Abstract

Purpose: The purpose of this study was to compare the preoperative magnetic resonance image (MRI) findings with postoperative arthroscopic findings on meniscus injury with anterior cruciate ligament (ACL) rupture. Materials and Methods: We reviewed MRI images and arthroscopic findings of 225 patients treated by ACL reconstruction due to rupture, from February 2001 to November 2010. There were 154 cases of meniscus tear in arthroscopic findings. We examined the sensitivity for detecting meniscal tears varied with the presence of a rupture of the ACL, with the location of the tear within the meniscus, and among configurations of meniscal tears. Results: In the presence of a rupture of the ACL, the sensitivity of MRI was 0.88 for medial meniscal tears and 0.69 for lateral meniscal tears. And sensitivity of MRI was lowest in posterior horn and peripheral portion tears in lateral meniscus injury accompanying ACL rupture, sensitivity was low in anterior horn and flap shape tears in medial meniscus injury accompanying ACL rupture. Conclusion: In Meniscus injury with ACL rupture, a special attention shoulder given to the posterior horn and peripheral portion injury in lateral meniscus during arthroscopic surgery due to difficulty in detecting on MRI.
