    Full Text Available Hip arthroscopy is a safe method for treating a variety of pathological conditions that were unknown until a decade ago. Femoroacetabular impingement is the commonest of these pathological conditions and the one with the best results when treated early on. The instruments and surgical technique for hip arthroscopy continue to evolve. New indications for hip arthroscopy has been studied as the ligamentum teres injuries, capsular repair in instabilities, dissection of the sciatic nerve and repair of gluteal muscles tears (injuries to the hip rotator cuff, although still with debatable reproducibility. The complication rate is low, and ever-better results with fewer complications should be expected with the progression of the learning curve.

    Background Wrist arthroscopy plays a role in both the diagnosis and the treatment of wrist pathology. It has evolved in the last three decades. Questions The present status of wrist arthroscopy was investigated by answering the following questions: -What is its current position in the treatment wrist pathologies according to the literature? -What is its current position according to hand surgeons? Methods Analysis of the number of publications on wrist arthroscopy was performed and compared with the number of publications on other arthroscopy topics to assess the current position of wrist arthroscopy. The members of the EWAS (European Wrist Arthroscopy Society) and the members of eight national hand surgery societies were questioned on wrist arthroscopy in daily practice. Results From 1975 till now, 925 papers on wrist arthroscopy were found. The publications on wrist arthroscopy increased from an average of 8/year (1986) to 26/year (2012). More than half (56.9%) of the respondents of the EWAS perform fewer than 5 wrist arthroscopies per month, and only 7 (10.8%) indicate the performance of more than 10 wrist arthroscopies per month. Seventy-four percent of the orthopedic hand surgeons perform wrist arthroscopy (in 48.5% for therapeutic indications) against 36.8% of plastic surgery hand surgeons (in 23.1% for therapeutic indications). Conclusion Wrist arthroscopy has taken up a place in the armamentarium of the hand surgeon. The place of wrist arthroscopy in daily practice is related to the background of the hand surgeon.

    Since its introduction more than three decades ago, wrist arthroscopy has continually evolved. The procedure has a wide list of indications, including diagnostic and management applications. The scope of practice for the wrist arthroscopic surgeon includes management of triangulofibrocartilage complex pathology, evaluation and management of carpal instability, assistance in fracture reduction of the radius and scaphoid, treatment of trapeziometacarpal synovitis and arthritis, distal ulnar and carpal bone excisions, and salvage procedures. In addition, innovations such as new portals and smaller arthroscopes have expanded the applications of wrist arthroscopy. PMID:23118138

    Wrist arthroscopy is a commonly used procedure that has undergone many modifications and improvements since it was first described. The advent of new portals (both dorsal and volar) means that the wrist joint can be viewed from virtually any perspective ("box concept"). Indications for wrist arthroscopy have continued to expand and include diagnostic and reparative procedures and, more recently, reconstructive, soft-tissue, and bony procedures. Arthroscopic grading of Kienböck's disease better describes articular damage compared with plain radiographs and can help guide surgical treatment options. Triangular fibrocartilage complex injury diagnosis, classification, and treatment can be performed arthroscopically, including distal ulna resection (wafer procedure). Assessment of fracture reduction of the distal radius and scaphoid is superior to that obtained with fluoroscopy, with the advantage of being able to look for associated soft-tissue and chondral injuries. Arthroscopic assessment of intercarpal ligament injuries and instability is now considered the gold standard by many authors. Arthroscopy can also aid us in the management of post-traumatic capsular contraction, resection of ganglia, and the relatively rare isolated ulna styloid impaction. Complications of wrist arthroscopy are relatively uncommon. With the ever-expanding list of indications and procedures that can be performed with this technique, it exists as an essential diagnostic and therapeutic tool for the orthopaedic surgeon.

    It has become clear that the stability of the scapholunate joint does not depend wholly on the scapholunate interosseous ligament, but rather on both primary and secondary stabilizers, which form a scapholunate ligament complex. Each case of scapholunate instability is unique and should be treated with tissue-specific repairs, which may partly explain why one procedure cannot successfully restore joint stability in every case. Wrist arthroscopy has a pivotal role in both the assessment and treatment of the scapholunate ligament complex derangements. Tears of the foveal attachment of the triangular fibrocartilaginous complex can be an underdiagnosed cause of distal radioulnar joint instability, because the foveal fibers cannot be visualized using the standard radiocarpal arthroscopy portals. Distal radioulnar joint arthroscopy allows for direct visualization and assessment of these fibers, which in turn has spawned a number of open and arthroscopic repair methods. Wrist arthroscopy has gained wider acceptance as a method to fine-tune articular reduction during open and percutaneous fixation of distal radius fractures, and simplifies intra-articular osteotomies for malunion. It can facilitate percutaneous bone grafting of scaphoid nonunions and has a role in the diagnosis and treatment of associated soft tissue lesions. These and other recent developments will be discussed in the following article. PMID:22916867

    Small-joint arthroscopy has supplanted open procedures because it offers the potential for improvement in joint visualization, reduced scarring, and accelerated recovery. Despite these advantages, arthroscopy of the first metatarsophalangeal joint is not commonly performed and reports of its use are lacking. The reason for this is not clear but may be because of perceived technical complexity and poorly defined indications. In our experience, however, arthroscopy of the first metatarsophalangeal joint is a versatile procedure that facilitates treatment of many different pathologic processes through a minimally invasive approach with few complications. We present our technique for arthroscopic management of osteochondral lesions of the hallux. PMID:27656371

    Fluid extravasation is possibly the most common complication of shoulder arthroscopy. Shoulder arthroscopy can lead to major increases in the compartment pressure of adjacent muscles and this phenomenon is significant when an infusion pump is used. This article describes a case of pectoral swelling due to fluid extravasation after shoulder arthroscopy. A 24-year-old male underwent an arthroscopic Bankart repair for recurrent shoulder dislocation. The surgery was performed in the beach chair position and lasted two hours. At the end of the procedure, the patient was found to have left pectoral swelling. A chest radiography showed no abnormality. Pectoral swelling due to fluid extravasation after shoulder arthroscopy has not previously been documented. PMID:26889473

    Full Text Available CONTEXT: Rehabilitation following hip arthroscopy is an integral component of the clinical outcome of the procedure. Given the increase in quantity, complexity, and diversity of procedures performed, a need exists to define the role of rehabilitation following hip arthroscopy.OBJECTIVES: 1 To determine the current rehabilitation protocols utilized following hip arthroscopy in the current literature, 2 to determine if clinical outcomes are significantly different based on different post-operative rehabilitation protocols; and 3 to propose the best-available evidence-based rehabilitation program following hip arthroscopy.DATA SOURCES: Per PRISMA guidelines and checklist, Medline, SciVerse Scopus, SportDiscus, and Cochrane Central Register of Controlled Trials were searched.STUDY SELECTION: Level I-IV evidence clinical studies with minimum two-year follow-up reporting outcomes of hip arthroscopy with post-operative rehabilitation protocols described were included. DATA EXTRACTION: All study, subject, and surgery parameters were collected. All elements of rehabilitation were extracted and analyzed. Descriptive statistics were calculated. Study methodological quality was analyzed using the Modified Coleman Methodology Score (MCMS.RESULTS: 18 studies were included (2,092 subjects; 52% male, mean age 35.1 +/- 10.6 years, mean follow-up 3.2 +/- 1.0 years. Labral tear and femoroacetabular impingement were the most common diagnoses treated and labral debridement and femoral/acetabular osteochondroplasty the most common surgical techniques performed. Rehabilitation protocol parameters (weight-bearing, motion, strengthening, and return-to-sport were poorly reported. Differences in clinical outcomes were unable to be assessed given heterogeneity in study reporting. Time-, phase-, goal-, and precaution-based guidelines were extracted and reported.CONCLUSIONS: The current literature of hip arthroscopy rehabilitation lacks high-quality evidence to support a

    Full Text Available The purpose of this study is to correlate the findings of Magnetic Resonance Imaging with Arthroscopy in internal derangements of knee and to assess the sensitivity, specificity and accuracy of Magnetic Resonance Imaging in comparison to Arthroscopy. METHODS AND MATERIALS Fifty six patients with history of suspected internal derangement of knee were evaluated prospectively with MRI and correlated with arthroscopy during a one and half a year period from March 2012 to September 2013.1.5 Tesla MRI machine using a closed extremity coil is used. Sequences used in MRI of the knee include Turbo-spin echo (TSE, FFE (Gradient echo and Short Tau Inversion Recovery (STIR sequences in Axial, Sagittal and Coronal planes using a slice thickness of 3 mm with a 0.3 mm slice gap. Arthroscopy of the knee with standard anteromedial and anterolateral portals with the patient in supine position done in all the cases. RESULTS The diagnostic sensitivity, specificity and accuracy of MRI in detecting cruciate ligament and meniscal injuries as compared to Arthroscopy are as follows: Anterior Cruciate Ligament (ACL: 97.29%, 89.47%, 94.64%; Posterior Cruciate Ligament (PCL: 100%, 100%, 100%; Medial Meniscus (MM: 100%, 93.33%, 98.21% and Lateral Meniscus (LM: 93.10, 92.59, 92.85. Most common lesions found were ACL and Medial Meniscal tears (posterior horn of MM being the most common site. SUMMARY AND CONCLUSION  MRI is a useful non-invasive modality having high sensitivity, specificity and accuracy in diagnosing cruciate ligament and meniscal injuries.  MRI should be considered as the first line of investigation in all patients with suspected internal derangements of knee.  MRI being easily available and non-invasive is useful as a pre-operative screening modality, thus improves the quality of diagnostic and therapeutic arthroscopies and further reduces the morbidity.  Arthroscopy is the standard diagnosing tool in all patients with suspected internal

    Distal radius fractures are the most common fractures in humans and early surgical intervention with modern plating systems is becoming increasingly more established to avoid secondary dislocation. Even fractures with slight dislocations are adequately stabilized and the affinity for surgical intervention and plating procedures is applied to secure these simple fractures. In this aspect the surgical indications are significantly dependent on X-ray examination results. Further diagnostics with respect to ligamentous and soft tissue injury are the exception although the impact energy which creates osseus fractures is sufficient by far to destroy functional soft tissue, cartilage and ligaments. The ongoing development of wrist arthroscopy enables new possibilities especially concerning concomitant articular involvement of distal radius fractures. Arthroscopy-assisted reduction and stabilization as well as minimally invasive soft tissue repair and loose body removal seem to be adequate methods to improve the surgical treatment of distal radius fractures.

    Femoroacetabular impingement may be particularly disabling to the high-demand athlete, especially those with significant cutting and pivoting requirements. If nonoperative treatment fails to adequately alleviate symptoms or sufficiently restore function in the athlete, hip arthroscopy can lead to improved pain, improved range of motion, and high rates of return to play with proper postoperative rehabilitation. The rate of return to previous level of competition is also high with accurate diagnosis and well-executed correction of deformity. A clear understanding of the etiology, diagnosis, management, and outcomes is essential for clinicians to optimally help patients to return to play. PMID:27543404

    @@ Historical perspective It was well known that in 1918 Takagi performed the first arthroscopic inspection of a cadaver's knee in Japan. 1 His interest in this area laid the foundation for arthroscopy and facilitated the development of arthroscope. In 1931, Burman reported an experimental study on the arthroscopic exploration of cadaveric joints, but he believed that the ankle joint was unsuitable for such techniques because it was too narrow to pass through the posterior puncture.2Unexpectedly, several years later Takagi described a routine method for arthroscopic examination of the ankle.

  9. Isolated Pulmonary Embolism following Shoulder Arthroscopy

    Full Text Available Pulmonary embolism (PE following shoulder arthroscopy is a rare complication. We present a unique case report of a 43-year-old right-hand dominant female who developed a PE 41 days postoperatively with no associated upper or lower extremity DVT. The patient had minimal preoperative and intraoperative risk factors. Additionally, she had no thromboembolic symptoms postoperatively until 41 days following surgery when she developed sudden right-hand swelling, labored breathing, and abdominal pain. A stat pulmonary computed tomography (CT angiogram of the chest revealed an acute PE in the right lower lobe, and subsequent extremity ultrasounds showed no upper or lower extremity deep vein thrombosis. After a thorough review of the literature, we present the first documented isolated PE following shoulder arthroscopy. Although rare, sudden development of an isolated PE is possible, and symptoms such as sudden hand swelling, trouble breathing, and systemic symptoms should be evaluated aggressively with a pulmonary CT angiogram given the fact that an extremity ultrasound may be negative for deep vein thrombosis.

    From 1983 to 1990, 82 knee arthroscopies (8.2%) carried out in our patients found nothing pathological. Sixty-four percent of these patients were active in sports, but trauma was noted in 32% of the cases only. Football and other ball games, skiing, and track and field athletics were the main causes. Twenty-six percent of the patients had undergone previous surgery in the affected knee. At a mean of 4.6 years postoperatively, clinical and radiological re-assessment was conducted so as to compare our pre- and intraoperative findings with the further course of events. We found that 48.2% of the patients were symptom-free after the diagnostic arthroscopy, 37.5% had persistent discomfort and 14.3% had a recurrence of discomfort after 6 months to 2 years. The objective measurement score (Zarins Rowe score), at 47.5 out of 50 points, was better than the subjective score, at 40 out of 50 points. Our diagnoses had to be changed retrospectively: meniscal lesions were diagnosed too frequently, while chondropathia patellae and instability were often missed. Additionally, complaints could be related to abnormal axis, limited range of motion of the hip or knee, leg length inequality and hypermobility. Being unable to verify a presumed intra-articular lesion arthroscopically is frustrating for both doctor and patient. Our data suggest that meniscal signs should be looked at more critically and emphasise the need for a complete evaluation of the whole locomotor system.

  13. Valid MR imaging predictors of prior knee arthroscopy

    International Nuclear Information System (INIS)

    To determine whether fibrosis of the medial patellar reticulum (MPR), lateral patellar reticulum (LPR), deep medial aspect of Hoffa's fat pad (MDH), or deep lateral aspect of Hoffa's fat pad (LDH) is a valid predictor of prior knee arthroscopy. Institutional review board approval and waiver of informed consent were obtained for this HIPPA-compliant study. Initially, fibrosis of the MPR, LPR, MDH, or LDH in MR imaging studies of 50 patients with prior knee arthroscopy and 100 patients without was recorded. Subsequently, two additional radiologists, blinded to clinical data, retrospectively and independently recorded the presence of fibrosis of the MPR in 50 patients with prior knee arthroscopy and 50 without. Sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and accuracy for detecting the presence of fibrosis in the MPR were calculated. κ statistics were used to analyze inter-observer agreement. Fibrosis of each of the regions examined during the first portion of the study showed a significant association with prior knee arthroscopy (p < 0.005 for each). A patient with fibrosis of the MPR, LDH, or LPR was 45.5, 9, or 3.7 times more likely, respectively, to have had a prior knee arthroscopy. Logistic regression analysis indicated that fibrosis of the MPR supplanted the diagnostic utility of identifying fibrosis of the LPR, LDH, or MDH, or combinations of these (p ≥ 0.09 for all combinations). In the second portion of the study, fibrosis of the MPR demonstrated a mean sensitivity of 82%, specificity of 72%, PPV of 75%, NPV of 81%, and accuracy of 77% for predicting prior knee arthroscopy. Analysis of MR images can be used to determine if a patient has had prior knee arthroscopy by identifying fibrosis of the MPR, LPR, MDH, or LDH. Fibrosis of the MPR was the strongest predictor of prior knee arthroscopy. (orig.)

    To determine whether fibrosis of the medial patellar reticulum (MPR), lateral patellar reticulum (LPR), deep medial aspect of Hoffa's fat pad (MDH), or deep lateral aspect of Hoffa's fat pad (LDH) is a valid predictor of prior knee arthroscopy. Institutional review board approval and waiver of informed consent were obtained for this HIPPA-compliant study. Initially, fibrosis of the MPR, LPR, MDH, or LDH in MR imaging studies of 50 patients with prior knee arthroscopy and 100 patients without was recorded. Subsequently, two additional radiologists, blinded to clinical data, retrospectively and independently recorded the presence of fibrosis of the MPR in 50 patients with prior knee arthroscopy and 50 without. Sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and accuracy for detecting the presence of fibrosis in the MPR were calculated. {kappa} statistics were used to analyze inter-observer agreement. Fibrosis of each of the regions examined during the first portion of the study showed a significant association with prior knee arthroscopy (p < 0.005 for each). A patient with fibrosis of the MPR, LDH, or LPR was 45.5, 9, or 3.7 times more likely, respectively, to have had a prior knee arthroscopy. Logistic regression analysis indicated that fibrosis of the MPR supplanted the diagnostic utility of identifying fibrosis of the LPR, LDH, or MDH, or combinations of these (p {>=} 0.09 for all combinations). In the second portion of the study, fibrosis of the MPR demonstrated a mean sensitivity of 82%, specificity of 72%, PPV of 75%, NPV of 81%, and accuracy of 77% for predicting prior knee arthroscopy. Analysis of MR images can be used to determine if a patient has had prior knee arthroscopy by identifying fibrosis of the MPR, LPR, MDH, or LDH. Fibrosis of the MPR was the strongest predictor of prior knee arthroscopy. (orig.)

    Wrist arthroscopy can facilitate early definitive diagnosis of soft tissue, carpal bone cartilage, the triangular fibrocartilage complex and carpal ligaments injuries. Many such injuries can be treated successfully with minimally invasive arthroscopic techniques, reducing the morbidity associated with surgical exposure and permitting earlier return to work. Between November 1991 and May 1996 19 wrist arthroscopies were performed in the Department of Orthopedics and Trauma Surgery, University ...

    O'Holleran, James D; Altchek, David W

    2006-01-01

    The athlete's elbow has been described as one of the last frontiers in orthopaedic sports medicine. It has been considered separately from other athletic injuries because of the unique constellation of pathology that results from repetitive overhead throwing. Tremendous gains in understanding the complex interplay between the dynamic and static stabilizers of the athlete's elbow have occurred over the past decade. The desire to treat these injuries in a minimally invasive manner has driven the development of techniques and instrumentation for elbow arthroscopy, a successful and essential technique in the treatment of the thrower's elbow. Medial collateral ligament injuries, ulnar neuritis, valgus extension overload with osteophyte formation and posteromedial impingement, flexor pronator strain, medial epicondyle pathology, and osteochondritis dissecans of the capitellum have all been described as consequences of the overhead throwing motion. In addition, loose body formation, bony spur formation, and capsular contracture can each be present in conjunction with these conditions or as isolated entities. Not all pathology in the thrower's elbow is amenable to arthroscopic treatment; however, the clinician must be familiar with all of these conditions to form a comprehensive differential diagnosis for an athlete with elbow pain. The surgeon treating the athlete's elbow should be comfortable with both open and arthroscopic treatments. An understanding of the anatomy and biomechanics of the thrower's elbow is essential for good patient care. The preoperative evaluation should focus on a thorough history and physical examination, as well as specific diagnostic imaging modalities. PMID:16958443

    Full Text Available Objective: to evaluate the nature of unilateral spinal anesthesia using various modes of administration of low doses of hyperbaric bupivacaine. Materials and Methods. Prospectively, the randomized study included 56 patients undergoing knee arthroscopy. In the control group bupivacaine of 5mg was administered simultaneously, in the main group — fractionally by 2.5 mg. The development of thermal and pain blocks from different sides was investigated. The data were statistically processed. Results. In the control group, the positioning of the patient usually began after the entire dose of anesthetic had been administered. In the case of temperature paresthesia in the area of the sacral segments of the full anesthesia throughout underlying limb was not always achieved. In 6 cases of block was not sufficient. In the main group patient positioning was performed after the administration of 2.5 mg of anesthetic and evaluate temperature paresthesia and in 2 cases the total dose was increased to 7.5 mg. The successful development of sensory block at fractional administration was significantly higher than in the single-step introduction. Conclusion. Temperature paresthesia occurs within the first minute and is an early predictor of developing spinal anesthesia. The area of arising paresthesia shows preferential distribution of the anesthetic. In the application of low dose local anesthetic the desired upper level of anesthesia via the patient positioning and dose adjustment may be achieved.

    Objectives: Assess the worthiness of arthroscopy in investigating and treating knee pain after arthroplasty unexplained by clinical and subsidiary examinations. Methods: Among 402 patients submitted to total or unicompartimental arthroplasty between September 2001 and April 2007 at a public university hospital, 17 presented with pain on prosthetic articulation, without clear diagnosis by clinical, X-ray, laboratory, scintiscan, or nuclear magnetic resonance tests. All patients were submitted to arthroscopy and symptoms were assessed by using the Lysholm scale, comparing pre-and post-arthroscopy periods. Peroperative findings have been recorded. Results: The procedure was effective for pain relief in 14 of 17 patients (82.35%). The median for Lysholm scale climbed from 36 points before arthroscopy to 94 points after the procedure (p < 0.001). Most of the patients (12) were arthroscopically diagnosed with fibrosis known as “cyclop”; on the remaining five patients, anterior synovitis was found. All patients were treated by resection. Conclusions: Knee arthroscopy after arthroplasty in patients presenting unclear persistent pain shows localized arthrofibrosis (“cyclops”) or synovitis, which can be treated by using the same procedure, resulting in pain relief.

    The traditional method of surgical training has followed the 'observe, practice, and teach' model, which is useful for open surgery, but is insufficient for minimally invasive surgery. This study presents the validation of a new simulator designed for TMJ arthroscopy training. A group of 10 senior maxillofacial surgeons performed an arthroscopy procedure using the simulator. They then completed a questionnaire analyzing the realism of the simulator, its utility, and the educational quality of the audiovisual software. The mean age of the 10 surgeons was 42.6 years, and they had performed a mean 151 arthroscopies. With regard to the realism of the simulator, 80% reported that it was of an appropriate size and design and 70% referred to the very realistic positions and relationships between the internal structures. Regarding its educational potential, 80% reported the simulator to be very useful for acquiring the basic skills and to acquire the sensation of depth during access to the TMJ. Finally, 90% reported the prototype to be very useful for TMJ arthroscopy training. These preliminary results showed a high degree of approval. The general opinion of the group of experts was that the experience was rewarding and inspiring, and that the prototype has the educational potential for the achievement of basic TMJ arthroscopy skills.

  1. Post-arthroscopy septic arthritis: Current data and practical recommendations.

    2015-12-01

    Septic arthritis develops after less than 1% of all arthroscopy procedures. The clinical symptoms may resemble those seen after uncomplicated arthroscopy, raising diagnostic challenges. The diagnosis rests on emergent joint aspiration with microscopic smear examination and prolonged culturing on specific media. Urgent therapeutic measures must be taken, including abundant arthroscopic lavage, synovectomy, and the concomitant administration of two effective antibiotics for at least 6 weeks. Preservation of implants or transplants is increasingly accepted, and repeated joint lavage is a component of the treatment strategy. After knee arthroscopy, infection is the most common complication; most cases occur after cruciate ligament reconstruction, and staphylococci are the predominant causative organisms. Emergent synovectomy with transplant preservation and appropriate antibiotic therapy ensures eradication of the infection in 85% of cases, with no adverse effect on final functional outcomes. After shoulder arthroscopy, infection is 10 times less common than neurological complications and occurs mainly after rotator cuff repair procedures; the diagnosis may be difficult and delayed if Propionibacterium acnes is the causative organism. The update presented here is based on both a literature review and a practice survey. The findings have been used to develop practical recommendations aimed at improving the management of post-arthroscopy infections, which are exceedingly rare but can induce devastating functional impairments.

    Purpose: To review the current literature examining the relative merits of arthroscopy and MR imaging of the knee. Material and Methods: All papers comparing MR imaging with arthroscopy published within the last 10 years according to Medline were collected and read. Results: Technology has improved considerably during recent years allowing detailed non-invasive visualization of the knee. In particular, the development of cheaper whole-body and dedicated low-field MR units has opened up for non-invasive inspection of the knee at reasonable cost. Meniscal tears can be detected with accuracy rates of around 90% and rupture of the anterior cruciate ligament with accuracy rates of around 93% compared to arthroscopy. However, arthroscopy is not the ideal gold standard, since it has weak points, e.g. peripheral meniscal tears or osteochondritis without apparent damage to the cartilage. Conclusion: Based on the overwhelming literature it seems safe to conclude that MR examinations of the knee should be performed before arthroscopy is undertaken. (orig.).

  3. Hip arthroscopy in the setting of hip dysplasia

    2016-01-01

    Objective Hip arthroscopy in the setting of hip dysplasia is controversial in the orthopaedic community, as the outcome literature has been variable and inconclusive. We hypothesise that outcomes of hip arthroscopy may be diminished in the setting of hip dysplasia, but outcomes may be acceptable in milder or borderline cases of hip dysplasia. Methods A systematic search was performed in duplicate for studies investigating the outcome of hip arthroscopy in the setting of hip dysplasia up to July 2015. Study parameters including sample size, definition of dysplasia, outcomes measures, and re-operation rates were obtained. Furthermore, the levels of evidence of studies were collected and quality assessment was performed. Results The systematic review identified 18 studies investigating hip arthroscopy in the setting of hip dysplasia, with 889 included patients. Criteria used by the studies to diagnose hip dysplasia and borderline hip dysplasia included centre edge angle in 72% of studies but the range of angles were quite variable. Although 89% of studies reported improved post-operative outcome scores in the setting of hip dysplasia, revision rates were considerable (14.1%), with 9.6% requiring conversion to total hip arthroplasty. Conclusion The available orthopaedic literature suggests that although improved outcomes are seen in hip arthroscopy in the setting of hip dysplasia, there is a high rate of re-operation and conversion to total hip arthroplasty. Furthermore, the criteria used to define hip dysplasia vary considerably among published studies. Cite this article: M. Yeung, M. Kowalczuk, N. Simunovic, O. R. Ayeni.

    In an era during which minimally invasive procedures are increasingly becoming the norm, arthroscopy of the temporomandibular joint (TMJ) seems to be infrequently used for diagnosis and treatment of disorders of the TMJ. The reasons for this are not clear. The purpose of this study was to find out the current state of arthroscopy of the TMJ in the UK and, more specifically, how often it is used, the indications for its use, the level of experience of practising surgeons, and the reasons for not using it. Information was gathered between 2009 and 2010 from a postal and e-mail questionnaire to all oral and maxillofacial consultants in the UK. Of the 346 consultants, 215 (60%) responded to the questionnaire. Forty-two said that they currently used arthroscopy of the TMJ, and 33 of those (81%) have more than 5 years' experience. During the past year, a total of 8 consultants nationally have done 20 arthroscopies or more. Thirty-three of the procedures (81%) were done for both diagnosis and treatment. Lack of perceived need of patients and lack of interest in this specialty were the main reasons given for not doing arthroscopy, lack of training being a key secondary reason. The Storz and Olympus systems were the most commonly used within the UK. Results seem to support the opinion that arthroscopy of the TMJ is under-used, and consideration should be given to ensuring that trainees are instructed in its use, which is important in the diagnosis and treatment of disorders of the TMJ.

    Knee arthroscopy in a patient with undiagnosed chronic monoarticular arthritis revealed dark pigmentation of the snyovium; synovial biopsy revealed histologic and ultrastructural features characteristic of ochronosis. Synovial fluid (SF) was non-inflammatory, without pigmented shards of cartilage; calcium pyrophosphate dihydrate crystals were absent in both the SF and biopsy specimen. Homogentisic acid was detectable in the urine by thin layer chromatography, and asymptomatic spondylosis with intervertebral disc calcification was found. The negative family history, lack of mucocutaneous pigmentation and failure of the urine to spontaneously darken obscured the diagnosis, which was easily made by arthroscopy. PMID:6699824

    A specific desire to find new training methods arose from the new fields called 'minimal invasive surgery.' With the technical advance modern video arthroscopy became the standard procedure in the ORs. Holding the optical system with the video camera in one hand, watching the operation field on the monitor, the other hand was free to guide, e.g., a probe. As arthroscopy became a more common procedure it became obvious that some sort of special training was necessary to guarantee a certain level of qualification of the surgeons. Therefore, a hospital in Frankfurt, Germany approached the Fraunhofer Institute for Computer Graphics to develop a training system for arthroscopy based on VR techniques. At least the main drawback of the developed simulator is the missing of haptic perception, especially of force feedback. In cooperation with the Department of Electro-Mechanical Construction at the Darmstadt Technical University we have designed and built a haptic display for the VR arthroscopy training simulator. In parallel we developed a concept for the integration of the haptic display in a configurable way.

    Full Text Available Growing awareness of femoroacetabular impingement (FAI and recent innovations in management has resulted in hip arthroscopy becoming one of the fastest-growing orthopaedic subspecialties. The purpose of this study was to identify the 50 most cited articles related to the topic of FAI and hip arthroscopy and to analyze their characteristics.The overall number of citations within these articles ranged from 99 to 820. Citation density ranged from 4.41 to 74.55. Seven countries produced these articles with the majority attributed to the United States (n=26 and Switzerland (n=18. Clinical studies made up more than half of the top articles (n=27. The JBJS level of evidence most commonly encountered was level IV (n=24 while the remaining articles were level III (n=3. No randomized controlled trials or non-randomized controlled trials were encountered in this search. The level of evidence was not significantly correlated with the overall number of citations, publication year, or citation density. The current top 50 list provides orthopaedic surgeons interested in hip arthroscopy with anup-to-date core list of the most cited articles in the scientific literature and represents a foundation to use to develop their knowledge regarding hip arthroscopy and FAI.

  11. Arthroscopy of the wrist: anatomy and classification of carpal instability.

    Science.gov (United States)

    Cooney, W P; Dobyns, J H; Linscheid, R L

    1990-01-01

    Carpal instability can be defined as the lack of ligamentous and skeletal support adequate to maintain a wrist stable to external forces of pinch and grasp. This instability may be static or dynamic. It has been classified as (a) carpal instability, dissociated (CID), a situation in which one or more of the ligaments are torn, and (b) carpal instability, nondissociative (CIND), a situation in which the ligaments are intact but stretched. Carpal instability can also be the result of carpal bone malalignment from various causes. Arthroscopy can be particularly useful in assessing carpal instability, however arthrography with contrast medium, fluoroscopy, and stress loading should precede this arthroscopic assessment. Arthroscopy allows visualization of the volar radiocarpal and ulnocarpal ligaments of the wrist, and the arthroscopic examination can be combined with manual manipulation of the carpal bones to detect laxity of those ligaments, to examine stability of the scapholunate and lunotriquetral interosseous ligaments, and to show instability of the distal radioulnar joint.

    Ankle arthroscopy is an important diagnostic and therapeutic technique in the management of ankle disorders. Nowadays ankle arthroscopy provides good to excellent results (up to 90%) in the treatment of certain intra-articular disorders. Due to the superficial location of ankle joint and the abundance of overlying neurovascular structures, complications reported in ankle arthroscopy are greater than those reported in other joints. We present the first reported case of a complete division of the posterior tibial nerve during an anterior ankle arthroscopy combined with an additional posterolateral portal. This was due to a poorly controlled use of the arthroscopic instruments. PMID:27197613

    Hip arthroscopy is a fast growing orthopedic field of expertise. As in any field of surgery adequate postoperative pain management regimes are of utmost importance. The purpose of this review is to provide an overview of current knowledge on anesthetic options for perioperative pain management for hip arthroscopy. We searched the Pubmed/Medline and Embase database for literature and included 10 studies for our analysis. Because of the variety of pain scales and different ways of measured pain no meta-analysis could be performed and a descriptive review is performed. There are several types of pain regimens that can mostly be divided in two groups: local anesthetics and nerve blocks. Included studies show a rather large variation in reported visual analogue scale scores, post anesthesia care unit admission time and opioid usage. There are several anesthetic options available for hip arthroscopy. Different studies use different dosages, anesthetic regimens and different protocols; this partly explains the differences between studies with similar techniques. Peripheral nerve blocks seems promising but regarding current literature no clear recommendation can be made about what the best perioperative pain management option is, an overview of all reported techniques is given.

    2015-01-01

    Full Text Available Background and Aims: Shoulder arthroscopy requires fluid irrigation, which causes soft-tissue oedema around chest, neck, and arm intraoperatively, leading to postoperative airway complications. We decided to study the incidence of increase in the neck circumference in shoulder arthroscopy and its effects on the airway. Methods: We studied 32 cases of shoulder arthroscopies over a period of 1-year, performed under general anaesthesia with interscalene block. The neck circumference of patients before and after the procedure was measured along with other parameters. The endotracheal tube cuff was deflated at the end of surgery to determine air leak around the tube. The negative leak test suggested airway oedema. Results: Thirty out of 32 patients showed positive air leak test. The average change in neck circumference was 1.17 ± 1.16 cm and all could be extubated uneventfully. Two showed negative leak test with an increase in neck circumference by 4.5 and 6.4 cm and were not extubated. Multiple regression analysis for risk factors showed intraoperative hypertension as a single predictor for an increase in neck circumference. Conclusion: Change in the neck circumference beyond 4 cm may suggest airway compromise and below 4 cm, airway compromise is unlikely even in the presence of extensive soft-tissue oedema around the shoulder, upper arm and chest.

