Background: The aim of this study was to determine the diagnostic value of magnetic resonance imaging (MRI) in the diagnosis of knee injuries. Materials and Methods: Ninety?eight consecutive patients were enrolled in the study. In all patients, MRI and arthroscopy were performed and the results were compared. Results: MRI was most sensitive in the detection of medial meniscus injuries,and the highest specificity and negative predictive value (NPV) were found in the detection of posterior cruciate ligament injuries.Conclusion: MRI is a valuable tool, and according to its high NPV, normal MRI can prevent unnecessary arthroscopic interventions.

Key words: Cruciate ligaments, diagnostic value, knee injury, magnetic resonance imaging
