the scientific principles underpinning softball is in its infancy. It is clear that the various motor skills associated with softball, such as pitching, batting and fielding, place considerable perceptual and physical demands upon players. Each of these skill categories are examined in more detail by reviewing the biomechanical principles associated with skilled performance. For pitching, a certain amount of information can be gleaned from baseball research; however, the underarm technique required by softball places the highest loads on the arm and shoulder during the accelerative, downward phase of the swing. Kinematic analyses of the bat swing suggest that elite batters have approximately 200 ms to decide whether to swing, and approximately the same duration to complete the swing (resulting in reported bat speeds of up to 40 m/sec). The research conducted on fielding has been limited to a consideration of throwing styles adopted in games. A variety of throwing techniques are adopted in the course of a typical game but elite players commonly adopt a sidearm technique when returning to base as quickly as possible. Data obtained from the National Athletic Training Association indicate a similar level of injury incidence in softball as in baseball. Approximately 17% of injuries are experienced by the pitcher and approximately 25% of all injuries are located in the forearm/wrist/hand joint segments. Sports science and sports medicine research have the potential to contribute significantly to performance enhancement and injury prevention in the future.

    The effectiveness of legislative intervention in the New Zealand market for children's nightclothes as an injury prevention strategy has been reassessed by examining those hospital admissions for the period 1980-8 (with emphasis on the 1985-8 period) in which clothing and/or nightclothes were involved. The profiles of the production of children's nightclothes (1977-86) and domestic heating (1984-8) were also examined. Ninety-five cases of burn injury discharges were identified (1985-8), and of those cases involving clothing 42% involved nightwear (49% 1981-4). Some of the 27% unspecified cases may have also involved nightwear (23%, 1981-4). A very strong linear downward trend for nightwear incidents was noted (chi 2 slope = 31.06, p less than 0.001). Forty-eight percent of cases involved children aged 1-6 years, and 68% involved pajamas. Stoves were the main specified ignition agent for nightclothes (36%). Open fires as a form of household heating decreased from 49% to 34% of households (1984-8). Estimated production of nightdresses in New Zealand also decreased (460,000 to 80,000 units, 1973-86). The pronounced decrease in injuries attributable to ignition of children's nightclothes is likely to be the result of mandatory controls on children's nightclothes, increased use of pyjamas, and a steady decrease in use of open fires and portable electric heaters. The typical injury event portrayed to the public of a girl in front of a heater or open fire needs to be corrected.

    In this case report an incumbent firefighter partially ruptured his right Achilles tendon during a study of the physical demands of firefighting. Kinematics and kinetics of the lower limbs and trunk were collected while the firefighter performed two simulated fire ground tasks. From this unexpected event, two insights were obtained that should be considered in all future injury prevention and reporting efforts. (i) Consider the full anatomical linkage--the right ankle and knee kinematics leading up to the onset of injury trial were comparable to all preceding repetitions. However, there was a notable difference in the left knee starting position before the initiation of movement of the 37th hose-advance trial. (ii) Consider the cumulative load--the task in question comprised forward and backward phases. A marked difference was observed in the frontal-plane ankle moment during the return phase of the trial preceding the injury. Additionally, the magnitude of the left side vertical ground reaction force was comparable across all trials, suggesting that loads experienced by the right limb were also similar. This would indicate that the tolerance of the Achilles tendon and not the magnitude of the loading was altered. The unfortunate injury captured in this work provides insight into the complexity of characterizing the pathways of injury. It is recommended that future injury prevention and reporting efforts consider individuals' physical demands (at work and in life) and document the nature of loading (i.e., frequency, duration, magnitude, type) when considering the mechanism for injury.

    Full Text Available Abstract Background Traumatic chondral lesions of the knee are common in football and rugby players. The diagnosis is often confirmed by arthroscopy which can be therapeutic by performing microfracture. Prospective information about the clinical results after microfracture is still limited. Aim To evaluate the short-term outcome of microfractured lesions in professional football ad rugby players in terms of healing and ability to return to play. Methods Twenty-four consecutive professional male players with isolated full-thickness articular cartilage defects on weight-bearing surface of femoral condyles were treated with microfracture. Clinical assessment of healing was done at three, six, 12 and at 18 months by using modified Cincinnati subjective and objective functional scoring. All 24 subjects were periodically scanned by 3-Tesla MRI on the day of the clinical evaluations and scored by the Henderson MRI classification for cartilage healing. A second look arthroscopy was carried out in 10 players five to seven months after surgery to evaluate lesion healing by using ICRS scoring system. This was done due to presence of discrepancy between a "normal" MRI and persistent clinical symptoms. Results This study showed that 83.3% of players' resume full training between five to seven months (mean: 6.2 after microfracture of full-thickness chondral lesions of weight-bearing surface of the knee. Function and MRI knee scores of the 24 subjects gradually improved over 18 months, and showed good correlation in assessing healing after microfracture at six, 12 and 18 months (r2 = 0.993, 0.986 and 0.993, respectively however, the second look arthroscopy score proved to have stronger strength of association with function score than MRI score.

    2012-03-01

    Sport and recreational activities are the leading cause of injury in youth, yet there is increasing evidence that many sport-related injuries are preventable. For injury prevention strategies to be effective, individuals must understand, adopt and adhere to the recommended prevention strategy or programme. Despite the recognized importance of a behavioural approach, the inclusion of behavioural change strategies in sport injury prevention has been historically neglected. The purpose of this commentary is to outline the rationale for the inclusion and application of behavioural science in reducing the burden of injury by increasing adherence to proven prevention strategies. In an effort to provide an illustrative example of a behavioural change approach, the authors suggest a specific plan for the implementation of a neuromuscular training strategy to reduce the risk of lower limb injury in youth sport. Given the paucity of evidence in the sport injury prevention setting, and the lack of application of theoretical frameworks to predicting adoption and adherence to injury preventive exercise recommendations in youth sport, data from the related physical activity promotion domain is utilized to describe how sound, theory-based injury prevention exercise interventions in youth may be developed. While the question of how to facilitate behavioural change and optimize adherence to preventive exercise recommendations remains an ongoing challenge, the authors detail several strategies based on two prominent behavioural theories to aid the reader in conceptualizing, designing and implementing effective interventions. Despite the minimal application of behavioural theory within the field of sport injury prevention in youth, behavioural science has the potential to make a significant impact on the understanding and prevention of youth sport injury. Appropriate evaluation of adherence and maintenance components based on models of behavioural change should be a critical