    2016-01-01

    Introduction Shoulder pain can cause significant pain, discomfort and reduce the ability to perform activities of daily living, thus making it the third most common cause of musculoskeletal consultation. The current gold standard diagnostic investigation is arthroscopy. MRI is a proved sensitive and accurate non-invasive tool in investigating shoulder pathology, but false and misleading results are equally reported. Aim The aim of the study is to compare the efficacy of MRI in diagnosing shoulder pathologies in comparison to arthroscopy, considering arthroscopy as the gold standard. Materials and Methods Thirty nine consecutive patients, between 18-80 years of age, presenting with chronic shoulder pain or instability of more than 6 weeks, or with clinical signs of impingement or tear were included in the study. MRI of the shoulder joint was done followed by shoulder arthroscopy. The data collected was analysed for the significant correlation between MRI of shoulder and arthroscopic findings by kappa statistics. Results Out of 39 patients, Rotator cuff (RC) tear was the most common pathology. MRI showed excellent sensitivity in the diagnosis of rotator cuff tears (0.91) and osteochondral defects (OCD), very good sensitivity for Bankart’s lesion (0.8) and had poor sensitivity to detect SLAP tear (0.15). MRI was specific for all shoulder pathologies. MRI detected RC tears with kappa score of 0.73, Bankart’s tear and OCD’s with kappa score of 0.83 and 1.0 respectively and SLAP lesion with kappa score of 0.14. The accuracy of MRI was highest in diagnosing OCD’s (1.0), followed by RC tear (0.9), Bankart’s tear (0.9) and accuracy was least in diagnosing SLAP lesion (0.7). False negative results were more than false positives. Conclusion The present study supports that MRI is effective in diagnosing rotator cuff tears, Bankart’s tear and ostechondral defects but was not found to be helpful in diagnosing SLAP lesions. MRI and arthroscopy have complimentary roles

    Arthroscopy of the knee was performed using 30 ml single dose intraarticular instillations of 0.5% or 0.25% solutions of bupivacaine (Marcaine). A total of 18 patients (mean age, 34 years), divided into two groups, participated in this study. Venous plasma levels were measured at 0, 10, 20, 30, 45, 60, 90, 120, and 240 minute intervals following a single instillation into the knee joint. All patients had suspected traumatic internal derangement of the knee. Electrocardiogram tracings, blood pressure, and neurologic assessment were monitored at each venous sampling interval or more often if clinically indicated. The type and amount of supplemental anesthesia were also recorded. None of our 18 patients required a general anesthetic because of pain although the following procedures were performed: meniscectomy, plica release, abrasion chondroplasty, loose body retrieval, and limited meniscal repair. A new methodology for the measurement of plasma bupivacaine using the gas chromatograph mass spectrometer is described. Monitoring specific molecular mass fragments allows the measurement of picogram per milliliter levels of bupivacaine. The highest peak plasma concentration occurred 20 minutes after instillation of 30 ml of 0.5% bupivacaine. The 625 +/- 225 ng/ml level was well below the 2,500 to 4,000 ng/ml reported to elicit early subjective CNS symptoms of bupivacaine toxicity. Thus, a single dose intraarticular instillation of 30 ml 0.5% or 0.25% bupivacaine is convenient, efficacious, and pharmacologically safe for routine clinical arthroscopy.

    Background and purpose Several randomized controlled trials have not shown any added benefit of arthroscopy over placebo surgery or physiotherapy in middle-aged patients with knee symptoms without trauma. We studied the characteristics of the knee arthroscopies performed in southern Sweden. Patients and methods From the orthopedic surgical records from 2007–2009 in the Skåne region of Sweden (with a population of 1.2 million), we retrieved ICD-10 diagnostic codes and selected all 4,096 arthroscopies that were diagnosed peroperatively with code M23.2 (derangement of meniscus due to old tear or injury) or code M17 (knee osteoarthritis). We extracted information on cartilage and meniscus status at arthroscopy, and we also randomly sampled 502 of these patients from the regional archive of radiology and analyzed the preoperative prevalence of radiographic or magnetic resonance imaging (MRI)-defined osteoarthritis. Results 2,165 (53%) of the 4,096 arthroscopies had the diagnostic code M23.2 or M17. In this subgroup, 1,375 cases (64%) had typical findings consistent with degenerative meniscal tear (i.e. that correspond to a degenerative meniscal tear in at least a third of all arthroscopies). Of the randomly sampled patients, the preoperative prevalence of radiological knee osteoarthritis was 46%. Interpretation There is a discrepancy between evidence-based medicine treatment guidelines and clinical practice regarding the amount of knee arthroscopies performed in patients with symptoms of degenerative knee disease.

    Full Text Available Abstract Background Arthroscopy is often used to treat patients with chronic patellofemoral pain syndrome (PFPS. As there is a lack of evidence, we conducted a randomized controlled trial to study the efficacy of arthroscopy in patients with chronic PFPS. Methods A total of 56 patients with chronic PFPS were randomized into two treatment groups: an arthroscopy group (N = 28, treated with knee arthroscopy and an 8-week home exercise program, and a control group (N = 28, treated with the 8-week home exercise program only. The arthroscopy included finding-specific surgical procedures according to current recommendations. The primary outcome was the Kujala score on patellofemoral pain and function at 9 months following randomization. Secondary outcomes were visual analog scales (VASs to assess activity-related symptoms. We also estimated the direct healthcare costs. Results Both groups showed marked improvement during the follow-up. The mean improvement in the Kujala score was 12.9 (95% confidence interval (CI 8.2–17.6 in the arthroscopy group and 11.4 (95% CI 6.9–15.8 in the control group. However, there was no difference between the groups in mean improvement in the Kujala score (group difference 1.1 (95% CI -7.4 - 5.2 or in any of the VAS scores. Total direct healthcare costs in the arthroscopy group were estimated to exceed on average those of the control group by €901 per patient (p Conclusion In this controlled trial involving patients with chronic PFPS, the outcome when arthroscopy was used in addition to a home exercise program was no better than when the home exercise program was used alone.

    Elbow arthroscopy is a useful diagnostic and therapeutic tool for various conditions. Conventional arthroscopy with the patient in the prone or lateral position where the screen is placed on the opposite side makes it difficult to interpret the image, results in visual paradox, and is associated with difficult triangulation. We present a modified setup for the operating room to help eliminate these problems and improve triangulation.

    Complications after arthroscopic surgery of the knee joint are infrequent. Quadriceps tendon ruptures after knee arthroscopy are rarities. Only two cases have been published in the medical literature. This article presents a case of a quadriceps tendon rupture that occurred in a 19-year-old patient 5 weeks after lateral release of the retinaculum by arthroscopy. The late occurrence differentiates this case from the other previously published cases.

    The purpose of this article is to perform a systematic review and meta-analysis of elbow arthroscopy literature to answer the following questions: "Across the world, what demographic of patients are undergoing elbow arthroscopy, what are the most common indications for elbow arthroscopy, and how good is the evidence?" The authors hypothesized that patients who undergo elbow arthroscopy will be chiefly age evidence regarding elbow arthroscopy will be poor. Also, no significant differences will exist in elbow arthroscopy publications, subjects, outcomes, and techniques based on continent/country of publication. A systematic review was registered with the International Prospective Register of Ongoing Systematic Reviews (PROSPERO) and performed with Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines using 3 publicly available databases. Therapeutic clinical outcome investigations reporting arthroscopic elbow outcomes with levels of evidence I-IV were eligible for inclusion. All study, subject, and surgical technique demographics were analyzed and compared between continents and countries. Statistics were calculated using 1-way analysis of variance (ANOVA) to compare between continents and Pearson's correlation coefficients to evaluate changes over time. In total, 112 studies were included (3093 subjects; 3168 elbows; 64% male; mean 34.9 ± 14.68 years. Mean 33.4 ± 26.02 months follow-up. Most studies were level IV evidence (94.6%) and had a low Modified Coleman Methodology Score (MCMS) (mean 28.1 ± 8.06). From 1985 through 2013, the number of publications significantly increased with time (P = .004) in all continents. The 3 most common indications for elbow arthroscopy were osteochondritis dissecans (OCD), lateral epicondylitis, and release and débridement. The number of reported cases for the 3 most common indications significantly increased over time but did not differ between regions (P > .05 in all cases). Thirty-two studies

    2015-01-01

    Full Text Available A 41-year-old man with an unremarkable medical history presented with a painful knee after a sports injury. He was diagnosed with a medial meniscal tear. Symptoms did not abate after 6 months of physical therapy, and he underwent arthroscopic partial medial meniscectomy. A week after beginning physical therapy he experienced a knee effusion, decreased ROM, and inability to flex his quadriceps. His knee was aspirated. Blood tests were ordered and his complete blood count, liver functions tests, and INR/PTT were normal. The patient had recurrent effusions requiring three additional joint aspirations. Ten weeks after the initial surgery, the patient underwent a second arthroscopy, during which a hematoma was removed and a synovectomy performed. The patient continued bleeding from the incisions after portals were sutured, and he was admitted to the hospital. A hematologist was consulted and comprehensive platelet aggregation testing revealed previously undiagnosed Glanzmann’s thrombasthenia. The patient began treatment with platelet infusions and desmopressin and progressed to a full recovery. Clinical suspicion for surgical patients with unusual repetitive postoperative bleeding should include previously undetected rare bleeding disorders even in adults.

    2001-01-01

    Objective: To evaluate the therapeutic effects of retrograde interlocking intramedullary nailing under arthroscopy on supracondylar femoral fractures.   Methods: From June 1999 to December 2000, 17 patients with supracondylar femoral fracture were treated with arthroscopically assisted implantation of retrograde interlocking intramedullary nail and close reduction.   Results: More than 6-month follow-up study after operation in 11 patients revealed that the average healing time was 3 months. Average range of the knee motion for all the patients was more than 90 degrees. There was no implant breakage and infection.   Conclusions: This new method, combining the advantage of arthroscope and retrograde interlocking intramedullary nail, can provide a stable and reliable fixation, and meanwhile is less invasive to the soft tissue and knee, less operative time and blood loss, minimal disruption of the blood supply in fracture site. It is conducive to the fracture healing and the functional recovery of the knee joint and worthwhile to be recommended.

  9. Diagnostic Efficiency of MR Imaging of the Knee. Relationship to time Interval between MR and Arthroscopy

    International Nuclear Information System (INIS)

    To evaluate the efficiency of magnetic resonance (MR) in the diagnosis of knee lesions and how the results are influenced by the time interval between MR and arthroscopy. 248 knees studied by MR were retrospectively analyzed, as well as those which also underwent arthroscopy. Arthroscopy was considered to be the gold standard, MR diagnostic capacity was evaluated for both meniscal and cruciate ligament lesions. Sensitivity, specificity and Kappa index were calculated for the set of all knees included in the study (248), for those in which the time between MR and arthroscopy was less than or equal to three months (134) and for those in which the time between both procedures was less than or equal to one month. Sensitivity, specificity and Kappa index of the MR had global values of 96.5%, 70% and 71%, respectively. When the interval between MR and arthroscopy was less than or equal to three months, sensitivity, specificity and Kappa index were 95.5%, 75% and 72%, respectively. When it was less than or equal to one month, sensitivity was 100%, specificity was 87.5% and Kappa index was 91%. MR is an excellent tool for the diagnosis of knee lesions. Higher MR values of sensitivity, specificity and Kappa index are obtained when the time interval between both procedures is kept to a minimum. (Author) 11 refs

    Purpose: A prospective study was undertaken to determine the accuracy of ultrasound compared with arthroscopy in the evaluation of the symptomatic supraspinatus tendon, and to identify whether ultrasound diagnosis was helpful in pre-operative planning. Methods: A total of 276 consecutive patients with shoulder impingement symptoms underwent ultrasound examination of the supraspinatus tendon. Of these patients, 41 proceeded to open or arthroscopic surgical procedure on clinical grounds, and in this group direct comparison with ultrasound findings was made. Results: There was full correlation between ultrasound and arthroscopy in the diagnosis of a normal supraspinatus tendon, full-thickness tear, tendinopathy and tendon rupture. There was some discrepancy between the two techniques. Two patients with partial thickness tear on ultrasound had a full thickness tear at arthroscopy. Ultrasound was able to identify intra-substance partial thickness tears in three patients with supraspinatus tendon said to be normal at arthroscopy. Ultrasound helped plan the surgical approach and operative time needed in cases of supraspinatus tendon rupture and full thickness tear. Conclusion: In this study ultrasound was effective in the evaluation of the symptomatic supraspinatus tendon, and was also able to diagnose intra-tendinous lesions not visible at arthroscopy.

    Because of suspected rupture of the anterior cruciate ligament sixteen acute traumatised patients were investigated by MR and arthroscopy. The MR diagnosis of a lesion of the anterior cruciate ligament proved to be correct by arthroscopy in fifteen of sixteen cases. Diagnostic criteria for lesions of the anterior cruciate ligament were: increased signal intensity in T[sub 1]- and T[sub 2] weighted images, increased volume and discontinuity of ligamentous structures. Additional MR findings of meniscal tears were correct in three of four cases laterally and in four of four cases medially. Femoral cartilage lesions were correctly identified by MR in three cases. MR normal findings proved to be correct by arthroscopy in another five cases. (orig.).

    The objective of this study was to develop and validate a computer-based module for wrist arthroscopy to which a group of experts could consent. The need for such a module was assessed with members of the European Wrist Arthroscopy Society (EWAS). The computer-based module was developed through several rounds of consulting experts on the content. The module's learning enhancement was tested in a randomized controlled trial with 28 medical students who were assigned to the computer-based module group or lecture group. The design process led to a useful tool, which is supported by a panel of experts. Although the computer based module did not enhance learning, the participants did find the module more pleasant to use. Developing learning tools such as this computer-based module can improve the teaching of wrist arthroscopy skills.

    We describe the MR appearance of fibrous scars in the infrapatellar fat pad after arthroscopy. The subjects were 96 patients who underwent arthroscope-assisted anterior cruciate ligament (ACL) reconstruction and were examined by oblique sagittal MR imaging at different follow-up intervals. Two observers evaluated the characteristics of the fibrous scars in the infrapatellar fat pad. All fibrous scars with low signal intensity were accentuated at the portal and coursed horizontally through the infrapatellar fat pad. The fibrous scar within the fat pad occurred and peaked within 6 months after arthroscopy. It then subsided gradually and had disappeared by one year later in nearly half of the patients. Identifying MR imaging characteristics of fibrous scars in the fat pad after arthroscopy may be clinically helpful to differentiate these scars from other abnormalities that involve the infrapatellar fat pad.

    Full Text Available INTRODUCTION: The anterior cruciate ligament (ACL is one of the most frequently injured ligaments in the human body. 1 The Anterior Cruciate ligament (ACL is the primary stabilizer of the knee and prevents the knee against anterior translation. 2 It is also important in counteracting rotational and valgus stress. 1 The middle third of the patellar tendon autograft for ACL reconstruction can be readily procured and firmly fixed. 3 It can tolerate the loads produced by an intensive rehabilitation programme. 3 Fixation of bone plugs using interference screws provides sufficient stability to meet the demand of a vigorous postoperative protocol. 3 It remains the gold standard for ACL reconstruction. 3 This study is to assess the functional outcome of arthroscopy assisted anterior cruciate ligament reconstruction using bone patellar tendon bone autograft. METHODS: This study was conducted in Kempegowda Institute of Medical Sciences Hospital from November 2012 to April 2014. During this period 20 cases of adult patients with ACL deficient patients were selected according to the inclusion criteria. Study aims to assess the functional outcome of arthroscopy assisted anterior cruciate ligament reconstruction using bone - patellar tendon - bone autograft in terms of range of motion, postoperative knee stability, graft site morbidity and subjective knee functions. RESULTS: Results of our study showed that arthroscopy assisted anterior cruciate ligament reconstruction with bone - patellar tendon - bone autograft could effectively improve knee stability and functions after surgery without any complication. CONCLUSION : Arthroscopy assisted anterior cruciate l igament reconstruction with bone - patellar tendon - bone autograft is an excellent treatment option for anterior cruciate ligament deficient knees. It provides a stable knee and reduces postoperative morbidity and enables early rehabilitation. The functional outcome of arthroscopy assisted anterior

    Humans are notably poor at predicting event outcomes. In "Correlation of Synovial Fluid Biomarkers With Cartilage Pathology and Associated Outcomes in Knee Arthroscopy," Cuellar, Cuellar, Kirsch, and Strauss show that some synovial fluid biomarkers (20 were sampled for the investigation) may predict operative findings at the time of arthroscopy and patient-reported outcome measures at follow-up. Further research will clarify the role of synovial biomarkers in knee pathology and, hopefully, narrow the choices to one or two pertinent markers that can be used to improve our ability to predict outcomes from arthroscopic knee surgery.

    2016-07-01

    Arthroscopy of the foot and ankle is a common orthopedic procedure with low complication rates. Arterial injuries from these procedures are an even more rare subset of the complications. Hemophilia A is a genetic disorder of aberrant coagulation, which leads to increased risk of bleeding even after minor trauma. We present the second case of anterior tibial artery pseudoaneurysm formation secondary to ankle arthroscopy in a hemophiliac patient and suggest that these individuals are at higher risk for developing complications associated with arterial injury. Furthermore, potential risk factors include port placement, anatomic variation of the vessels, and nature of the arthroscopic procedure. We recommend steps to prevent complications in hemophiliac patients. PMID:27174350

    1984-02-01

    2 patients with a history of reciprocal temporomandibular joint (TMJ) clicking were visually examined with arthroscopy of their right side TMJs. Clinical and radiographic examination revealed no signs of arthrosis deformans. One patient with significantly reduced opening ability combined with occasional disappearance of TMJ clicks showed advanced arthrotic changes of cartilage which were not visible radiographically. The other patient with unimpaired function also had a severe arthrotic lesion in the clicking joint. In neither case did the disk appear to be displaced. It is concluded that arthroscopy yields additional information for TMJ diagnosis which cannot be achieved by clinical and radiographic examination alone.

    1999-07-01

    The aim of this study was to assess the accuracy of MR in the diagnosis of synovialisation of the anterior cruciate ligament (ACL) compared with arthroscopy. One hundred and forty-nine patients were examined with MR imaging and arthroscopy of the knee. The MR sign used to consider a synovialised ACL consisted of hypointense fibrillar tracts, disrupted and wavily, in its expected course. Sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV), comparison of proportions (McNemar test) and Kappa values for agreement between MR imaging and arthroscopy were calculated. Of the 133 (89.3 %) ligaments without synovialisation at arthroscopy, 130 accorded with the MR results. Of the 16 (10.7 %) synovialised ligaments, 13 accorded with the MR results. Three false-positive and three false-negative MR diagnoses were identified. The agreement between both techniques was excellent (Kappa = 0.79; p = 0.000), without differences (McNemar test; p = 1). Sensitivity was 0.81, specificity 0.98, PPV 0.98 and NPV 0.81. Magnetic resonance imaging is highly reliability for synovialisation diagnosis. The imaging sign used to diagnose synovialised ACL (hypointense comma-like tracts in its expected course) is reliable. As this reparative process can simulate an intact ligament, knowledge of this sign is important in diagnosing synovialisation of ACL tears so as not to confuse it with normal ACL. (orig.)

There was made in all cases debridation with shaver, in 12 cases microabrasive chondroplasty and in 7 cases ligamentoplasty of the anterior talofibular ligament and/or deltoid ligament. In 76% there was, at least an associated, „hiden”, lesion, wich need also arthroscopic treatment. We have one complication (4,3% represented by a superficial chondral lesion, wich was treated by microabrasive chondroplasty. There were any neurological, vascular or other complications. The results show us that ankle arthroscopy remain a certain, mini-invazive method to diagnose and for the treatment of the ankle lesions. Arthroscopic ligamentoplasty of the ankle is still in confirmation. Arthrocopy is the main procedure for treating the impingement syndrom of the ankle and osteochondral lesion – injury that are frecventely associated with chronic ankle instability.

    Arthroscopic ultrasound imaging enables quantitative evaluation of articular cartilage. However, the potential of this technique for evaluation of subchondral bone has not been investigated in vivo. In this study, we address this issue in clinical arthroscopy of the human knee (n = 11) by determining quantitative ultrasound (9 MHz) reflection and backscattering parameters for cartilage and subchondral bone. Furthermore, in each knee, seven anatomical sites were graded using the International Cartilage Repair Society (ICRS) system based on (i) conventional arthroscopy and (ii) ultrasound images acquired in arthroscopy with a miniature transducer. Ultrasound enabled visualization of articular cartilage and subchondral bone. ICRS grades based on ultrasound images were higher (p < 0.05) than those based on conventional arthroscopy. The higher ultrasound-based ICRS grades were expected as ultrasound reveals additional information on, for example, the relative depth of the lesion. In line with previous literature, ultrasound reflection and scattering in cartilage varied significantly (p < 0.05) along the ICRS scale. However, no significant correlation between ultrasound parameters and structure or density of subchondral bone could be demonstrated. To conclude, arthroscopic ultrasound imaging had a significant effect on clinical grading of cartilage, and it was found to provide quantitative information on cartilage. The lack of correlation between the ultrasound parameters and bone properties may be related to lesser bone change or excessive attenuation in overlying cartilage and insufficient power of the applied miniature transducer.

  6. Prospective, double-blind comparison of shoulder MR imaging, US, arthrography, and arthroscopy

    International Nuclear Information System (INIS)

    To determine the efficacy of diagnostic imaging modalities in the evaluation of shoulder pain, magnetic resonance (MR) imaging, ultrasonography (US) and arthrography were prospectively compared in a double-blind experimental protocol. Thirty consecutive patients were studied by these modalities, which received separate, blinded interpretations. The images and interpretations were sealed in an envelope and blinded from the arthroscopist for initial arthroscopy, but second-look arthroscopy, and in some cases open surgery, was performed after the envelopes were unsealed. To avoid selection bias, negative MR and/or US examinations never affected confirmation by arthrography and/or arthroscopy, so negatives and positives were equivalently tested. To date, MR imaging and US are equally sensitive in the detection of rotator cuff tears, but the combination is more sensitive. Both MR imaging and US demonstrated tears not diagnosed by means of arthrography, and MR imaging distinguished hemorrhagic muscle tears from rotator cuff tears, which arthrography and arthroscopy did not. Both MR imaging and US showed characteristic appearances of biceps tendonitis, but neither demonstrated adhesive capsulitis. The authors conclude that all three imaging modalities have a role in shoulder diagnosis

    Full Text Available Hip arthroscopy has continued to expand its horizons in treating many conditions other than femoroacetabular impingement (FAI. However, the results of hip arthroscopy are known to be poor if the degree of articular cartilage damage is significant. We wanted to assess, whether the procedure might have a role in the management of young and active patients with advanced osteoarthritis (OA and whether it should be offered as a treatment modality. 77 consecutive patients with Tönnis grade 2 and 3 osteoarthritis of the hip who had undergone hip arthroscopy were included in the study. Patients' medical notes, plain radiographs and outcome scores (modified Harris hip score (mHHS, non-arthritic hip score (NAHS preoperatively and postoperatively at six weeks, six months, one year and annually thereafter, were analysed. 77 patients consisted of 63 men and 14 women with mean follow-up of 2.8 years (2.2 to 4.2 and mean age at surgery of 43 years (19 to 64. The mean preoperative mHHS and NAHS scores were 58 (28 to 87 and 64 (27 to 93 respectively. The mean improvements in both the mHHS and NAHS scores were significant (p = 0.003 and p = 0.0001 for mHHS at one and two years, p = 0.002 and p = 0.0003 for NAHS at one and two years, respectively. There were 34 patients (44% who required a total hip replacement at mean of 18 months (6 to 48 after hip arthroscopy. We conclude that hip arthroscopy improves outcome scores in 56% of patients with severe OA of the hip (Tönnis grade 2 and 3 for at least two years after surgery. We thus consider the procedure to be a reasonable option for patients with hip OA, although success of the procedure will be less than if undertaken for certain other conditions.

    Several commercially available cartilage repair techniques use a natural or synthetic matrix to aid cartilage regeneration (e.g., autologous matrix-induced chondrogenesis or matrix-induced cartilage implantation). However, the use of matrix-aided techniques during conventional knee joint arthroscopy under continuous irrigation is challenging. Insertion and fixation of the matrix can be complicated by the presence of fluid and the confined patellofemoral joint space with limited access to the lesion. To overcome these issues, we developed a novel arthroscopic approach for matrix-aided cartilage repair of patellar lesions. This technical note describes the use of dry arthroscopy assisted by a minimally invasive retraction system. An autologous matrix-induced chondrogenesis procedure is used to illustrate this novel approach.

    Hip arthroscopy in patients with osteoarthritis has been shown to have suboptimal outcomes. Elevated cytokine concentrations in hip synovial fluid have previously been shown to be associated with cartilage pathology. The purpose of this study was to determine whether a relationship exists between hip synovial fluid cytokine concentration and clinical outcomes at a minimum of 2 years following hip arthroscopy. Seventeen patients without radiographic evidence of osteoarthritis had synovial fluid aspirated at time of portal establishment during hip arthroscopy. Analytes included fibronectin-aggrecan complex as well as a multiplex cytokine array. Patients completed the modified Harris Hip Score, Western Ontario and McMaster Universities Arthritis Index and the International Hip Outcomes Tool pre-operatively and at a minimum of 2 years following surgery. Pre and post-operative scores were compared with a paired t-test, and the association between cytokine values and clinical outcome scores was performed with Pearson's correlation coefficient with an alpha value of 0.05 set as significant. Sixteen of seventeen patients completed 2-year follow-up questionnaires (94%). There was a significant increase in pre-operative to post-operative score for each clinical outcome measure. No statistically significant correlation was seen between any of the intra-operative cytokine values and either the 2-year follow-up scores or the change from pre-operative to final follow-up outcome values. No statistically significant associations were seen between hip synovial fluid cytokine concentrations and 2-year follow-up clinical outcome assessment scores for those undergoing hip arthroscopy.

    Fractures of the distal radius, which currently are treated with palmar locking plates, are often accompanied by carpal lesions. Tears of the scapholunate interosseus ligament (SL) can affect the outcome. Between January 2007 and May 2008, 28 patients with distal intraarticular fractures of the radius were included in a prospective study. Preoperative CT-arthrography was performed. SL tears were found in 11 patients, with 10 partial and one complete rupture observed. A tear of the triangular fibrocartilage complex (TFCC) was detected in 16 patients. Every patient was operated with a palmar locking plate through a palmar approach between the flexor carpi radialis tendon and the radial artery. Then, a palmar wrist arthroscopy using a palmar portal was performed. Eleven SL tears with 9 partial and two total ruptures were diagnosed by arthroscopy. Ten lesions were associated with a C1-fracture with a fracture line projected onto the scapholunate interval. The TFCC was appraisable by palmar wrist arthroscopy only in 4 patients. Three of the SL tears detected by CT-arthrography could not be confirmed by palmar wrist arthroscopy. One complete rupture and one partial lesion confirmed by palmar wrist arthroscopy were found by CT-arthrography to be intact. Palmar wrist arthroscopy affords certainty when assessing the SL ligament. In this study, an assessment of ulnocarpal structures was not possible. For assessment of the ulnocarpal structures, CT-arthrography was superior to palmar wrist arthroscopy. However, the latter is an alternative during emergency treatment or when CT-arthrography is not available. PMID:19790024

    To determine the diagnostic accuracy of CT arthrography and virtual arthroscopy in the diagnosis of anterior cruciate ligament and meniscus pathology. Thirty-eight consecutive patients sho underwent CT arthrography and arthroscopy of the knee were included in this study. The ages of the patients ranged from 19 to 52 years and all of the patients were male. Sagittal, coronal, transverse and oblique coronal multiplanar reconstruction images were reformatted from CT arthrography. Virtual arthroscopy was performed from 6 standard views using a volume rendering technique. Three radiologists analyzed the MPR images and two orthopedic surgeons analyzed the virtual arthroscopic images. The sensitivity and specificity of CT arthrography for the diagnosis of anterior cruciate ligament abnormalities were 87.5%-100% and 93.3%-96.7%, respectively and those for meniscus abnormalities were 91.7%-100% and 98.1%, respectively. The sensitivity and specificity of virtual arthroscopy for the diagnosis of anterior cruciate ligament abnormalities were 87.5% and 83.3%-90%, respectively, and those for meniscus abnormalities were 83.3%-87.5% and 96.1-98.1%, respectively. CT arthrography and virtual arthroscopy showed good diagnostic accuracy for anterior cruciate ligament and meniscal abnormalities.

  1. The role of arthroscopy in the management of low-velocity gunshot wounds of the knee joint.

    Eight patients with low-velocity civilian gunshot wounds of the knee were examined and evaluated by arthroscopy. Three of these patients were also treated by surgical arthroscopy and underwent limited arthrotomy for bullet removal. In two patients small arthrotomy incisions were made following arthroscopic exploration for removal of bullets. Two patients underwent diagnostic arthroscopy. One underwent internal fixation for a chondral fracture of the femoral condyle. The majority of patients sustained intra-articular damage and retained foreign materials (denim flecks and metallic shards) and osteochondral fragments. There were no postoperative infections after a minimum follow-up period of one year. Arthroscopy is highly effective in the diagnosis and surgical management of low-velocity gunshot wounds of the knee both alone and in combination with limited arthrotomy depending on the severity of the condylar damage. The length of the hospital stay is reduced (length of stay exceeded 3-4 days only as a result of intravenous antibiotic coverage). Physical therapy requirements are minimal. Active mobility and a full range of motion are regained more rapidly with arthroscopy than with surgical exposure of multiple exploratory incisions or conventional standard arthrotomy. PMID:6705381

  2. Algorithm for establishing the indication for knee arthroscopy in children: a comparison of adolescent and preadolescent children.

    The aim of this study was to select children with pathological lesions of the intra-articular structures from children with identical complaints but with no pathological intra-articular changes. The younger the child, the more difficult it is to make the diagnosis, and the expected distribution of pathology changes increasingly. This is particularly stressed in children aged younger than 13 years. Synovial inflammatory alterations are more frequent, and osteochondral and chondral fractures appear to be more problematic than meniscal and cruciate ligament lesions. Before establishing the indication for knee arthroscopy it is mandatory to implement the algorithm of diagnostic and conservative therapeutic procedures. The indication for knee arthroscopy is considered in cases when complaints persist after conservative treatment, a lesion of intra-articular segments is suspected, and the pathological condition is deemed arthroscopically treatable. Arthroscopy before conservative treatment is justified only in acute cases.

    Purpose To provide an efficient learning process, feedback on performance is crucial. In skills laboratories, it is possible to measure the skills and progression of skills of the trainees objectively. This requires metrics that represent the learning curve of the trainee, which were investigated for wrist arthroscopy. The research questions were: What are the forces used by novices during wrist arthroscopy?What aspects of these navigation forces are discriminative for the wrist arthroscopy skills level?Methods A cadaver wrist was mounted in a custom-made distraction device mounted in front of a force platform (ForceTrap). Eleven novices were invited to perform two tasks on the wrist: Insertion of the scope through the 3-4 portal and the hook through the 6R portal, and visualization of the hook in the center of the imageNavigation through the wrist from radial to ulnar with probing and visualization of five predefined landmarksThe second task was repeated 10 times. The absolute force (F abs) and the direction of force were measured. The angle α is defined in the vertical plane, and the angle β in the horizontal plane. Results The median F abs used by novices remained below the force threshold as defined from the expert data (7.3 N). However, the direction of the applied forces by novices in both planes was not consistent with expert data and showed a wider range. Also, there was no improvement after more trials. Conclusion Our study suggests by the absence of a learning curve for the novices and a significant difference between novices and experts that novices can benefit from feedback on the magnitude and direction of forces to improve their performance.

    Background There are many different materials used for ligament reconstruction. Currently, autograft, allograft, and artificial ligaments are used in the reconstruction. The objective of this study was to explore the clinical result of cruciate ligament reconstruction under arthroscopy.Methods Eighty-one cases were reconstructed with the LARS ligament under arthroscopy, including 43 cases of anterior cruciate ligament (ACL) injury, 20 cases of posterior cruciate ligament (PCL) injury, and 18 cases of ACL combined with PCL injuries of the knee. The follow up period was 10 to 49 months. The International Knee Documentation Committee (IKDC) and Lysholm knee score scales were used for functional evaluation. We examined the anterior and posterior stability of the knee with KT-1000.Results According to the Lysholm knee function score scale, the average preoperative score of (44.6±1.4) increased to a postoperative score of (82.8±2.5) in the ACL group and from (46.6±2.3) to (80.8±2.0) in the PCL group. In the ACL combined with PCL injury group, the preoperative score increased from (45.2±1.2) to (85.5±2.3). According to IKDC score standards, in ACL group we evaluated 19 cases as C and 24 cases as D, preoperatively, and postoperatively 27 cases as A, 14 cases as B and two cases as C. In the preoperative PCL group, we had 11 cases defined as C and nine cases as D that resolved to 12 cases as A, seven as B and one case of C in postoperative evaluation. In the ACL combined with PCL injury group we defined four cases as C and 14 as D during preoperative scoring. These patients had postoperative grades of six cases as A, 10 as B, and two cases as C. All of the results have statistical significance. Conclusions ACL, PCL, or combined ACL and PCL reconstruction using the LARS ligament under arthroscopy is a minimally invasive, safe and effective method to treat cruciate ligament injuries of the knee. Clinical results are satisfactory in the short term.

    Objectives: Cam-type femoroacetabular impingement (FAI) causes a shearing and delamination injury to the acetabular articular cartilage due to a mismatch between the size of the femoral head and the acetabulum. This mechanism is thought to lead to early osteoarthritis in this population. Cam decompression has been advocated to eliminate impingement, with the ultimate goal of halting the progression of articular cartilage delamination. Although outcomes following this procedure in the young adult population have been favorable at short and medium term follow up, it is not known whether the articular cartilage itself is protected from further injury by changing the biomechanics of the joint with decompression of the cam morphology. The purpose of this study is to compare the pre- and post-operative integrity of the acetabular articular cartilage using T2 mapping to determine if hip arthroscopy is protective of the articular cartilage at short- to medium term follow up. Methods: Males between 18 and 35 years of age who had pre-operative T2 mapping MRIs, underwent hip arthroscopy for cam or mixed-type FAI with an alpha angle greater than 50°, and had at least 2 year follow-up were identified. Post-operative MRIs were performed and T2 relaxation times in the transition zone and weight bearing articular cartilage in the anterosuperior acetabulum at deep and superficial chondral layers were recorded at nine points on three sagittal sequences on pre and post-operative MRIs. A paired t-test was used to compare T2 relaxation values between pre-operative and post-operative scans. Results: Eleven hips were evaluated. Mean age was 26.3 years (range 21 - 35). Mean follow up time to post-operative T2 mapping MRI was 2.6 years (range 2.4 - 2.7). The change in T2 relaxation time was not significantly different between pre- and post-operative MRI scans for any of the nine regions in the deep zone of the acetabular cartilage (p=0.065 - 0.969) or the superficial zone of the

    International Nuclear Information System (INIS)

    A prospective study of patients with surgical treatment of the knee through arthroscopy was carried out at the Rheumatology Service, belonging to 'Saturnino Lora' Teaching Clinical Surgical Provincial Hospital from Santiago de Cuba during the years 2000-2009; a decade in which 663 knees were surgically treated and, 208 due to a synovial plica. This last one turned out to be the most frequent disease, with predominance in the female sex and the ages from 16 to 25 years. There was a marked clinicoarthroscopic correspondence. Preoperative diagnosis consisted of lesion of the internal meniscus, chondromalacia patellae and synovitis, reason why they should be kept in mind as differential diagnosis in this syndrome. The way of healing the surgical section of the synovial plica is the cause of symptomatic relapse and surgical reintervention, as it happened in the patients of the case material 54,0 %, mainly attributable to fibrosis in the wound area.(author)

    5Objective:To evaluate the values of spiral CT arthrography with multiplanar reconstruction and virtual arthroscopy technique in diagnosis of internal derangements of the knee. Methods:Ten bovine knees were used for experiment. The menisci, anterior and posterior cruciate ligaments and cartilage of these 10 bovine knees were injured with a hook. Each of the joints was injected with 100 mi air, then soon scanned with a PQ6000 spiral computed tomography scanner. The data obtained was input into the work station, and multiplanar reconstruction technique was used to illustrate lesions in the knees. The results of CT diagnosis were compared to those found by gross inspection of the specimens. Clinically, 10 knees of 9 patients diagnosed as internal derangement were evaluated with the same method after 50-70 ml air was injected into each of the joints. Nine months later, the data of 2 patients were used for CT endoscopy reconstruction. The results were compared with intraoperative findings. Results:Experimentally,the sensitivity and specificity were 88.9% and 93.9% by detection of meniscal abnormalities, 85.7% and 100% by detection of cruciate ligament lesions, and 72.7% and 100% by detection of cartilage damage, respectively. Clinically, the sensitivity and specificity were 90. 0% and 95.0% by detection of meulscal lesion. As to ligament, the figures were 85.7% and 100% respectively. Images of virtual arthroscopy simulated the images of real arthroscopy. Conclnsious:Spiral CT arthrography of multiplanar reconstruction technique offers fime images of internal structures of the knee, with clear border and internal structure. It is an accurate method for detecting meulscal, cruciate and collateral ligament and cartilaginous lesions that cause internal derangement of the knee.Virtual arthroscopy technique is a hopeful method for detecting reasons of derangement of the knee.

