Moragas Manouver Correlation Clinically Arthroscopy, in the Diagnosis of Lateral Meniscal Injury

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.