    This paper presents the results of 50 patients with trauma of the knee submitted to magnetic resonance imaging in the period of January 1996 to December 1997. The appearance and incidence of the main bone lesions were evaluated and correlated with the mechanisms of aggression and with clinical data. Associated lesions were also evaluated. Bone contusions were the most commonly findings encountered and were observed in 38 patients (76%). Osteochondral fractures occurred in five patients (10%) and bone fractures were detected in five patients (10%), of which two were associated with contusions in other adjoining bone compartments. Chondromalacia of the patella was observed only in two patients (4%). We concluded that magnetic resonance imaging is the imaging method of choice for the diagnosis of bone lesions in patients with trauma of the knee. (author)

    Whether knee instability contributes to the increased risk of falls and fractures observed in persons with knee osteoarthritis (OA) has not been studied. We examined the association of knee buckling with the risk of falling and fall-related consequences in older adults with, or at high risk for, knee OA. At the 60-month visit of the Multicenter Osteoarthritis Study, men and women ages 55-84 years were asked about knee buckling in the past 3 months and whether they fell when a knee buckled. Falls and fall-related injuries in the past 12 months and balance confidence were assessed at 60 and 84 months. Multivariate logistic regression was used to assess the association of knee buckling with falls and their consequences. A total of 1,842 subjects (59% women, mean ± SD age 66.9 ± 7.8 years, and body mass index 30.3 ± 5.7) were included. At 60 months 16.8% reported buckling and at 84 months 14.1% had recurrent (≥2) falls. Bucklers at 60 months had a 1.6- to 2.5-fold greater odds of recurrent falls, fear of falling, and poor balance confidence at 84 months. Those who fell when a knee buckled at baseline had a 4.5-fold, 2-fold, and 3-fold increased odds 2 years later of recurrent falls, significant fall injuries, and fall injuries that limited activity, respectively, and were 4 times more likely to have poor balance confidence. Interventions that reduce knee buckling may help prevent falls, fall-related injuries, and adverse psychological consequences of falls in persons with knee OA. © 2016, American College of Rheumatology.

    Objectives Whether knee instability contributes to the increased risk of falls and fractures observed in persons with knee osteoarthritis (OA) has not been studied. We examined the association of knee buckling with the risk of falling and fall-related consequences in older adults with, or at high risk for, knee OA. Methods At the 60 month visit of the Multicenter Osteoarthritis Study, men and women ages 55 to 84 were asked about knee buckling in the past 3 months and whether they fell when a knee buckled. Falls and fall-related injuries in the past 12 months and balance confidence were assessed at 60 and 84 months. Multivariate logistic regression was used to assess the association of knee buckling with falls and their consequences. Results 1,842 subjects (59% women, mean [SD] age= 66.9 [7.8] and BMI= 30.3 [5.7]) were included. At 60 months 16.8% reported buckling and at 84 months 14.1% had recurrent (≥2) falls. Bucklers at 60 months had a 1.6 to 2.5-fold greater odds of recurrent falls, fear of falling and poor balance confidence at 84 months. Those who fell when a knee buckled at baseline had a 4.5-fold, 2-fold and 3-fold increased odds two years later of recurrent falls, significant fall injuries and fall injuries that limited activity, respectively, and were 4 times more likely to have poor balance confidence. Conclusion Interventions that reduce knee buckling may help prevent falls, fall-related injuries and adverse psychological consequences of falls in persons with knee OA. PMID:26853236

    Childhood injuries are the leading cause of death in children and result in significant healthcare utilization. Injuries specifically related to all terrain vehicles, trampolines and scooter usage can be devastating and are often preventable. Our understanding of how and why these injuries occur can aid in preventing morbidity and mortality. The popularity of all-terrain vehicles, nonmotorized scooters and trampolines has soared over recent years. This increased usage has led to a tremendous rise in injuries in children utilizing these recreational activities. Many of the injuries occur in younger children who may not possess the motor and cognitive skills necessary to safely engage in these activities. These activities lead to a number of head and extremity injuries, most of which can be attenuated by the use of protective gear such as helmets and protective padding. Understanding the nature of these injuries can lead to advocacy and hopefully legislation to prevent further injuries from occurring.

    Clinical measurement. To translate and culturally adapt the Lower Extremity Functional Scale (LEFS) into a Brazilian Portuguese version, and to test the construct and content validity and reliability of this version in patients with knee injuries. There is no Brazilian Portuguese version of an instrument to assess the function of the lower extremity after orthopaedic injury. The translation of the original English version of the LEFS into a Brazilian Portuguese version was accomplished using standard guidelines and tested in 31 patients with knee injuries. Subsequently, 87 patients with a variety of knee disorders completed the Brazilian Portuguese LEFS, the Medical Outcomes Study 36-Item Short-Form Health Survey, the Western Ontario and McMaster Universities Osteoarthritis Index, and the International Knee Documentation Committee Subjective Knee Evaluation Form and a visual analog scale for pain. All patients were retested within 2 days to determine reliability of these measures. Validation was assessed by determining the level of association between the Brazilian Portuguese LEFS and the other outcome measures. Reliability was documented by calculating internal consistency, test-retest reliability, and standard error of measurement. The Brazilian Portuguese LEFS had a high level of association with the physical component of the Medical Outcomes Study 36-Item Short-Form Health Survey (r = 0.82), the Western Ontario and McMaster Universities Osteoarthritis Index (r = 0.87), the International Knee Documentation Committee Subjective Knee Evaluation Form (r = 0.82), and the pain visual analog scale (r = -0.60) (all, Pcoefficient = 0.957) of the Brazilian Portuguese version of the LEFS were high. The standard error of measurement was low (3.6) and the agreement was considered high, demonstrated by the small differences between test and retest and the narrow limit of agreement, as observed in Bland-Altman and survival-agreement plots. The translation of the LEFS into a

    A previous analysis of National Vital Statistics System data for 2003-2007 that examined disparities in rates of motor vehicle-related death by race/ethnicity and sex found that death rates for American Indians/Alaska Natives were two to four times the rates of other races/ethnicities. To address the disparity in motor vehicle-related injuries and deaths among American Indians/Alaska Natives, CDC funded four American Indian tribes during 2004-2009 to tailor, implement, and evaluate evidence-based road safety interventions. During the implementation of these four motor vehicle-related injury prevention pilot programs, seat belt and child safety seat use increased and alcohol-impaired driving decreased. Four American Indian/Alaska Native tribal communities-the Tohono O'odham Nation, the Ho-Chunk Nation, the White Mountain Apache Tribe, and the San Carlos Apache Tribe-implemented evidence-based road safety interventions to reduce motor vehicle-related injuries and deaths. Each community selected interventions from the Guide to Community Preventive Services and implemented them during 2004-2009. Furthermore, each community took a multifaceted approach by incorporating several strategies, such as school and community education programs, media campaigns, and collaborations with law enforcement officers into their programs. Police data and direct observational surveys were the main data sources used to assess results of the programs. Results included increased use of seat belts and child safety seats, increased enforcement of alcohol-impaired driving laws, and decreased motor vehicle crashes involving injuries or deaths. CDC's Office of Minority Health and Health Equity selected the intervention analysis and discussion as an example of a program that might be effective for reducing motor vehicle-related injury disparities in the United States. The Guide to Community Preventive Services recognizes these selected interventions as effective; this report examines the