    Objective: To evaluate operative effects of a new method to reconstruct anterior crucial ligament (ACL) and posterior crucial ligament (PCL) simultaneously by using patellar tendon under arthroscopy.Methods: From November 1999 to November 2003,the injured ACL and PCL of 11 patients were fixated with compressed screws and reconstructed under arthroscopy with the bone-patellar tendon-bone treated with deep hypothermia and T radiation. At the same time, 2 patients were treated with medial collateral ligament (MCL)reconstruction, 3 with lateral collateral ligament (LCL)reconstruction, 1 with meniscus suture and 4 with whole or partial resection.Results: All patients were followed up for 12-26months (average 16.5 months ). The Lysholm score method was employed to evaluate the knee function. The average preoperative score was 45.3 and the postoperative score was 86.4. Anterior drawer test (ADT) was positive in 11 knees preoperatively and feeble positive in one knee postoperatively. Lachman test was positive in 11 knees preoperatively and in one postoperatively, and feebly positive in two postoperatively. Posterior drawer test was positive in 11 knees preoperatively and feebly positive in 2postoperatively. There were 2 knees with tolerable pain and 2 with knee flexion of 5°-20°.Conclusions: As for simultaneous reconstruction of ACL and PCL under arthroscopy, ailogeneic bone-patellar tendon-bone can not only avoid injury and complication caused by autografting, but also help rehabilitation of the knee function.

    The purpose of this paper is to retrospectively review 234 consecutive cases of scaphoid fractures and nonunions treated using arthroscopy with the dorsal percutaneous implantation of a headless compression screw for healing and complications. Solid union of fracture is determined by CT scan. We identified 126 acute injuries, including 65 proximal pole fractures; 67 grossly displaced fractures; 12 trans-scaphoid perilunate dislocations including four trans-scaphoid trans-capitate fractures; and ten combined scaphoid and distal radius fractures. 108 scaphoid nonunions were identified. 98 were correctly aligned and ten had a humpback deformity which was correctable using arthroscopic assisted reduction techniques at the time of surgery. 82 presented with a fracture gap 2mm or greater requiring percutaneous bone grafting. 12 cases of avascular necrosis (AVN) were identified by MRI. 20 nonunions had surgery performed at other institutions. The mean time to surgery for the nonunions was 20 months. 99% union rate of acute scaphoid fractures was obtained by 12 weeks, as determined by CT scan. Two complications were identified (3%). One case of delayed healing was identified. this delayed union was treated with percutaneous bone grafting and continued on to heal uneventfully. The other complication was a case of volar trans-scaphoid peri-lunate dislocation. While the fracture healed, the patient developed a traumatic dislocation requiring a capitate-lunate arthrodesis. Treatment of scaphoid nonunions resulted in ten cases of delayed healing, which were treated with repeat percutaneous bone grafting. This represented a 9% complication rate. of the ten cases of delayed unions that were re-bone grafted, four failed to heal by nine months. This resulted in a 96% union rate of our nonunion group by nine months. when acute fracture healing was compared to nonunions the average healing of acute fractures as determined by CT scanning measuring trabecular bridging was 12 weeks

    髋关节镜技术近20年飞速发展,在髋关节损伤诊断治疗领域的作用愈加显著.以往通过X线、CT或MRI等检查无法确定的髋关节病损也可通过髋关节镜检查得到较为明确的诊断,该技术逐渐成为髋关节疾病诊断的金标准.目前,髋关节镜检查入路主要有外侧入路、前侧入路、后外侧入路,应用范围主要包括孟唇撕裂、股骨髋臼撞击症、圆韧带损伤、软骨损伤、滑膜疾病、关节内感染、关节内游离体等.髋关节镜技术是一项综合性技术,其优点得以良好体现须手术者熟悉掌握该技术的适应证、禁忌证以及手术操作方法,必须在术前进行细致的物理检查及影像学检查,在术后进行合理有效的康复功能训练.%The hip arthroscopy develops quickly in the past 20 years. Its use in the diagnosis and treatment of the hip injury get more notably. Many of pathologic conditions previously unrecognized through X-ray,CT or MRI have been diagnosed correctly under hip arthroscopy. The technology has become gradually a golden standard to confirm the hip discords. In the present, the examining path of the hip arthroscopy contains mainly the outside path, the anterior path, the outside-posterior path. The application range of the hip arthroscopy includes the management of labral tears, the femoroacetabular impingement, the ligamentum tear injuries,the chondral lesions,the synovical abnormalities,the intra-articular infection,the loose bodies in the joint etc. The hip arthroscopy is a comprehensive technology. Its superiority can be reflect well if the doctors are familiar with the indication,the contraindication and the operation procedure. And also the thorough physical examination and imaging examination should be made before operation,as well as reasonable and effective postoperative function training should be conducted.

    Objectives: Until now, arthroscopic surgery has been the gold standard for the diagnosis of intra-articular pathology. When a patient presents with ongoing pain and/or disability despite non-operative care, MRI is commonly used as a diagnostic modality. To date, there is not a minimally-invasive option that can provide detailed information about the intra-articular pathology of a joint. VisionScope Imaging (VSI) is an office-based diagnostic modality that provides comprehensive real-time images and video of a joint with higher accuracy and reliability compared to static MR images. The purpose of this study was to compare the efficacy, accuracy and safety of VSI compared to MRI and surgical diagnostic arthroscopy. Methods: A prospective, blinded, multi-centered study was performed of all patients who had a routine surgical arthroscopy at one of the six participating clinical sites between July 2012 and May 2013. Patients were consented by the physician investigator at each site. Study inclusion criteria consisted of: suspected meniscal tears or articular cartilage damage. Patients were excluded from the study if they had (1) acute traumatic hemarthoses, (2) concomitant ligament injury, (3) active systemic infection, (4) allergy to silicone or any medication used during the procedure,. All patients had a MRI and a comprehensive physical exam prior to their surgical arthroscopy. Each patient underwent a MRI, VSI exam and surgical diagnostic arthroscopy. The attending physician completed standard forms comparing the VSI exam findings to the diagnostic arthroscopy findings on each patient. Two blinded experts unaffiliated with the study reviewed the VSI and MRI images. The arthroscopy served as the “control” comparison between the VSI and MRI findings. Results: There were 110 patients included in this study. The accuracy, sensitivity and specificity of VSI was equivalent to surgical diagnostic arthroscopy and more accurate than MRI (Table 1). When comparing VSI to

    Hip arthroscopy (HA) is considered to be a very difficult and demanding surgical procedure, special instruments, an image intensifier and a fracture table or hip distractor are required to access the hip joint, the most common and worldwide used HA technique is entering blindly to the central compartment with the use of fluoroscopy and continuous distraction; with the potential danger if performed in unskillful hands of labral penetrations, labral resections and scuffing of the femoral head cartilage. Our technique describes the arthroscopic management of femoroacetabular impingement (FAI), performing a preoperative planning using radiographic and anatomic landmarks to approach the anterior capsule without the use of fluoroscopy. Access to the hip joint is made extra-articularly from the peritrochanteric compartment palpating the greater trochanter and posteriorly penetrating the iliotibial band sliding the arthroscopic sheath and obturator from the trochanteric border to the anterior femoral neck to visualize the anterior capsule bursa and anterior capsule fibers and posteriorly following our previous landmarks perform an anterior oblique Inverted 'T' or 'H' capsulotomy with a radiofrequency wand to access the cam-type impingement and distraction is made under direct controlled arthroscopic vision. Our technique in HA aiming the anterior capsule using radiographic and anatomic landmarks is safe, reliable and reproducible in FAI with big cams, deep sockets and cases with mild arthritis where the capsule is thick, stiff and calcified.

    We carried out a prospective study of 53 consecutive patients who had sustained a serious wrist injury. Patients who presented with a previous condition or who had undergone surgery to the wrist were excluded. History, clinical findings, standard radiographs and arthrography were correlated with the uninjured side and with arthroscopic findings. The radiolunate (RL) angle of the injured wrist differed significantly from that of the "normal" wrist (p = 0.088). POssible correlations within the whole group were studied by multivariate analysis, particularly k-means clustering, a procedure which enables the detection of natural groups. We found that ligamentous tears at the triquetrum in the midcarpal joint significantly (p = 0.004) affected the equilibrium of the proximal row defined by clustering with the RL and scapholunate (SL) angles. The use of multivariate analysis techniques in combination with cross tabulation for the surgery of intracarpal ligamentous abnormalities seen at arthroscopy might help us to define better the function of the ligaments of the wrist. These findings, of little help in daily practice, might be important for clinical research.

  4. Septic arthritis as a severe complication of elective arthroscopy:clinical management strategies

    2009-03-01

    Full Text Available Abstract Infection of a peripheral joint following arthroscopic surgery presents with an incidence of approximately 0.42% an extremely rare entity. However, septic arthritis is a serious situation possibly leading to an irreparable joint damage. Especially at delayed diagnosis patients' safety can be endangered severely. Only few precise statements regarding diagnosis and therapy have been published so far. Besides an accurate analysis of the patient's anamnesis and the assessment of the C-reactive protein especially arthrocentesis is required for diagnostic workup. For early stage infections arthroscopic therapy is proven to be of value. In addition a calculated and consecutive germ-adjusted antibiotic therapy is essential. In case of persisting signs of infection the indication for re-arthroscopy or conversion to open revision has to be stated in time. The number of necessary revisions is dependent on the initial stage of infection. For pain therapy postoperative immobilization of the affected joint is occasionally essential, if otherwise possibly early mobilization of the joint should be performed.

    To identify the complications concerning the use of metal anchors in shoulder arthroscopic procedures. Methods: 28 shoulders of 28 patients (23 male and 5 female) have been re-operated in the period between December 1997 and August 2007, at Hospital Ortopédico, Belo Horizonte Hospital and Military Police Hospital in Belo Horizonte, MG, as a result of complications such as loose anchors and prominent anchors. The primary surgeries intended to treat 20 anterior traumatic instabilities (71.5%), one posterior instability (3.5%), one slap injury (3.5%), six procedures for treating injuries on the rotator cuff (21.5%). We used the X-ray classification suggested by Samilson and Prieto and Outerbridge arthroscopic classification for assessing patients' degree of arthrosis. All patients were evaluated by the UCLA (University of California at Los Angeles) index criteria. Results: In all patients, arthroscopic reviews were made. In two cases, after anchors removal, clinical signs of instability were seen, leading to the decision of providing open stabilization by Latarjet-Patte technique. Conclusion: the complications with metallic-suture anchors result from inappropriate surgical techniques applied in arthroscopy. PMID:26998465

    We compared naproxen sodium (550 mg) and propoxyphene napsylate with acetaminophen (PN/A, 100 mg with 650 mg) for pain relief after arthroscopy or arthroscopic meniscectomy. Fifty-two patients entered this multicenter, double-blind, randomized, parallel trial. In each drug group, pain intensity values dropped consistently throughout this six-hour study from mean baseline levels of approximately 55 on a scale of 0 to 100. Pain intensity values were lower at each hour in the naproxen sodium than in the PN/A group and significantly lower at hour 1 (P = .008). Pain intensity differences (PID, reflecting change from baseline) mirrored this trend: greater mean PIDs were seen in the naproxen sodium group at each hour, and this difference between drug groups was statistically significant at hour 1 (P = .017). One patient in the naproxen sodium group and seven patients using PN/A took a second dose within the six hours. Patients in each drug group reported five complaints. PMID:2882607

  7. Prospective, double-blind evaluation of knee MR imaging versus arthroscopy

    International Nuclear Information System (INIS)

    The significance of subtle changes in signal intensity on MR images of the meniscus is not clear, as the authors have a high rate of false-negative diagnoses using previously reported criteria. Unselected patients scheduled for knee arthroscopy were imaged in sagittal and coronal planes (repetition time/echo time = 800-1,500/20, 70 msec) with 5-mm and 3-mm section thickness, respectively. A total of 140 menisci were evaluated. The images and interpretations were withheld from the arthroscopist until the arthroscopic diagnosis was recorded so that the MR imaging results did not influence which cases received arthroscopic confirmation. Before the arthroscope was withdrawn the MR images and interpretations were unsealed so that additional arthroscopic evaluation could be obtained of areas suspicious on MR imaging. Review of the first 60 menisci showed that significant tears of the meniscus were often represented by subtle signal intensity that did not extend to the surface of the meniscus. When previously reported criteria were used, approximately 50% of those menisci with increased internal signal not extending to the surface were interpreted as false-negative diagnoses. An initial classification system based on ten categories of signal morphology was developed which reduced the false-negative rate to 10% but led to a 30% rate of false-positive diagnoses in those cases with equivocal signal. Retrospective, blinded categorization of signal morphology was optimized based on ROC curves, and this is being tested prospectively in an ongoing investigation

    Magnetic resonance imaging (MRI) is useful in the diagnosis of meniscal lesions of the knee. The purpose of this study was to relate the findings of MRI and arthroscopy and to evaluate the morphology of the menisci with tears. 39 patients of both genders were included, whose age range was 13 to 74 years old (mean: 42.6 years), with and without a history of trauma, who underwent MRI and arthroscopy of the knee, due to symptoms of articular lesion. The images of magnetic resonances were analyzed independently by two specialists prior to the arthroscopy. The measurements of the medial and lateral menisci were made in each meniscal horn with sagital images in protonic density and fat-suppression. MRI detected 8 cases of tear of the lateral meniscus of the 11 catalogued by arthroscopy, and 11 cases of tears of the medial meniscus of the 13 catalogued by arthroscopy. The sensibility and specificity of MRI for the lateral meniscal tears were 72% and 100%, and for the medial tears were 85% and 89%. The meniscal tears were localized mainly in the posterior horn. The dimensions of the posterior horn of the lateral meniscus were larger in disrupted menisci (height, 7.1 +/- 1.3 mm vs. 6.1 +/- 0.7 mm, p meniscal tear produces morphological changes, particularly in the posterior horn of the lateral meniscus. Magnetic resonance constitutes the imaging technique of choice for the diagnosis of the meniscal tears.

    Highlights: • MR is the preferred imaging modality for diagnosing acetabular labral tears. • The diagnostic performance of MR arthrography are superior than conventional hip MR. • The hip MR arthrography is recommended for diagnosing acetabular labral lesions. - Abstract: Objective: To evaluate the value of hip MR for diagnosing acetabular labrum tears, and to further compare the diagnostic performances of conventional MR with MR arthrography in acetabular labrum tears. Methods: 90 patients undergoing both hip MR examination and subsequent hip arthroscopy were retrospectively evaluated. Of these patients, 34 accepted both conventional MR and MR arthrography; while the other 56 only underwent conventional MR examination. All hip MR images were independently reviewed by two radiologists, and further compared with the results of hip arthroscopy. Results: 59 of 90 patients were confirmed with acetabular labral tears by hip arthroscopy and 31 without tears. The sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) of conventional MR for evaluating the acetabular labral tears were 61.0%, 77.4%, 83.7% and 51.1% (radiologist A), and 66.1%, 74.2%, 82.9% and 53.4% (radiologist B), respectively, with good consistency between the two observers (K = 0.645). The sensitivity, specificity, PPV and NPV of MR arthrography for assessing the acetabular labral tears were 90.5%, 84.6%, 90.5% and 84.6% (radiologist A), and 95.2%, 84.6%, 90.9% and 91.7% (radiologist B), respectively, with excellent good consistency between the two observers (K = 0.810). The sensitivity and NPV of MR arthrography for diagnosing the acetabular labral tears were significantly higher than those of conventional MR (both P < 0.05). Conclusion: Hip MR arthrography is a reliable evaluation modality for diagnosing the acetabular labral tears, and its diagnostic performance is superior to that of conventional MR at 3.0 T.

    Arthroscopy has surpassed traditional types of open surgery in the treatment of shoulder instability because of its mini-invasiveness and shorter rehabilitation time. Despite this, in some cases, such as those involving significant glenoid erosions and extensive capsular lesions, arthroscopic methods fail the objectives, and methods that were believed to have been surpassed are again used, such as the Bristow-Laterjet procedure. It is the purpose of this article to describe use of the method in light of the possibilities offered by arthroscopy.

    Isolated ACL reconstructions were performed in 138 patients between 1994 and 1998. Patellar bone-patellar tendon-bone, and hamstring tendon autografts were used in 88 patients, and allografts were used in 50 patients. Eighty-eight knees of 88 patients with autograft reconstructions (17 female, 71 male) were included in this study and evaluation of the patients with allograft reconstruction reported separately. The mean age at the time of the operation was 32 years. All ACL reconstructions were performed arthroscopically. Twenty-seven bone-patellar tendon-bone, and 61 hamstring tendon autografts were used. The mean follow-up was 29 months. In the postoperative course the Lachman test was negative in 62 patients, 1+ in 22 patients, and 2+ in 4 patients. In 17 patients, anterior drawer sign were 1+ in comparison to the contralateral side. Pivot shift test was moderately positive only in 5 cases in the bone-patellar tendon-bone and hamstring tendon autograft groups postoperatively. There were 3 patients with subjective "giving way" symptoms. Second look arthroscopy revealed rupture of the neo-ligament. Arthroscopic washout and debridement were performed, and no revision ligamentoplasties were performed. Two of these patients improved with accelerated proprioceptive physical therapy, and one had to decrease his previous level of activity. There were no cases of arthrofibrosis, infection, or extension lag. Clinical results of patellar bone-tendon-bone and hamstring groups did not show any significant clinical difference. Avoiding the disturbance of the extensor mechanism of the knee is probably the most significant advantage of the hamstring autograft.

    Full Text Available INTRODUCTION: Shoulder arthroscopy is a common orthopedics procedure performed on day - case basis. Adequate pain relief reduces surgical stress response, patient’s morbidity and improves postoperative recovery and rehabilitation. Various drugs have been tried intra - articularly t o provide postoperative analgesia. PURPOSE: We studied analgesic effect of dexamethasone 16mg (4ml with ropivacaine and compared it with ropivacaine intra - articularly in shoulder arthroscopic procedures in search of the ideal analgesic combination. METHODS: A Prospective Multicenter Double Blind study on 60 patients undergoing arthroscopic shoulder surgery from July’13 - April’14. Patients were assigned into 3 groups randomly - Group I (20 ml normal saline,Group II (20 ml 0.2% ropivacaine and Group III (16 ml 0.2% of ropivacaine & dexamethasone - 4 ml containing 16 mg. VARIABLES ASSESSED: Analgesic effect (VAS Score, time to first postoperative analgesic request, Analgesic used during first 24 hours. RESULTS: Group III had significant low pain scores for 1 st 20 hours as compared to Group II and Group I. Time to first analgesic requirement was longest in Group III (1356.2±193.10mins (p<0.01. Intensity of pain &Total analgesic requirement was significantly less in Group III (38.2±27.83 mg(p<0.01 in comparison to Group II and I. No significant side - effects were noted. CONCLUSION: A16 mg (4ml dosage of Dexamethasone is safe, cost effective and free from relative side effects, has a better patient compliance in terms of post - operative pain, need for analgesia and should be used routinely in arthroscopic shoulder surgeries. Helps in the recovery of patients to the pre - operative level.

Pivot shift test was moderately positive only in 5 cases in the bone-patellar tendon-bone and hamstring tendon autograft groups postoperatively. There were 3 patients with subjective "giving way" symptoms. Second look arthroscopy revealed rupture of the neo-ligament. Arthroscopic washout and debridement were performed, and no revision ligamentoplasties were performed. Two of these patients improved with accelerated proprioceptive physical therapy, and one had to decrease his previous level of activity. There were no cases of arthrofibrosis, infection, or extension lag. Clinical results of patellar bone-tendon-bone and hamstring groups did not show any significant clinical difference. Avoiding the disturbance of the extensor mechanism of the knee is probably the most significant advantage of the hamstring autograft. PMID:10983256

    Health care facilities produce significant waste (2200 kg/bed/year) creating 2% of greenhouse gas emissions and 1% total solid waste nationwide, with 20-70% of waste coming from operating rooms. We performed a waste audit of hip arthroscopy for femoroacetabular impingement (FAI) to understand its environmental impact and identify areas for greening practices. A waste audit of five hip arthroscopy procedures for FAI was performed. All waste was collected and separated into six waste streams in real time: (i) normal/landfill waste; (ii) recyclable cardboards and plastics; (iii) biohazard waste; (iv) sharp items; (v) linens and (vi) sterile wrapping. The surgical waste (except laundered linens) from five FAI surgeries totaled 47.4 kg, including 21.7 kg (45.7%) of biohazard waste, 11.7 kg (24.6%) of sterile wrap, 6.4 kg (13.5%) of normal/landfill waste, 6.4 kg (13.5%) of recyclable plastics and 1.2 kg (2.6%) of sharp items. An average of 9.4 kg (excluding laundered linens) of waste was produced per procedure. Given the considerable biohazard waste produced by FAI procedures, additional recycling programs, continued adherence to proper waste segregation and an emphasis on 'green outcomes' is encouraged to demonstrate environmental responsibility and effectively manage and allocate finite resources.

    Abstract: The optimum anaesthetic and analgesic management following hip arthroscopy is yet to be determined. There is, in addition, some concern over the use of intraarticular local anaesthetic. We compared the analgesic efficacy of intra-articular infiltration compared with portal infiltration of bupivacaine following hip arthroscopy. Patients were randomised to receive either 10ml of 0.25% bupivacaine either into the joint or around the portal sites following completion of surgery. 73 patients were recruited (40 intra-articular). The portal infiltration group required significantly more rescue analgesia immediately after surgery (2.33mg vs.0.57mg, p=0.036). Visual Analogue Scale pain scores were not significantly different at 1 and 2 hours following surgery, but at 6 hours the portal group had significantly lower VAS scores (p=0.0036). We believe that the initial pain following surgery results from capsular injury and this explains the need for more rescue analgesia in the portal infiltration group. Further work is needed to establish the ideal regimen. A combination of portal and intra-articular infiltration may be the most efficacious.

    Full Text Available Background and Aims: Sudden, profound hypotension and bradycardia events (HBEs have been reported in more than 20% of patients undergoing shoulder arthroscopy in the sitting position. The present study was designed to know whether intravenous (IV ondansetron (selective 5-hydroxy tryptamine 3-antagonist can help in reducing the HBEs associated with shoulder arthroscopy performed in sitting position under interscalene brachial plexus block (ISBPB. Methods: A total of 100 patients (age 20-50 years undergoing shoulder arthroscopy performed in the sitting position under ISBPB were assigned randomly to one of the two groups: Group C received 10 ml of normal saline and Group T received 4 mg of ondansetron diluted in 10 ml of normal saline` IV. All patients received ISBPB using levobupivacaine 0.5%. Assessment of motor and sensory blockade, pulse rate, systolic blood pressure, respiration, and side effects were noted every 5 min for first 30 min and every 10 min till the end of surgery. HBEs were recorded in both groups. Results: IV injection of ondansetron significantly reduces the incidence of HBEs from 11 (22.44% in Group C to 3 (6.1% in Group T. The duration of analgesia was significantly longer in Group C (8.1 ± 3.3 in comparison with Group T (6.3 ± 4.2 h. Conclusion: We conclude that 4 ml of IV ondansetron can significantly reduce the HBEs during shoulder arthroscopy done in the sitting position under ISBPB.

    Full Text Available Abstract Background Surgery for type II SLAP (superior labral anterior posterior lesions of the shoulder is a promising but unproven treatment. The procedures include labral repair or biceps tenodesis. Retrospective cohort studies have suggested that the benefits of tenodesis include pain relief and improved function, and higher patient satisfaction, which was reported in a prospective non-randomised study. There have been no completed randomised controlled trials of surgery for type II SLAP lesions. The aims of this participant and observer blinded randomised placebo-controlled trial are to compare the short-term (6 months and long-term (2 years efficacy of labral repair, biceps tenodesis, and placebo (diagnostic arthroscopy for alleviating pain and improving function for type II SLAP lesions. Methods/Design A double-blind randomised controlled trial are performed using 120 patients, aged 18 to 60 years, with a history for type II SLAP lesions and clinical signs suggesting type II SLAP lesion, which were documented by MR arthrography and arthroscopy. Exclusion criteria include patients who have previously undergone operations for SLAP lesions or recurrent shoulder dislocations, and ruptures of the rotator cuff or biceps tendon. Outcomes will be assessed at baseline, three, six, 12, and 24 months. Primary outcome measures will be the clinical Rowe Score (1988-version and the Western Ontario Instability Index (WOSI at six and 24 months. Secondary outcome measures will include the Shoulder Instability Questionnaire (SIQ, the generic EuroQol (EQ-5 D and EQ-VAS, return to work and previous sports activity, complications, and the number of reoperations. Discussion The results of this trial will be of international importance and the results will be translatable into clinical practice. Trial Registration [ClinicalTrials.gov NCT00586742

    Objective: To evaluate fat-suppressed (FS) proton-density-weighted (PDw) turbo spin-echo (TSE) magnetic resonance imaging for the detection of anterior and posterior cruciate ligament lesions in comparison to arthroscopy. Materials and methods: In a prospective study 31 knee joints were imaged on a 1.5 T MR scanner (Vision[reg], Siemens, Erlangen) prior to arthroscopy using following sequences: (a) sagittal FS-PDw/T2w TSE (TR/TE: 4009/15/105 ms); (b) sagittal PDw/T2w TSE (TR/TE:3800/15/105 ms). Further imaging parameters: slice thickness 3 mm, FOV 160 mm, matrix 256 x 256. A total of 62 anterior and posterior cruciate ligaments (ACL/PCL) were evaluated, standard of reference was arthroscopy. Sensitivity, specificity, positive (ppv) and negative predictive value (npv) and accuracy were calculated. Results: Twenty-one cruciate ligament ruptures were detected in arthroscopy, 19 ACL- and 2 PCL-ruptures (on MRI 34/124, 25/62 ACL, 9/62 PCL lesions). For all four sequences in the 31 patients with arthroscopic correlation sensitivity, specificity, ppv, npv and accuracy were 86%, 98%, 95%, 93% and 94% for detection of tears, and 84%, 100%, 100%, 80% and 90% for ACL-ruptures respectively. The two PCL-ruptures were true positive in all sequences, one intact PCL was diagnosed as torn (false positive). Conclusions: Fat-suppressed PDw/T2w TSE-MR sequences are comparable to PDw TSE sequences for the detection of ACL/PCL-lesions.

    The role of arthroscopy in the treatment of soft-tissue injuries associated with proximal tibial fractures remains debatable. Our hypothesis was that MRI over-diagnoses clinically relevant associated soft-tissue injuries. This prospective study involved 50 consecutive patients who underwent surgical treatment for a split-depression fracture of the lateral tibial condyle (AO/OTA type B3.1). The mean age of patients was 50 years (23 to 86) and 27 (54%) were female. All patients had MRI and arthroscopy. Arthroscopy identified 12 tears of the lateral meniscus, including eight bucket-handle tears that were sutured and four that were resected, as well as six tears of the medial meniscus, of which five were resected. Lateral meniscal injuries were diagnosed on MRI in four of 12 patients, yielding an overall sensitivity of 33% (95% confidence interval (CI) 11 to 65). Specificity was 76% (95% CI 59 to 88), with nine tears diagnosed among 38 menisci that did not contain a tear. MRI identified medial meniscal injuries in four of six patients, yielding an overall sensitivity of 67% (95% CI 24 to 94). Specificity was 66% (95% CI 50 to 79), with 15 tears diagnosed in 44 menisci that did not contain tears. MRI appears to offer only a marginal benefit as the specificity and sensitivity for diagnosing meniscal injuries are poor in patients with a fracture. There were fewer arthroscopically-confirmed associated lesions than reported previously in MRI studies. PMID:25452365

    The purpose of this study was to evaluate the relationship between mucoid hypertrophy of the anterior cruciate ligament (ACL) and morphologic change of the intercondylar notch. We retrospectively reviewed the 105 patients with knee magnetic resonance imaging (MRI) with or without knee arthroscopy [group 1: patients with arthroscopic notchplasty (N = 47), group 2: knee arthroscopy demonstrating intact ACL (N = 33), and group 3: patients with normal knee MRI but no arthroscopy (N = 25)]. Groups 2 and 3 served as an arthroscopic and MR control group, respectively. Two musculoskeletal radiologists reviewed all MR examinations. The intercondylar notch width, notch index (width of intercondylar notch/width of femoral condyle), transverse notch angle (TNA), sagittal notch angle (SNA), and notch area were recorded on axial and sagittal MR images at the midpoint of Blumensaat's line which was identified on sagittal images. The diameter of the ACL was recorded on coronal MR images at the posterior end of Blumensaat's line. The mean values of the intercondylar notch width, notch index, TNA, SNA, notch area, and ACL diameter for the three groups were 16.0 mm/0.2/50.3 /36.5 /249.0 mm{sup 2}/7.7 mm (group 1); 19.3 mm/0.3/52.9 /40.2 /323.4 mm{sup 2}/4.8 mm (group 2); and 20.3 mm/0.3/51.4 /39.1 /350.8 mm{sup 2}/4.5 mm (group 3). The intercondylar notch width, notch index, SNA, and notch area were smaller, and ACL diameter was thicker in group 1 compared with the other groups (p < 0.05). Patients with mucoid ACL hypertrophy show a narrower notch, a steeper notch angle, and a smaller notch area than control groups. (orig.)

    Full Text Available ABSTRACT OBJECTIVES: To ascertain the sensitivity, specificity, accuracy and concordance of the physical examination (PE and magnetic resonance imaging (MRI in comparison with arthroscopy, in diagnosing knee injuries. METHODS: Prospective study on 72 patients, with evaluation and comparison of PE, MRI and arthroscopic findings, to determine the concordance, accuracy, sensitivity and specificity. RESULTS: PE showed sensitivity of 75.00%, specificity of 62.50% and accuracy of 69.44% for medial meniscal (MM lesions, while it showed sensitivity of 47.82%, specificity of 93.87% and accuracy of 79.16% for lateral meniscal (LM lesions. For anterior cruciate ligament (ACL injuries, PE showed sensitivity of 88.67%, specificity of 94.73% and accuracy of 90.27%. For MM lesions, MRI showed sensitivity of 92.50%, specificity of 62.50% and accuracy of 69.44%, while for LM injuries, it showed sensitivity of 65.00%, specificity of 88.46% and accuracy of 81.94%. For ACL injuries, MRI showed sensitivity of 86.79%, specificity of 73.68% and accuracy of 83.33%. For ACL injuries, the best concordance was with PE, while for MM and LM lesions, it was with MRI ( p < 0.001. CONCLUSIONS: Meniscal and ligament injuries can be diagnosed through careful physical examination, while requests for MRI are reserved for complex or doubtful cases. PE and MRI used together have high sensitivity for ACL and MM lesions, while for LM lesions the specificity is higher.

    Full Text Available Abstract Background In patients with osteoarthritis, a detailed assessment of degenerative cartilage disease is important to recommend adequate treatment. Using a representative sample of patients, this study investigated whether MRI is reliable for a detailed cartilage assessment in patients with osteoarthritis of the knee. Methods In a cross sectional-study as a part of a retrospective case-control study, 36 patients (mean age 53.1 years with clinically relevant osteoarthritis received standardized MRI (sag. T1-TSE, cor. STIR-TSE, trans. fat-suppressed PD-TSE, sag. fat-suppressed PD-TSE, Siemens Magnetom Avanto syngo MR B 15 on a 1.5 Tesla unit. Within a maximum of three months later, arthroscopic grading of the articular surfaces was performed. MRI grading by two blinded observers was compared to arthroscopic findings. Diagnostic values as well as intra- and inter-observer values were assessed. Results Inter-observer agreement between readers 1 and 2 was good (kappa = 0.65 within all compartments. Intra-observer agreement comparing MRI grading to arthroscopic grading showed moderate to good values for readers 1 and 2 (kappa = 0.50 and 0.62, respectively, the poorest being within the patellofemoral joint (kappa = 0.32 and 0.52. Sensitivities were relatively low at all grades, particularly for grade 3 cartilage lesions. A tendency to underestimate cartilage disorders on MR images was not noticed. Conclusions According to our results, the use of MRI for precise grading of the cartilage in osteoarthritis is limited. Even if the practical benefit of MRI in pretreatment diagnostics is unequivocal, a diagnostic arthroscopy is of outstanding value when a grading of the cartilage is crucial for a definitive decision regarding therapeutic options in patients with osteoarthritis.

