Purpose: This study aimed to assess the accuracy of MRI in identifying ulnar collateral ligament (UCL), radial collateral ligament (RCL), and volar plate (VP) injuries of the metacarpophalangeal joint (MCPJ) of the thumb by comparing with diagnostic arthroscopy. Methods: A total of 56 consecutive patients (56 thumbs) who underwent arthroscopy of MCPJ of thumb were enrolled. MRI findings reviewed by consensus reading of two blinded radiologists were compared with arthroscopic examination. Statistical data, including sensitivity, specificity, accuracy, were analyzed. Additionally, the performance characteristics between 3.0-tesla (39 thumbs) and 1.5-tesla (17 thumbs) MRI and acute (≤4 weeks after injury) and chronic (>4 weeks) injuries were compared. Results: Of the 56 thumbs, 38 thumbs (67.9%) showed complete correspondence between MRI and arthroscopic findings. The sensitivity, specificity and accuracy of MRI for detecting UCL injuries were 78.8%, 87.0%, and 82.1%, respectively. The sensitivity, specificity and accuracy of MRI for detecting RCL injuries were 85.7%, 91.4%, and 85.7%, respectively. The sensitivity, specificity, and accuracy of MRI for detecting VP injuries were 89.5%, 89.2%, and 81.0%, respectively. 3.0-tesla MRI showed higher correspondence with arthroscopic observation (76.9%) than 1.5-tesla MRI (47.1%) (p = 0.028). For acute injuries, 78.4% showed complete correspondence between MRI and arthroscopic findings, whereas 47.4% with chronic injuries revealed complete agreement (p = 0.019). Conclusion: Overall, MRI is moderately effective in evaluating ligamentous lesions around MCPJ of thumb, but MRI is more sensitive in diagnosing acute injuries. Furthermore, 3.0-tesla MRI can provide results with better accuracy for diagnosing ligamentous lesions around MCPJ of thumb. However, the sensitivity and the specificity are not applicable to all ligament injuries, but only the severe one which would agree for surgical options.

Purpose: The aim of this study is to access the correlation of Moragas manouver and arthroscopic findings, in the diagnosis of lateral meniscal injury, and to know the imagenologic findings and comparison with arthroscopic results. Methods: 474 arthroscopic procedures were performed with meniscal injuries between 2005-2013. 142 are lateral meniscus lesions (male=94, female=58) by clinical evaluation, average age= 34.4 years old (15-58). MRI was performed in 73 cases, what allowed correlate findings clinical imaging. All clinical tests were realized by the same clinician. Results: Of the 142 patients, 136 were pure external meniscus injuries, (95.77%), 3 were colateral ligament lesions, 1 was a parameniscal cyst, 1 was popliteus tendinosis and 1 was normal. Of 73 cases with MRI evaluation, 68 were a pure lateral meniscal lesions (93.15%), 2 were partial colateral ligament lesions, 1 was popliteus tendinosis, 1 was iliotibial band friction syndrome and 1was lateral condyle avascular necrosis. The comparison between MRI findings and arthroscopic procedure they had no statistical significance. p< 0.0025 Conclusion: The Moragas manouver has a high sensitivity diagnosed for lateral meniscal injury, and the imagenologic correlation with arthroscopic findings was minor in this study (95.77% v/s 93.15%). Discussion: A correct clinic examination and semiologic tests are still important to clinical diagnosis in orthopedics.

Introduction: Knee injuries are common among active adults. Achieving a correct clinical diagnosis is often difficult in acute presentations. Knee arthroscopy is considered the gold standard in diagnosing post-traumatic intra-articular lesions, but it is an invasive procedure requiring a certain degree of expertise. Magnetic Resonance Imaging (MRI) is a non-invasive, sensitive diagnostic tool for knee injuries. This study aims to correlate the findings of MRI with arthroscopy of the knee. Method: This Prospective Observational Study was done at Shree Birendra Hospital, Kathmandu, Nepal from 13 Feb 2016 to 13 Jun 2016. The sensitivity, specificity, and accuracy of MRI findings in ligamentous, meniscal, and osteochondral injuries of the knee were analyzed using arthroscopic findings as standard. Result: Fifty-two patients (35 male and 17 female), mean age 35.4 years were included in the study. The accuracy of MRI for anterior cruciate ligament (ACL), posterior cruciate ligament (PCL), medial meniscus, lateral meniscus, and chondral lesions of the knee were 94%, 100%, 92%,86%, and 86% respectively. Conclusion: The MRI is accurate  (86-94%) in diagnosing Meniscal and Ligamentous injuries of the knee. It has poor sensitivity (22%) for chondral lesions.