    Objective: To evaluate the diagnostic accuracy of magnetic resonance imaging (MRI) of the knee. Materials and methods: Seventy-two patients have been submitted to MRI previously to arthroscopy of the knee performed by a single surgeon and utilized as a comparative standard method. Sensitivity, specificity, values of likelihood and rate of interobserver agreement have been evaluated. Results: The kappa agreement coefficient between MRI and arthroscopy was very good for lesions in the anterior cruciate ligament (0.84), good for lateral meniscus (0.75), reasonable for medial meniscus (0.50) and poor for chondral lesions (< 0.50). MRI has demonstrated high sensitivity for tears in the anterior cruciate ligament (94%) and in the medial meniscus (92%), good sensitivity for lesions in the lateral meniscus (80%), and low sensitivity for lesions in all of the chondral zones (< 50%), while the specificity has been excellent for all the chondral, and ligamentous structures, besides the lateral menisci analyzed (more than 97%), and reasonable (65%) for the medial meniscus. Conclusion: MRI is an useful tool in the clinical diagnosis of intra-articular knee lesions, as already demonstrated by similar results reported both in the Brazilian and international literature.

    Full Text Available Background and Objectives: Coronectomy is a relatively new method to prevent the risk of Inferior Alveolar Nerve (IAN injury during removal of lower third molars with limited scientific literature among Nepalese patients. Thus, a study was designed to evaluate coronectomy regarding its use, outcomes and complications.Materials and Methods: A descriptive study was conducted from December 2012 to December 2013 among patients attending Department of Oral and Maxillofacial Surgery, College of Dental Sciences, BP Koirala Institute of Health Sciences, Dharan, Nepal for removal of mandibular third molars. After reviewing the radiograph for proximity of third molar to the IAN, coronectomy was advised. A written informed consent was obtained from the patients and coronectomy was performed. Patients were recalled after one week. The outcome measures in the follow-up visit were primary healing, pain, infection, dry socket, root exposure and IAN injury. The prevalence of IAN proximity of lower third molars and incidence of complications were calculated.Results: A total 300 mandibular third molars were extracted in 278 patients during the study period. Out of 300 impacted mandibular third molar, 41 (13.7% showed close proximity to inferior alveolar nerve . The incidence of complications and failed procedure was 7.4% among the patients who underwent coronectomy. During the follow up visit, persistent pain and root exposure was reported while other complications like inferior alveolar nerve injury, dry socket and infection was not experienced by the study patients.Conclusion: With a success rate of 92.6% among the 41 patients, coronectomy is a viable alternative to conventional total extraction for mandibular third molars who have a higher risk for damage to the inferior alveolar nerve.JCMS Nepal. 2015;11(3:1-5.

    To investigate the effect of RugbySmart, a nationwide educational injury prevention programme, on the frequency of spinal cord injuries. Ecological study. New Zealand rugby union. Population at risk of injury comprised all New Zealand rugby union players. From 2001, all New Zealand rugby coaches and referees have been required to complete RugbySmart, which focuses on educating rugby participants about physical conditioning, injury management, and safe techniques in the contact phases of rugby. Numbers of all spinal injuries due to participation in rugby union resulting in permanent disablement in 1976-2005, grouped into five year periods; observed compared with predicted number of spinal injuries in 2001-5. Eight spinal injuries occurred in 2001-5, whereas the predicted number was 18.9 (relative rate=0.46, 95% confidence interval 0.19 to 1.14). Only one spinal injury resulted from scrums over the period; the predicted number was 9.0 (relative rate=0.11, 0.02 to 0.74). Corresponding observed and predicted rates for spinal injuries resulting from other phases of play (tackle, ruck, and maul) were 7 and 9.0 (relative rate=0.83, 0.29 to 2.36). The introduction of the RugbySmart programme coincided with a reduction in the rate of disabling spinal injuries arising from scrums in rugby union. This study exemplifies the benefit of educational initiatives in injury prevention and the need for comprehensive injury surveillance systems for evaluating injury prevention initiatives in sport.

    Bilateral carotid artery occlusion of 10 min followed by reperfusion for 24 hr was employed in present study to produce ischaemia and reperfusion induced cerebral injury in mice. Cerebral infarct size was measured using triphenyltetrazolium chloride staining. Short-term memory was evaluated using elevated plus maze. Inclined beam walking test was employed to assess motor incoordination. Bilateral carotid artery occlusion followed by reperfusion produced cerebral infarction and impaired short-term memory, motor co-ordination and lateral push response. A preceding episode of mesenteric artery occlusion for 15 min and reperfusion of 15 min (remote mesenteric ischaemic preconditioning) prevented markedly ischaemia-reperfusion-induced cerebral injury measured in terms of infarct size, loss of short-term memory, motor coordination and lateral push response. Glibenclamide (5 mg/kg, iv) a KATP channel blocker and caffeine (7 mg/kg, iv) an adenosine receptor blocker attenuated the neuroprotective effect of remote mesenteric ischaemic preconditioning. It may be concluded that neuroprotective effect of remote mesenteric ischaemic preconditioning may be due to activation of adenosine receptors and consequent activation of KATP channels in mice.

    Adolescent female football and handball players are among the athletes with the highest risk of sustaining anterior cruciate ligament (ACL) injuries. This study evaluated the effects of evidence-based lower extremity injury prevention training on neuromuscular and biomechanical risk factors for non-contact ACL injury. 40 adolescent female football and handball players (15-16 years) were randomly allocated to a control group (CON, n=20) or neuromuscular training group (NMT, n=20). The NMT group performed an injury prevention programme as a warm-up before their usual training 3 times weekly for 12 weeks. The CON group completed their regular warm-up exercise programme before training. Players were tested while performing a side cutting movement at baseline and 12-week follow-up, using surface electromyography (EMG) and three-dimensional movement analysis. We calculated: (1) EMG amplitude from vastus lateralis (VL), semitendinosus (ST) and biceps femoris 10 ms prior to initial contact (IC) normalised to peak EMG amplitude recorded during maximal voluntary isometric contraction and (2) VL-ST EMG preactivity difference during the 10 ms prior to foot contact (primary outcome). We measured maximal knee joint valgus moment and knee valgus angle at IC. There was a difference between groups at follow-up in VL-ST preactivity (43% between-group difference; 95% CI 32% to 55%). No between-group differences were observed for kinematic and kinetic variables. A 12-week injury prevention programme in addition to training and match play in adolescent females altered the pattern of agonist-antagonist muscle preactivity during side cutting. This may represent a more ACL-protective motor strategy. Published by the BMJ Publishing Group Limited.