    Full Text Available Canine elbow dysplasia (CED is a complex of diseases resulting in osteoarthritis (OA. CED includes ununited anconeal process (UAP, fragmented medial coronoid process (FMCP, osteochondritis (OC of the medial humeral condyle, and elbow incongruity. A patient with OC of the medial humeral condyle and FMCP was treated by arthroscopy for micro-fractures of subchondral bone and removal, respectively, and received intra-articular doses of autologous platelet concentratres (APC. The patient was evaluated by clinical examination, synovial fluid cytology, radiographic assessment and platform force evaluation, before surgery and at 30, 60 and 90th postoperative days. The patient reached full clinical recovery at 60th postoperative day with improvement in the synovial fluid cytology and the kinematic findings. However, radiological evaluation showed a progressive development of OA. Results from this report may suggest the potential-use of APC as a symptomatic modifying therapy in the treatment of OA secondary to elbow dysplasia in the dog.

    contrast, age, pain intensity, disability, and pain-associated psychological factors did not differ between pre-op PT treatment groups (P>0.05. Subacromial bursectomies were more commonly performed in patients having pre-op PT treatment (P<0.05. Pre-op PT treatment did not influence length of post-op PT treatment and did not affect 3-month and 6-month pain intensity and disability outcomes. Differences in distribution of pre-op PT for males and females and subacromial bursectomy did not influence 3-month or 6-month postsurgical outcomes. Conclusion: Receiving pre-op PT treatment did not influence post-op PT treatment or pain and disability outcomes at 3 months and 6 months. This prospective cohort study provides no evidence of benefit for pre-op PT on post-op PT treatment or postsurgical outcomes. Females or patients receiving certain surgical procedures are more likely to undergo pre-op PT treatment. However, these differences did not influence postoperative outcomes in this cohort.

    2006-05-01

    All simple arthroscopic procedures during 1999 through 2001 performed at Baerum community hospital were retrospectively examined. Procedures were excluded when being part of more complex procedures. A total of 876 procedures performed on 785 patients were left for examination. Complications were registered from the patient record and all received a written questionnaire or phone call. The answer was obtained from 97.6%. The overall complications rate was low, giving total of 5.00%. A total of 0.68% of the complications had therapeutic consequences. There were two superficial infections, one thromboembolic event/pulmonary embolus and one reoperation due to scar tissue. Other complications were considered minor, and had none or little consequence for the patient comprising preoperative bradycardial episodes, asthmatic events, subcutaneous infusion of total intravenous anaesthetics (TIVA), instrument breakage and conversion to arthrotomi. Postoperatively registered complications included swelling, haemarthros, portal bleeding and fistulation, temporary sensory loss and longstanding pain. Duration of surgery was the only predicting factor for postoperative complications. Simple arthroscopic surgery is safe and has few serious complications. The use of TIVA or tourniquet does not increase the morbidity or complication rate, and prophylaxis against thromboembolism was not necessary. PMID:16208459

    The International Society for Hip Arthroscopy (ISHA) Annual Scientific Meeting is at the forefront of informing today’s orthopaedic surgeons and society of the rapid advances in the exponentially growing field of hip arthroscopy. The purpose of this study was to evaluate and observe any trends in the level of clinical evidence in the papers and posters presented at the ISHA Annual Scientific Meeting from 2010 to 2014. The online abstracts of the paper and poster presentations presented at the ISHA Annual Scientific Meetings were independently evaluated by two reviewers (582 total resulting presentations). Two reviewers screened these results for clinical studies and graded the quality of evidence from level I (i.e. randomized trials) to IV (i.e. case series) based on the American Academy of Orthopaedic Surgeons classification system. Four hundred and twenty-eight presentations met the inclusion criteria and were evaluated. Overall, 10.1% of the presentations were level I, 12.8% were level II, 30.1% were level III and 47.0% were level IV evidence. Over time, from 2010 to 2014, we observed an increase in the percentage of level II paper presentations, an increase in the proportion of level III poster presentations, and a decrease in the proportion of both level IV paper and poster presentations. Significant non-random improvement in the level of evidence presented was noted for the poster presentations (P = 0.012) but not for the paper presentations (P = 0.61) over the study period. Statistical trends demonstrate ISHA’s increased awareness and commitment to presenting higher quality evidence as the availability of this evidence increases. PMID:27011857

    Full Text Available Abstract Background Ankle sprains are common in sports and can sometimes result in a persistent pain condition. Purpose Primarily to evaluate clinical symptoms, signs, diagnostics and outcomes of surgery for symptomatic chondral injuries of the talo crural joint in athletes. Secondly, in applicable cases, to evaluate the accuracy of MRI in detecting these injuries. Type of study: Prospective consecutive series. Methods Over around 4 years we studied 61 consecutive athletes with symptomatic chondral lesions to the talocrural joint causing persistent exertion ankle pain. Results 43% were professional full time athletes and 67% were semi-professional, elite or amateur athletes, main sports being soccer (49% and rugby (14%. The main subjective complaint was exertion ankle pain (93%. Effusion (75% and joint line tenderness on palpation (92% were the most common clinical findings. The duration from injury to arthroscopy for 58/61 cases was 7 months (5.7–7.9. 3/61 cases were referred within 3 weeks from injury. There were in total 75 cartilage lesions. Of these, 52 were located on the Talus dome, 17 on the medial malleolus and 6 on the Tibia plafond. Of the Talus dome injuries 18 were anteromedial, 14 anterolateral, 9 posteromedial, 3 posterolateral and 8 affecting mid talus. 50% were grade 4 lesions, 13.3% grade 3, 16.7% grade 2 and 20% grade 1. MRI had been performed pre operatively in 26/61 (39% and 59% of these had been interpreted as normal. Detection rate of cartilage lesions was only 19%, but subchondral oedema was present in 55%. At clinical follow up average 24 months after surgery (10–48 months, 73% were playing at pre-injury level. The average return to that level of sports after surgery was 16 weeks (3–32 weeks. However 43% still suffered minor symptoms. Conclusion Arthroscopy should be considered early when an athlete presents with exertion ankle pain, effusion and joint line tenderness on palpation after a previous sprain

  3. Deltoid ligament and tibiofibular syndesmosis injury in chronic lateral ankle instability: Magnetic resonance imaging evaluation at 3T and comparison with arthroscopy

    International Nuclear Information System (INIS)

    To evaluate the prevalence of deltoid ligament and distal tibiofibular syndesmosis injury on 3T magnetic resonance imaging (MRI) in patients with chronic lateral ankle instability (CLAI). Fifty patients (mean age, 35 years) who had undergone preoperative 3T MRI and surgical treatment for CLAI were enrolled. The prevalence of deltoid ligament and syndesmosis injury were assessed. The complexity of lateral collateral ligament complex (LCLC) injury was correlated with prevalence of deltoid or syndesmosis injuries. The diagnostic accuracy of ankle ligament imaging at 3T MRI was analyzed using arthroscopy as a reference standard. On MRI, deltoid ligament injury was identified in 18 (36%) patients as follows: superficial ligament alone, 9 (50%); deep ligament alone 2 (11%); and both ligaments 7 (39%). Syndesmosis abnormality was found in 21 (42%) patients as follows: anterior inferior tibiofibular ligament (AITFL) alone, 19 (90%); and AITFL and interosseous ligament, 2 (10%). There was no correlation between LCLC injury complexity and the prevalence of an accompanying deltoid or syndesmosis injury on both MRI and arthroscopic findings. MRI sensitivity and specificity for detection of deltoid ligament injury were 84% and 93.5%, and those for detection of syndesmosis injury were 91% and 100%, respectively. Deltoid ligament or syndesmosis injuries were common in patients undergoing surgery for CLAI, regardless of the LCLC injury complexity. 3T MRI is helpful for the detection of all types of ankle ligament injury. Therefore, careful interpretation of pre-operative MRI is essential

    Objective To investigate the clinical value of arthroscopy in the treatment of dorsal carpal ganglion. Methods A total of 22 cases of dorsal carpal ganglion was treated from September 2009 to May 2013.With 4/5 or 6R portal access as arthroscopy vision, 1/2 portal access as working pathway, and 6U for outflow, the scapholunate interosseous ligament ( SLIL) was found and then the examination was carried out toward dorsal part till the reentry point of SLIL and dorsal carpal articular capsule. Pedicles of dorsal carpal ganglion were exposed, and the pedicles and part of articular capsules were removed by planer tools.The joint fluid was cleaned till the ganglion disappeared.Then absorbable sutures were used to close subcutaneous tissues.Pressure bandaging was given.After the operation, a supporter was used to fix the wrist for 3 weeks, during which massage and restorative exercise were conducted. Results Conversion to open surgery was required in 2 cases because the pedicles of dorsal carpal ganglion were not found in intraoperative arthroscopic examinations, including the cyst originated in the extensor tendon in 1 case and originated in the mediocarpal joint in 1 case.The remaining 20 cases underwent treatment under arthroscopy successfully.The patients were followed up for 6-14 months, with an average of 9.2 months.The wrists were normal in appearance and fully functional without obvious scars. Three cases developed recurrence, 1 of which was not given further intervention because the cyst was too tiny to be found at neutral position, and 2 of which were given open resections. Conclusions Although arthroscopic treatment of dorsal carpal ganglion has a relatively high equipment and technical requirements and has certain limitations on indications, the surgery is safe with few complications and good appearance.It can be used as a treatment option for some young women with strong cosmetic requirements.%目的:探讨关节镜治疗腕背侧腱鞘

    Tibial plateau fractures belong to intra-articular fractures of the main weight-bearing joints of lower limbs. Traumatic osteoarthritis of the knee is mainly caused by articular surface collapse, joint deformities and joint instabilities after fractures. Therefore, the ideal target in the treatment of tibial plateau fractures is to obtain stable and painless knee joints with good counterpoint and alignment and normal range of motion, and to minimize the occurrence of traumatic osteoarthritis. In recent years, the widespread use of arthroscopic technique promotes the new progress in the diagnosis and treatment of tibial plateau fractures.

Recently,we started to conduct elbow arthroscopic fracture reduction and internal fixation,and found that due to the varying types of fracture morphologies and locations,the conventional lateral elbow approach sometimes cannot access satisfactory fixation angles.Due to the narrow space in the elbow joint and complex anatomical relationship of the peripheral nerves,nerve injury is common in elbow surgery and consequences are often serious.Therefore,we aim to explore better approaches to protect the radial nerve based on study of anatomical specimens. Here we used either an improved anterolateral elbow approach that entered at a more

    Objective To investigate the clinical diagnosis and the results of arthroscopic treatment for acetabular labrale tears. Methods From November 2008 to December 2009, 21 patients with unilateral acetabular labrale tears underwent hip arthroscopy were entered in the study, including 9 males and 12 females with an average age of 37.1 years. Physical examination, X-ray examination and magnetic resonance arthrography (MRA) were carried out preoperatively to make the definite diagnosis. Of 21 cases, including labrale debridement in 14 cases, labrale debridement plus femoral osteoplasty in 5 cases and labrale repair plus osteoplasty in 2 cases. Patients were followed-up either by telephone inquiring or out-patient interview.The visual analogue scale (VAS) and Harris hip score were recorded before operation and 6 months after operation respectively. Results All 21 patients showed a positive Fadir impingement sign on the affected hips,meanwhile 15 cases showed a positive Fabir impingement sign, and positive McCarthy test was observed in 9cases. X-ray film showed 11 cases have cam type impingement, among which 6 combined with pincer type impingement. Two cases had acetabulum retroversion alone. On MRA images, signals of contrast agent infiltration in anterior superior quadrant which indicated labrale tear were observed among all cases. All labrale tears were confirmed under arthroscopy. All patients were followed up for average 11.6 months (range, 6-19).The symptoms were obviously released after operation. The VAS decreased from (5.3±1.3) preoperatively to (1.4±-0.9) 6 months postoperatively. The mean Harris hip score improved from (63±9) preoperatively to (84±10) 6 months postoperatively. All the differences had statistical significance. Conclusion Acetabular labrale injury has a close correlation with femoroacetabular impingement.

    Objective: In literature the diagnostic value of MRI for detecting lesions of the carpal ligaments and the TFCC is judged controversially. The aim of the following study is to determine the diagnostic accuracy of direct MR arthrography for depicting and staging of intraarticular lesions of the wrist. Material and methods: One day before undergoing arthroscopy, 125 patients suffering from wrist pain were examined with direct MR arthrography in a prospective and blinded study. A mixture of contrast medium (iodine-containing contrast medium and gadopentetate in relation 200:1) was injected into both radiocarpal and midcarpal joints. The following sequences were acquired on a 1.5T scanner: coronal T1-weighted SE, coronal fat-saturated T1-weighted SE, coronal T1-/T2*-DESS-3D, and sagittal T2*-weighted MEDIC. MRI results were compared with arthroscopic findings using statistical analysis (SEN=sensitivity, SPE=specificity, PPV=positive predictive value, NPV=negative predictive value, ACC=accuracy). Results: In comparison to arthroscopy as the accepted diagnostic gold standard, the following results were found for MR arthrography. Detection of TFCC lesions: SEN 97.1%, SPE 96.4%, PPV 97.1%, NPV 96.4%, ACC 96.8%. Detection of complete tears of the scapholunate ligament: SEN 91.7%, SPE 100%, PPV 100%, NPV 99.1%, ACC 99.2%. Detection of partial tears: SEN 62.5%, SPE 100%, PPV 100%, NPV 94.8%, ACC 95.2%. Detection of cartilage defects: SEN 84.2%, SPE 96.2%, PPV 80%, NPV 97.1%, ACC 94.4%. In total, only three lesions of the lunotriquetral ligament were present. Conclusion: Direct MR arthrographic imaging is well suited for detecting intraarticular lesions of the wrist. The presented diagnostic results of MR arthrography are superior to the results of unenhanced MRI reported in the literature. Direct MR arthrography as a reliable diagnostic tool is strongly recommended if lesions of the scapholunate ligament and the triangular fibrocartilage complex are suspected. In contrast, an

    Sisto, Domenick J.; Blazina, Martin E.; Hirsh, Linda C.

    1994-09-01

    The HO:YAG laser is a near-contact laser with a capacity to ablate or cut tissues. The ablation function allows the surgeon to remove meniscal tissue, lyse and resect adhesions, melt loose bodies, and dissolve inflamed synovium. The cutting function of the laser is utilized to perform a lateral release or resect torn menisci. The laser can also be utilized to drill holes in Grade IV chondromalacic lesions to initiate a healing response. The laser has been embraced by orthopaedic surgeons because of its shape and versatility. The tip is only 2 mm wide and can be delivered into the tight posterior compartments of the knee with no damaging contact with the articular surfaces. The laser coagulates as it works and bleeding is minimized. The laser can function both as a cutting and ablating tool. The laser can also drill holes into subchondral bone to, hopefully, initiate a healing response.

Methods From January 2008 to December 2009, 41 patients with ACL injuries in accordance with the inclusion criteria were treated. They were randomly divided into 2 groups according to different treatment methods. In the trial group, ACL reconstruction using achilles tendon allograft with attached calcaneus was performed on 21 patients. In the control group, ACL reconstruction using simple tendon allograft was performed on 20 patients. There were no significant differences in such general data as the age, gender, cause of injury, disease duration, preoperative functional score and so on between the 2 groups (P>0.05), which were comparable. The single-bundle and single-tunnel ACL reconstruction was performed in both groups. Results All the incisions in both groups were healed by the first intention 2 weeks postoperatively. The patients were followed up for an average period of 26 months (range; 24-28 months) in the trial group, and 28 months (range; 24-30 months) in the control group. 2 years after the operation, 15 cases (71.4%) were negative in the Lachman test, and 16 cases (76.2%) were negative in the anterior drawer test in the trail group. In contrast, 14 cases (70.0%) and 15 cases (75.0%) were negative respectively in the control group. There were no significant differences in the Lysholm score and International Knee Documentation Committee (IKDC) score between the 2 groups 2 years after the operation (P>0.05). The CT exam showed the bone tunnel diameter was enlarged in different degrees in both groups 2 years after the operation, when compared with that 1 month postoperatively. However, the rate of bone tunnel enlargement in the trial group (4/21, 19.0%) was obviously less than

    Septic arthritis of the wrist is a diagnostic and therapeutic emergency. Synovectomy and lavage by arthrotomy is often followed by stiffness. The purpose of this study was to evaluate the diagnostic and therapeutic contribution of emergency arthroscopic synovectomy with intraarticular lavage. Nine patients were operated on for wrist pathology with septic appearance. All had signs of local inflammation, three showed locoregional inflammation, three were febrile. In one patient several joints were involved. Seven patients presented with inflammatory or degenerative arthritis. All patients underwent emergency surgery using radiocarpal joint puncture, arthroscopic exploration, intraarticular lavage and synovectomy at both the radiocarpal and midcarpal joints. The results were evaluated by pain, Quick DASH, grip strength, and wrist range of motion. In three cases, joint fluid appeared clear, in three it was turbid, and in three purulent. Gram stain and culture revealed bacteria in four cases. Synovitis was radiocarpal four times, radiocarpal and midcarpal once. In one case, there was radiocarpal and midcarpal chondritis. Average pain was 5.3/10 preoperatively and 2/10 at the last clinical follow-up visit. Mean grip strength was 23.3 kg on the involved side vs. 33.5 kg on the opposite one. Mean flexion was 55° for the involved wrist vs. 68°; mean extension was 52° for the affected wrist vs. 59°. No patient was reoperated on. In all cases, there was no sign of local inflammation, regional lymphadenopathy or systemic infection at the last follow-up. One patient died of colon metastatic cancer. Another patient developed a severe Complex Regional Pain Syndrome type I (CRPS1). Our results suggest three principles of management of wrist arthritis with septic appearance: extended surgical indication, emergency operation and arthroscopic procedure.

    Full Text Available O trabalho teve por objetivo avaliar artroscopicamente a articulação do joelho de ovinos hígidos em diferentes idades, com o intuito de determinar, de acordo com os portais estabelecidos, a capacidade de observação das estruturas. Utilizaram-se 18 animais da raça Santa Inês, divididos em três grupos experimentais eqüitativos, conforme a idade cronológica, sendo: Grupo I, 6-8 meses (peso médio de 25 kg; Grupo II, 2 anos (peso médio de 50 kg; e Grupo III, 3,5-5 anos (peso médio de 55 kg. Foram estabelecidos três portais: (1 portal artroscópico primário, craniolateral; (2 portal para fluxo de drenagem; e (3 portal instrumental, craniomedial. Identificaram-se com facilidade a patela, sulco e bordas trocleares, côndilos medial e lateral do fêmur, e tendão do músculo extensor longo dos dedos. Após a remoção da maior parte do coxim gorduroso infrapatelar com emprego do "shaver" foram visibilizados, ainda com dificuldade, os ligamentos cruzados e os meniscos. Para a identificação dos primeiros foram necessárias movimentos de flexão e extensão e para os meniscos manobras de varo e valgo. O grau de dificuldade foi inversamente proporcional ao tamanho da articulação. Sendo assim, foi possível concluir que os portais artroscópicos utilizados possibilitaram a identificação das principais estruturas articulares, independente da idade, e o método em si teve por vantagem a rápida recuperação pós-operatória dos animais.The aim of this study was to evaluate arthroscopically the stifle joint of healthy Santa Ines sheep with different ages, and observe the joint elements according to the established portals. Eighteen Santa Ines sheep were divided into 3 equal groups according to the chronological age: GI - 6 to 8 months old (mean weight 25 kg, G II - 2 years old (mean weight 50 kg, and G III - 3.5 to 5 years old (mean weight 55 kg. Three arthroscopic portals were established: craniolateral primary arthroscopic portal, drainage outflow portal, and craniomedial instrumental portal. The patella, the trochlear groove and ridges, the medial and lateral femoral condyles, and the long digital extensor tendon were easily identified. After removing a great portion of the infrapatellar fat pad using a shaver, the cruciate ligaments and the menisci could be observed, even though with some difficulty. The limbs were flexed and extended to identify the cruciate ligaments. Varus and valgus stress of the joint was used to improve meniscal observation. The difficulty level was inversely proportional to the joint size. In conclusion, the arthroscopic portals allowed identification of the main elements of the knee joint, regardless of animal age, and the arthroscopic method had as advantage early postoperative recovery of the animals.

    Arthroscopic techniques for the hip joint have evolved into endoscopic methods for extra-articular disorders. These endoscopic strategies provide a less invasive alternative to open procedures for traditionally recognized forms of pathology. Endoscopy has defined new disorders amenable to surgical correction and has redefined some of these existing disorders. The peritrochanteric and deep gluteal regions represent 2 of the most currently active areas of exploration. Peritrochanteric problems include trochanteric bursitis, full-thickness and partial-thickness tears of the abductors including the gluteus medius and minimus, and external coxa saltans (snapping iliotibial band). Deep gluteal disorders include piriformis syndrome, and other variations of deep gluteal syndrome, and ischiofemoral impingement. Each of these evolving areas is highlighted in this chapter.

    Seven consecutive patients undergoing arthroscopic surgery in a gravity-fed fluid delivery system were studied. The average minimum adequate intraarticular pressure (MAIP) was 55 mm Hg. The height of a saline bag above the knee necessary to achieve this average MAIP was 75 cm. There was a positive correlation between diastolic blood pressure and the minimum adequate intraarticular pressure in this study. There was no positive correlation between systolic blood pressure and the MAIP. PMID:1418206

    Passive haptics, also known as tactile augmentation, denotes the use of a physical counterpart to a virtual environment to provide tactile feedback. Employing passive haptics can result in more realistic touch sensations than those from active force feedback, especially for rigid contacts. However, changes in the virtual environment would necessitate modifications of the physical counterparts. In recent work space warping has been proposed as one solution to overcome this limitation. In this technique virtual space is distorted such that a variety of virtual models can be mapped onto one single physical object. In this paper, we propose as an extension adaptive space warping; we show how this technique can be employed in a mixed-reality surgical training simulator in order to map different virtual patients onto one physical anatomical model. We developed methods to warp different organ geometries onto one physical mock-up, to handle different mechanical behaviors of the virtual patients, and to allow interactive modifications of the virtual structures, while the physical counterparts remain unchanged. Various practical examples underline the wide applicability of our approach. To the best of our knowledge this is the first practical usage of such a technique in the specific context of interactive medical training.

  3. Biomechanics of the Hip Capsule and Capsule Management Strategies in Hip Arthroscopy.

    2015-12-01

    Recent advances in our understanding of the function of the hip capsule have clarified its importance to normal hip function and kinematics. The iliofemoral ligament is the primary stabilizing structure for controlling anterior translation and external rotation of the hip, and is violated by the arthroscopic interportal capsulotomy. Microinstability of the hip occurring after surgical trauma remains a poorly defined clinical entity. In certain at-risk populations, capsular repair should be considered as part of an arthroscopic hip procedure to achieve optimal outcomes and avoid iatrogenic instability (dislocation or microinstability). Despite a lack of conclusive evidence-based indications, we recommend capsular repair in the settings of borderline hip dysplasia (or dysplastic variants such as increased femoral anteversion), hip hypermobility, connective tissue disorders, and traumatic or atraumatic instability. With careful attention to arthroscopic capsular management, adequate exposure can be achieved and reproducibly allow for an effective capsular repair when indicated. PMID:26524549

    Full Text Available Background: Shivering, the rate of which in regional anesthesia is 39% is an undesired complication seen postoperatively. Aims: This study aims to compare the ability of preventing the shivering of preemptive tramadol and dexmedetomidine during the spinal anesthesia (SA. Methods: A total of 90 patients with American Society of Anesthesiologists physical status I-II, aged 18-60 years and undergoing elective arthroscopic surgery with SA were divided into three groups randomly. After spinal block, 100 mg tramadol in 100 ml saline was applied in group T- (n = 30 and 0.5 μg/kg dexmedetomidine in 100 ml saline was applied in group D- (n = 30 and 100 ml saline was administered in group P- (n = 30 in 10 min. The hemodynamics, oxygen saturation, tympanic temperature, shivering and sedation scores were evaluated and recorded intraoperatively and 45 min after a postoperative period. Results: In group T and D, shivering scores were significantly lower when compared with group P in the intraoperative 20 th min (P = 0.01. Sedation scores in group D were significantly higher than the baseline values (P = 0.03 and values in group T and P (P = 0.04. Conclusions: Preemptive tramadol and dexmedetomidine are effective in preventing the shivering under SA. In addition, dexmedetomidine was superior in increasing the level of sedation which is sufficient to prevent the anxiety without any adverse effects.

    Interscalene brachial plexus anesthesia is commonly used for outpatient arthroscopic shoulder procedures. Ultrasound guidance has helped to minimize the cardiac, neurologic, and pulmonary complications associated with this block. Although rarely reported, pneumothorax may occur as a result of direct lung injury and even in a delayed fashion. We present a case of tension pneumothorax in a patient undergoing arthroscopic rotator cuff repair under both interscalene regional and general anesthesia. Surgeons and anesthesiologists must remain aware that ultrasound-guided interscalene blocks may be associated with pneumothorax and must initiate treatment expeditiously.

    2015-12-01

    Improved battlefield survival rates have resulted in a significant number of young active patients with lower-extremity amputations. Because of the increased demands placed on their hips, patients with amputations may be more susceptible to the sequelae of hip pathology and femoroacetabular impingement. Arthroscopic management of hip pathology may be successfully performed in patients with ipsilateral, contralateral, or bilateral lower-extremity amputations. We describe our experience in this unique patient population. A technique for secure patient positioning that provides sufficient countertraction in the case of contralateral amputation is described, as is the use of skeletal traction with a temporary external fixator for joint distraction in patients with ipsilateral amputations. Considerations specific to patients with high transfemoral amputations are discussed as well. PMID:27284510

    A total of 20 consecutive patients with knee stiffness post total knee arthroplasty (TKA) underwent arthroscopic lysis of adhesions and manipulation plus indwelling epidural were evaluated retrospectively. Epidural catheters were placed preoperatively for an intended 6 weeks of postoperative analgesia to facilitate intensive physical therapy. The mean loss of knee extension immediately before incision was 13.5 ± 9.1 degrees (range, 0-35 degrees) and flexion was 77.65 ± 19.2 degrees (range, 45-125 degrees). At the 6-week and final (mean, 0.47 years) follow-up, the loss of extension was 1.5 ± 5.1 degrees (range, -10 to +7 degrees) and 5.4 ± 4.7 degrees (range, 0-15 degrees), respectively, and flexion was 99.7 ± 12.3 degrees (range, 75-120 degrees) and 98.5 ± 16.1 degrees (range, 75-130 degrees), respectively. Of the 20 patients, 2 missed their 6-week clinic visit. Improvements in motion immediately preoperative to 6-week and final follow-up were each significant (p < 0.01). At examination 6 weeks postoperatively, 94.4% of patients met the definition for clinical motion success and 70% maintained success at final follow-up. Visual analog scale improved significantly from 5.4 to 2.0 (p < 0.01) at 6 weeks postoperative in the 12 patients with this data recorded. On the basis of this data, use of tunneled epidurals with arthroscopic lysis of adhesions for arthrofibrosis after TKA is correlated with a high likelihood of functional success postoperatively as measured by range of motion improvement.

    Background There is limited literature investigating preoperative physical therapy (pre-op PT) treatment on pain intensity and disability after musculoskeletal surgery. The purposes of the present cohort study were to describe patient characteristics for those who had and did not have pre-op PT treatment and determine whether pre-op PT influenced the length of postoperative physical therapy (post-op PT) treatment (number of sessions) and 3-month and 6-month postsurgical outcomes, such as pain intensity and disability. Patients and methods A total of 124 patients (mean age =43 years, 81 males) with shoulder pain were observed before and after shoulder arthroscopic surgery. Demographic data, medical history, and validated self-report questionnaires were collected preoperatively and at 3 months and 6 months after surgery. Analysis of variance models were performed to identify differences across measures for patients who had pre-op PT treatment and those who did not and to examine outcome differences at 3 months and 6 months. Alpha was set at the 0.05 level for statistical significance. Results Males had less participation in pre-op PT than females (P=0.01). In contrast, age, pain intensity, disability, and pain-associated psychological factors did not differ between pre-op PT treatment groups (P>0.05). Subacromial bursectomies were more commonly performed in patients having pre-op PT treatment (P<0.05). Pre-op PT treatment did not influence length of post-op PT treatment and did not affect 3-month and 6-month pain intensity and disability outcomes. Differences in distribution of pre-op PT for males and females and subacromial bursectomy did not influence 3-month or 6-month postsurgical outcomes. Conclusion Receiving pre-op PT treatment did not influence post-op PT treatment or pain and disability outcomes at 3 months and 6 months. This prospective cohort study provides no evidence of benefit for pre-op PT on post-op PT treatment or postsurgical outcomes. Females or patients receiving certain surgical procedures are more likely to undergo pre-op PT treatment. However, these differences did not influence postoperative outcomes in this cohort.

    Conclusion: In patients undergoing shoulder arthroscopic surgery under general anesthesia, the BCP significantly decreases rScO2, with further slight decrease of rScO2 with dexmedetomidine and esmolol induced hypotension with no affection of postoperative cognitive function with both drugs. Dexmedetomidine and esmolol are safe drugs with better safety of dexmedetomidine over esmolol.

    Safe and effective arthroscopic surgery requires ambidextrous motor skills. The current study examined dominant versus non-dominant hand performance on a virtual reality serious game in a group of expert arthroscopic surgeons (n=15) compared to a group of orthopedic surgery residents (n=10). A virtual reality Tetris game was performed with the arthroscopic camera and arthroscope in one hand, using an arthroscopic grasping tool in the opposite hand to manipulate the virtual Tetris blocks onto the game grid. A second run was performed after swapping instruments between hands. The order of hand testing was randomized. There was no statistically significant difference in exercise time, grasper path length, or camera path length between the right and left hands of the expert surgeons. In contrast, there were statistically significant differences in all of these parameters between the two hands for the orthopedic surgery residents, with better performance when the grasping tool was used in the dominant hand. The findings of this study suggest that virtual reality games which incorporate progressive cognitive loading could be used to facilitate training, automation, and objective assessment of surgical motor skills.

    A 75-year-old man presented in shock secondary to septic arthritis of the knee. The patient, with a known history of knee osteoarthritis, was treated elsewhere for mechanical locking symptoms and effusion with arthroscopic debridement, and developed septic arthritis, which disseminated to the leg and foot after a tear in the capsule, and a ruptured pyogenic popliteal cyst. Open debridement of the knee joint, and drainage of the abscesses of the leg and foot, were performed. Antibiotic-loaded cement beads were left in the residual space. Debridement was repeated and cement beads removed after 4 days, and finally the infection was eradicated without any serious consequences for the patient. There is debate over arthroscopic intervention for osteoarthritic knees. The presence of a popliteal cyst, which is a rather common finding in the latter, could be related to a significant number of complications, such as septic arthritis.

    2016-04-01

    Anterior inferior tibial fibular ligament tenderness to palpation, a positive squeeze test, and a positive external rotation test correlate well with syndesmosis instability after high ankle sprain. However, it is still unknown whether subtle unstable high ankle sprains (grade IIB) could heal satisfactorily with nonoperative treatment and whether their recovery would be prolonged compared with operative treatment.

    Full Text Available Introduction: Artroscopy of the knee is a procedure that is frequently developed as a diagnostic and therapeutic means in patients who suffer among other diseases, from chronic sinuvitis, lesions of the meniscus and adherence . A great number of these patients receive medical assistance at the outpatient department of the orthopaedic department where the need of its use is assessed. It is a relatively short procedure that has few risks when it is performed with the appropriate technique. Objective: To show the use of intra articular Bupivacaine 0,25 % in the artroscopy of the knee. Method: Retrospective study carried out at the University Hospital ¨Dr. Gustavo Aldereguía Lima¨ from Cienfuegos province from September 2002 to February 2003. This study was developed with 20 patients who were initially assisted at the service of Orthopaedics in which a group of therapeutic procedures were decided. Bupivacaine 0,25 % together with Epinephrine 0,1 % in a dose of 0,1 ml were injected in the intra articular space in a volume of 20 ml distributed in 4 sections with 5 ml each. At the level of the section where the artroscope was inserted , 5 ml of Bupivacaine 0,25 % was applied Result: the age of the patient ranged 30 to 61 years of age with a media of 44,6 years and a standard deviation of 12,6 years. The introduction and application of the procedure throughout artroscopy was possible in al patients. Conclusion: Bupivacaine is a good local anaesthetic because of its slow action since the onset of application and its prolonged duration, and because of the intensity and the duration of the sensorial block that is superior to the motor block.

Es un proceder relativamente corto y con pocos riesgos cuando se realiza con la técnica adecuada. Objetivo : Demostrar el uso de la bupivacaína al 0,25 % intraarticular en la artroscopia de la rodilla. Métodos: Estudio prospectivo realizado en el Hospital ¨Dr. Gustavo Aldereguía Lima¨ de Cienfuegos en el período comprendido entre septiembre 02 y febrero del 03 a un grupo de 20 pacientes atendidos inicialmente por el Servicio de Ortopedia y luego por Anestesiología, decidiéndose en conjunto el proceder terapéutico. Se inyectó bupivacaína en el espacio intraarticular, a 0,25 % con epinefrina 0,1 ml al 0,1 %, en un volumen de 20 ml, distribuidos en 4 portales a razón de 5 ml en cada uno. A nivel del portal donde se introdujo el artroscopio, se aplicó 5 mil. de bupivacaína al 0,25 % Resultados: Las edades de los pacientes oscilaron entre 30 y 61 años con una media de 44,6 años y desviación estándar de 12.6 años. Fue posible la introducción y la realización de los procedimientos a través de la artroscopia en todos los pacientes. Conclusión : La bupivacaína resultó un agente anestésico local muy favorecedor, por su inicio de acción lento y una duración prolongada, la intensidad y duración del bloqueo sensorial superior a las del bloqueo motor.

