Abstract

Introduction The knee is one of the most frequently injured joints. Clinical tests in the diagnosis of meniscus and ligament injuries have limitations and it may not be possible to elicit objective signs repeatedly. MRI, has been shown to improve diagnostic accuracy in many knee disorders. Its principal attractiveness over arthroscopy is that it is noninvasive. To determine the effectiveness of magnetic resonance imaging in the appropriate identification of traumatic intra articular knee lesions, we compared its findings with clinical examination and arthroscopy as a gold standard technique in a descriptive cross sectional study. Materials and Methods Overall 100 patients with knee trauma were entered and completed the study. All patients had thorough clinical examination By experienced physicians. An MRI of the affected knee was requested in all patients. Arthroscopies were performed for all of them. Results Overall 55 knees were reported to have ACL tear arthroscopically, Meniscal injuries were found in 75 cases. We found correlation between posterior drawer test, MRI report of PCL tear and arthroscopic PCL tear. The sensitivity of MRI for detecting Meniscal tear: represented high, for bucket handle tear of medial meniscus, and high specificity for Lateral meniscal tear. Conclusion It is concluded that arthroscopy still remains the gold standard technique. More powerful MRI scan equipments with better soft wares will be needed in order to have much better diagnosis.