    2012-09-01

    Full Text Available Abstract Background The emphasis on prevention in English health policy continues to centre predominantly on major diseases such as coronary heart disease and diabetes. A number of key documents detailing self-management techniques and prevention of osteoarthritis (OA are currently available, including the NICE guidelines and the Arthritis Foundation’s National Public Health Agenda for Osteoarthritis. However, few investigations have explored preventative knowledge of knee OA amongst the population. In particular, asymptomatic members of the population may use further information in considering how to prevent knee pain. This study considers perceptions around the prevention of knee pain amongst an asymptomatic population; this target population may provide alternative insights by which to stimulate preventative behaviours. Methods A sample of thirteen patients with no current knee pain was selected from responders to a population survey. Each interview was tape recorded and fully transcribed. Qualitative computer software package NVivo8 was used to manage the data. Thematic analysis was conducted using the constant comparative method. Results The definition and causes of knee pain were interpreted in a multitude of ways. The importance of prevention was recognised by a sub-set, while a small proportion of participants negated the role of prevention. A range of social factors, including early adoption of actions, influenced the implementation and continuation of preventative behaviours. Individual responsibility for prevention was a key theme, although the role of society was also considered. Exercise was cited as a principal preventative strategy, although some participants viewed exercise as a destructive activity. A number of participants deemed pharmacotherapy to be harmful and at odds with normal physiology, instead preferring to adopt preventative behaviour over medication usage. Conclusions This asymptomatic population exhibit

    Trifiletti, L B; Gielen, A C; Sleet, D A; Hopkins, K

    2005-06-01

    Behavioral and social sciences theories and models have the potential to enhance efforts to reduce unintentional injuries. The authors reviewed the published literature on behavioral and social science theory applications to unintentional injury problems to enumerate and categorize the ways different theories and models are used in injury prevention research. The authors conducted a systematic review to evaluate the published literature from 1980 to 2001 on behavioral and social science theory applications to unintentional injury prevention and control. Electronic database searches in PubMed and PsycINFO identified articles that combined behavioral and social sciences theories and models and injury causes. The authors identified some articles that examined behavioral and social science theories and models and unintentional injury topics, but found that several important theories have never been applied to unintentional injury prevention. Among the articles identified, the PRECEDE PROCEED Model was cited most frequently, followed by the Theory of Reasoned Action/Theory of Planned Behavior and Health Belief Model. When behavioral and social sciences theories and models were applied to unintentional injury topics, they were most frequently used to guide program design, implementation or develop evaluation measures; few examples of theory testing were found. Results suggest that the use of behavioral and social sciences theories and models in unintentional injury prevention research is only marginally represented in the mainstream, peer-reviewed literature. Both the fields of injury prevention and behavioral and social sciences could benefit from greater collaborative research to enhance behavioral approaches to injury control.

    2015-04-11

    Home healthcare is one of the fastest growing sectors in the United States. Percutaneous injuries from sharp medical devices (sharps) are a source of bloodborne pathogen infections among home healthcare workers and community members. Sharps use and disposal practices in the home are highly variable and there is no comprehensive analysis of the system of sharps procurement, use and disposal in home healthcare. This gap is a barrier to effective public health interventions. The objectives of this study were to i) identify the full range of pathways by which sharps enter and exit the home, stakeholders involved, and barriers for using sharps with injury prevention features; and ii) assess the leverage points for preventive interventions. This study employed qualitative research methods to develop two systems maps of the use of sharps and prevention of sharps injuries in home healthcare. Twenty-six in-depth interview sessions were conducted including home healthcare agency clinicians, public health practitioners, sharps device manufacturers, injury prevention advocates, pharmacists and others. Interview transcripts were audio-recorded and analyzed thematically using NVIVO qualitative research analysis software. Analysis of supporting archival material also was conducted. All findings guided development of the two maps. Sharps enter the home via multiple complex pathways involving home healthcare providers and home users. The providers reported using sharps with injury prevention features. However, home users' sharps seldom had injury prevention features and sharps were commonly re-used for convenience and cost-savings. Improperly discarded sharps present hazards to caregivers, waste handlers, and community members. The most effective intervention potential exists at the beginning of the sharps systems maps where interventions can eliminate or minimize sharps injuries, in particular with needleless treatment methods and sharps with injury prevention features

    Jump landing is a complex movement in sports. While competing and practicing, athletes frequently perform multi-planar jump landing. Anticipatory muscle activity could influence the amount of knee flexion and prepare the knee for dynamic weight bearing such as landing tasks. The aim of the present study was to examine knee muscle function and knee flexion excursion as athletes naturally performed multi-direction jump landing. Eighteen male athletes performed the jump-landing test in four directions: forward (0°), 30° diagonal, 60° diagonal, and lateral (90°). Muscles tested were vastus medialis (VM), vastus lateralis (VL), rectus femoris (RF), semitendinosus (ST), and biceps femoris (BF). A Vicon(TM) 612 workstation collected the kinematic data. An electromyography was synchronized with the Vicon(TM) Motion system to quantify dynamic muscle function. Repeated measure ANOVA was used to analyze the data. Jump-landing direction significantly influenced (P jump landing. A higher risk of knee injury might occur during lateral jump landing than forward and diagonal directions. Athletes should have more practice in jump landing in lateral direction to avoid injury. Landing technique with high knee flexion in multi-directions should be taught to jumpers for knee injury prevention.

    Casals, Martí; Finch, Caroline F

    2017-12-01

    Sports science and medicine need specialists to solve the challenges that arise with injury data. In the sports injury field, it is important to be able to optimise injury data to quantify injury occurrences, understand their aetiology and most importantly, prevent them. One of these specialty professions is that of Sports Biostatistician. The aim of this paper is to describe the emergent field of Sports Biostatistics and its relevance to injury prevention. A number of important issues regarding this profession and the science of sports injury prevention are highlighted. There is a clear need for more multidisciplinary teams that incorporate biostatistics, epidemiology and public health in the sports injury area. Published by the BMJ Publishing Group Limited.

    2012-09-01

    Policy strategies for injury and violence prevention influence systems development, organizational change, social norms, and individual behavior to improve the health and safety of a population. Injury and violence prevention professionals should consider how their issues resonate with various audiences, including policy makers, the public, and other decision makers. As the cost of healthcare continues to rise and greater demands are placed on the healthcare system, the use of public health policy becomes increasingly critical to protect the public's health and prevent injury and violence and its related morbidities and disabilities (Degutis, 2011). This article highlights some impactful policy successes from the field, allows us to reflect on the Injury Center's 20th anniversary, and describes steps to address injuries and violence into the future. The purpose of this paper is to discuss policy as a public health strategy and the critical role it plays in injury and violence prevention. Published by Elsevier Ltd.