    A prospective study was performed on 50 patients suffering from osteochondritis dissecans of the knee and ankle to define criteria for stability and fixation of osteochondral lesions. Morphological parameters in MRI (size, fragmentation, cartilage, interface) and conventional radiology (separation, fragmentation) were registered and compared with arthroscopical staging. MRI staging based on different types of interfaces was demonstrated on T{sub 1}- and T{sub 2}-weighted images. MRI could correctly predict a Grade 1 lesion in 50%, a Grade 2 lesion in 90%, a Grade 3 lesion on 0%, and a Grade 4 lesion in 79%. Stable lesions were differentiated from unstable lesions in 90%. Radiographic findings corresponded with arthroscopic staging in only 56% of the cases because fibrotic connection may guarantee stability in case of bony separation. (orig./MG) [Deutsch] In einer prospektiven Studie an 50 Patienten mit einer Osteochondrosis dissecans (OD) des Knie- und Sprunggelenkes sollten MRT-Kriterien zur Beurteilung der Stabilitaet bzw. Einbindung des osteochondralen Fragmentes bestimmt werden. Fuer jede Laesion wurden verschiedene morphologische Merkmale im MRT (Groesse, Sinterung, Vitalitaet, Knorpelbeschaffenheit, Grenzzone) und im konventionellen Roentgenbild (Separation, Sinterung) bestimmt und mit den entsprechenden arthroskopischen Stadien verglichen. Das MRT-Stadium wurde anhand der Morphologie der Grenzzone der OD im T{sub 1}- und T{sub 2}-gewichteten Bild definiert. Mit der MRT wurde das Stadium 1 in 50%, das Stadium 2 in 90%, das Stadium 3 in 0% und das Stadium 4 in 79% richtig vorhergesagt. Eine korrekte Einstufung in stabile und instabile Fragmente gelang in 90% der Faelle. Mit der konventionellen Radiologie war eine Uebereinstimmung mit den arthroskopischen Stadien nur in 56% zu erreichen, da auch nativradiologisch abgetrennt erscheinende Fragmente noch stabil mit dem Mausbett verbunden sein koennen.

    and the costs of this treatment strategy. MATERIAL AND METHODS: The records of 371 consecutive patients, who had a diagnostic knee arthroscopy performed under local analgesia, were reviewed retrospectively. The diagnosis made during the diagnostic arthroscopy (371 patients) and a later therapeutic operation...... was the strategy in which the diagnostic and therapeutic operations were performed together as an outpatient procedure. The relatively poor diagnostic precision of arthroscopy is surprising and should be kept in mind when patients continue to have unexplained complaints in the knee, despite a normal arthroscopy.......INTRODUCTION: Outpatient knee arthroscopy under local analgesia can be performed solely as a diagnostic procedure. The aim was to estimate the diagnostic precision of such arthroscopy as compared to the diagnosis made during a secondary therapeutic operation, and to describe the flow of patients...

    We evaluated the relationship between the intramedullary lesion on MRI and cartilage damage in patients associated with acute anterior cruciate ligament (ACL) rupture. Thirty-two cases documented by MRI and arthroscopy within one month from injury underwent ACL reconstruction using ST-G, and arthroscopy was performed again after surgery. The mean term between reconstruction and postoperative arthroscopy was twelve months. The cartilage damage on arthroscopy was compared with the intramedullary lesion on MRI. Cartilage damage was observed in 9 cases (28.1%) during the initial arthroscopy and in 16 cases (50.0%) during the second arthroscopy. Intramedullary lesion was detected in all 32 cases (total: 73 lesions) on MRI. Intramedullary lesion leading to cartilage damage was common in the geographic-type lateral femoral condyle. There was significant difference between the lateral meniscus tear and the cartilage damage of the lateral compartment. (author)

    Full Text Available The role of hip arthroscopy in the management of femoroacetabular impingement (FAI has been advancing rapidly. In this case report, we describe the use of hip arthroscopy to successfully treat a femoral neck osteochondroma that caused a symptomatic labral tear in a 37 year old woman. Hip arthroscopy offers several advantages to surgical dislocation of the hip in the management of intra articular pathology and FAI. Hip arthroscopy is minimally invasive without the significant trauma to hip musculature, is useful in treatment of labral tears generated by FAI, and can be used to resect small lesions on the femoral head.

    To explore prospectively the hypothesis that MRI of the acutely locked knee can alter surgical decision-making.Design and patients. The study group comprised patients with a clinical diagnosis of knee locking requiring arthroscopy. The decision to carry out arthroscopy was made by an experienced consultant orthopaedic surgeon specialising in trauma and recorded in the patient's notes prior to MRI. Preoperative MRI was carried out using a 1.5 T system. The management was altered from surgical to conservative treatment in 20 (48%) patients on the basis of the MR findings. Arthroscopy was limited to patients with an MR diagnosis of a mechanical block, usually a displaced meniscal tear or loose body. Both patient groups were followed clinically until symptoms resolved.Results. Forty-two patients were entered into the study. MRI identified a mechanical cause for locking in 22 patients (21 avulsion meniscal tears and 1 loose body). All were confirmed at arthroscopy. Twenty patients were changed from operative to non-operative treatment on the basis of the MRI findings. One patient in this group required a delayed arthroscopy for an impinging anterior cruciate ligament stump. The sensitivity/specificity/accuracy of MRI in identifying patients who require arthroscopy was therefore 96%/100%/98% respectively.Conclusion. MRI can successfully segregate patients with a clinical diagnosis of mechanical locking into those who have a true mechanical block and those who can be treated conservatively. MRI should precede arthroscopy in this clinical setting. (orig.)

    2016-01-01

    Management of posterior malleolus fractures continues to be controversial, with respect to both need for fixation and fixation methods. Fixation methods include an open posterior approach to the ankle as well as percutaneous reduction and fixation with or without arthroscopy for visualization of the articular surface. Plain radiographs are unreliable in identifying fracture pattern and intraoperative reduction, making arthroscopy a valuable adjunct to posterior malleolus fracture management. In this article, we report a case of tibialis posterior tendon entrapment within a posterior malleolus fracture, as identified by arthroscopy and managed with open reduction. Tibialis posterior tendon entrapment within a posterior malleolus has not been previously reported. Ankle arthroscopy for posterior malleolus fractures provides an opportunity to identify soft-tissue or tendinous entrapment, articular surface reduction, and articular cartilage injuries unlikely to be identified with fluoroscopy alone and should be considered in reduction and fixation of posterior malleolus fractures.

    Objective:To compare the short-term and long-term curative effects of two different operation modes on anterior cruciate ligament reconstruction. Methods: Lysholm scoring method was performed in the second month, third month and twelfth month respectively after operation to compare the two different operation methods of autologous hamstring-tendon-bone method and hamstring transplant method for anterior cruciate ligament reconstruction. Results: Knee joint score of anterior cruciate ligament reconstruction by hamstring was better than that of patellar tendon group in the second and third month after operation (P0. 05) ; operative incision of patellar tendon group was longer than that of hamstring group (P<0. 05). Conclusion:Both methods are the major operation modes for anterior cruciate ligament reconstruction at present, and hamstring reconstruction has advantages over patellar tendon reconstruction such as small incision and beautiful appearance, which is favorable for the early functional exercise of knee joint after operation as patients' suffering can be reduced. Compared with patellar tendon reconstruction method, operative wound is smaller and bone structure is less injured in hamstring reconstruction method. Therefore, hamstring reconstruction method is more suitable for anterior cruciate ligament reconstruction among teenagers; in addition, if medial collateral ligament and pes anserinus tendon etc. Were injured, and if medial articular structure was unsteady with anterior and posterior cruciate ligaments break at the same time, ligamenta cruci-ata reconstruction should be performed by patellar tendon.%目的:观察对比关节镜下自体腘绳肌腱和髌腱移植2种不同手术方式重建前交叉韧带的术后近、远期疗效.方法:在手术后第2、3、12个月采用Lysholm膝关节评分法分别进行评分,对2种术式进行比较,并对随访资料进行分析.结果:术后第2月、第3月Lysholm膝关节评分腘绳肌腱组为62.14±11.61、72.18±9.91,髌腱组为63.45±6.41、87.59±11.11,2组比较差异有统计学意义(P<0.05);第12月2组Lysholm评分髌腱组87.59±11.11,腘绳肌腱组86.37±10.76,两者比较差异无统计学意义(P>0.05);手术切口:髌腱组9.50±2.01cm,腘绳肌腱组2.52±1.09cm,2组比较差异有统计学意义(P<0.05).结论:两者均为目前前交叉韧带重建的主要方法,但患者腘绳肌重建术切口小外观美观,而且术后更能减轻患者伤肢痛苦利于关节早期功能锻炼,腘绳肌重建由于手术创伤小于髌腱重建,且更少破坏骨性结构,更适合青少年前交叉韧带重建,但如果复合内侧副韧带、鹅足腱等损伤出现关节内侧结构不稳,前后交叉同时断裂我们主张采用髌腱重建韧带重建交叉韧带.

CONCLUSÕES: A freqüência da queixa estética foi de 35,1% na amostra. Pacientes masculinos; submetidos à tenotomia do CLB no lado dominante; com IMC abaixo de 30; com dobra cutânea abdominal abaixo de 23,2mm e dobra cutânea tricipital contralateral abaixo de 14,5mm são considerados de risco para apresentar queixa estética da deformidade residual.OBJECTIVE: To analyze the frequency of esthetic complaints after tenotomy of the long head of the biceps in order to create a criterion for some pre-operative analysis that could identify patients that tend to complain about esthetics after the procedure, and thus reduce the incidence. METHODS: A group of 89 patients (90 shoulders submitted to arthroscopic tenotomy of the long head of the biceps was analyzed. Patients included in the study had their bodily mass index (BMI measured and were classified into different degrees of obesity. The abdominal skin fold and the contralateral tricipital skin fold were measured with a millimeter-graded adipometer, and the biotype of each individual was determined by the angle measured in the xiphoid appendix. Tenotomy of the long head of the biceps, when indicated, was performed at its insertion in the upper labrum of the glenoid. Patients were asked about their perception of residual deformity created by the tenotomy of the long head of the biceps. Variables studied were age, gender, operated side, dominance, biotype, degree of obesity, abdominal skin fold, and contralateral tricipital skin fold. 77 patients were evaluated for a mean 15.14 (± 10.7 months period after the surgery. RESULTS: 50 patients (64.9% did not complain about deformity, whereas 27 patients (35.1% had some esthetic complaint. Statistical analysis was not significant in the cross analysis for age (P = 0.788, the side (P = 0.075, and the biotype (P = 0.529 of the patients who did present an esthetic complaint about their residual deformity. Significant correlation of deformity complaint was present in the evaluation of gender (p = 0.004, dominance (P = 0.026, and when a group was formed of patients with BMI below 30 (normal and overweight and this group was compared to patients with BMI above 30 (obesity grade one, two, and morbid (P = 0.005.

  12. Degenerative joint disease on MRI and physical activity: a clinical study of the knee joint in 320 patients

    International Nuclear Information System (INIS)

    We examined 320 patients with MRI and arthroscopy after an acute trauma to evaluate MRI in diagnosis of degenerative joint disease of the knee in relation to sports activity and clinical data. Lesions of cartilage and menisci on MRI were registered by two radiologists in consensus without knowledge of arthroscopy. Arthroscopy demonstrated grade-1 to grade-4 lesions of cartilage on 729 of 1920 joint surfaces of 320 knees, and MRI diagnosed 14 % of grade-1, 32 % of grade-2, 94 % of grade-3, and 100 % of grade-4 lesions. Arthroscopy explored 1280 meniscal areas and showed degenerations in 10 %, tears in 11.4 %, and complex lesions in 9.2 %. Magnetic resonance imaging was in agreement with arthroscopy in 81 % showing more degenerations but less tears of menisci than arthroscopy. Using a global system for grading the total damage of the knee joint into none, mild, moderate, or severe changes, agreement between arthroscopy and MRI was found in 82 %. Magnetic resonance imaging and arthroscopy showed coherently that degree of degenerative joint changes was significantly correlated to patient age or previous knee trauma. Patients over 40 years had moderate to severe changes on MRI in 45 % and patients under 30 years in only 22 %. Knee joints with a history of trauma without complete structural or functional reconstitution showed marked changes on MRI in 57 %, whereas stable joints without such alterations had degenerative changes in only 26 %. There was no correlation of degenerative disease to gender, weight, type, frequency, and intensity of sports activity. Therefore, MRI is an effective non-invasive imaging method for exact localization and quantification of chronic joint changes of cartilage and menisci that recommends MRI for monitoring in sports medicine.

    Arthroscopy enables direct inspection of the articular surface, but provides no information on deeper cartilage layers. Optical coherence tomography (OCT), based on measurement of reflection and backscattering of light, is a diagnostic technique used in cardiovascular surgery and ophthalmology. It provides cross-sectional images at resolutions comparable to that of low-power microscopy. The aim of this study was to determine if OCT is feasible for advanced clinical assessment of lesions in equine articular cartilage during diagnostic arthroscopy. Diagnostic arthroscopy of 36 metacarpophalangeal joints was carried out ex vivo. Of these, 18 joints with varying degrees of cartilage damage were selected, wherein OCT arthroscopy was conducted using an OCT catheter (diameter 0.9 mm) inserted through standard instrument portals. Five sites of interest, occasionally supplemented with other locations where defects were encountered, were arthroscopically graded according to the International Cartilage Repair Society (ICRS) classification system. The same sites were evaluated qualitatively (ICRS classification and morphological description of the lesions) and quantitatively (measurement of cartilage thickness) on OCT images. OCT provided high resolution images of cartilage enabling determination of cartilage thickness. Comparing ICRS grades determined by both arthroscopy and OCT revealed poor agreement. Furthermore, OCT visualised a spectrum of lesions, including cavitation, fibrillation, superficial and deep clefts, erosion, ulceration and fragmentation. In addition, with OCT the arthroscopically inaccessible area between the dorsal MC3 and P1 was reachable in some cases. Arthroscopically-guided OCT provided more detailed and quantitative information on the morphology of articular cartilage lesions than conventional arthroscopy. OCT could therefore improve the diagnostic value of arthroscopy in equine orthopaedic surgery. PMID:23810744

  20. USG AND MRI CORRELATION IN THE EVALUATION OF MENISCAL LESIONS OF KNEE

    Full Text Available AIMS AND OBJECTIVE: The objective of this study was to evaluate the role of a handheld USG of 7-13 MHz in evaluating meniscal lesions of knee and comparing it to the results obtained with magnetic resonance imaging. MATERIAL AND METHODS: A comparative double blind study was done between ultrasonography and MRI of fifty patients with a history of knee trauma or with suspected knee meniscal lesions, who were referred to the department of Radiodiagnosis. MRI and USG results were finally correlated with arthroscopy findings. All these patients had a significant history and clinical evaluation suggested meniscal lesion of the knee joint. Cases which have been operated previously on the same knee were excluded from this study. RESULTS: Out of the 50 patients, a total of 100 menisci were examined, out of which after final arthroscopy confirmation, 34 had meniscal tears, 3 degenerative tears, and two patients had meniscal cysts both of which were not associated with a tear of the meniscus. CONCLUSION: The specificity of USG matched that of MRI and it can reasonably be applied to confirm the clinical diagnosis before undertaking arthroscopy. However, the lower sensitivity suggests that there is still a need to improve the technique to reduce the number of false-negative diagnoses and thus to avoid unnecessary arthroscopy. USG may be used as a screening tool prior to arthroscopy in selected cases where MRI is a contraindication or is not available or if the patient is not affording.

    Evaluation of articular cartilage and subchondral bone is essential in the diagnosis of joint diseases and injuries. Interobserver and intraobserver reproducibilities of arthroscopic grading are only poor to moderate. Thus, for quantitative and objective evaluation of cartilage and subchondral bone, ultrasound arthroscopy (UA) has been introduced to clarify this dilemma. Assessment of the clinical feasibility of high-frequency ultrasonography (US) during 6 knee arthroscopies was conducted, and the surgical technique is presented. US imaging was conducted with a flexible 9-MHz US catheter inserted into the joint through conventional portals. US and arthroscopy videos were synchronously recorded, and US parameters for cartilage and subchondral bone characteristics were measured. Arthroscopy and US imaging were combined to perform cartilage grading. UA produced quantitative data on lesion size, as well as cartilage quality, and showed subchondral bone changes. Visualization of an osteochondritis dissecans lesion not detected by conventional arthroscopy and US-guided retrograde drilling were possible with UA. To conclude, UA proved to be clinically feasible and aided in the diagnosis when assessing knee osteochondral lesions. PMID:26697300

    Purpose: To evaluate the diagnostic efficacy of using additional oblique coronal 1 mm proton density-weighted (PDW) MR imaging of the knee for detection and grading anterior cruciate ligament (ACL), anteromedial bundle (AMB) and posterolateral bundle (PLB) injuries. Materials and methods: We prospectively assessed preoperative MR images of 50 patients (36 men, 14 women; age range, 18–62 years). First, we compared the diagnostic performance of routine sagittal (3 mm) and additional oblique coronal images (1 mm) for ACL tears. Then, we compared the tear types (AMB or PLB) and grade presumed from oblique coronal MR imaging with arthroscopy. Results: Arthroscopy revealed ACL tear in 24 (48%) patients. There was significant difference between sagittal images and arthroscopy results for ACL tear recognition (p < 0.001). No significant difference was detected for oblique coronal images when compared with arthroscopy results (p = 0.180). Sensitivity and specificity values for ACL tear diagnosis were 37.04% and 95.65% for sagittal images; 74.07% and 91.30% for oblique coronal images. There was no significant difference between arthroscopy and oblique coronal MR images in grading AMB and PLB injuries (p > 0.05). Conclusion: Addition of thin slice oblique coronal images to conventional sequences could better contribute to better verifying the presence of ACL tear and in determining its grade.

    Recent advances in hip arthroscopy offer an approach for treating an uncommon but highly disabling injury from intra-articular missile injury to the hip. Hip arthroscopy affords the patient the benefit of minimally invasive surgery while allowing for the diagnosis and treatment of concomitant pathology, which may be either acute, from the trauma of the missile, or chronic. We present a technique for the removal of projectiles from the central and peripheral compartments of the hip joint. Through a surgical series of a variety of gunshot wounds, we detail the unique aspects of retrieval for the various missile endpoints. We describe this technique for bullets or pieces of bullets lodged within the hip joint space, bone of the acetabulum, or femoral head. Furthermore, we provide an example in which hip arthroscopy is not a suitable option for treatment because of the resulting fracture pattern, which necessitates open reduction along with internal fixation.

    Purpose: Arthroscopic skills training outside the operative room may decrease risks and errors by trainee surgeons. There is a need of simple objective method for evaluating proficiency and skill of arthroscopy trainees using simple bench model of arthroscopic simulator. The aim of this study is to correlate motor task performance to level of prior arthroscopic experience and establish benchmarks for training modules. Methods: Twenty orthopaedic surgeons performed a set of tasks to assess a) arthroscopic triangulation, b) navigation, c) object handling and d) meniscus trimming using SAWBONES “FAST” arthroscopy skills workstation. Time to completion and the errors were computed. The subjects were divided into four levels; “Novice”, “Beginner”, “Intermediate” and “Advanced” based on previous arthroscopy experience, for analyses of performance. Results: The task performance under transparent dome was not related to experience of the surgeon unlike opaque dome, highlighting the importance of hand-eye co-ordination required in arthroscopy. Median time to completion for each task improved as the level of experience increased and this was found to be statistically significant (p 85%) of subjects across all the levels reported improvement in performance with sequential tasks. Conclusion: Use of the arthroscope requires visuo-spatial coordination which is a skill that develops with practice. This simple box model can reliably differentiate the arthroscopic skills based on experience and can be used to monitor progression of skills of trainees in institutions. PMID:27801643

    In suspected chondropathia patellae, CT after intraarticular contrast injection considerably facilitates the preoperative diagnosis. This technique is less costly and laborious than arthroscopy and has a high level of reliability. Before taking surgical measures, the clinical symptoms and the extent of cartilage degeneration must be known.

  14. The value of water-excitation 3D FLASH and fat-saturated PDw TSE MR imaging for detecting and grading articular cartilage lesions of the knee

    International Nuclear Information System (INIS)

    To evaluate the diagnostic accuracy of water-excitation (WE) 3D FLASH and fat-saturated (FS) proton density-weighted (PDw) TSE MR imaging for detecting, grading, and sizing articular cartilage lesions of the knee. A total of 26 patients underwent MR imaging prior to arthroscopy with the following sequences: (1) WE 3D FLASH: 28/11 ms, scan time: 4 min 58 s, flip angle: 40 ; (2) FS PDw TSE: 3433/15 ms, scan time: 6 min 15 s, flip angle: 180 . Grade and size of the detected lesions were quantified and compared with the results of arthroscopy for each compartment. The sensitivity, specificity, positive and negative predictive values, and accuracy for detecting cartilage lesions were 46%, 92%, 81%, 71% and 74% for WE 3D FLASH and 91%, 98%, 96%, 94% and 95% for FS PDw TSE MR imaging. WE 3D FLASH correlated significantly with arthroscopy for grading on the patella (P<0.0001) and the femoral trochlea (P=0.02) and for sizing on the femoral trochlea (P=0.03). FS PDw correlated significantly (P<0.0001) with arthroscopy for grading and sizing on all compartments. FS PDw TSE is an accurate method for detecting, grading and sizing articular cartilage lesions of the knee and yielded superior results relative to WE 3D FLASH MR imaging. (orig.)

    To investigate the accuracy of conventional magnetic resonance imaging (MRI) in determining the severity of glenoid bone loss in patients with anterior shoulder dislocation by comparing the results with arthroscopic measurements. Institutional review board approval and written consent from all patients were obtained. Thirty-six consecutive patients (29 men, seven women; mean age, 34.5 [range, 18-55] years) with recurrent anterior shoulder dislocation (≥3 dislocations; mean, 37.9; range, 3-200) and suspected glenoid bone loss underwent shoulder MRI before arthroscopy (mean interval, 28.5 [range, 9-73] days). Assessments of glenoid bone loss by MRI (using the best-fit circle area method) and arthroscopy were compared. Inter- and intrareader reproducibility of MRI-derived measurements was evaluated using arthroscopy as a comparative standard. Glenoid bone loss was evident on MRI and during arthroscopy in all patients. Inter- and intrareader correlations of MRI-derived measurements were excellent (intraclass correlation coefficient = 0.80-0.82; r = 0.81-0.86). The first and second observers' measurements showed strong (r = 0.76) and moderate (r = 0.69) interreader correlation, respectively, with arthroscopic measurements. Conventional MRI can be used to measure glenoid bone loss, particularly when employed by an experienced musculoskeletal radiologist. (orig.)

    The purpose of this study was to assess the usefulness of MRI in the evaluation of autografts after anterior cruciate ligament reconstruction. The subjects were 110 patients with anterior cruciate ligament reconstruction using patellar tendon autografts who underwent clinical examination, MRI, and arthroscopy of the knee. T1- and T2-weighted MR images were obtained in sagittal plane. Clinical findings were categorized into three groups: normal, borderline, and abnormal. The MRI appearances of the autografts were categorized into three types: straight continuous band (type I), interrupted band (type II) and generalized increased intensity band (type III). The clinical findings and MRI findings were compared with arthroscopic findings. Ninety-six percent of the type I showed no autograft tear on arthroscopy. In comparison with the clinical findings, MRI was found to be well correlated with arthroscopic findings. In conclusion, if the clinical findings are normal, patients are to be followed-up without MRI and arthroscopy. However, if clinical findings are either borderline or abnormal, MRI should be performed prior to arthroscopy. (author)

  6. Accuracy of 3-Tesla MR and MR arthrography in diagnosis of meniscal retear in the post-operative knee

    International Nuclear Information System (INIS)

    This study assesses the accuracy of 3-Tesla (3-T) conventional MR imaging, 3-T MR arthrography, and the combined use of conventional MR and MR arthrography in the diagnosis of meniscal retears as compared with arthroscopy. The study also assess whether there are false-negative cases in which injected contrast does not extend into the meniscus despite a meniscal retear being seen on arthroscopy. One hundred consecutive knee MR arthrograms performed on patients with previous knee surgery were reviewed retrospectively. 3-T conventional MR imaging, 3-T MR arthrography, and the combined use of conventional MR and MR arthrography were assessed for meniscal retears as compared with arthroscopy. The criterion used to diagnose a meniscal retear on MR arthrogram was injected contrast tracking into the meniscus. All patients underwent second-look arthroscopy. Seventy-four patients had conventional MR findings consistent with a meniscal retear. In 83 of the 100 patients, intraarticular contrast helped in demonstrating a retear. In ten patients, there were MR findings consistent with a meniscal retear despite intra-articular contrast not tracking into the meniscus. Ninety-four of the 100 patients had meniscal retears on second-look arthroscopy. Three-Tesla conventional MR examination was 78 % sensitive and 75 % specific, MR arthrogram examination was 88 % sensitive and 100 % specific, and the combined use of MR and MR arthrogram imaging was 98 % sensitive and 75 % specific in the diagnosis of a meniscal retear. The combined use of 3-T MR and MR arthrography allows for high sensitivity and specificity in meniscal retear detection. In some patients, intraarticular contrast will not track into a meniscal retear. When MR findings are consistent with a meniscal retear but contrast does not extend into the meniscus, a meniscal retear is likely. (orig.)

    1988-01-01

    Purely clinical examination of the knee joint can, at best, only be regarded as a "screening procedure". Diagnosis with the aid of apparatus (sonography, arthrography, CT, NMR) produces better results. However, arthroscopy performed by an experienced examiner confirms the diagnosis in cases of suspected meniscus injury or isolated lesions of the cruciate ligaments and leads to early and therefore optimal therapy. In a retrospective study 300 arthroscopies performed in 1985 were selected and evaluated. In 1986/87, a further 300 patients were clinically examined prospectively, according to the same criteria, and findings were compared with the arthroscopy performed the following day. Clinically, in 287 patients with multiple diagnoses, internal meniscus lesions were diagnosed in 162 cases (54%), external meniscus lesions in 38 (13%), chondropathia patellae in 54 (18%), and old ruptures of the cruciate ligaments in 46 (15%). In 13 patients no diagnosis could be established. Arthroscopically, pathology of the internal meniscus was found in 98 (33%) of the 300 patients, of the external meniscus in 40 (13%), cartilage damage in 103 (34%), old cruciate ligament ruptures in 51 (17%), and recent anterior cruciate ligament ruptures in 156 (52%); in 40 cases findings were normal. At 78%, the highest positive predictive value (proportion of tentative clinical diagnoses confirmed by arthroscopy) was found in cases of old ruptures of the anterior cruciate ligament, followed by external meniscus lesions (61%) and internal meniscus lesions (55%); i.e., only 55 out of 100 clinically suspected internal meniscus lesions are diagnosed by arthroscopy.(ABSTRACT TRUNCATED AT 250 WORDS)

  8. Imaging of postarthroscopic complications after knee injuries

    International Nuclear Information System (INIS)

    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.

  9. Arthroscopic anatomy of the subdeltoid space

    2013-09-01

    Full Text Available From the first shoulder arthroscopy performed on a cadaver in 1931, shoulder arthroscopy has grown tremendously in its ability to diagnose and treat pathologic conditions about the shoulder. Despite improvements in arthroscopic techniques and instrumentation, it is only recently that arthroscopists have begun to explore precise anatomical structures within the subdeltoid space. By way of a thorough bursectomy of the subdeltoid region, meticulous hemostasis, and the reciprocal use of posterior and lateral viewing portals, one can identify a myriad of pertinent ligamentous, musculotendinous, osseous, and neurovascular structures. For the purposes of this review, the subdeltoid space has been compartmentalized into lateral, medial, anterior, and posterior regions. Being able to identify pertinent structures in the subdeltoid space will provide shoulder arthroscopists with the requisite foundation in core anatomy that will be required for challenging procedures such as arthroscopic subscapularis mobilization and repair, biceps tenodesis, subcoracoid decompression, suprascapular nerve decompression, quadrangular space decompression and repair of massive rotator cuff tears.

    The purpose of this study was to clarify the efficacy of stress radiography (stress X-P), ultrasonography (US), and magnetic resonance (MR) imaging in the detection of the anterior talofibular ligament (ATFL) injury. Thirty-four patients with ankle sprain were involved. In all patients, Stress X-P, US, MR imaging, and arthroscopy were performed. The arthroscopic results were considered to be the gold standard. The imaging results were compared with the arthroscopic results, and the accuracy calculated. Arthroscopic findings showed ATFL injury in 30 out of 34 cases. The diagnosis of ATFL injury with stress X-P, US, MR imaging were made with an accuracy of 67, 91 and 97%. US and MR imaging demonstrated the same location of the injury as arthroscopy in 63 and 93%. We have clarified the diagnostic value of stress X-P, US, and MR imaging in diagnosis of ATFL injury. We obtained satisfactory results with US and MR imaging. (orig.)

    International Nuclear Information System (INIS)

    Objective. To develop a new method of magnetic resonance arthrography (MRA) of the knee using an anterior approach analogous to the portals used for knee arthroscopy.Design. An anterior approach to the knee joint was devised mimicking anterior portals used for knee arthroscopy. Seven patients scheduled for routine knee MRA were placed in a decubitus position and under fluoroscopic guidance a needle was advanced from a position adjacent to the patellar tendon into the knee joint. After confirmation of the needle tip location, a dilute gadolinium solution was injected.Results and conclusion. All the arthrograms were technically successful. The anterior approach to knee MRA has greater technical ease than the traditional approach with little patient discomfort. (orig.)

    Meniscal cysts are a rare disease constantly combined with a horizontal meniscal lesion. Currently, nuclear magnetic resonance (MRI) is the main diagnostic tool, because of its high sensitivity and specificity, and decompression arthroscopy combined with selective meniscectomy is the treatment of choice. The Authors report a case of a voluminous medial meniscal cyst where instrumental examination, MRI, was fundamental for the preoperative diagnosis of the horizontal meniscal lesion causing the cystic degeneration of the meniscus. The treatment performed was selective meniscectomy of the body and posterior horn of the medial meniscus and decompression of the voluminous cyst by arthroscopy. Physical examination after six months showed the complete resolution of swelling at the medial hemirima, no walking pain and normal range of motion.

    Femoroacetabular impingement (FAI is a condition characterized by the impingement of the femur and acetabulum. In Japan, this disorder has become recognized gradually. Here we report a rare case of surgically treated FAI, associated with an osseous protrusion on the acetabulum of a 30-year-old female. Plain computed tomography (CT and reconstructive 3D-CT images clearly demonstrated an anterolateral bony protrusion. Hip arthroscopy showed no degeneration of the cartilage on either the femoral or acetabular side, but degeneration at the edge of labrum was observed in the region of the bony protrusion. The complete removal of the bony protrusion under hip arthroscopy was thus considered impracticable, and a small skin incision was therefore made anteriorly to approach the acetabulum. The Short-Form 36-Item Health Survey (SF-36 revealed improvement in all scores.

    We present a case of intraarticular myositis ossificans in the right knee of a child. Myositis ossificans (MO), though relatively rare in childhood and even more uncommon within a joint, should be included in the differential diagnosis of an intra-articular mass when indicated by the typical clinical, radiographic, and histologic findings. An 11-year-old male presented with a history of trauma to his right knee. Four weeks after the initial injury, an MRI demonstrated evidence of an ACL rupture with a ''cystic mass'' within the intercondylar notch along the anterior surface of the torn ligament. At subsequent arthroscopy, the mass noted on MRI was removed. The histology was consistent with MO. The authors believe this to be the first case of MO in the intercondylar notch detected by MRI, treated by arthroscopy, and confirmed by histology. (orig.)

  17. Radiographer led supplementary anterior cruciate ligament MRI sequences: Technical report

    International Nuclear Information System (INIS)

    Aims: To compare different supplementary MRI sequences of the ACL to arthroscopy and determine the diagnostic performance of each sequence. To ascertain whether radiographers could identify patients requiring supplementary MRI sequences of anterior cruciate ligament (ACL) tears, without a supervising radiologist. Methods: The study had ethical approval and two hundred and thirty one consecutive prospective MRI patients with mechanical knee symptoms (77 females, 154 males, of mean age 43.5, range 18–82 years) gave written informed consent. They then had a knee arthroscopy within seven days of the MRI. This was a pragmatic study to see if the six general MRI radiographers, each with over four years experience, could evaluate the ACL on routine orthogonal sequences (sagittal T1, Gradient Echo T2, Coronal STIR and axial fat suppressed dual echo). If they identified no ACL, then two 3D volume sequences (Dual Echo Steady State and Fast Low Angle Shot) and 2D limited sagittal oblique T1 sequences were also performed. Patients requiring extra sequences, missed by the radiographers, were recalled. The MRI sequences were independently evaluated in a blinded fashion by two consultant radiologists and a specialist radiology registrar and compared to the subsequent knee arthroscopy, as the gold standard, to determine the diagnostic performance statistics. Results: The cohort was on the knee arthroscopy weighting list and comprised 205 patients with chronic, 20 acute and 6 acute on chronic mechanical knee symptoms. There were no posterior cruciate, medial, or lateral collateral ligament tears at arthroscopy, used as the gold standard. The arthroscopy was normal and the radiographers correctly did not scan the extra sequence in 140 patients (72%) who then had normal arthroscopies. The radiographers did perform additional ACL sequences in 63 patients (27%). Of these, 10 patients had a partial and 12 complete ACL tears. Only two patients (0.9%) were recalled for additional

    The complexity of the carpus explains the difficulty treating carpal injuries. Lesions are dominated by perilunate dislocation, scapholunate dislocation, and scaphoid fractures. The other injuries are trivial. Symptoms include pain and loss of wrist strength, reversible for an acute and well-treated lesion. Too often, these ligament injuries are diagnosed late. For delays longer than 6 weeks, ligament repair is ineffective. These old, complex lesions are potentially highly arthritic in the radiocarpal and mediocarpal joints. Improvements in wrist surgery have mitigated these chronic lesions. Various surgical techniques can preserve a functional wrist; wrist arthrodesis is no longer the only solution for these arthritic wrists. Over the past decade, arthroscopy has contributed to better understanding the injuries of the carpus as well as to better healing them. For acute or chronic ligament injuries without degenerative osteoarthritis, arthroscopy is the treatment of the future. This technique involves a long learning curve and the various arthroscopic techniques must be validated.

    Traditional arthroscopic examination is subjective and poorly reproducible. Recently, we introduced an arthroscopic ultrasound method for quantitative diagnostics of cartilage lesions. Here we describe our investigation of the feasibility of ultrasound arthroscopy for simultaneous measurements of articular cartilage and subchondral bone. Human osteochondral samples (n = 13) were imaged using a clinical 9-MHz ultrasound system. Ultrasound reflection coefficients (R, IRC), the ultrasound roughness index (URI) and the apparent integrated backscattering coefficient (AIB) were determined for both tissues. Mechanical testing, histologic analyses and micro-scale computed tomography imaging were the reference methods. Ultrasound arthroscopies were conducted on two patients. The ultrasound reflection coefficient correlated with the Mankin score and Young's modulus of cartilage (|r| > 0.56, p 0.70, p 0.59, p 0.65, p < 0.05). Arthroscopic ultrasound examination provided diagnostically valuable information on cartilage and subchondral bone in vivo. PMID:23743098

    Objective: To evaluate the efficacy of direct MR arthrography for diagnosing plica synovialis mediopatellaris (PSM). Material and Methods: Twenty-two knees of 19 patients were examined by direct MR arthrography. In 19 of those knees, field-echo T2*-weighted transaxial images were obtained with intra-articular administration of 40 ml of saline (direct MR arthrography). In the other 3 knees, T1-weighted transaxial images were obtained with intra-articular administration of 40 ml of gadopentetate dimeglumine. Conventional MR images were evaluated prior to direct MR arthrography in 12 of the 22 knees. The results of direct MR arthrography and conventional MR imaging were compared with the arthroscopic findings. Results: Direct MR arthrography demonstrated 17 of 19 PSMs proved on arthroscopy. The features of 16 PSMs on direct MR arthrography corresponded accurately with the arthroscopic classification. Conventional MR demonstrated only 3 plicae. Conclusion: Direct MR arthrography enabled accurate diagnosis of PSMs and could replace diagnostic arthroscopy.

