Magnetic Resonance Imaging(MRI) and arthroscopic findings of thirty two patients with clinically suspected meniscal tears were correlated to evaluate the diagnostic accuracy of MRI in meniscal injury. We grouped MRI findings as normal (Group 1) suspicious tear (Group 2) definite tear (Group 3) based on the morphologic appearance of intrameniscal signal and its relationship to the articular surface. In group 1 thirty eight of 41 menisci were found at arthroscopy to be normal. Five of 7 menisci in group 2 and all menisci of group 3 were found at arthroscopy to be torn. If group 2 and 3 are considered consistent with meniscal tears sensitivity specificity and accuracy of MRI are 91.3% 92.5% and 92.2% respectively. This results indicate that MRI is capable of demonstrating meniscal tears with high degree of accuracy. We believe MRI is the imaging technique of choice in evaluating meniscal injuries.