    Proximal tibia fractures are associated with concurrent collateral ligament injuries. Failure to recognize these injuries may lead to chronic knee instability. The purpose of this study was to identify risk factors for concurrent collateral ligament injuries with proximal tibia fractures and their association with inpatient outcomes. A total of 32,441 patients with proximal tibia fractures were identified in the 2011-2012 National Trauma Data Bank. A total of 1445 (4.5%) had collateral ligament injuries, 794 (2.4%) had injuries to both collateral ligaments, 456 (1.4%) had a medial collateral ligament injury only, and 195 (0.6%) had a lateral collateral ligament injury only. On multivariate analysis, risk factors found to be associated with collateral ligament injuries included distal femur fracture (odds ratio, 2.1), pedestrian struck by motor vehicle (odds ratio, 2.0), obesity (odds ratio, 1.6), young age (odds ratio, 1.9 for 18 to 29 years vs 40 to 49 years), motorcycle accident (odds ratio, 1.5), and Injury Severity Score of 20 or higher (odds ratio, 1.4). In addition, patients with simultaneous injuries to both collateral ligaments had higher odds of inpatient adverse events (odds ratio, 1.51) and longer hospital stay (mean, 2.27 days longer). The risk factors reported by this study can be used to identify patients with proximal tibia fractures who may warrant more careful and thorough evaluation and imaging of their knee collateral ligaments.

    Excessive knee abduction loading is a contributing factor to anterior cruciate ligament (ACL) injury risk. The purpose of this study was to determine whether a double-leg landing training program with real-time visual feedback improves frontal-plane mechanics during double- and single-leg landings. Knee abduction angles and moments and vertical ground reaction forces (GRF) of 21 recreationally active women were quantified for double- and single-leg landings before and after the training program. This program consisted of two sessions of double-leg jump landings with real-time visual feedback on knee abduction moments for the experimental group and without real-time feedback for the control group. No significant differences were found between training groups. In comparison with pre-training data, peak knee abduction moments decreased 12% post-training for both double- and single-leg landings; whereas peak vertical GRF decreased 8% post-training for double-leg landings only, irrespective of training group. Real-time feedback on knee abduction moments, therefore, did not significantly improve frontal-plane knee mechanics during landings. The effect of the training program on knee abduction moments, however, transferred from the double-leg landings (simple task) to single-leg landings (more complex task). Consequently, ACL injury prevention efforts may not need to focus on complex tasks during which injury occurs. © 2013 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    Unintentional injuries (injuries for which there is no evidence of a predetermined intent) are one of the leading causes of death worldwide, particularly in low- and middle-income countries (LMICs). Although evidence demonstrates unintentional injuries are preventable it is a public health challenge for many LMICs such as the Solomon Islands. Occupational therapists are well placed to contribute to injury prevention, as they have specialised skills to analyse the accessibility and safety of the environments within which people conduct their daily occupations. While the role of occupational therapy in unintentional injury prevention is well known in high-income countries, it is unfamiliar in LMICs, especially in the Solomon Islands. This integrative review aimed to explore the incidence of common unintentional injuries, and the burden in the Solomon Islands; and explore the potential role of occupational therapy in unintentional injury prevention in the Solomon Islands, based on current activities in LMICs. Articles were reviewed from six databases (Medline, CINAHL, OTDBase, OT Seeker, Scopus and PsychInfo). Five articles met the inclusion criteria for the first objective and 15 articles met the inclusion criteria for the second objective. These articles were thematically analysed where themes and codes associated with the research objectives were extracted and analysed. Unintentional injuries in the Solomon Islands reported in the literature included ocular trauma, falls from fruit trees and coconut palms, and road traffic crashes. Burden of injury reported was mostly associated with loss of productivity. Occupational therapists undertook rehabilitative, biomechanical, neurodevelopmental and educational roles in LMIC, focusing on tertiary and secondary injury prevention. This integrative review suggests that there is limited information regarding injury in the Solomon Islands. However, evidence is available in LMICs to suggest that occupational therapy services can

    Full Text Available Introduction. Posterior knee joint dislocation associated with injury of the popliteal artery in children is an extremely rare condition. Rapid diagnosis and treatment are essential for limb salvage and function. Case report. We reported a 14-year-old boy who suffered traumatic displacement of the right knee and contusion of the popliteal artery during motorcycle accident. The diagnosis was confirmed using Doppler and duplex ultrasonography and digital substraction transfemoral arteriography. The urgent surgical procedure was performed using posterior approach to the popliteal artery. During the surgical exploration, rupture of the posterior cruciate ligament associated with thrombosed popliteal artery have been found. The damaged popliteal artery was resected and replaced with autologous saphenous vein graft. The last stage of the procedure was a transosseous femoral fixation of posterior circuate ligament. A 3-year-follow-up after the surgery demonstrated intact arterial perfusion and very good function of the knee with a minimal difference as compared with the contralateral knee. Conclusion. Combined orthopedic and vascular injuries are very rare in children. They require combined treatment. [Projekat Ministarstva nauke Republike Srbije, br. 175008

  19. The role of accident theory in injury prevention - time for the pendulum to swing back.

    2012-01-01

    Injury prevention is a branch of safety sciences. While comprehensive theoretical developments occurred in the wider field in the last decades, little of these developments reached and influenced the injury prevention community. Instead, a clear retro trend 'back to basics' is seen among injury prevention scholars, especially to Dr William Haddon's pioneering work some 50 years ago. This paper intends to draw attention to this polarisation and discuss possible explanations. It is argued that the strong campaign against the accident concept among leading injury prevention groupings became a serious hindrance for theoretical exchange. The underlying process is interpreted in terms of a struggle for ownership over this truly interdisciplinary field of research, unfortunately at the expense of theoretical stagnation in injury prevention circles and lessened interest in collaboration from other scientific areas. This paper is written as a tribute to Professor Leif Svanström and his scientific contributions, with special regard to his genuine interest in interdisciplinary research.