    2006-06-15

    Objective: To clarify the role of MR-imaging in the diagnosis of anterior ankle impingement syndromes. Materials and methods: We prospectively examined 51 consecutive patients with chronic ankle pain by MR-imaging. Arthroscopy was performed in 29 patients who previously underwent non-enhanced MR-imaging; in 11 patients, indirect MR-arthrography additionally was performed. MR-examinations were correlated with clinical findings; MR and arthroscopy scores were statistically compared, agreement was measured. Results: Arthroscopy demonstrated granulation tissue in the lateral gutter (38%) and anterior recess (31%), lesions of the anterior tibiofibular (31%) and the anterior talofibular ligament (21%) as well as intraarticular bodies (10%). Stenosing tenosynovitis and a ganglionic cyst were revealed as extraarticular causes for chronic ankle pain by MR-examination (17%). Agreement of MR-imaging and arthroscopy was fair for the anterior talofibular ligament and the anterior joint cavity (kappa 0.40). Major discrepancy was found for non-enhanced MR scans (kappa 0.49) when compared with indirect MR-arthrography (kappa 0.03) in the anterior cavity. The sensitivity for lesions of the anterior talofibular and calcaneofibular ligament and the anterior cavity (0.91-0.87) detected by MR-imaging was superior in comparison to lesions of the anterior tibiofibular ligament and anteromedial cavity (0.50-0.24). Conclusion: MR-imaging provides additional information about the mechanics of chronic ankle impingement rather than an accurate diagnosis of this clinical entity. The method is helpful in differentiating extra- from intra-articular causes of ankle impingement. Indirect MR-arthrography has little or no additional value in patients with ankle impingement syndrome.

    McCarthy, Joseph C; Lee, Jo-Ann

    2004-12-01

    Advancement in diagnostic and therapeutic applications for hip arthroscopy have dispelled previous myths about early hip disease. Arthroscopic findings have established the following facts: Acetabular labral tears do occur; acetabular chondral lesions do exist; tears are most frequently anterior and often associated with sudden twisting or pivoting motions; and labral tears often occur in association with articular cartilage lesions of the adjacent acetabulum or femoral head, and if present for years, contribute to the progression of delamination process of the chondral cartilage. Magnetic resonance arthrography represents an improvement over conventional magnetic resonance imaging, it does have limitations when compared with direct observation. Although indications for hip arthroscopy are constantly expanding, the most common indications include: labral tears, loose bodies, chondral flap lesions of the acetabular or femoral head, synovial chondromatosis, foreign body removal, and crystalline hip arthropathy (gout, pseudogout, and others). Contraindications include conditions that limit the potential for hip distraction such as joint ankylosis, dense heterotopic bone formation, considerable protrusio, or morbid obesity. Complication rates have been reported between 0.5 and 5%, most often related to distraction and include sciatic or femoral nerve palsy, avascular necrosis, and compartment syndrome. Transient peroneal or pudendal nerve effects and chondral scuffing have been associated with difficult or prolonged distraction. Meticulous consideration to patient positioning, distraction time and portal placement are essential. Judicious patient selection and diagnostic expertise are critical to successful outcomes. Candidates for hip arthroscopy should include only those patients with mechanical symptoms (catching, locking, or buckling) that have failed to respond to conservative therapy. The extent of articular cartilage involvement has the most direct relationship

  5. Standard sonography and arthrosonography in the study of rotator cuff tears

    International Nuclear Information System (INIS)

    Purpose. The aim of this study was to evaluate the sensitivity of ultrasonography, integrating standard ultrasound and arthrosonography after injecting a saline solution into the glenohumeral cavity in cases of suspected rotator cuff tears. Materials and methods. We respectively examinated 40 patients awaiting shoulder arthroscopy for suspected or diagnosed tears of the rotator cuff. A radiologist, unaware of the pre-operative diagnosis, performed an ultrasound scan on all the patients before and after the injection of saline solution into the glenohumeral cavity. The parameters considered were presence or absence of a rotator cuff injury; type of injury according to Snyder and its extent along the longitudinal and transverse planes; presence or absence of effusion into the articular cavity; subacromial/subdeltoid bursal distension. All the patients underwent arthroscopy either the same day of the day after the ultrasound examination. Results. Standard sonography showed 26 complete rotator cuff tears (type C according to Snyder), 2 partial tears (type B according to Snyder) and 12 intact rotator cuffs. Arthrosonography detected 31 complete rotator cuff tears (type C according to Snyder), 1 partial tear (type B according to Snyder) and 8 intact rotator cuffs. Arthroscopy identified 32 complete rotator cuff tears (type C according to Snyder), 1 partial tear (type B according to Snyder) and 8 intact rotator cuffs. Analysis of the results shows that, taking arthroscopy as the gold standard, the sensitivity of normal sonography is 81.2%, whereas that of arthosonography is 96.8% (p<0.05). Conclusions. On the basis of the data obtained in this study, standard sonography , integrated with the injection of a saline solution into the glenohumeral cavity, considerably increases the diagnostic sensitivity for rotator cuff tears. The authors suggest that arthrosonography can be used in the event of suspected rotator tears, when MRI is contraindicated

    2011-09-01

    Full Text Available Abstract Background The arthroscopic findings in patients with chronic anterior syndesmotic instability that need reconstructive surgery have never been described extensively. Methods In 12 patients the clinical suspicion of chronic instability of the syndesmosis was confirmed during arthroscopy of the ankle. All findings during the arthroscopy were scored. Anatomical reconstruction of the anterior tibiofibular syndesmosis was performed in all patients. The AOFAS score was assessed to evaluate the result of the reconstruction. At an average of 43 months after the reconstruction all patients were seen for follow-up. Results The syndesmosis being easily accessible for the 3 mm transverse end of probe which could be rotated around its longitudinal axis in all cases during arthroscopy of the ankle joint, confirmed the diagnosis. Cartilage damage was seen in 8 ankles, of which in 7 patients the damage was situated at the medial side of the ankle joint. The intraarticular part of anterior tibiofibular ligament was visibly damaged in 5 patients. Synovitis was seen in all but one ankle joint. After surgical reconstruction the AOFAS score improved from an average of 72 pre-operatively to 92 post-operatively. Conclusions To confirm the clinical suspicion, the final diagnosis of chronic instability of the anterior syndesmosis can be made during arthroscopy of the ankle. Cartilage damage to the medial side of the tibiotalar joint is often seen and might be the result of syndesmotic instability. Good results are achieved by anatomic reconstruction of the anterior syndesmosis, and all patients in this study would undergo the surgery again if necessary.

    Since the first knee arthroscopy in 1912, it is routine to scope all joints and many extra-articular structures. The effect of arthroscopic procedures in overuse conditions is sparsely documented and should be investigated in randomized studies, but score systems to evaluate clinical effects are ...... are lacking. An increased understanding of tissue reaction to loading and ligament healing as well as neuromuscular control is likely to change the basic principles of treatment and prevention in relation to sports injuries....

    The subscapularis tendon plays an essential role in shoulder function. Although subscapularis tendon tears are less common than other rotator cuff tears, tears of the subscapularis tendon have increasingly been recognized with the advent of magnetic resonance imaging and arthroscopy. A suture bridge technique for the treatment of posterosuperior rotator cuff tears has provided the opportunity to improve the pressurized contact area and mean footprint pressure. However, suture bridge fixation ...

    To evaluate the diagnostic ability of MR imaging for plica synoviallis mediopatellaris (PSM), we retrospectively reviewed the MR imaging findings of patellofemoral space in 20 knee joints of 11 patients. In all 20 knee joints, arthroscopy and MR imaging were available. MR imaging was performed with a 1.5 Tesla Magnetom (Siemens) using a round surface coil. Pulse sequences were SE (TR 600 ms/TE 26 ms), SE (TR 200 ms/TE 26,70 ms) and FLASH (TR 450 ms/TE 15 ms/FA 90deg). In six of the 20 knees with PSM proved by arthroscopy, a low intensity band was shown above the medial condyle of the femur on both T1- and T2-weighted MR images, and on FLASH images this band was shown as intermediate intensity. In the other 14 knees with no PSM observed by arthroscopy, the low intensity band was not shown on MR imaging. In all 20 knees, a similar low intensity band was shown about 1 cm cranial to the medial condyle of the femur. This should not be diagnosed as PSM. The low intensity band seen on T1- and T2-weighted MR images and its anatomical relation to the medial condyle are important in diagnosing PSM. (author).

    Full Text Available Abstract We report a thirteen-year-old tennis player with knee hemarthrosis caused by low factor XIII activity. She visited our hospital because of medial peripatellar pain for two years. Although there was no abnormal sign in X-ray or MRI, diagnostic arthroscopy was performed. It revealed some cartilage debris, medial plica and complete septum of suprapatellar plica. Removing the debris by washing out and resecting the medial plica, she could return to play tennis without perioperative symptom. Two months after the first operation, her knee got swelling without any apparent cause. Since 20 ml blood was aspirated twice and MRI revealed suprapatellar mass, we performed arthroscopy again. Suprapatellar mass was old blood clot covered with complete suprapatellar plica. Resection of suprapatellar plica and washing out blood clot were performed, and severe postoperative hemarthrosis was progressively occurred. As factor XIII level was 54% preoperatively, we diagnosed that this condition was caused by low activity level of the factor and administered factor XIII concentrates. The level got improved to 129% and then hemarthrosis gradually relieved. She had no signs of recurrence. We should keep in mind of low factor XIII activity case in case of unexplained postoperative hemarthrosis after arthroscopy because consumption of the factor might promote this condition.

    To retrospectively determine characteristics of contrast-filled acetabular labral clefts in patients under the age of 17 years at MR arthrography (Mra) correlated with arthroscopy, which may impact the thinking regarding the existence of a sublabral sulcus. After IRB approval, 41 patients under the age of 17 who had MRa were identified. The following observations of contrast-filled clefts were assessed: (1) presence/absence, (2) location, (3) depth, (4) abnormal signal within the labrum and (5) shape (linear, gaping, complex). Fisher's exact and the Wilcoxon matched-pairs signed-rank test were performed. Interreader agreement was calculated with Cohen's k. Reader 1 found clefts in 41 %. Depth was less than half in 6 %, more than half in 65 % and full thickness in 29 %. Shape was linear in 53 %, gaping in 18 % and complex in 29 %. Signal changes occurred in 88 %. Reader 2 found clefts in 29 %. Depth was less than half in 17 %, more than half in 58 % and full thickness in 25 %. Shape was linear in 50 %, gaping in 42 % and complex in 17 %. Signal changes occurred in 50 %. None of the clefts fulfilled the criteria for a sublabral sulcus at MRa and arthroscopy. None of the clefts found in our subjects under the age of 17 years met the MRa and arthroscopy criteria for a sublabral sulcus, which supports the theory that such clefts represent labral tears.

    Full Text Available Auricular acupuncture (AA is effective in treating various pain conditions, but there have been no analyses of AA for the treatment of pain after ambulatory knee surgery. We assessed the range of analgesic requirements under AA after ambulatory knee arthroscopy. Twenty patients randomly received a true AA procedure (Lung, Shenmen and Knee points or sham procedure (three non-acupuncture points on the auricular helix before ambulatory knee arthroscopy. Permanent press AA needles were retained in situ for one day after surgery. Post-operative pain was treated with non-steroidal anti-inflammatory ibuprofen, and weak oral opioid tramadol was used for rescue analgesic medication. The quantity of post-operative analgesics and pain intensity were used to assess the effect of AA. The incidence of analgesia-related side effects, time to discharge from the anesthesia recovery room, heart rate and blood pressure were also recorded. Ibuprofen consumption after surgery in the AA group was lower than in the control group: median 500 versus 800 mg, P = 0.043. Pain intensity on a 100 mm visual analogue scale for pain measurement and other parameters were similar in both groups. Thus AA might be useful in reducing the post-operative analgesic requirement after ambulatory knee arthroscopy.

    Full Text Available Clinical, arthrographic, and arthroscopic findings in 53 patients with acutely torn anterior cruciate ligaments (ACLs were documented. Arthroscopy and instability tests under anesthesia were performed on all patients within 2 weeks after the initial injury. Twenty-three patients complained of extension blocks, and localized tenderness on the medial side was revealed in 26 patients at the initial examination. Aspiration from joints exhibited hemarthrosis in 52 patients. Arthroscopy revealed ACL ruptures in all patients. Four Segond's fractures, 26 meniscus tears (8 medial and 18 lateral, 1 osteochondral fracture, and 19 medial collateral ligament ruptures were revealed. Arthroscopy detected only 1 of the 5 ruptures of the posteromedial corner of the medial meniscus, which were noted on arthrography. Three ACL stumps were protruding among the femorotibial joint, which seemed to be restricting full extension. Statistical analysis showed that tenderness on the medial side was not revealed more frequently in knees with medial collateral ligament injuries than in the others. The volume of aspirated fluids in knees with no leakage in arthrography significantly increased over those with leakages (p < 0.05. Diagnosis of ACL injuries should be completed by clinical, arthrographic, and arthroscopic examinations.

    The scapholunate joint is one of the most involved in wrist injuries. Its stability depends on primary and secondary stabilisers forming together the scapholunate complex. This ligamentous complex is often evaluated by wrist arthroscopy. To avoid surgery as diagnostic procedure, optimization of MR imaging parameters as use of three-dimensional (3D) sequences with very thin slices and high spatial resolution, is needed to detect lesions of the intrinsic and extrinsic ligaments of the scapholunate complex. The paper reviews the literature on imaging of radial-sided carpal ligaments with advanced computed tomographic arthrography (CTA) and magnetic resonance arthrography (MRA) to evaluate the scapholunate complex. Anatomy and pathology of the ligamentous complex are described and illustrated with CTA, MRA and corresponding arthroscopy. Sprains, mid-substance tears, avulsions and fibrous infiltrations of carpal ligaments could be identified on CTA and MRA images using 3D fat-saturated PD and 3D DESS (dual echo with steady-state precession) sequences with 0.5-mm-thick slices. Imaging signs of scapholunate complex pathology include: discontinuity, nonvisualization, changes in signal intensity, contrast extravasation (MRA), contour irregularity and waviness and periligamentous infiltration by edema, granulation tissue or fibrosis. Based on this preliminary experience, we believe that 3 T MRA using 3D sequences with 0.5-mm-thick slices and multiplanar reconstructions is capable to evaluate the scapholunate complex and could help to reduce the number of diagnostic arthroscopies.

    Objective. To demonstrate the MR imaging findings of anterolateral impingement (ALI) of the ankle.Design and patients. Nine patients with a history of ankle inversion injury and chronic lateral ankle pain were imaged with MR imaging, and the findings correlated with the results of arthroscopy. Three additional patients with clinically suspected ALI of the ankle were also included. Ankle MR imaging studies from 20 control patients in whom ALI was not suspected clinically were examined for similar findings to the patient group.Results. MR imaging findings in the patients with ALI included a soft tissue signal mass in the anterolateral gutter of the ankle in 12 of 12 (100%) cases, corresponding to the synovial hypertrophy and soft tissue mass found at arthroscopy in the nine patients who underwent arthroscopy. Disruption, attenuation, or marked thickening of the anterior talofibular ligament was seen in all cases. Additional findings included signs of synovial hypertrophy elsewhere in the tibiotalar joint in seven of 12 patients (58%) and bony and cartilaginous injuries to the tibiotalar joint in five of 12 (42%). None of the control patients demonstrated MR imaging evidence of a soft tissue mass in the anterolateral gutter.Conclusions. ALI of the ankle is a common cause for chronic lateral ankle pain. It has been well described in the orthopedic literature but its imaging findings have not been clearly elucidated. The MR imaging findings, along with the appropriate clinical history, can be used to direct arthroscopic examination and subsequent debridement. (orig.)

    Although in widespread clinical use, evidence of the diagnostic accuracy of radiographic parameters for the diagnosis of scapholunate ligament injuries is scarce. The objective of this study was to evaluate the scapholunate (SL) angle, radiolunate (RL) angle and SL gap as diagnostic parameters for these lesions. Eight hundred forty nine patients, who underwent wrist arthroscopy at our institution because of wrist pain were included in a retrospective analysis. In all patients the SL angle, RL angle and SL gap were measured on preoperative radiographs. These parameters were correlated with the actual finding of the SL ligament during arthroscopy. Optimal test thresholds were calculated as well as sensitivity, specificity and the likelihood ratios of each parameter. All three parameters proved useful in statistical analysis. The optimal cut-off points for diagnosing lesions of the SL ligament were calculated as 62.5 for the SL angle, 12.5 for the RL angle and 2.5 mm for the SL gap. SL angles had the greatest specificity (0.93). We were able to validate plain radiographs as a reliable tool in the work-up of patients with suspected SL ligament injuries. However, wrist arthroscopy remains the gold standard in diagnosing and treating these lesions. (orig.)

    Arthroscopy has become indispensable for performing tibiotalar and subtalar arthrodesis. Now in 2015, it is the gold-standard surgical technique, and open surgery is reserved only for cases in which arthroscopy is contraindicated: material ablation after consolidation failure, osteophytes precluding a work chamber, excentric talus, severe malunion, bone defect requiring grafting, associated midfoot deformity, etc. The first reports of arthroscopic tibiotalar and subtalar arthrodesis date from the early 1990s. Consolidation rates were comparable to open surgery, but with significantly fewer postoperative complications: infection, skin necrosis, etc. Arthroscopy was for many years reserved to moderate deformity, with frontal or sagittal deviation less than 10°. The recent literature, however, seems to extend indications, the only restriction being the surgeon's experience. Tibiotalar arthrodesis on a posterior arthroscopic approach remains little used. And yet the posterior work chamber is much larger, and initial series showed consolidation rates similar to those of an anterior approach. The surgical technique for posterior tibiotalar arthrodesis was described by Van Dijk et al., initially using a posterior para-Achilles approach. This may be hampered by posterior osteophytes or ankylosis of the subtalar joint line (revision of non-consolidated arthrodesis, sequelae of calcaneal thalamus fracture) and is now used only by foot and ankle specialists. Posterior double tibiotalar-subtalar arthrodesis, described by Devos Bevernage et al., is facilitated by transplantar calcaneo-talo-tibial intramedullary nailing. PMID:26797006

    Objective. To describe the MR features of mucoid degeneration of the anterior cruciate ligament (ACL) in a series of patients with MRI findings that were mistaken for tears in the majority of cases but who were found to have an intact ligament at arthroscopy. We will suggest a pathologic entity corresponding to this finding and describe some characteristic features that can be used to identify this entity on MRI.Design. A retrospective analysis of 10 MRI examinations of the knee was performed after arthroscopic evaluation. Prearthroscopic MRI findings had been interpreted as a tear in six patients prospectively and in the remaining four the diagnosis of mucoid degeneration was suggested and ultimately proven. All patients had an intact ACL by preoperative clinical examination, examination under anesthesia, and at arthroscopy.Results. MRI examinations demonstrated an ill-defined ACL, greater in girth than the normal ligament and characterized by increased signal on all sequences. The high-signal ligament was oriented in the normal direction of the ACL. The overall appearance of the ligament was retrospectively described as like a celery stalk. Arthroscopy demonstrated mechanically intact ligaments with a normal to expanded external appearance. Probing of three of the ligaments caused a material to be expressed and pathologic evaluation resulted in the diagnosis of cystic, mucoid degeneration.Conclusion. Mucoid degeneration and an intact ACL can be suspected when an apparently thickened and ill-defined ligament with increased signal intensity on all sequences is identified in a patient with a clinically intact ligament.

    The orthopaedic surgeons cannot predict the functional results after a distal intra articular radius fracture. The intra-articular incongruity of more than 1 mm is associated with the development of secondary osteoarthrosis. The wrist arthroscopy became an essential help for the reduction of these fractures. The hand is normally in an upright position with a traction of approximately 4-5 kg which facilitates the reduction of the extra-articular fracture component. It is possible to use a technique of horizontal traction. The arthroscopy allows the reduction and control of the fixing of the various fragments, but also the treatment associated lesions associated. One randomized study, which compared 34 arthroscopically treated fractures with 48 openly treated, concluded that the arthroscopy-treated group had better outcome, better reduction, better grip strength and better range of motion than the openly treated group. The treatment of intra articular distal radius fractures with arthroscopic assistance is thus the guaranteeing of the most anatomical reduction of articular surface. It allows the diagnosis and the treatment of the associated lesions, decreases the peripheral fibrous scars of soft tissues by avoiding initially extensive approaches and finally gives better functional results.

    The clinical outcome of an intraarticular distal radius fracture is generally thought to be associated with the following factors: amount of radial deformity, joint congruity, and associated soft-tissue injuries. The proposed technique to manage this fracture pattern that involves a displaced volar lunate facet fragment uses wrist arthroscopy and pinning. Distraction of the fracture before arthroscopy is accomplished either by external fixation or by the arthroscopy tower. A freer elevator is introduced dorsally to disimpact the fragments, and next, a nerve hook is used to reduce the volar lunate facet, which is subsequently pinned to the radial styloid. The remaining fragments are reduced with interfragmentary pin fixation, and this anatomical articular construct is fixed to the radial metaphysis. The advantages of this technique are: (a) accurate assessment of articular congruency by direct visualization, (b) identification and repair of associated lesions, and (c) minimal soft tissue disruption. Potential disadvantages of external fixation supplemented by interfragmentary pins may be that it does not provide for rigid stable fixation, and therefore, does not allow for early motion compared to open reduction and internal fixation. Furthermore, it is technically challenging, and is therefore suggested as an alternative for the aforementioned fracture pattern. PMID:16974217

    The optimal forearm boom should facilitate dynamic investigation of the wrist and approaches for wrist arthroscopy. It should be safely fixed at the operating table without any contact with the patient. It must be compatible with the arm of any patient and should be sterilisable. Repositioning of distal radius fractures, fluoroscopy and insertion of Kirschner-wires should not be restricted. According to these criteria the current investigators designed a new forearm boom which was subsequently used in 19 wrist arthroscopies and 9 distal radius fracture fixations. Twenty-eight patients with heights between 150 and 205 cm and forearm lengths between 17.5 to 37 cm were treated. Preoperatively, wrist motion was tested in those 19 wrists, that underwent wrist arthroscopy, before and after fixation by the forearm boom and any restriction due to usage of the novel device was found. The new forearm boom satisfied all of the criteria cited above. Therefore the current authors believe the new forearm boom may be valuable for the indications mentioned. PMID:21209480

    Wrist arthroscopy for the distal radius fractures is an effective adjunct to evaluate the reduction of intraarticular fragments and soft tissue injuries. In recent years, volar locking plate fixation has become popular, and arthroscopic procedures for distal radius fracture reduction have become problematic because vertical traction has to be both on and off during surgery. We developed a plate presetting arthroscopic reduction technique to simplify the combination of plating and arthroscopy. The fracture was reduced, and anatomic alignment was regained under an image intensifier, and then the volar locking plate was preset. Wrist arthroscopy was introduced under vertical traction, and the intraarticular condition was assessed. If dislocations of the intraarticular fragments were residual, they were reduced arthroscopically, and soft tissue injuries were treated subsequently. Finally, the traction was removed, and the plate was securely fixed. Since May 2005, the authors have used this technique in more than 50 patients. This article will review the history, indications, contraindications, technique, rehabilitation, and complications for the plate presetting arthroscopic reduction technique for distal radius fractures.

    Standalone open reduction-internal fixation (ORIF) of unstable ankle fractures is the current standard of care. Intraoperative stress radiographs are useful for assessing the extent of ligamentous disruption, but arthroscopic visualization has been shown to be more accurate. Concomitant arthroscopy at the time of ankle fracture ORIF is useful for accurately diagnosing and managing syndesmotic and deltoid ligament injuries. The arthroscopic ankle drive-through sign is characterized by the ability to pass a 2.9-mm shaver (Smith & Nephew, Andover, MA) easily through the medial ankle gutter during arthroscopy, which is not usually possible with both an intact deltoid ligament and syndesmosis. This arthroscopic maneuver indicates instability after ankle reduction and fixation and is predictive of the need for further stabilization. Furthermore, when this sign remains positive after fracture fixation, it may guide the surgeon to further evaluate the adequacy of fixation for the possible need for further fixation of the syndesmosis or deltoid. We present the case of an ankle fracture managed with arthroscopy-assisted ORIF and describe the clinical utility of the arthroscopic ankle drive-through sign. PMID:27462542

    To evaluate the feasibility of cine MRI for the detection of scapholunate dissociation (SLD) and to compare the sensitivity and specificity of cine MRI with those of cineradiography and arthroscopy. To evaluate feasibility, healthy subjects underwent cine MRI of the wrist. To evaluate sensitivity and specificity, patients with clinically suspected scapholunate ligament (SLL) injury after trauma to the wrist were prospectively included and underwent radiographic examination, cineradiography, and cine MRI. In 25 out of 38 patients, subsequent arthroscopy was performed. Results of cineradiography and cine MRI correlated with those of arthroscopy. Cine MRI was of diagnostic quality in all healthy subjects and patients with good interrater agreement. There was excellent correlation between cineradiography and cine MRI. Scapholunate distance differed significantly between healthy subjects and patients with scapholunate dissociation (p < 0.001), but not between imaging modalities in the patient group. Cine MRI had 85 % sensitivity and 90 % specificity for the detection of SLD. Cine MRI of the wrist is a fast and reliable technique for the detection of SLD with diagnostic accuracy comparable to cineradiography. It can be easily implemented as a routine clinical MRI examination, facilitating diagnostic workup of patients with suspected SLD while avoiding radiation exposure. (orig.)

    Osteochondritis (osteochondrosis) dissecans (OCD) is a common condition in children, adolescents, and young adults. Describing OCD together with osteochondral fractures and epiphyseal ossification disturbances and considering these three conditions as one entity has caused much confusion. Age distribution and localization combined with the radiologic and surgical presentation distinguishes these conditions. Osteochondritis dissecans represents an osseous lesion with secondary involvement of the overlying cartilage. Beginning as avascular osteonecrosis, OCD forms a transitional zone that harbors the potential of restoration with complete healing or progression to an osseous defect. Mechanical and traumatic factors are etiologically dominant in OCD, but a predisposition seems to be a contributing factor in some patients. Osteochondritis dissecans is generally diagnosed by conventional radiology. Its therapy is determined by the stage of the lesion and MRI will become the method of choice for staging. Intact cartilage, contrast enhancement of the lesion, and absent ``cystic`` defects are findings of MRI stage I and justify conservative therapy, obviating arthroscopy. Cartilage defect with or without incomplete separation of the fragment, fluid around an undetached fragment, and a dislodged fragment are MRI findings observed in stage II and require arthroscopy with possible intervention. Thus, MRI can noninvasively separate non-surgical from possibly surgical lesions and should replace diagnostic arthroscopy. (orig.) With 13 figs., 4 tabs., 49 refs.

    Although MRI prognostic features for juvenile osteochondritis dissecans (JOCD) have been determined, the natural history of JOCD on serial MRI has not been fully documented. To document the natural history of JOCD on serial MRI and to correlate this with arthroscopy and clinical outcome over a 5-year follow-up. Twenty-one knees in 19 patients (15 boys, 4 girls; age range 5-15 years) with JOCD underwent MRI and clinical follow-up over 5 years. Lesions were classified as stable or unstable on MRI and compared with clinical and arthroscopic data. On 5-year follow-up, 17 of 19 patients were asymptomatic and 2 of 19 had minimal pain. Fourteen arthroscopies were performed on 11/21 knees. One of twenty-one had fragment fixation. On initial MRI, eight knees had marked fragmentation, high signal at the fragment/bone interface and incomplete defects in the hyaline cartilage (MRI stage III-stable), but no tear. Of these, five had arthroscopy, all confirming intact cartilage. One of twenty-one knees was unstable (MRI stage IVb) with a detached osteochondral fragment, requiring surgery. Despite extensive subchondral bone changes on MRI, all cases with intact cartilage (95%) improved with conservative treatment. Early MRI allows prompt diagnosis and institution of conservative treatment. This results in healing and avoidance of surgery in most patients. (orig.)

    To determine the ability of 3.0T magnetic resonance (MR) imaging to identify partial tears of the anterior cruciate ligament (ACL) and to allow distinction of complete from partial ACL tears. One hundred seventy-two patients were prospectively studied by 3.0T MR imaging and arthroscopy in our institution. MR images were interpreted in consensus by two experienced reviewers, and the ACL was diagnosed as being normal, partially torn, or completely torn. Diagnostic accuracy of 3.0T MR for the detection of both complete and partial tears of the ACL was calculated using arthroscopy as the standard of reference. There were 132 patients with an intact ACL, 17 had a partial, and 23 had a complete tear of the ACL seen at arthroscopy. Sensitivity, specificity, and accuracy of 3.0T MR for complete ACL tears were 83, 99, and 97%, respectively, and, for partial ACL tears, 77, 97, and 95%, respectively. Five of 40 ACL lesions (13%) could not correctly be identified as complete or partial ACL tears. MR imaging at 3.0T represents a highly accurate method for identifying tears of the ACL. However, differentiation between complete and partial ACL tears and identification of partial tears of this ligament remains difficult, even at 3.0T. (orig.)

    To evaluate the correlation between anterior cruciate ligament (ACL) tear and straightened, vertically oriented lateral collateral ligament (LCL). This study included 556 patients who underwent MRI of the knee and were divided into three subsets based on ACL morphology. Subset 1 included patients with unequivocal normal ACL. Subset 2 included patients with unequivocal ACL tears. Subset 3 included patients with doubtful ACL who underwent arthroscopy. MR images were reviewed and sensitivity and specificity of vertically oriented LCL as an indirect sign of ACL tear were calculated. The MRI results were as follows: subset 1, out of 282 patients, 270 had oblique LCL and 12 demonstrated vertical LCL; subset 2, out of 212 patients, 189 demonstrated vertical LCL and 23 revealed oblique LCL; subset 3, out of 62 patients, 28 patients with vertical orientation of LCL had a possible ACL tear. Patients with oblique LCL orientation (34) were reported as probably having normal ACL. On comparison with arthroscopy, in 28 patients who we reported as having possible ACL tears, there were 17 patients with torn ACL. The rest of the 11 patients revealed no ACL tears. In the group of 34 patients in whom we reported possible normal, arthroscopy-confirmed tear in 5 patients. Sensitivity and specificity of vertical LCL as an indirect sign of ACL tear was found to be 88% and the specificity 92.85%. Vertically oriented LCL is a useful indirect MRI sign of ACL tear and aids in making a diagnosis, when ACL appearance is equivocal. (orig.)

    Full Text Available INTRODUCTION Rotator cuff disease is the most common cause of shoulder pain. Ultrasonography being non-invasive, widely available, more cost-effective method and is the first choice in imaging of rotator cuff tears. Arthroscopy of shoulder is considered as the gold standard for diagnosis of rotator cuff tears. Objective of this study was to compare the diagnostic accuracy of high-resolution ultrasonography of shoulder for rotator cuff tears with arthroscopy of shoulder. METHODS Thirty patients clinically suspected to have rotator cuff tear who underwent ultrasonography and arthroscopy of shoulder were included in the study. Duration of study was for two years. All ultrasonography examinations were conducted in ultrasound machine using GE Voluson 730 PRO high frequency (10-12 MHz linear array transducer done by two experienced radiologists. Arthroscopies were done by two experienced shoulder arthroscopic surgeons. RESULTS Age of the patients with rotator cuff tears ranged from 40 to 80 years. 57% were females and 43% were males among the patients who had rotator cuff tears. 71.43% of the rotator cuff tears were found in the dominant arm. 64.28% of patients with rotator cuff tear had given history of fall or trauma to the corresponding shoulder within 6 months prior to presentation. 39.28% of patients who had rotator cuff tears were known diabetics. Supraspinatus tendon was the most commonly affected tendon, followed by infraspinatus and subscapularis tendons. For overall detection of rotator cuff tears, ultrasonography in comparison with the arthroscopy has sensitivity and specificity of 92.85% and 100%. For detection of full thickness rotator cuff tear, its sensitivity and specificity was 94.73% and 100% and for partial thickness rotator cuff tears 76.92% and 100%. Ultrasonography has 100% sensitivity and specificity for detection of supraspinatus full thickness tear. For supraspinatus partial thickness tear, sensitivity and specificity was 88

The developed methodological approaches are distinguished for their high sensitivity (89.7% and specificity (95.2%, which could estimate changes in arthrosis just at the stage of hyperhydration and dechondral changes and monitor long the chondroprotective effect of synvisc. The agent was noted to have a positive effect at the stage of hyperhydration and dechondral changes and in grade I–II intrachondral changes and to be able to prevent or stop the progression of OA in later (II–III X-ray stages. The effect of synvisc did not depend on disease duration and patient age, but it decreased in the presence of marked articular anatomic and morphological changes. The administration of the agent could reduce or preclude the use of nonsteroidal anti-inflammatory drugs or intraarticular glucocorticoids n 96% of cases.Conclusion. Arthroscopy and MRI make possible to recognize arthrosis in its earliest stage and to monitor the effect of drugs on the cartilage. The use of synvisc in early-stage gonarthrosis allows a long-term symptomatic effect and some structure-modifying activity.

