Reason: pain in the left knee, concern for ACL injury MENISCI: There is truncation of the posterior horn of the lateral meniscus with abnormal linear intermediate signal intensity, consistent with a predominantly radial tear. The medial meniscus appears intact.ARTICULAR CARTILAGE AND BONE: There are no focal defects in the articular cartilage. There is extensive T2 hyperintense signal within the posterolateral and posteromedial tibial plateau and lateral femoral condyle, consistent with bone marrow edema/contusion. There is slight depression of the lateral femoral condyle with associated bone marrow edema.LIGAMENTS: There is complete disruption of the fibers of the anterior cruciate ligament with abnormal globular intermediate signal, consistent with complete tear. The PCL, MCL, and LCL are intact. EXTENSOR MECHANISM: The quadriceps and patellar tendons are intact.ADDITIONAL
1. Complete ACL tear.2. Radial tear through the posterior horn of the lateral meniscus.
