Abstract

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 MRIfindings as normal (Group 1), suspicious tear (Group 2), definilte tear (Group 3) based on the morphologic appearance of intrameniscal signal and its relationship to the articular surface. In group 1, thiry eight of 41menisci were found at arthroscopy to be normal. Five of 7 menisci in group 2 and all menisci of group 3 were foundat arthroscopy to be torn. If group 2 and 3 are considered consistent with meniscal tears, sensitivity, specificity and accuracy of MRI ar 91.3%, 92.5% and 92.2% respectively. This results indicate that MRI is capableof demonstrating meniscal tears. with high degree of accuracy. We believe MRI is the imaging technique of choicein evaluating meniscal injuries.