    Oxidative stress plays an important role in cadmium-induced liver injury. Nuclear factor erythroid 2-related factor 2 (Nrf2) is a transcription factor that up-regulates cytoprotective genes in response to oxidative stress. To investigate the role of Nrf2 in cadmium-induced hepatotoxicity, Nrf2-null mice, wild-type mice, kelch-like ECH-associated protein 1-knockdown (Keap1-KD) mice with enhanced Nrf2, and Keap1-hepatocyte knockout (Keap1-HKO) mice with maximum Nrf2 activation were treated with cadmium chloride (3.5 mg Cd/kg, i.p.). Blood and liver samples were collected 8 h thereafter. Cadmium increased serum alanine aminotransferase (ALT) and lactate dehydrogenase (LDH) activities, and caused extensive hepatic hemorrhage and necrosis in the Nrf2-null mice. In contrast, Nrf2-enhanced mice had lower serum ALT and LDH activities and less morphological alternations in the livers than wild-type mice. H 2 DCFDA (2′,7′-dichlorodihydrofluoresein diacetate) staining of primary hepatocytes isolated from the four genotypes of mice indicated that oxidative stress was higher in Nrf2-null cells, and lower in Nrf2-enhanced cells than in wild-type cells. To further investigate the mechanism of the protective effect of Nrf2, mRNA of metallothionein (MT) and other cytoprotective genes were determined. Cadmium markedly induced MT-1 and MT-2 in livers of all four genotypes of mice. In contrast, genes involved in glutathione synthesis and reducing reactive oxygen species, including glutamate-cysteine ligase (Gclc), glutathione peroxidase-2 (Gpx2), and sulfiredoxin-1 (Srxn-1) were only induced in Nrf2-enhanced mice, but not in Nrf2-null mice. In conclusion, the present study shows that Nrf2 activation prevents cadmium-induced oxidative stress and liver injury through induction of genes involved in antioxidant defense rather than genes that scavenge Cd. -- Highlights: ► Cadmium caused extensive hepatic hemorrhage and necrosis in Nrf2-null mice. ► Keap1-KD and Keap1-HKO mice were

    Objectives: To examine the published evidence on interventions to prevent softball related injuries among adults, and to encourage more epidemiologic research as a foundation for future softball injury prevention efforts. Methods: The authors reviewed literature identified from six electronic databases for studies on softball related injuries. The search was limited to studies written in the English language, published between 1970 and 2002, and involving adult populations. Research was excluded that evaluated baseball ("hard ball") related injuries or was aimed at injury treatment. Identified studies were categorized by study design. Intervention/prevention papers were evaluated further and described in detail. Results: The search strategy identified 39 studies specifically related to softball. Most studies were case reports/case series (n = 13) or descriptive studies (n = 11); only four were analytic or intervention/prevention studies. Studies collected data in a variety of ways, often without denominator data to permit calculation of injury rates. Studies also did not differentiate between slow or fast pitch softball activities and most did not mention the type of softball that was used. Conclusions: Surprisingly few studies exist on interventions to reduce injuries during softball, one of the most popular recreational sports in the US. Of the existing literature, much attention has been on sliding related injuries, which comprise only a segment of softball injuries. Basic epidemiologic studies describing the nature, severity, and risk factors for softball injuries in a variety of populations are needed, followed by additional intervention evaluation studies aimed at modifiable risk factors.

    The aim of this retrospective study was to determine the effectiveness of a work injury prevention program in the housekeeping department of a hotel. Studies have validated the use of different injury prevention strategies to decrease the incidence of work-related injuries. Few studies, however, have reported the efficacy of an on-site work injury prevention program by a physical therapist. In 1995, implementation of a work injury prevention program by a physical therapist to 50 housekeeping supervisors, 60 house persons and 340 guest room attendants at a large hotel began. This program included a detailed work risk analysis of the work environment, development of job descriptions, identification of injury-related problematic work situations, and implementation of a job specific supervisor-training program. Supervisor, house person and guest room attendant training was also conducted at the end of 1995 and the beginning of 1997. Data of injury reports in 1995, 1996, and 1997 were analyzed to determine the results of the program. There was a reduction in total injury claims, total medical expenses, total lost work time and total restricted duty time. These results demonstrate the cost effectiveness of implementing a work injury prevention program for housekeeping guest room attendants in the hotel industry. Copyright 2004 IOS Press

  7. Prevention of deep vein thrombosis after total knee arthroplasty. Coumadin versus pneumatic calf compression.

    Hodge, W A

    1991-10-01

    The rate of deep vein thrombosis (DVT) after total knee arthroplasty (TKA) without prophylaxis has been reported as high as 84%. Coumadin anticoagulation and pneumatic calf compression (PCC) boots are two current therapies that have been thought to be effective in reducing this high rate of DVT. To investigate these two methods, a nonrandomized prospective study was designed. The first group involved treating 48 consecutive knee arthroplasties with a regimen of coumadin anticoagulation. The second group involved 81 consecutive knee arthroplasties treated with sequential PCC boots. Bilateral lower extremity venography was performed between the eighth and tenth hospital postoperative days. The overall incidence of DVT in the coumadin group was 33%, with 29% having calf thrombi and 6% having thigh thrombi. The overall incidence of DVT in the boot group was 31%, with 27% having calf thrombi and 6% having thigh thrombi. In both groups, there were no treatment-related complications. Cost analysis of the administration of each type of therapy showed coumadin to be approximately 50% more expensive than PCC boots. Although coumadin and PCC boot therapy are safe and effective in reducing the incidence of DVT after TKA, there are economic factors that make the latter a more favorable option.

    2005-09-01

    Patients undergoing total hip and knee arthroplasty are at increased risk for the development of venous thromboembolic disease, and there is general agreement that these patients require prophylaxis. The selection of a prophylactic agent involves a balance between efficacy and safety and often needs to be individualized for specific patients and institutions. Despite extensive research, the ideal agent for prophylaxis against deep venous thrombosis has not been identified. The results of randomized trials indicate that low-molecular-weight heparin, warfarin, and fondaparinux are the most effective prophylactic agents after total hip arthroplasty and that low-molecular-weight heparin, warfarin, fondaparinux, and pneumatic compression boots are the most effective agents after total knee arthroplasty. The duration of prophylaxis against deep venous thrombosis after total hip and knee arthroplasty remains controversial. Prophylaxis should be continued beyond hospital discharge. In the future, the determination of the duration of prophylaxis will be based on the risk stratification of individual patients. The practice of discharging patients from the hospital without prophylaxis, even when the decision is based on negative results of procedures that screen for the presence of deep venous thrombosis, is not cost-effective.

    2012-12-01

    Injuries are a major adverse event during a soccer player's career; they require medical and surgical treatment and rehabilitation and thus may interrupt the player's activity, often with severe physical and psychological sequel. Specialists have tried to identify the risk factors for injuries, in an attempt to discover predictors that could be prevented and or eliminated before the injury occurs, but the results are scarce. This article reviews the epidemiology of the frequency and occurrence of injuries in Italian soccer players, reports a list of preventable risk factors that are associated with injuries, and identifies preventable risk factors. We have identified personal factors (age, previous traumatic events, physical and biological characteristics of the player, life style habits such as smoking, alcohol, and diet, changes in physical-athletic aspects of the players, such as increased muscle strength, and use of medications) as possible risk factors for injuries. However, environmental factors such as changes in training techniques, field composition, and shoes structure may also have a major influence. This summary indicates that appropriate preventive measures can be undertaken to prevent injuries in professional soccer players. Professionals who are in close contacts with the players should be informed of the predictors of injuries and should be trained to intervene and plan appropriate preventive measures.

