[Comparative study on MRI and arthroscopic findings of knee joint].

A retrospective analysis of MRI results of knee joints of 40 patients with routine arthroscopic operation was performed by the authors. The results showed the accuracy rate of MRI for diagnosis of internal and external meniscus injury was 84.25% and 87.5%, and that for anterior and posterior cruciate ligament was 90.25% and 100.00%, respectively. Although MRI possessed good resolving capacity for soft tissue, the authors stress the attention should be paid to clinical data collection.
