Background:One of the biggest and most intricate joints in the body is the knee. Injuries and disease processes that damage the knee's ligaments, menisci, articular cartilage, and other components can cause painful knees that lead to serious morbidity and disability. The present study was conducted to assess the efficacy of MRI in evaluation of knee joint pathologies.Materials & Methods:80 patients with painful knee joint scheduled for MRI of both genders were selected. Using MRI scans conducted using a Siemens 1.5 Tesla High gradient MRI scanner, the knee joint was assessed, and different knee joint pathologies were noted. T1 and T2 weighted sequences in sagittal planes, PD weighted sequences in axial, coronal, and sagittal planes, and fat suppressed T2 or STIR sequences where specified were all part of the MRI protocol.Results: Age group 10-30 years had 32, 30-50 years had 30 and 50-70 31-40 years had 18 patients. The difference was non- significant (P> 0.05). Common knee pathologies were medial collateral ligament tears in 10, lateral collateral ligament tears in 18, chondromalacia patellae in 9, osteochondritisdissecans in 6, rheumatoid arthritis in 4, infection in 2, anterior cruciate ligament tear in 10, posterior cruciate ligament tear in 7, medial meniscal tears in 8, and lateral meniscal tears in 6 patients. The difference was significant (P< 0.05).Conclusion:An accurate, non-invasive, and reasonably priced way to assess a sore knee is with magnetic resonance imaging (MRI).