    Conclusion: The ACL injury in this study occurred during the first 30% of the delivery phase, most likely during the first 25% of the delivery phase. A stiff landing of the left leg with a small knee flexion angle was the primary contributor to this injury. Javelin throwers may have a soft left leg landing with a flexed knee, which may help them prevent ACL injuries without compromising performance.

    Knee rehabilitation after total knee replacement arthroplasty is essential for patients during their post-surgery recovery period. This study is about designing one degree of freedom knee rehabilitation equipment to assist patients for their post-surgery exercise. The equipment is designed to be used in sitting position with flexion/extension of knee in sagittal plane. The range of knee joint motion is starting from 0 to 90 degrees angle for knee rehabilitation motion. The feature includes adjustable link for different human proportions and the torque feedback control at knee joint during rehabilitation and the control of flexion/extension speed. The motion of the rehabilitation equipment was set to move at low speed (18 degrees/sec) for knee rehabilitation. The rehabilitation link without additional load took one second to move from vertical hanging up to 90° while the corresponding torque increased from 0 Nm to 2 Nm at 90°. When extra load is added, the link took 1.5 seconds to move to 90° The torque is then increased from 0 Nm to 4 Nm. After a period of time, the speed of the motion can be varied. User can adjust the motion to 40 degrees/sec during recovery activity of the knee and users can increase the level of exercise or motion up to 60 degrees/sec to strengthen the muscles during throughout their rehabilitation program depends on each patient. Torque control is included to prevent injury. Patients can use the equipment for home exercise to help reduce the number of hospital visit while the patients can receive an appropriate therapy for their knee recovery program.

    To investigate the role of eccentric knee flexor strength, between-limb imbalance and biceps femoris long head (BFlh) fascicle length on the risk of future hamstring strain injury (HSI). Elite soccer players (n=152) from eight different teams participated. Eccentric knee flexor strength during the Nordic hamstring exercise and BFlh fascicle length were assessed at the beginning of preseason. The occurrences of HSIs following this were recorded by the team medical staff. Relative risk (RR) was determined for univariate data, and logistic regression was employed for multivariate data. Twenty seven new HSIs were reported. Eccentric knee flexor strength below 337 N (RR=4.4; 95% CI 1.1 to 17.5) and possessing BFlh fascicles shorter than 10.56 cm (RR=4.1; 95% CI 1.9 to 8.7) significantly increased the risk of a HSI. Multivariate logistic regression revealed significant effects when combinations of age, history of HSI, eccentric knee flexor strength and BFlh fascicle length were explored. From these analyses the likelihood of a future HSI in older athletes or those with a HSI history was reduced if high levels of eccentric knee flexor strength and longer BFlh fascicles were present. The presence of short BFlh fascicles and low levels of eccentric knee flexor strength in elite soccer players increases the risk of future HSI. The greater risk of a future HSI in older players or those with a previous HSI is reduced when they have longer BFlh fascicles and high levels of eccentric strength.

    Full Text Available INTRODUCTION: Soccer is classified as a high to moderate-intensity contact sport. It is therefore of importance that the incidence of soccer injuries be reduced through preventive interventions. The purpose of this review is to conclude the importance of a prevention program and explore the role parents have towards minimizing soccer related injuries among children and adolescence football players.METHOD: 42 hand searches, 5 books, and 25 electronic articles were reviewed and relevant results were collected for the purpose of this paper. Selected studies were categorized as follows: soccer injury statistics, injury prevention program, and parents and prevention.RESULTS: 5-16 year of age is a critical age range for soccer related injuries. Some studies have confirmed soccer injuries can be reduced by preventive interventions, and mentioned the importance of prevention program and the role of parents in the program. A few studies reported the efficacy for a positive parent-child relationship and injury prevalence, while other reported the negative influence parental demand on injury rates among children. Moreover, suggestions were made of consideration to parents prior to allowing children to participate in soccer.CONCLUSIONS: Prevention of sports injuries is team work, and parent's role can be as vital as other members of the prevention team. In a successful preventive program, there are steps that parents can take to help kids stay safe on the soccer field or wherever they play or participate in sports activities. Educational materials should be provided to parents by soccer camp organizers before children involve in soccer programs.

  20. Public Health Models for Preventing Child Maltreatment: Applications From the Field of Injury Prevention.

    Contemporary approaches to child protection are dominated by individualized forensically focused interventions that provide limited scope for more holistic preventative responses to children at risk and the provision of support to struggling families and communities. However, in many jurisdictions, it is frequently shown, often through public inquiries and program reviews, that investigatory and removal approaches are failing in critically important ways, particularly regarding reducing the inequities that underpin neglect and abuse. Consequently, there have been increasing calls for a public health model for the protection of children, although there is often a lack of clarity as to what exactly this should entail. Yet, there are opportunities to learn from public health approaches successfully used in the field of injury prevention. Specifically, we advocate for the use of Haddon's Matrix, which provides a detailed theoretical and practical framework for the application of a comprehensive and integrated public health model to guide intervention program design and responses to child protection risk factors. A broad overview of the application of Haddon's Matrix's principles and methods is provided with examples of program and intervention design. It is argued that this framework provides the range of interventions necessary to address the complex social and structural factors contributing to inequity and the maltreatment of children. It also provides the foundation for a holistic and integrated system of prevention and intervention to contribute to system-level change and address child maltreatment. © The Author(s) 2016.

  1. Surgical Tip for Prevention of Lip Injury During Orthognathic and Facial Bone Contouring Surgery.

    Iatrogenic lip injury is a rather common complication after facial bone surgery, but is usually treated lightly by the surgeon compared with other more severe functional complications. However, these injuries can have permanent sequelae and can therefore be a reason for patient dissatisfaction, especially after cosmetic surgery. Intraoperative lip injuries during facial bone surgery are usually caused by heat-generating surgical instruments or forced traction on the operative fields. The authors have applied a special technical strategy using a hydrocolloid dressing material to avoid these intraoperative lip injuries. This method does not disturb the operative procedure itself, but efficiently prevents lip injuries and decreases surgical morbidities and postoperative swelling.