    To evaluate the diagnostic value of MRI of the shoulder. Between January and June 1997, shoulder MRI and arthroscopy were performed in a total of 48 patients with shoulder pain (n=3D30) or shoulder instability (n=3D18). Forty-five were males and three were females; their ages ranged from 16 to 67 (mean 32.5) years. The period between shoulder MRI and arthroscopy was between one and 390 (mean, 42.2) days. Twenty-six patents underwent MR arthrography (AMR), and 22 conventional MRI(CMR). Each image was analyzed for rotator cuff injury, glenoid labral injury, SLAP lesion, and biceps tendon injury. On arthroscopy, one disease was found in 34 patients, two were found in six, three diseases were found in seven, and one patient had four diseases. Arthroscopic diagnosis was as follows:rotator cuff injury, 29;SLAP lesion, 12;glenoid labral injury, 10;biceps tendon injury, 4;subacromial bursitis, 2;chronic synovitis, 1;adhesive capsulitis, 1;superior glenohumeral ligament injury, 1;normal, 1. For rotator cuff injury, the sensitivity of MRI was 65.5% and specificity was 93.0% (AMR:66.7%, 95.8%, CMR:65.2%, 86.4%). For SLAP lesion, sensitivity was 58.3% and specificity was 97.2% (AMR:66.7%, 100%, CMR:50%, 93.8%);for glenoid labral injury, sensitivity was 80.0% and specificity was 89.5% (AMR:85.7%, 84.2%, CMR:66.7%, 94.7%), and for biceps tendon injury, the false negative rate was 100%. In cases involving glenoid labral injury, the diagnostic accuracy of shoulder MRI was relatively high;in rotator cuff injury and SLAP lesion, however, diagnosis was limited, and in biceps tendon injury was difficult. We suggest, however, that MR arthrography has certain diagnostic advantages over conventional MRI.=20.

  3. Reactive synovitis of the knee joint: MR imaging appearance with arthroscopic correlation

    International Nuclear Information System (INIS)

    Objective. To evaluate the use of routine MR imaging sequences in detecting and characterizing secondary reactive synovitis of the knee joint using arthroscopy as the standard of reference.Design and patients. Fifty consecutive patients with a history of knee pain who were referred for MR imaging and subsequently underwent arthroscopy of the knee comprised the study group. MR images were evaluated for the presence and appearance of synovitis reflected in synovial thickening and irregularity. Synovial thickening was graded on MR imaging as follows: 0=normal, 1=thin line of increased signal intensity, 2=increased signal intensity with frond-like or hair-like projections and a granular appearance of joint fluid. Standard knee imaging protocols were used.Results. The sensitivity, specificity, and accuracy of MR imaging in detecting synovitis compared with arthroscopy were 88%, 97%, and 95%, respectively. Grade 1 synovitis was best seen on proton-density-weighted images, demonstrating increased signal intensity of the synovium against the relatively low signal intensity of the joint fluid. Grade 2 synovitis was best seen on proton-density images and T2-weighted spin echo and fast spin echo images with fat saturation, demonstrating a granular and linear hair-like appearance of joint fluid. Axial and sagittal imaging planes were most helpful in the diagnosis of synovitis.Conclusion. Routine MR pulse sequences are useful in identifying the presence and extent of synovial abnormalities. The detection of different stages of synovial pathology should become an important part of the evaluation of the post-traumatic patient as treatment may be altered as a result. (orig.)

    Background. In magnetic resonance imaging (MRI) with 3D-double-echo steady-state (3D-DESS) sequences, the cartilage-synovial fluid contrast is reported to be better with a flip angle of 90 deg than with the conventional flip angle of 40 deg, and the detection rate of knee cartilage injury may be improved. Purpose. To compare the diagnostic performance and certainty of diagnosis with 3D-DESS images made using two flip angle settings, 40 deg and 90 deg, for knee cartilage surface lesions of Grade 2 or above confirmed by arthroscopy. Material and Methods. Images were obtained with 3D-DESS flip angles of 40 deg and 90 deg at 1.0T in 13 consecutive patients (2 men, 11 women, age range 18-68 years) evaluated for superficial cartilage injury by arthroscopy. Two radiologists classified the presence or absence of cartilage damage of >=Grade 2 as 'positive (p)' or 'negative (n)', respectively. The rate of agreement with arthroscopic diagnosis was then examined, and the diagnostic performance compared. Diagnostic confidence was assessed scoring the presence or absence of cartilage damage into three categories: 3 = can diagnose with absolute confidence; 2 = can diagnose with a level of certainty as probably present or probably absent; and 1 = cannot make a diagnosis. Results. In a comparison of the rate of agreement between diagnosis by 3D-DESS images and arthroscopy, the rate of agreement was significantly higher and diagnostic performance was better in 90 deg images for the medial femoral condyle only. Diagnostic confidence was significantly better with 90 deg flip angle images than with 40 deg flip angle images for all six cartilage surfaces. Conclusion. In evaluating knee cartilage surface lesions with 3D-DESS sequences, a flip angle setting of 90 deg is more effective than the conventional setting of 40 deg

  5. Evaluation of anterior cruciate ligament ruptures by three dimension MR imaging

    International Nuclear Information System (INIS)

    Objective: To compare the diagnostic performance of conventional 2D and 3D Cube MR imaging to identify complete and partial tears of anterior cruciate ligament (ACL). Methods: Forty patients suspected of having tears of anterior cruciate ligament were prospectively studied by 3.0 T conventional 2D and 3D Cube MR imaging and arthroscopy. MR images were interpreted in consensus by two experienced radiologists, and the ACL was diagnosed as being normal, partially torn, or completely torn. Diagnostic accuracy of 2D and 3D Cube MR for the detection of both complete and partial tears of ACL was calculated using arthroscopy as the standard of reference. Area under curve (AUC) of both methods were calculated using ROC curves and were compared using Hanley and McNeil curve comparison. Results: Sixteen patients had intact ACL, 12 had complete tear, and 12 had partial tear of the ACL at arthroscopy. For complete ACL tear, AUC of 2D MR and 3D Cube was 0.839 and 0.923 respectively, and there was no significant difference on ROC curves (Z=1.245, P=0.213). For partial ACL tears, AUC of 2D and 3D Cube MR were 0.643 and 0.881 respectively, and there was significant difference on ROC curves (Z=2.384, P=0.017). Conclusions: Both 2D MR and 3D Cube MR have high sensitivity and specificity for identifying the complete ruptures of ACL. 3D Cube MRI appears to be superior identifying partial rupture of ACL.

    Full Text Available Abstract Objective To examine the diagnostic accuracy of standard clinical tests for the shoulder in recreational athletes with activity related pain. Design Cohort study with index test of clinical examination and reference standard of arthroscopy. Setting Sports Medicine clinic in Sheffield, U.K. Participants 101 recreational athletes (82 male, 19 female; mean age 40.8 ± 14.6 years over a six year period. Interventions Bilateral evaluation of movements of the shoulder followed by standardized shoulder tests, formulation of clinical diagnosis and shoulder arthroscopy conducted by the same surgeon. Main Outcome Measurements Sensitivity, specificity, likelihood ratio for a positive test and over-all accuracy of clinical examination was examined retrospectively and compared with arthroscopy. Results Isolated pathology was rare, most patients (72% having more than one injury recorded. O'Brien's clinical test had a mediocre sensitivity (64% and over-all accuracy (54% for diagnosing SLAP lesions. Hawkins test and Jobe's test had the highest but still not impressive over-all accuracy (67% and sensitivity (67% for rotator cuff pathology respectively. External and internal impingement tests showed similar levels of accuracy. When a positive test was observed in one of a combination of shoulder tests used for diagnosing SLAP lesions or rotator cuff disease, sensitivity increased substantially whilst specificity decreased. Conclusions The diagnostic accuracy of isolated standard shoulder tests in recreational athletes was over-all very poor, potentially due to the majority of athletes (71% having concomitant shoulder injuries. Most likely, this means that many of these injuries are missed in general practice and treatment is therefore delayed. Clinical examination of the shoulder should involve a combination of clinical tests in order to identify likely intra articular pathology which may warrant referral to specialist for surgery.

    Background As the triangular fibrocartilage complex (TFCC) anchors the distal radius to the ulna via the radioulnar ligament (RUL), a severely displaced distal fragment of the radius may be associated with a foveal avulsion of the TFCC. The purpose of this retrospective study was to assess, radiographically and arthroscopically, the relationship between displacement of the radius, the ulnar styloid, and avulsion of the RUL resulting in distal radioulnar joint (DRUJ) instability. Materials and Methods Twenty-nine wrists of 29 patients with intra- and extra-articular distal radius fractures/malunion who underwent reduction or a corrective osteotomy of the displaced/malunited fracture, and/or wrist arthroscopy, were assessed radiographically and arthroscopically. Radial translation, radial inclination, radial shortening, volar or dorsal tilt, and the presence of an ulnar styloid fracture with more than 4 mm of displacement were measured from the initial films. Radiocarpal arthroscopy was used to assess peripheral lesions of the TFCC, while DRUJ arthroscopy was used to assess the foveal attachment. The relationship between displacement of the distal radius or the ulnar styloid fracture and the TFCC injury, including avulsion of the RUL, was recorded. Results Univariate analysis revealed that increased radial translation, decreased radial inclination, increased radial shortening, and an ulnar styloid fragment radially displaced by more than 4 mm were significant predictors of RUL avulsion at the fovea. Volar or dorsal tilt of the radius and ulnar variance did not correlate with RUL avulsion or TFCC injuries. Multiple logistic regression analysis revealed that radial translation was an independent risk factor of foveal avulsion of the RUL. Conclusions Increased radial translation and radial shortening and decreased radial inclination of the distal fragment can be associated with a foveal avulsion of the RUL. Radial translation can be an independent risk

    Background Soft tissue injuries associated with distal radius fractures have been reported by some authors. Arthroscopy can be used to evaluate the condition of the articular surface and intracarpal soft tissues and as an aid to treatment. There are three intracarpal soft tissues of particular importance: the triangular fibrocartilage complex (TFCC), the scapholunate interosseous ligament (SLIL), and the lunotriquetral interosseous ligament (LTIL). The purpose of this study was to evaluate intracarpal soft tissue injuries and their relationships with fracture types during arthroscopic surgical treatment of distal radius fractures. Methods Eighty-nine patients in our hospital underwent surgical treatment by arthroscopy for a fracture of the distal end of the radius. They ranged in age from 17 to 92 years (mean, 62.2 years), and comprised 20 men (mean age, 45.6 years) and 69 women (mean age, 66.5 years). The AO classification data on plain radiographs indicated A2 fracture in four patients, A3 fracture in 10 patients, C1 fracture in two patients, C2 fracture in 24 patients, and C3 fracture in 49 patients. Wrist arthroscopy was performed with vertical traction, and intracarpal soft tissues were examined. For assessment of the TFCC in the radiocarpal space, the Palmar classification was used. For assessment of the SLIL and LTIL in the midcarpal space, the Geissler classification was used. Results TFCC injury was present in 59% of cases, SLIL injury in 54.5% of cases, and LTIL injury in 34.5% of cases. Only 17.1% of patients (14/82 patients) were negative for all three types of injury. In 81% of cases (72/89 patients), some intracarpal soft tissue injury was present in association with the fracture. Conclusions The fracture was complicated by TFCC injury in 59% of patients, SLIL injury in 54.5% of patients, and LTIL injury in 34.5% of patients, irrespective of the fracture type. PMID:24004506

    Ulno carpal abutments secondary to the sequels of a fracture of the radius are often due to the inversion of the distal radio ulnar index by shortening relative to the radius. This positive ulnar variance eventually leads to an abutment between the head of the ulnar and the proximal articular face of the lunate with alteration of the cartilaginous carpal surfaces. The wrist arthroscopy makes diagnosis and treatment possible in a less invasive way. The patients are operated on as outpatients under local regional anaesthetic using a pneumatic tourniquet. The arthroscope is positioned using the 3-4 radio carpal opening permitting exploration of the joint. The surgical treatment is performed by arthroscopy using a burr and going in through the 6R radio carpal opening. In this way we use the technique of partial resection of the distal ulna. We have a series of 62 patients who have benefited from the technique of partial resection of the ulnar head by arthroscopy. There were 30 men and 32 women. The average age was 66 years old (between 45 and 82). Our average follow-up is 32 months (between 12 and 60 months). Recovery of mobility was immediate in all cases with persistent pain in the radio ulnar joint in 8 cases. Arthroscopic treatment of ulno carpal abutment has proved itself effective and innocuous. It should nevertheless be reserved for operations on small sized inversions of the distal radio ulnar index (less than 5 mm). In the event of larger ulnar variances we prefer ulnar shortening osteotomy. The other techniques will be restricted to cases where the distal radio ulnar joint has been impaired. PMID:17361890

    Full Text Available Introduction: Surgical excision of the ununited ossicles has been suggested for unresolved sequelae of Osgood-Schlatter disease in adults resistant to conservative measures. We report a case where arthroscopy was used to excise the ossicles. A bird eye view from the superolateral portal was helpful in the arthroscopic procedure for excision of the deep low lesion. Case Report: A 32-year-old, male driver had anterior knee pain during walking and sports activity that had been treated conservatively for 3 months. On physical examination, there was a prominent tibial tubercle, but without palpable pain. There was obvious pain when the knee was approaching full extension. On image, a huge ununited ossicle was seen behind the patellar tendon, intruding into the joint space, and there was another two small ununited ossicles beneath the bow-shaped patellar tendon. Arthroscopy was performed through a three portals technique, and a bird eye view was achieved from the superolateral portal. The ossicles were separated from the surrounding soft tissue with a motorized shaver. The small ununited ossicles were removed by use of a grasper. The huge ossicle was removed by use of a motorized bur, and the contouring of the irregular surface of the tibial tubercle was performed. After 3 months, the patient returned to sports activities without any restrictions. Conclusion: This report shows that a huge ossicle can cause impingement in anterior knee compartment, and it can be easily removed arthroscopically under assistance of an additional portal. Keywords: Osgood-Schlatter disease; Knee; Arthroscopy; Superolateral portal.

  12. The utility of MR imaging of the shoulder joint: comparison of the MR imaging between conventional MR imaging and arthrographic MR imaging

    International Nuclear Information System (INIS)

    To evaluate the diagnostic value of MRI of the shoulder. Between January and June 1997, shoulder MRI and arthroscopy were performed in a total of 48 patients with shoulder pain (n=3D30) or shoulder instability (n=3D18). Forty-five were males and three were females; their ages ranged from 16 to 67 (mean 32.5) years. The period between shoulder MRI and arthroscopy was between one and 390 (mean, 42.2) days. Twenty-six patents underwent MR arthrography (AMR), and 22 conventional MRI(CMR). Each image was analyzed for rotator cuff injury, glenoid labral injury, SLAP lesion, and biceps tendon injury. On arthroscopy, one disease was found in 34 patients, two were found in six, three diseases were found in seven, and one patient had four diseases. Arthroscopic diagnosis was as follows:rotator cuff injury, 29;SLAP lesion, 12;glenoid labral injury, 10;biceps tendon injury, 4;subacromial bursitis, 2;chronic synovitis, 1;adhesive capsulitis, 1;superior glenohumeral ligament injury, 1;normal, 1. For rotator cuff injury, the sensitivity of MRI was 65.5% and specificity was 93.0% (AMR:66.7%, 95.8%, CMR:65.2%, 86.4%). For SLAP lesion, sensitivity was 58.3% and specificity was 97.2% (AMR:66.7%, 100%, CMR:50%, 93.8%);for glenoid labral injury, sensitivity was 80.0% and specificity was 89.5% (AMR:85.7%, 84.2%, CMR:66.7%, 94.7%), and for biceps tendon injury, the false negative rate was 100%. In cases involving glenoid labral injury, the diagnostic accuracy of shoulder MRI was relatively high;in rotator cuff injury and SLAP lesion, however, diagnosis was limited, and in biceps tendon injury was difficult. We suggest, however, that MR arthrography has certain diagnostic advantages over conventional MRI.=20

    Osteochondrosis lesions commonly occur on the femoral trochlear ridges in horses and radiography and ultrasonography are routinely used to diagnose these lesions. However, poor correlation has been found between radiographic and arthroscopic findings of affected trochlear ridges. Interobserver agreement for ultrasonographic diagnoses and correlation between ultrasonographic and arthroscopic findings have not been previously described. Objectives of this study were to describe diagnostic sensitivity and interobserver agreement of radiography and ultrasonography for detecting and grading osteochondrosis lesions of the equine trochlear ridges, using arthroscopy as the reference standard. Twenty-two horses were sampled. Two observers independently recorded radiographic and ultrasonographic findings without knowledge of arthroscopic findings. Imaging findings were compared between observers and with arthroscopic findings. Agreement between observers was moderate to excellent (κ 0.48-0.86) for detecting lesions using radiography and good to excellent (κ 0.74-0.87) for grading lesions using radiography. Agreement between observers was good to excellent (κ 0.78-0.94) for detecting lesions using ultrasonography and very good to excellent (κ 0.86-0.93) for grading lesions using ultrasonography. Diagnostic sensitivity was 84-88% for radiography and 100% for ultrasonography. Diagnostic specificity was 89-100% for radiography and 60-82% for ultrasonography. Agreement between radiography and arthroscopy was good (κ 0.64-0.78). Agreement between ultrasonography and arthroscopy was very good to excellent (κ 0.81-0.87). Findings from this study support ultrasound as a preferred method for predicting presence and severity of osteochondrosis lesions involving the femoral trochlear ridges in horses. PMID:23278908

    The subscapularis is the largest and most powerful of the rotator cuff muscles and fulfills an important role in glenohumeral movement and stability. The spectrum and implications of subscapularis muscle or tendon injury differ from injury to other rotator cuff components because of its unique structure and function. Diagnosing subscapularis injury is clinically difficult and assessment of subscapularis integrity may be limited during arthroscopy or open surgery. Diagnostic imaging plays an important part in diagnosing and evaluating the extent of subscapularis injury. The radiologist should be aware of the anatomy of the subscapularis, the variations in muscle or tendon injury, and the potential implications for treatment and prognosis. (orig.)

    Femoroacetabuler impingement (FAI) is becoming increasingly recognised as a potential pathological entity for individuals with hip pain. Surgery described to correct FAI has risen exponentially in the past 10 years with the use of hip arthroscopy. Unfortunately, the strength of evidence supporting...... both the examination and treatment of FAI does not appear to accommodate this exponential growth. In fact, the direction currently taken for FAI is similar to previously described paths of other orthopaedic and sports medicine pathologies (eg, shoulder impingement, knee meniscus tear) for which we have...

    Synovial chondromatosis (SC) is a cartilaginous metaplasy of the mesenchymal remnants of the synovial tissue of the joints. It is characterized by the formation of cartilaginous nodules in the synovium and inside the articular space (loose bodies). SC mainly affects to big synovial joints such as the knee and the elbow, being uncommon the onset within the TMJ, where 75 cases have been published. The main symptoms are pain, inflammation, limitation of the movements of the jaw and crepitation. Different methods of diagnosis include panoramic radiograph, CT, MR and arthroscopy of the TMJ. We report a new case of unilateral SC of the TMJ, including diagnostic images, treatment performed and histological analysis.

    Traumatic lesions of the hip in athletes may be clinically challenging because of the overlap in clinical presentation due to differing pathologies and the presence of multiple injuries. Imaging of the hip in the athlete has undergone a recent resurgence of interest and understanding related to the increasing accessibility and use of hip arthroscopy, which expands the treatment options available for intra-articular pathology. MR imaging and MR arthrography have a unique role in diagnosis of these pathologies, guiding the surgeon, arthroscopist, and referring clinician in their management of bony and soft tissue injury.

    This study analyzed imaging, arthroscopic findings, and treatment responses for peroneal spastic flatfoot (PSFF) caused by talocalcaneal impingement at the accessory anterolateral talar facet (AALTF) (accessory talar facet impingement) in 13 adolescents without histories of trauma and tarsal coalition. The AALTF was determined with computed tomography and MRI. Focal abutting bone marrow edema (FABME) on MRI around the AALTF was confirmed. In seven patients who underwent AALTF resection, subtalar arthroscopy was performed. All experienced alleviation PSFF after treatment; reduction in FABME was observed. AALTF resection alone is beneficial for PSFF caused by accessory talar facet impingement when peroneal spasms are restored by an injection of local anesthesia.

ACL-ruptures with an old appearance were not considered able to cause locking. Assuming that arthroscopy was the gold standard......, the following results were calculated for the overall appearance of a lesion able to cause locking: Positive predictive value = 0.85, negative predictive value = 0.77, sensitivity = 0.95, specificity = 0.53. Two knees were erroneously evaluated with no mechanical locking at MRI (one bucket-handle lesion and one...

    The localized form of pigmented villonodular synovitis of the knee is a rare condition with non-specific symptoms. This makes diagnosis especially difficult when the meniscus is affected. A full assessment with several imaging modalities can help support the preoperative diagnosis. But in the case reported here, the full clinical and paraclinical assessment (X-rays, CT arthrography and MRI) was wrong--the localized form of pigmented villonodular synovitis had mimicked a lateral meniscus injury and was only detected during arthroscopy. The lesion was excised surgically and the diagnosis was confirmed through postoperative histopathology.

    Full Text Available Hip joint instability and impingement are the most common biomechanical risk factors that put the hip joint at risk to develop premature osteoarthritis. Several surgical procedures like periacetabular osteotomy for hip dysplasia or hip arthroscopy or safe surgical hip dislocation for femoroacetabular impingement aim at restoring the hip anatomy. However, the success of joint preserving surgical procedures is limited by the amount of pre-existing cartilage damage. Biochemically sensitive MRI techniques like delayed Gadolinium Enhanced MRI of Cartilage (dGEMRIC might help to monitor the effect of surgical or non-surgical procedures in the effort to halt or even reverse joint damage.

    1984-10-01

    In a retrospective study of 47 cases of chondromalacia proved by operation, a correct diagnosis had been made by arthrography in three cases. In 44 patients a false negative finding had been obtained. A prospective study was carried out comparing single and double contrast arthrography as well as double contrast arthrotomography and scintigraphy in ten patients with typical chondropathia. It was confirmed by arthroscopy in nine cases. Only two patients with severe chondromalacia showed abnormal findings by arthrography or scintigraphy. Our investigation has led to the conclusion that arthrography is not a suitable method for demonstrating idiopathic chondropathia of the patella.

    Septic arthritis of the temporomandibular joint (TMJ) is a rare disease. The most common symptoms of this disease are acute malocclusion, limited mouth opening, swelling, and tenderness of affected TMJ. These symptoms are often confused with internal derangement of the articular disc, rheumatoid arthritis, retrodiscitis, or osteoarthritis. Therefore, differential diagnosis by image examination is required. Usually, antimicrobial treatment and surgical drainage by needle aspiration, arthroscopy, or arthrotomy are effective treatment approaches. In this study, a patient who was diagnosed with septic arthritis was treated with arthrocentesis and antibiotics without significant complications. We present a case report with a review of the literature.

    A three-year-old male greyhound was presented with acute onset right forelimb lameness because of medial displacement of the biceps tendon of origin. Ultrasonographic examination confirmed the diagnosis, and a concomitant partial tear of the medial glenohumeral ligament was detected during arthroscopy. To stabilise the biceps tendon, polypropylene mesh was fixed across the intertubercular groove to replace the torn transverse humeral retinaculum. Recovery was uneventful and lameness resolved. Fifteen months later, the dog was presented with medial displacement of the biceps tendon of origin of the left shoulder, and was treated successfully using the same technique. PMID:23614688

    We reviewed eight patients who sustained superficial peroneal nerve neuralgia after an inversion ankle sprain. Surgical exploration found anatomic abnormalities that tethered the nerve from movement during plantarflexion and inversion of the ankle. Most patients' pain improved dramatically after release and anterior transposition of the nerve. Seven joints also underwent arthroscopy, which showed intra-articular disease that was consistent with the original trauma. Five patients had reflex sympathetic dystrophy, three of which resolved after nerve release. Nerve conduction studies were not helpful. Careful physical examination and local nerve blocks were most important in making the diagnosis and prescribing treatment. All conservative measures should be exhausted before surgery is considered.

    In a large Level IV case series of 2,213 hip arthroscopies with the diagnosis of femoroacetabular impingement, the intraoperative status of the ligamentum teres (LT) was recorded as normal in 11%, frayed and/or partially torn in 88%, and completely torn in 1.5% of hips. Although specific physical examination maneuvers for detecting LT tears were not available early in the study period, thus limiting a detailed assessment of such tests, the authors identified that female gender, a lower lateral center edge angle, a higher Tonnis angle, and capsular laxity were all associated with complete LT tears. This study further supports the complex coexistence of impingement and instability.

  12. Imaging Evaluation of Superior Labral Anteroposterior (SLAP) Tears.

    Science.gov (United States)

    Grubin, Jeremy; Maderazo, Alex; Fitzpatrick, Darren

    2015-10-01

    Superior labral anteroposterior (SLAP) tears are common injuries that are best evaluated with magnetic resonance arthrography (MRA), as it provides the most detailed evaluation of the bicipital labral complex. Given the variety and complexity of SLAP tears, distention of the joint with intra-articular dilute gadolinium contrast properly separates the intra-articular biceps tendon, superior labrum, glenoid cartilage and glenohumeral ligaments to optimize assessment of these structures. This allows for increased diagnostic confidence of the interpreting radiologist and provides a better road map for the surgeon prior to arthroscopy. Indirect MRA and high-field magnetic resonance imaging are sensitive and specific alternative modalities if MRA cannot be performed.

    Contrary to general belief, arthroscopic assisted reduction in distal radius fractures can be done in an expeditious manner and with minimal consumption of operating room resources. This article presents the steps for a pleasant arthroscopic experience in detail. The technique proposed combines the benefits of rigid fixation with volar locking plates (for the extra-articular component) and arthroscopic control of the reduction (for the articular component). It is important that the operation be carried out using the dry arthroscopic technique. However, arthroscopy is just an addition to conventional methods. Thorough knowledge of and facility with classic techniques of distal radius fracture treatment is essential for a good result. PMID:21971058

    The prevalence of ligamentous injury associated with fractures of the distal radius is reported to be as high as 69% with injury to the scapholunate interosseous ligament and lunotriquetral interosseous ligament occurring in 16% to 40% and 8.5% to 15%, respectively. There is a lack of consensus on which patients should undergo advanced imaging, arthroscopy, and treatment and whether this changes their natural history. Overall, patients with high-grade intercarpal ligament injuries are shown to have longer-term disability and sequelae compared with those with lower-grade injuries. This article reviews the diagnosis and treatment options for these injuries. PMID:26205702

    To retrospectively evaluate the diagnostic accuracy of magnetic resonance (MR) arthrography of the hip with leg traction in the evaluation of ligamentum teres lesions and to evaluate whether there is increased articular distraction, possibly indicating secondary instability, in hips with ligamentum teres injuries. Institutional review board approval and informed consent were obtained for this retrospective study. MR arthrograms of the hip with leg traction of 184 consecutive patients, including 108 men (mean age, 32.6 years; range, 19-53 years) and 76 women (mean age, 38.5 years; range, 18-56 years), who underwent hip arthroscopy were assessed for the presence of ligamentum teres lesions. The MR arthrographic findings were independently assessed by two radiologists who were blinded to the arthroscopic results. The inclusion criteria stipulated no previous surgery, arthroscopy within 1 month after MR arthrography, and availability of a detailed surgical report with ligamentum teres findings. The arthroscopy findings served as the reference standard. Sensitivity, specificity, accuracy, and K statistics for interobserver and intraobserver agreement were calculated. At arthroscopy, 32 ligamentum teres injuries were found. The ligamentum teres was normal in 152 (82.6 %) patients and had suffered low-grade partial tears in 15 (8.1 %) patients, high-grade partial tears in 10 (5.4 %) patients, and complete ruptures in 7 (3.8 %) patients. MR arthrography with axial traction demonstrated moderate sensitivity and high specificity for both low-grade (62/93 %) and high-grade (66/96 %) partial tears. Grouping low- and high-grade partial tears increased the diagnostic performance of MR arthrography, yielding a sensitivity of 87 % and a specificity of 95 %. For complete ligamentum teres tears, MR arthrography with leg traction demonstrated high sensitivity (92 %) and specificity (98 %). Articular distraction was significantly increased in patients with complete ruptures of the

    Twenty-three patients have been examined by NMR imaging for osteochondritis dissecans of the knee joint, eight of them prior to surgery, and fifteen for post-surgery follow-up control after refixation or bone cartilage grafting. A 1.5 Tesla magnetom with a flat surface coil has been used. The morphology of the different stages observed in the NMR images is explained, and the findings are compared with the results obtained by other methods. NMR imaging is shown to be the best method especially for follow-up controls after refixation or bone cartilage grafting, so that arthroscopy for control purposes can be limited to therapeutical indications.

    Full Text Available Background: Factors influencing publication of manuscripts in reputed journals have never been studied to the best of our knowledge. This study was conducted to evaluate the trend in publication within the Indian Journal of Orthopaedics (IJO. Materials and Methods: A cross-sectional study was conducted by accessing the online database of the IJO. All the issues available online were included. Published articles were classified into one of the following thirteen categories: (i Basic Sciences (ii trauma (upper limb and lower limb (iii infections (iv pediatric orthopedics (v arthroplasty (vi arthroscopy (vii spine surgery (viii musculoskeletal oncology (ix hand and microvascular surgery (x adult reconstruction (including the Ilizarov technique (xi general orthopedics and miscellaneous (xii letter to editor (xiii book review. A scatter diagram was plotted to study the individual trends. Results: A total of 2213 articles from 110 issues published between 1967 and 2014 were studied. Total number of articles per issue have increased over the years. Publications in the fields of trauma, adult reconstruction, arthroscopy and hand and microvascular surgery have increased steadily. Arthroplasty and spine surgery have recorded dramatic increase in publication. On the other hand, publications in the rest of the fields have declined of which the greatest fall is noted in the field of musculoskeletal oncology. Conclusions: Trend in publication with the IJO has changed over years with more articles being published in arthroplasty and Spine surgery. Despite advances, publication in the field of musculoskeletal oncology has fallen.

    This report describes the treatment of 2 cases of full-thickness cartilage defect of the femoral head. The authors performed osteochondral autologous transplantation with a different technique that has not been reported to date. One patient was 37 years old, and the other was 42 years old. Both presented with hip pain. In both patients, radiograph and magnetic resonance imaging scan showed a focal chondral defect on the weight-bearing area of the femoral head and acetabular impingement. A retrograde osteochondral autologous transplantation technique combined with hip arthroscopy and arthroscopic impingement treatment was performed. After a 2-month recovery period, the symptoms were resolved. In the first year of follow-up, Harris Hip scores improved significantly (case 1, 56.6 to 87.6; case 2, 58.6 to 90). The technique described yielded good short- and midterm clinical and radiologic outcomes. To the authors' knowledge, this report is the first to describe a retrograde osteochondral transplantation technique performed with hip arthroscopy in the femoral head. PMID:24972445

    A prospective study was performed on 101 patients who underwent an arthroscopic anterior cruciate ligament (ACL) reconstruction with fresh-frozen patellar tendon allograft (bone-patellar tendon-bone). We present the results of the first 60 patients with a minimum follow-up of 2 years. Thirty-four were men and 26 women with a mean age of 23. In 45 patients, a postoperative arthroscopy was performed, and tissue biopsies of the reconstructed ACL were obtained. Patients were evaluated according to the International Knee Documentation Committee evaluation form. After a mean follow-up of 47 months, the overall results were normal or nearly normal in 85%. Under postoperative arthroscopy, the macroscopic appearance of the implant was similar to that of a normal ligament. The ACL allograft was covered with a normal, well-vascularized synovium. There were no cases of infection, disease transmission or tissue rejection. We conclude that the use of fresh-frozen patellar tendon allografts is a good method of ACL reconstruction.

    To assess diagnostic performance of traction MR arthrography of the hip in detection and grading of chondral and labral lesions with arthroscopic comparison. Seventy-five MR arthrograms obtained ± traction of 73 consecutive patients (mean age, 34.5 years; range, 14-54 years) who underwent arthroscopy were included. Traction technique included weight-adapted traction (15-23 kg), a supporting plate for the contralateral leg, and intra-articular injection of 18-27 ml (local anaesthetic and contrast agent). Patients reported on neuropraxia and on pain. Two blinded readers independently assessed femoroacetabular cartilage and labrum lesions which were correlated with arthroscopy. Interobserver agreement was calculated using κ values. Joint distraction ± traction was evaluated in consensus. No procedure had to be stopped. There were no cases of neuropraxia. Accuracy for detection of labral lesions was 92 %/93 %, 91 %/83 % for acetabular lesions, and 92 %/88 % for femoral cartilage lesions for reader 1/reader 2, respectively. Interobserver agreement was moderate (κ = 0.58) for grading of labrum lesions and substantial (κ = 0.7, κ = 0.68) for grading of acetabular and femoral cartilage lesions. Joint distraction was achieved in 72/75 and 14/75 hips with/without traction, respectively. Traction MR arthrography safely enabled accurate detection and grading of labral and chondral lesions.

    Bucket handle lesions are vertical longitudinal tears in the meniscus that may displace centrally into the respective medial or lateral compartment, frequently causing mechanical symptoms, including pain, perceived instability, and mechanical locking. Bucket handle meniscal tears are most commonly from a traumatic etiology and are frequently found with concomitant anterior cruciate ligament (ACL) injuries. Multiple imaging signs and associations have been described for the diagnosis of bucket handle meniscus tears, including coronal truncation, absent bow tie sign, double posterior cruciate ligament (PCL), double ACL, displacement of the bucket handle fragment, and disproportionate posterior horn signs. Among meniscal pathology encountered on magnetic resonance imaging or during arthroscopy, bucket handle meniscal tears are infrequent occurrences. Furthermore, the occurrence of displaced medial and lateral bucket handle tears found on imaging and during arthroscopy is very uncommon and is only sparsely reported in the literature. When displaced medial and lateral bucket handle meniscal segments are visualized within the intercondylar notch along with the ACL and PCL, the radiologic findings are referred to as the "quadruple cruciate" sign or the "Jack and Jill lesion." Of the few case reports described in the literature, only one noted displaced medial and lateral bucket handle meniscus tears with an intact ACL and PCL. The current case report outlines a similar rare case of the quadruple cruciate sign: displaced medial and lateral bucket handle meniscal tears located within the intercondylar notch and an intact ACL and PCL.

