MRI EVALUATION OF MENISCAL AND LIGAMENTOUS INJURIES OF KNEE IN CORRELATION WITH ARTHROSCOPY

Background - In knee joint injuries, clinical examination, radiographs and CT scan is not enough to diagnose many internal derangements of this joint. MR studies are required to assess the injuries of the menisci, cartilage ligaments or bone. A cross-sectional, Materials and methodsanalytical–observational study was conducted at the Department of Radiodiagnosis. A total of 65 patients with clinical suspicion of knee ligament injury and were referred for MRI were examined, 41 patients were males and 24 were females, their ages ranging from18 to 60 yrs. ACL Resultstear was the most common lesion, presented in 53.84 % cases out of which 29.32% cases were partial tear and 24.62% cases were complete tear. Medial Meniscus tear was the second most common lesion. 25% cases presented with combined injuries and 75% cases presented with isolated injuries. The predominant pattern was ACL and MM tears, followed by ACL tear and LM tears. Correlation between MRI and arthroscopic ndings are statistically signicant with (88%) of the cases showed good correlation between MRI and arthroscopic ndings. The study Conclusionsrevealed the ability of MRI in evaluation of the various internal derangements, including their detection, types (partial/complete tear) localization, characterization and assessment of extent of damage and the strength of correlation between MRI and arthroscopic helped the orthopaedic surgeons as a conservative approach was indicated in partial tears while a repair/reconstruction was indicated in a complete tear.
