Background: Knee is one of the largest and most complex joints in the body. Disease processes and injuries that disrupt ligaments, menisci, articular cartilage and other structures of the knee cause painful knee resulting in significant morbidity and disability. The present study was conducted to assess role of MRI in assessment of knee injuries. Materials & Methods: 84 patients with knee injury of both genders were enrolled. X-ray knee joint (AP and lateral view) and the MRI was done. Arthroscopy was done in all patients. MR scans were carried out on 1.5 tesla MR machine (Siemens) with sense extremity coil. Findings of arthroscopy were correlated with MRI findings. Results: Out of 84 patients, males were 54 and females were 30. On MRI, ACL, PCL, LM and MM was tear in 64, 12, 12 and 60 and normal in 20, 72, 72 and 24 respectively. The difference was significant (P< 0.05). MRI showed sensitivity of 94%, specificity of 78%, PPV of 95% and NPV of 50%in detection of Knee injuries. Conclusion: MRI is a useful non-invasive imaging aid having high diagnostic accuracyfor diagnosis of knee joint injuries.