    To investigate the direct effect to the cartilage caused by the meniscal repair, we examined patients who underwent an isolated meniscal repair without any other abnormalities by arthroscopic examination. A total of 17 patients were examined by second-look arthroscopy after an average interval of 9 months from the meniscal repair, and have been evaluated the status of the repaired meniscus and of the relative femoral condylar cartilage. Changes in the severity of the cartilage lesion between at the time of meniscal repair and the time of the second-look arthroscopy were considered based on the status of the repaired meniscus. Regardless of the healing status of the repair site, it was possible to prevent degeneration in the cartilage in 9 of the 10 patients who demonstrated no degeneration in the meniscal body. Of the 7 patients who demonstrated degeneration in the meniscal body, progression in cartilage degeneration was noted as 1 grade in 2 patients and 2 grades in another 3 patients. Even in those in which stable fusion of the repair site was achieved, the condition of the inner meniscal body was not necessarily maintained favorably in all cases, indicating that degeneration in the meniscal body was a risk factor for cartilage degeneration. It was concluded that recovery could not be expected even at 9 months after the repair if the lesion had already demonstrated degeneration in the meniscal body at the time of repair.

    Objectives: In the present work, we aim to identify changes in the cartilage texture of the injured knee in young, physically active, patients by computer analysis of MRI images based on 3.0 T morphological sequences. Methods: Fifty-three young patients with training injury or trauma in one knee underwent MRI and arthroscopy. Textural features were computed from the MRI images of the knee-cartilages and two classes were formed of 28 normal and 16 with pathology only in the medial femoral condyle (MFC) cartilage. Results: Textural features with statistically significant differences between the two classes were found only at the MFC and the medial tibial condyle (MTC) areas. Three features-combinations, at the MFC or the MTC, maximized the between classes separation, thus, rendering alterations in cartilage texture due to injury more evident. The MFC cartilage in the pathology class was found more inhomogeneous in the distribution of gray-levels and of lower texture anisotropy and the opposed MTC cartilage, though normal on MRI and arthroscopy, was found to have lower texture anisotropy than cartilage in the normal class. Conclusion: Texture analysis may be used as an adjunct to morphological MR imaging for improving the detection of subtle cartilage changes and contributes to early therapeutic approach.

    Objective To compare the diagnostic performance of the three-dimensional turbo spin-echo (3D TSE) magnetic resonance imaging (MRI) technique with the performance of the standard two-dimensional turbo spin-echo (2D TSE) protocol at 1.5 T, in the detection of meniscal and ligament tears. Materials and Methods Thirty-eight patients were imaged twice, first with a standard multiplanar 2D TSE MR technique, and then with a 3D TSE technique, both in the same 1.5 T MRI scanner. The patients underwent knee arthroscopy within the first three days after the MRI. Using arthroscopy as the reference standard, we determined the diagnostic performance and agreement. Results For detecting anterior cruciate ligament tears, the 3D TSE and routine 2D TSE techniques showed similar values for sensitivity (93% and 93%, respectively) and specificity (80% and 85%, respectively). For detecting medial meniscal tears, the two techniques also had similar sensitivity (85% and 83%, respectively) and specificity (68% and 71%, respectively). In addition, for detecting lateral meniscal tears, the two techniques had similar sensitivity (58% and 54%, respectively) and specificity (82% and 92%, respectively). There was a substantial to almost perfect intraobserver and interobserver agreement when comparing the readings for both techniques. Conclusion The 3D TSE technique has a diagnostic performance similar to that of the routine 2D TSE protocol for detecting meniscal and anterior cruciate ligament tears at 1.5 T, with the advantage of faster acquisition.

    Full Text Available BACKGROUND: Many different methods have been used in an effort to provide adequate analgesia after knee arthroscopic surgery. In this study analgesic effect of intra-articular fentanyl, pethidine and dexamethasone was compared. METHODS: In a double blind randomized study 48 male patients undergoing knee arthroscopic meniscectomy were allocated to groups receiving intra-articular fentanyl 50 µg or pethidine 20 mg or dexamethasone 8 mg at the end of arthroscopy during general aesthesia. Postoperative pain scores using visual analogue scale were measured and also analgesic requirements and the time of ability to walk were recorded. RESULTS: Pain scores at one, two, six and 24 h after intra-articular injection were not significantly different for fentanyl and pethidine but were higher significantly for dexamethasone at all four mentioned times. The mean average time of ability to walk was significantly longer for dexamethasone. The analgesic requirements during the first 24 h after intraarticular injection were significantly greater only for dexamethasone too. CONCLUSION: Better postoperative analgesia, less pain score and shorter time to walk were achieved by fentanyl and pethidine in comparison to dexamethasone but the results were not significantly different between fentanyl group and pethidine. KEYWORDS: Arthroscopy, opioid, pain.

    Full Text Available : In today’s world high velocity road traffic accidents, sports activities and increased fitness awareness, ACL injuries is a common clinical problem. Once upon a time ACL rupture led to a relatively safe existence and was thought to be of less significance. Now with improved knee kinematics and clinical skills, it has been established that post ACL injury, the prevalence of clinically significant meniscal damage increases with time and is associated with increasing disability and arthrosis. Ligament reconstruction has not been shown to prevent arthrosis, but studies show that it appears to reduce the risk of subsequent meniscal injury and improve anteroposterior knee motion and facilitates return to high level sporting activities. As surgical techniques like Arthroscopy improve the ability to tackle complex problems, complex decisions regarding Meniscal repair and transplantation, Cartilage repair and regeneration are now commonplace, as are decisions regarding the need for Osteotomies in Arthritically unstable knees. Arthroscopic reconstruction of the Anterior Cruciate Ligament with patellar bone - tendon - bone graft is minimally invasive and is relatively quick and simple to perform, although attention to detail as required for good results. Thus arthroscopy helps in diagnosis and treatment of internal derangement and on extra articular reconstruction.

    In this study the use of the high resolution Micro-Single Photon Emission Tomography (HiSPECT) system with a radioactive bonemarker, (99m)Tc-oxidronate, was evaluated in dogs with coronoid pathology and/or flexor enthesopathy. Sixty-five elbows of 34 dogs were included. CT and HiSPECT were performed on all elbows, arthroscopy on 59. Tracer uptake in 8 anatomical regions was graded according to two models. Increased activity in the medial epicondylar region was associated with flexor pathology on CT (P=0.0002) and arthroscopy (P<0.0001) and increased uptake in the medial coronoid (P<0.0001) and the medial condylar area (P<0.013) with coronoid pathology. Uptake in the remaining areas was not associated with both pathologies. In conclusion, the improved resolution of the HiSPECT system allows identification of increased tracer uptake in the anatomical regions involved in coronoid pathology and flexor enthesopathy. This modality may improve the diagnostic potential of the bone scan in canine elbow disease.

    To evaluate the differential features of complete and partial-thickness tears of the posterior cruciate ligament (PCL) and to describe associated knee injuries at magnetic resonance imaging (MRI). Twenty-four subjects were studied, including 15 with complete PCL tears and 9 with partial PCL tears. The PCL status was determined at arthroscopy in all cases. Knee MRI were performed at 1.0 Tesla using a dedicated knee surface coil. Two radiologists retrospectively reviewed MR images and correlated MRI findings to results of arthroscopy. There was no statistically significant difference between complete tears and partial tears with regard to thickness, margination, and signal intensity of the PCL. However, complete tears were more likely to show focal areas of ligamentous discontinuity (13/15: 3/9, {rho} = 0.0073). Associated knee injuries were seen in 22 (92%) patients and were seen more frequently in patients with complete PCL tears, which were bony injuries (n 16, 67%), tears of the medial collateral ligament (n = 12, 50%) and menisci (n = 11, 46%), and stage III joint effusion (n = 17, 71%). The most useful MRI criteria for distinguishing complete from partial PCL tear is focal area of ligamentous discontinuity, that is complete tears are more likely to show focal areas of discontinuity, whereas partial tears are more likely to show at least some intact fibers.

    Magnetic resonance findings with clinical and arthroscopic correlation of intraligamentous cysts of the anterior cruciate ligament (ACL) are presented. Three cases of intraligamentous cysts of the ACL were identified out of 681 knee MRI examinations over a 2-year period. Arthroscopy and postoperative MRI were performed in all three patients, each of whom experienced knee pain with extreme flexion and extension. In all three cases the intraligamentous cyst was homogeneously hypointense on T1-weighted imaging and hyperintense on T2-weighted imaging relative to the ACL. Two of the three ACL cysts required a 70{degrees} scope for adequate visualization and establishment of posteromedial and posterolateral portals for arthroscopic treatment. One cyst could not be visualized arthroscopically and probing of the ACL from the anterior portal resulted in drainage of the cyst. No patient had presence of ACL cyst on follow-up MRI or recurrence of symptoms at a mean of 24 months. Intraligamentous cyst of ACL is a rare cause of knee pain. It should be suspected in patients having chronic pain with extremes of motion. Magnetic resonance findings are diagnostic and help to guide arthroscopy. 14 refs., 3 figs.

    To evaluate the diagnostic accuracy of MR imaging in posterior cruciate ligament(PCL) injuries, to describe the variety of these injuries and to assess the type and frequency of associated knee injuries. We retrospetively analysed 75 cases with knee injuries. In all cases, the presence of a PCL tear was determined by arthroscopy or surgery and the type of tear and patterns of associated knee injuries were described. Twenty-eight PCL tears were identified with arthroscopy or surgery. Figures for the sensitivity, specificity, and accuracy of MR diagnosis for the PCL injury were 86%, 94% and 91% respectively. Twenty-one cases(75%) had complete PCL tears and seven (25%) had partial tears. The commonest tear site was midsubstance(18 cases, 64.3%). Twenty-seven cases(96%) had associated knee injuries ; the remaining patient (4%) had isolated PCL injuries, There were 19 cases(68%) of ligamentous injuries, ten(36%) of meniscal tear, ten (36%) of bony injuries, and 20 (71%) of joint effusions. Of the ligamentous injuries, those involving the medial collateral ligament were most often seen(10 cases, 36%).

    Introduction: Intra-articular ganglion cysts of the knee joint are rare occurrences. They are usually encountered as incidental findings in magnetic resonance imaging (MRI), or in arthroscopy. They may originate from both the cruciate ligaments and the menisci, from the popliteus tendon and alar folds, infrapatellar fat pad of Hoffa, and subchondral bone cysts. Those arising from the Hoffa’s fat pad, usually present as palpable mass at anterior aspect of the knee joint. We report a case of intraarticular ganglion cyst of knee arising from the infrapatellar fat pad and protruding anterolaterally through retinacular rent into the subcutaneous plane. Case Report: A 19-year-old young man, presented with a painless gradually increasing swelling at the anterior aspect of left knee of 9 months duration. MRI scan revealed a multilobulated, cyst with septations within the anterior aspect of the knee joint, just inferolateral to the patella, with deep extension into the infrapatellar fat pad, and superficial extension into the subcutaneous space across the retinaculum. After diagnostic arthroscopy, we performed an open excision of the cystic mass and confirmed the retinacular rent pre-operatively. Conclusion: Arthroscopic resection and debridement is the gold standard treatment in ganglion cyst of the knee. However, a subcutaneous extension may lead to incomplete arthroscopic resection: Leaving behind the residual tissue which may cause recurrence. Therefore, proper pre-operative evaluation of MR images of these cases is very important. PMID:27299075

    Full Text Available Recently, a remnant-preserving anterior cruciate ligament (ACL reconstruction technique has been developed. However, the pre-operative condition of remnant ACL is occasionally difficult to evaluate by magnetic resonance imaging. The purpose of this study is to evaluate the accuracy of pre-operative visualization of remnant ACL using three-dimensional computed tomography (3D-CT. The remnant ACL in 25 patients was examined by 3D-CT before ACL reconstruction surgery. Findings on 3D-CT images and arthroscopy were compared. The 3D-CT images were classified into 4 groups: Group A, remnant fibers attached to the posterior cruciate ligament (PCL; Group B, those located between the PCL and the lateral wall; Group C, those attached to the lateral wall; and Group D, no identifiable remnant fibers on the tibial side. These groups were made up of 4, 3, 9 and 9 patients, respectively. Findings on 3D-CT images were identical to those during arthroscopy in 20 of 25 cases (80%. Remnant ACL can be accurately evaluated using 3D-CT in 80% of cases of torn ACL. This novel method is a useful technique for pre-operative assessment of remnant ACL.

  20. MDCT arthrography of the wrist: Diagnostic accuracy and indications

    International Nuclear Information System (INIS)

    Purpose: To evaluate the diagnostic accuracy and indications of arthrography with Multidetector Computed Tomography (arthro-MDCT) of the wrist in patients with absolute or relative contraindications to magnetic resonance imaging (MRI) studies and in patients with periarticular metal implants using diagnostic arthroscopy as the gold standard. Materials and methods: After intra-articular injection of iodixanol and volumetric acquisition, 43 wrists in patients of both genders (18 females, 25 males, age range 32-60 years) were examined with a 16-detector-row CT scanner. Fifteen patients had prior wrist surgery. The patients had arthralgia, degenerative and traumatic arthropathies as well as limited range of motion, but no radiologically detected fractures. All examinations were interpreted by two experienced musculoskeletal radiologists. The findings were compared with arthroscopic findings carried out within 28 days of the CT study. Results: In non-operated and operated wrists the comparison between arthro-MDCT and arthroscopy showed sensitivity, specificity and accuracy ranging between 92% and 94% for triangular fibrocartilage complex (TFCC), between 80% and 100% for intrinsic ligaments located within the proximal carpal compartment, and between 94% and 100% for articular cartilage. Inter-observer agreement between two radiologists, in the evaluation of all types of lesions, was almost perfect (k = 0.96) and statistically significant (p < 0.05). Conclusions: Arthro-MDCT of the wrist provides an accurate diagnosis to identify chondral, fibrocartilaginous and intra-articular ligament lesions in patients who cannot be evaluated by MRI, and in post-surgical patients.

  1. Patella Dislocation with Vertical Axis Rotation: The “Dorsal Fin” Patella

    A 44-year-old woman presented following minor trauma to her right knee. While dancing she externally rotated around a planted foot and felt sudden pain in her right knee. She presented with her knee locked in extension with a “dorsal fin” appearance of the soft tissues tented over the patella. This was diagnosed as a rare case of an intraarticular patella dislocation, which was rotated 90 degrees about the vertical axis. Closed reduction in the emergency room was unsuccessful but was achieved in theatre under general anaesthetic with muscle relaxation. Postreduction arthroscopy demonstrated that no osteochondral or soft tissue damage to the knee had been sustained. In patients presenting with a knee locked in extension with tenting of skin over the patella (the “dorsal fin” appearance), intra-articular patella dislocation should be suspected. Attempts to reduce vertical patella dislocations under sedation with excessive force or repeatedly without success should be avoided to prevent unnecessary damage to the patellofemoral joint. In this clinical situation we recommend closed reduction under general anaesthetic followed by immediate knee arthroscopy under the same anaesthetic to ensure that there is no chondral damage to the patella or femoral trochlea and to rule out an osteochondral fracture.

    Purpose: To evaluate the diagnostic accuracy and indications of arthrography with Multidetector Computed Tomography (arthro-MDCT) of the wrist in patients with absolute or relative contraindications to magnetic resonance imaging (MRI) studies and in patients with periarticular metal implants using diagnostic arthroscopy as the gold standard. Materials and methods: After intra-articular injection of iodixanol and volumetric acquisition, 43 wrists in patients of both genders (18 females, 25 males, age range 32-60 years) were examined with a 16-detector-row CT scanner. Fifteen patients had prior wrist surgery. The patients had arthralgia, degenerative and traumatic arthropathies as well as limited range of motion, but no radiologically detected fractures. All examinations were interpreted by two experienced musculoskeletal radiologists. The findings were compared with arthroscopic findings carried out within 28 days of the CT study. Results: In non-operated and operated wrists the comparison between arthro-MDCT and arthroscopy showed sensitivity, specificity and accuracy ranging between 92% and 94% for triangular fibrocartilage complex (TFCC), between 80% and 100% for intrinsic ligaments located within the proximal carpal compartment, and between 94% and 100% for articular cartilage. Inter-observer agreement between two radiologists, in the evaluation of all types of lesions, was almost perfect (k = 0.96) and statistically significant (p < 0.05). Conclusions: Arthro-MDCT of the wrist provides an accurate diagnosis to identify chondral, fibrocartilaginous and intra-articular ligament lesions in patients who cannot be evaluated by MRI, and in post-surgical patients.

    Full Text Available This prospective randomised clinical trial evaluated the effect of warmed irrigation fluid on body temperature in anaesthetised dogs undergoing arthroscopic elbow surgery. Nineteen dogs undergoing elbow arthroscopy were included in the study and were randomly allocated to one of two groups. Group RT received irrigation fluid at room temperature (RT while dogs in group W received warmed (W irrigation fluid (36oC. A standardised patient management and anaesthetic protocol was used and body temperature was measured at four time points; (T1 pre-anaesthetic examination, (T2 arrival into theatre, (T3 end of surgery and (T4 arrival into recovery. There was no significant difference in body temperature at any time point between the groups. The mean overall decrease in body temperature between pre-anaesthetic examination (T1 and return to the recovery suite (T4 was significant in both groups, with a fall of 1.06±0.58oC (p<0.001 in group RT and 1.53±0.76oC (p<0.001 group W. There was no significant difference between the groups. At the end of surgery (T3 4/19 (21.1% of dogs were hypothermic (<37oC. The addition of warmed irrigation fluids to a temperature management protocol in dogs undergoing elbow arthroscopy during general anaesthesia did not lead to decreased temperature losses.

    The purpose of this study was to determine inter- and intraobserver variability of MR arthrography of the shoulder in the detection and classification of superior labral anterior posterior (SLAP) lesions. MR arthrograms of 78 patients who underwent MR arthrography before arthroscopy were retrospectively analysed by three blinded readers for the presence and type of SLAP lesions. MR arthrograms were reviewed twice by each reader with a time interval of 4 months between the two readings. Inter- and intraobserver agreement for detection and classification of SLAP lesions were calculated using {kappa} coefficients. Arthroscopy confirmed 48 SLAP lesions: type I (n = 4), type II (n = 37), type III (n = 3), type IV (n = 4). Sensitivity and specificity for detecting SLAP lesions with MR arthrography for each reader were 88.6%/93.3%, 90.9%/80.0% and 86.4%/76.7%. MR arthrographic and arthroscopic grading were concurrent for 72.7%, 68.2% and 70.5% of SLAP lesions for readers 1-3, respectively. Interobserver agreement was excellent ({kappa} = 0.82) for detection and substantial ({kappa} = 0.63) for classification of SLAP lesions. For each reader intraobserver agreement was excellent for detection ({kappa} = 0.93, {kappa} = 0.97, {kappa} = 0.97) and classification ({kappa} = 0.94, {kappa} = 0.84, {kappa} = 0.93) of SLAP lesions. MR arthrography allows reliable and accurate detection of SLAP lesions. In addition, SLAP lesions can be diagnosed and classified with substantial to excellent inter- and intraobserver agreement.

    Since its inception, arthroscopic surgery has become widely adopted among orthopedic surgeons. It is therefore important to have an understanding of the basic principles of arthroscopy. Compared with open techniques, arthroscopic procedures are associated with smaller incisions, less structural damage, improved intra-articular visualization, less pain in the immediate postoperative period, and faster recovery for patients. Pump systems used for arthroscopic surgery have evolved over the years to provide improved intraoperative visualization. Gravity flow systems were described first and are still commonly used today. More recently, automated pump systems with pressure or dual pressure and volume control have been developed. The advantages of automated irrigation systems over gravity irrigation include a more consistent flow, a greater degree of joint distention, improved visualization especially with motorized instrumentation, decreased need for tourniquet use, a tamponade effect on bleeding, and decreased operative time. Disadvantages include the need for additional equipment with increased cost and maintenance, the initial learning curve for the surgical team, and increased risk of extra-articular fluid dissection and associated complications such as compartment syndrome. As image quality and pump systems improve, so does the list of indications including diagnostic and treatment modalities to address intra-articular pathology of the knee, shoulder, hip, wrist, elbow, and ankle joints. This article reviews the current literature and presents the history of arthroscopy, basic science of pressure and flow, types of irrigation pumps and their functions, settings, applications, and complications.

    Full Text Available A 44-year-old woman presented following minor trauma to her right knee. While dancing she externally rotated around a planted foot and felt sudden pain in her right knee. She presented with her knee locked in extension with a “dorsal fin” appearance of the soft tissues tented over the patella. This was diagnosed as a rare case of an intraarticular patella dislocation, which was rotated 90 degrees about the vertical axis. Closed reduction in the emergency room was unsuccessful but was achieved in theatre under general anaesthetic with muscle relaxation. Postreduction arthroscopy demonstrated that no osteochondral or soft tissue damage to the knee had been sustained. In patients presenting with a knee locked in extension with tenting of skin over the patella (the “dorsal fin” appearance, intra-articular patella dislocation should be suspected. Attempts to reduce vertical patella dislocations under sedation with excessive force or repeatedly without success should be avoided to prevent unnecessary damage to the patellofemoral joint. In this clinical situation we recommend closed reduction under general anaesthetic followed by immediate knee arthroscopy under the same anaesthetic to ensure that there is no chondral damage to the patella or femoral trochlea and to rule out an osteochondral fracture.

  7. Texture analysis of articular cartilage traumatic changes in the knee calculated from morphological 3.0 T MR imaging

    International Nuclear Information System (INIS)

    Objectives: In the present work, we aim to identify changes in the cartilage texture of the injured knee in young, physically active, patients by computer analysis of MRI images based on 3.0 T morphological sequences. Methods: Fifty-three young patients with training injury or trauma in one knee underwent MRI and arthroscopy. Textural features were computed from the MRI images of the knee-cartilages and two classes were formed of 28 normal and 16 with pathology only in the medial femoral condyle (MFC) cartilage. Results: Textural features with statistically significant differences between the two classes were found only at the MFC and the medial tibial condyle (MTC) areas. Three features-combinations, at the MFC or the MTC, maximized the between classes separation, thus, rendering alterations in cartilage texture due to injury more evident. The MFC cartilage in the pathology class was found more inhomogeneous in the distribution of gray-levels and of lower texture anisotropy and the opposed MTC cartilage, though normal on MRI and arthroscopy, was found to have lower texture anisotropy than cartilage in the normal class. Conclusion: Texture analysis may be used as an adjunct to morphological MR imaging for improving the detection of subtle cartilage changes and contributes to early therapeutic approach

    Full Text Available Mainly by a limited access to new techniques and technologies, veterinary medicine in developing countries, has been far behind from the human medicine. One of the causes is the limited access to technology and specific techniques. Moreover, it is clear that many new technologies have proven their benefits in the two disciplines, making necessary and almost mandatory their massive implementation in humans and animals. The possibility to use human elements for veterinary techniques would improve the technology access and veterinarians training, at lower costs. The purpose of this study is to verify the feasibility to perform a knee arthroscopy in dogs with small human joints arthroscopic lenses. Under protocols established in veterinary 12 knee arthroscopies were performed in canine cadaver, using a wrist and ankle arthroscope human of 2.4 mm in diameter and 30° of angulation. All the structures reported in the literature were possible to visualize using a 2.4 mm arthroscope. In this sense, it is possible to develop training activities and subsequent implementation of endoscopic techniques in canine femorotibiopatellar joint, using a lens of small joints of human medicine.

    A prospective study was performed on 101 patients who underwent an arthroscopic anterior cruciate ligament (ACL) reconstruction with fresh-frozen patellar tendon allograft (bone-patellar tendon-bone). We present the results of the first 60 patients with a minimum follow-up of 2 years. Thirty-four were men and 26 women with a mean age of 23. In 45 patients, a postoperative arthroscopy was performed, and tissue biopsies of the reconstructed ACL were obtained. Patients were evaluated according to the International Knee Documentation Committee evaluation form. After a mean follow-up of 47 months, the overall results were normal or nearly normal in 85%. Under postoperative arthroscopy, the macroscopic appearance of the implant was similar to that of a normal ligament. The ACL allograft was covered with a normal, well-vascularized synovium. There were no cases of infection, disease transmission or tissue rejection. We conclude that the use of fresh-frozen patellar tendon allografts is a good method of ACL reconstruction. PMID:8961227

    Full Text Available BACKGROUND AND INTRODUCTION: Management of tibial plateau fractures had witnessed tremendous improvement in surgical techniques over the past decades. Conservative treatment of these fractures results in consistently poor results. The present literature supports that absolute anatomi cal reduction and stable fixation of peri articular fractures followed by early post - operative rehabilitation is crucial for good results. And if this is achieved by minimal damage to soft tissue the results are much better. In this study it is achieved by arthroscopy and fluoroscopy. MATERIALS AND METHODS: We have conducted a prospective study between September 2009 to august 2013 including 9 patients with tibial plateau fractures treated with combined arthroscopic and fluoroscopic reduction and internal f ixation with or without bone grafting. And then the radiographic and functional evaluation done. RESULTS: According to Hohl’s clinical and radiographic scoring systems 4 patients were assessed excellent, 3 good, 2 fair. According to Rasmussen’s clinical sc oring system 4 patients excellent, 3 good and 2 fair results. CONCLUSION: The use of arthroscopy and fluoroscopy in the management of tibial plateau fractures results in good outcome. It also helped to simultaneously treat the meniscal injuries. But its use is mainly limited to Shatzkar type1, 2, 3, 4

    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.

    To investigate the diagnostic accuracy of oblique axial intermediate weighting MR imaging in detecting partial thickness anterior cruciate ligament (ACL) bundle tears. The study protocol was approved by the institutional ethics committee. Sixty-one subjects (43 male, 18 female; mean age 27.4 years; range 9 to 57 years) with clinically suspected ACL tear or meniscal tear between September 2009 and January 2011 were studied with MRI and arthroscopy. Detection of partial tear for the ACL as a whole and for each ACL bundle by protocol A (standard orthogonal sequences) and protocol B (standard orthogonal sequences plus oblique axial intermediate weighted imaging) was compared in a blinded fashion. Performance characteristics for protocol A and protocol B were compared using sensitivity, specificity, accuracy and ROC curves. A two-tailed p value of <0.05 indicated statistical significance. Fifteen (24.6%) normal, 15 (24.6%) partial and 31 complete tears were diagnosed by arthroscopy. Sensitivity, specificity and accuracy of protocol A for the diagnosis of partial tear of the ACL was 33%, 87% and 74%, while for protocol B the values were 87%, 87% and 87% respectively. The area under the curve (AUC) for the diagnosis of partial ACL tear and individual bundle tear was higher for protocol B, although this difference did not reach statistical significance (p > 0.05). The addition of oblique axial imaging to standard MR imaging improves diagnostic accuracy for detecting partial tears of the ACL as well as individual bundle tears of the ACL. (orig.)

    Diagnosis of intra-articular lesions in children based on clinical examination and MRI is particularly challenging. To evaluate the diagnostic performance of MRI and pre-surgical evaluation of the knee in pediatric patients relative to arthroscopic evaluation as the gold standard. We report diagnoses frequently missed or inaccurately diagnosed pre-operatively. We conducted a retrospective review of MRI and pre-surgical evaluation in children and adolescents ages 1-17 years who were treated by knee arthroscopy during a 21/2-year period. All MRIs were reviewed by a pediatric radiologist blinded to clinical findings. Pediatric orthopedic clinic notes were reviewed for pre-surgical evaluation (based on physical exam, radiograph, MR images and radiologist's MRI report). Arthroscopic findings were used as the gold standard. We calculated the percentages of diagnoses at arthroscopy missed on both MRI and pre-surgical evaluation. Diagnostic accuracy between children and adolescents and in patients with one pathological lesion vs. those with >1 lesion was analyzed. We performed a second review of MR images of the missed or over-called MRI diagnoses with knowledge of arthroscopic findings. We included 178 children and adolescents. The most common diagnoses missed on MRI or pre-surgical evaluation but found at arthroscopy were: discoid meniscus (8/30, or 26.7% of cases); lateral meniscal tears (15/80, or 18.8% of cases); intra-articular loose bodies (5/36, or 13.9% of cases), and osteochondral injuries (9/73, or 12.3% of cases). Overall diagnostic accuracy of MRI and pre-surgical evaluation was 92.7% and 95.3%, respectively. No significant difference in diagnostic accuracy between children and adolescents was observed. When multiple intra-articular lesions were present, lateral meniscal tears were more likely to be inaccurately diagnosed (missed or over-called) on both MRI (P = 0.009) and pre-surgical evaluation (P < 0.001). Overall diagnostic accuracy of MRI and pre

    Patients with haemarthros of the knee were examined by MRI and arthroscopy to identify the bleeding source and to determine surgical or conservative therapy. A prospective study was performed on 120 patients who underwent MRI and arthroscopy, point lesions and bleeding sources were documented separately on a standardised form. Arthroscopy demonstrated a ruptured anterior cruciate ligament in 86%, meniscal tears in 55%, disruption of collateral ligaments in 17%, osteochondral lesions in 5% and tears of capsule or plicae in 13%. Disruption of cruciate ligaments caused haemorrhage in all but three cases. In contrast, only meniscal tears located very adjacent to the meniscal basement had bled. Those types of osteochondral lesions caused haemorrhage characterised on MRI by destruction of the subchondral plate and overlying cartilage. Severe lesions of the knee were diagnosed by MRI in 71% to 100%, slight lesions in 13% to 40% of the cases. Single, combined and bland lesions were accurately diagnosed in MRI which permitted a correct prediction of surgical and conservative therapy in 96% and 80%. Morphological criteria in MRI permit identification of bleeding sources in haemarthros of the knee. Different lesion patterns can be separated for the planning of therapy. (orig.)

    Assess the diagnostic accuracy of 3-T indirect magnetic resonance arthrography (iMRA) for hip cartilage and labral pathology detection using arthroscopy as the reference standard and compare it to the published performance of direct magnetic resonance arthrography (dMRA). Between 2009 and 2011, 290 patients suspected of having femoroacetabular impingement underwent iMRA. Our study group consisted of 41 of these patients (17 males, mean age 35 years; 24 females, mean age 33 years) who did not have a prior history of hip surgery and who subsequently underwent arthroscopy. Two experienced musculoskeletal radiologists separately evaluated the randomized and anonymized studies for the presence and quadrant location of labral and cartilage pathology. These recorded data were compared to arthroscopic reports. Forty-one patients had labral pathology, 34 patients had acetabular and 5 patients had femoral cartilage pathology at arthroscopy. Sensitivity, specificity, accuracy, negative- and positive-predictive values for labral lesion detection were respectively 98, 99, 99, 99 and 98 %; for acetabular cartilage lesion detection they were 69, 98, 89, 87 and 95 %; for femoral cartilage lesion detection they were 69, 95, 93 and 39 %. Sensitivities of iMRA by quadrant (anteroinferior, anterosuperior, posteroinferior, posterosuperior) for the labrum were 100.0, 95.0, NA and 85.7 %, for acetabular cartilage were NA, 58.8, NA and 39.5 % and for femoral cartilage were 50.0, 33.3, 75.0 and 75.0 %. NA indicates results not available because of the absence of findings in those quadrants. Specificities of iMRA by quadrant (anteroinferior, anterosuperior, posteroinferior, posterosuperior) for the labrum (95.0, 100.0, 95.1, 67.5 %), acetabular (100.0, 85.7, 92.6, 79.5 %) and femoral cartilage (100.0, 94.7, 96.2, 85.9 %). iMRA at 3 T is accurate in detecting labral pathology suggesting that it is a viable alternative to dMRA.

The most common diagnoses missed on MRI or pre-surgical evaluation but found at arthroscopy were: discoid meniscus (8/30, or 26.7% of cases); lateral meniscal tears (15/80, or 18.8% of cases); intra-articular loose bodies (5/36, or 13.9% of cases), and osteochondral injuries (9/73, or 12.3% of cases). Overall diagnostic accuracy of MRI and pre-surgical evaluation was 92.7% and 95.3%, respectively. No significant difference in diagnostic accuracy between children and adolescents was observed. When multiple intra-articular lesions were present, lateral meniscal tears were more likely to be inaccurately diagnosed (missed or over-called) on both MRI (P = 0.009) and pre-surgical evaluation (P < 0.001). Overall diagnostic accuracy of MRI and pre

  19. Anterior labral tear: diagnostic value of MR arthrography of the shoulder

    To assess the accuracy of magnetic resonance(MR) arthrography in the diagnosis of anterior labral tear of the shoulder Between september 1996 and February 2000, MR arthrography of the shoulder was performed in 281 patients with a history of shoulder pain or instability. Among this total, only 157 shoulders in 154 patients who underwent arthroscopy or open surgery 0 to 230 (average, 20.9) days after MR arthrography were included in this study; the subjects comprised of 150 males and 4 females with an average age of 23.3 years. MR arthrographs of these 154 patients were analyzed for the presence of anterior labral tears, and the findings were correlated with the arthroscopic and surgical findings. Anterior labral tear was classified as A to D according to its location, as determined by arthroscopy and surgery. (A=4 to 6 o'clock direction, anteroinferior; B=2 to 4 o'clock direction, central; C=12 to 2 o'clock direction, anterosuperior; D= SLAP lesion). The retrospective analysis of MR arthrographs showing false-positive and negative findings was also underthken.. In the diagnosis of anterior labral tear, MR arthrography showed a sensitivity of 94%, a specificity of 90% and an accuracy of 91%. Anterior labral tears were confirmed by arthroscopy or surgery in 62 of the 157 shoulders (39%). Among 62 lesion, two (3%) were observed in area A, 32(52%) in area A+B, nine (15%) in area A+B+C, one(2%) in area A+B+D,13(21%) in area A+B+C+D, two (3%) in area B+C, one(2%) in area B+D, and two(3%) in area C. Among ten false-positive cases, seven were focal lessions (two, three and two lesions in area A, B and C, respectively), and in the remaining three cases, lacated in area A+B, MR arthrography revealed thickening and deformation. All four false negatives were focal lesions (two in area A and two in area C). Other than in focal lesions, in which accuracy was relatively low, MR arthrography showed high sensitivity, specificity and accuracy in the diagnosis of anterior labral tear

    Full Text Available Avascular necrosis is frequently associated with femoral head involvement and may also be observed in the knee joint, humeral head, wrist and foot. Avascular necrosis may also affect multiple joints. Bilateral involvement of both humeral and femoral heads is a rare condition in the same patient. A patient who complained about a sustained pain in both of his shoulders and hips for a few years applied to our outpatient clinic. The patient who had oral steroid treatment episodically was diagnosed with ulcerative colitis seven years ago. Arthroscopy-assisted decompression to the shoulder joints and core decompression to both hip joints were applied. The range of motions of both humeral and femoral joints was limited and painful prior to the surgical treatment. A follow-up after five years later showed that the patient's range of motions of joints was normal and no further treatment was necessary. [Arch Clin Exp Surg 2013; 2(4.000: 246-250