    The complex structure of articular cartilage allows for diverse knee function throughout range of motion and weight bearing. However, disruption to the structural integrity of the articular surface can cause significant morbidity. Due to an inherently poor regenerative capacity, articular cartilage defects present a treatment challenge for physicians and therapists. For many patients, a trial of nonsurgical treatment options is paramount prior to surgical intervention. In instances of failed conservative treatment, patients can undergo an array of palliative, restorative, or reparative surgical procedures to treat these lesions. Palliative methods include debridement and lavage, while restorative techniques include marrow stimulation. For larger lesions involving subchondral bone, reparative procedures such as osteochondral grafting or autologous chondrocyte implantation are considered. Clinical success not only depends on the surgical techniques but also requires strict adherence to rehabilitation guidelines. The purpose of this article is to review the basic science of articular cartilage and to provide an overview of the procedures currently performed at our institution for patients presenting with symptomatic cartilage lesions.

  3. Lung injury in acute pancreatitis: mechanisms, prevention, and therapy.

    2012-02-03

    Lung injury is the most pertinent manifestation of extra-abdominal organ dysfunction in pancreatitis. The propensity of this retroperitoneal inflammatory condition to engender a diffuse and life-threatening lung injury is significant. Approximately one third of patients will develop acute lung injury and acute respiratory distress syndrome, which account for 60% of all deaths within the first week. The variability in the clinical course of pancreatitis renders it a vexing entity and makes demonstration of the efficacy of any specific intervention difficult. The distinct pathologic entity of pancreatitis-associated lung injury is reviewed with a focus on etiology and potential therapeutic maneuvers.

    Full Text Available Background: Epidemiologic research to learn the incidence, type, location, and severity of female soccer injuries and the risk factors for sustaining a sport injury is the first step in developing preventive policies. The aim of this study was to analyze the incidence of injuries in the population of female soccer players in Spain. Methods: The injuries incurred by 25,397 female soccer players were registered by the medical staff of the Spanish Football Federation during 1 season. A standardized medical questionnaire was used to classify the injury according to type, severity, location, and injury mechanism. A total of 2108 injuries was reported with an incidence of 0.083 injuries per player per season. Most injuries were in the lower limbs (74.0%, mainly affecting knee (30.4% and ankle joints (17.9%. Results: The proportion of injuries derived from contact with another player was higher during matches (33.7% than during training (11.4%; p  0.05. Conclusion: Most female soccer injuries were located at the knee and ankle; the injury mechanism determined the playing time lost; and the player's age did not affect injury characteristics.

  4. Development of a Comprehensive and Interactive Tool to Inform State Violence and Injury Prevention Plans.

    Science.gov (United States)

    Wilson, Lauren; Deokar, Angela J; Zaesim, Araya; Thomas, Karen; Kresnow-Sedacca, Marcie-Jo

    The Center of Disease Control and Prevention's Core State Violence and Injury Prevention Program (Core SVIPP) provides an opportunity for states to engage with their partners to implement, evaluate, and disseminate strategies that lead to the reduction and prevention of injury and violence. Core SVIPP requires awardees to develop or update their state injury and violence plans. Currently, literature informing state planning efforts is limited, especially regarding materials related to injury and violence. Presumably, plans that are higher quality result in having a greater impact on preventing injury and violence, and literature to improve quality would benefit prevention programming. (1) To create a comprehensive injury-specific index to aid in the development and revision of state injury and violence prevention plans, and (2) to assess the reliability and utility of this index. Through an iterative development process, a workgroup of subject matter experts created the Violence and Injury Prevention: Comprehensive Index Tool (VIP:CIT). The tool was pilot tested on 3 state injury and violence prevention plans and assessed for initial usability. Following revisions to the tool (ie, a rubric was developed to further delineate consistent criteria for rating; items were added and clarified), the same state plans were reassessed to test interrater reliability and tool utility. For the second assessment, reliability of the VIP:CIT improved, indicating that the rubric was a useful addition. Qualitative feedback from states suggested that the tool significantly helped guide plan development and communicate about planning processes. The final VIP:CIT is a tool that can help increase plan quality, decrease the research-to-practice gap, and increase connectivity to emerging public health paradigms. The tool provides an example of tailoring guidance materials to reflect academic literature, and it can be easily adapted to other topic areas to promote quality of strategic plans

    Limited research has explored pesticide injury prevention among American Indian farmers. In a five-year agricultural intervention, a university-community partnership, including the University of New Mexico School of Medicine, New Mexico State University, Shiprock Area Cooperative Extension Service, and Navajo Nation communities, used a culturally relevant model to introduce and maintain safe use of integrated pest management techniques. We applied the Diffusion of Innovations theory and community-based approaches to tailor health promotion strategies for our intervention. In a longitudinal study with repeated measures, we trained six "model farmers" to be crop management experts in pesticide safety, application, and control. Subsequently, these model farmers worked with 120 farm families randomized into two groups: intervention (Group 1) and delayed intervention (Group 2). Measurements included a walk-through analysis, test of knowledge and attitudes, and yield analysis. Both groups demonstrated improvements in pesticide storage behaviors after training. Test scores regarding safety practices improved significantly: from 57.3 to 72.4 for Group 1 and from 52.6 to 76.3 for Group 2. Group 1 maintained their knowledge and safety practices after the intervention. Attitudes about pesticides and communication of viewpoints changed across the study years. With pesticides and fertilizer, the number of corn ears increased by 56.3% and yield (kg m(-2)) of alfalfa increased by 41.2%. The study combined traditional farming practices with culturally relevant approaches and behavior change theory to affect knowledge, safety practices, attitudes, communication channels, and crop yield. Storage behaviors, use of pesticides and safety and application equipment, and safety practice knowledge changed significantly, as did attitudes about social networking, social support, and the compatibility and relative advantage of pesticides for farms.

    2015-12-01

    Taping is often used to manage the high rate of knee injuries in ballet dancers; however, little is known about the effect of taping on lower-limb biomechanics during ballet landings in the turnout position. This study investigated the effects of Kinesiotape (KT), Mulligan's tape (MT) and no tape (NT) on knee and hip kinetics during landing in three turnout positions. The effect of taping on the esthetic execution of ballet jumps was also assessed. Eighteen pain-free 12-15-year-old female ballet dancers performed ballet jumps in three turnout positions, under the three knee taping conditions. A Vicon Motion Analysis system (Vicon Oxford, Oxford, UK) and Advanced Mechanical Technology, Inc. (Watertown, Massa chusetts, USA) force plate collected lower-limb mechanics. The results demonstrated that MT significantly reduced peak posterior knee shear forces (P = 0.025) and peak posterior (P = 0.005), medial (P = 0.022) and lateral (P = 0.014) hip shear forces compared with NT when landing in first position. KT had no effect on knee or hip forces. No significant differences existed between taping conditions in all landing positions for the esthetic measures. MT was able to reduce knee and the hip forces without affecting the esthetic performance of ballet jumps, which may have implications for preventing and managing knee injuries in ballet dancers. © 2015 John Wiley & Sons A/S.
