Reason: R LCL and ACL rupture, lateral meniscus tear History: R knee pain/instability MENISCI: The posterior horn of the medial meniscus appears markedly small and truncated. While the etiology is unclear and this may be related to surgery it is more likely secondary to tearing. The lateral meniscus appears grossly intact.ARTICULAR CARTILAGE AND BONE: No significant abnormality noted.LIGAMENTS: Postsurgical changes following ACL graft reconstruction are noted. The graft fibers appear indistinct, consistent with tearing. There is impingement of the remnant fibers of the ACL graft in the intercondylar notch. There is buckling of the PCL, however it appears grossly intact. The MCL and LCL are intact.EXTENSOR MECHANISM: The patellar and quadriceps tendons appear grossly intact.ADDITIONAL
1. Truncation of the posterior horn of the medial meniscus, most likely secondary to tearing.2. Tearing of the ACL graft with impingement in the intercondylar notch of the remnant fibers.