Abstract Background Magnetic resonance imaging (MRI) has been considered the most appropriate examination for wrist ligament injuries diagnosis, but it frequently fails to assess the intrinsic ligament lesion. Therefore, wrist arthroscopy is required to enhance and define the diagnosis. Purpose We compare the MRI imaging with wrist arthroscopy for intrinsic wrist ligaments (scapholunate [SL] and lunotriquetral [LT]) and triangular fibrocartilage complex (TFCC) injuries detection. Patients and Methods From 2007 to 2014, 532 patients affected by suspected SL, LT, and TFCC posttraumatic ligament injury have been investigated by 1.5-Tesla MRI and wrist arthroscopy. Inclusion and exclusion criteria were adopted. Only for SL ligament injury, the arthroscopic findings of complete (stage IV) and partial (stages I–III) SL ligament injury were compared with MRI findings. Statistical analysis, including sensitivity, specificity, positive and negative predictive values, positive and negative likelihood ratios, and the diagnostic odds ratio, was used to compare MRI with arthroscopic findings. Results A total of 146 patients were accepted in the study. In 68 cases of arthroscopic SL ligament lesion, MRI confirmed the diagnosis only in 50% of the cases. In partial SL lesions, MRI was positive in 24.3% and in complete SL lesions, MRI was positive in 80.6% of the cases. In 10 cases of arthroscopic LT ligament lesion, MRI was positive in 30.0% of the cases. In 33 patients with arthroscopic TFCC lesion, MRI was positive in 66.7% of the cases. Conclusion 1.5-T MRI demonstrated to fail in confirming the lesion of SL, LP, and TFCC ligaments respectively in 50, 70, and 33.3% of the cases positive at arthroscopy. In complete SL ligament lesion, MRI reaches a higher sensitivity than in partial lesion. Arthroscopy remains the best method to demonstrate the ligament lesion and obtain more information regarding the extent and quality of the ligament damage. Level of Evidence This is a Level II, retrospective comparative study.

Category: Ankle, Arthroscopy Introduction/Purpose: MRI is the preferred modality for the diagnosis of ankle joint pathology. Musculoskeletal radiologists aim to determine and report both chondral and/or osseous stability/instability of each lesion. The aim of this study was to specifically analyse the reliability of MRI reported findings in predicting the stability of OCL’s in symptomatic patients. Methods: A single centre, single surgeon consecutive series of patients who had undergone an ankle arthroscopy procedure preceded by an MRI scan for symptomatic ankle pathology were included in this retrospective clinical study. All MRI scans were reported by a musculoskeletal radiologist. MRI reports and arthroscopic findings were extracted and analysed. Arthroscopy findings were taken as the gold standard. Results: Between April 2012 and July 2016, 48 patients who fulfilled the criteria were included. There were 27 male and 21 female patients, the average age was 43.4. Average time interval between MRI and arthroscopy was 9 months. There was a significant negative relationship between OCL’s reported as stable on MRI to arthroscopic findings, r=-.31, p=0.03. Of the 21 patients who had OCL’s reported as stable on the MRI, all had unstable lesions on arthroscopic evaluation (100%). One patient had an unstable OCL reported on the MRI and it was also unstable arthroscopically. In 27 patients, there was no mention of the stability of the reported OCL on the MRI, 22 patients (81.5%) had unstable lesions and 5 patients (18.5%) had stable lesions on arthroscopic findings. Conclusion: This study demonstrates that MRI has a poor predictive value for the stability of OCL’s of the ankle. Therefore we recommend that in the symptomatic patient an arthroscopy is indicated irrespective of MRI findings.
