23-year-old female with recent injury/fall. Assess for ACL tear. MENISCI: The medial and lateral menisci appear intact.ARTICULAR CARTILAGE AND BONE: Numerous intramedullary cortically-based lesions are noted, as seen on prior imaging studies, previously described as nonossifying fibromas. There has been interval decrease in fluid signal intensity and increase in fat signal intensity suggesting some interval healing of these lesions. There are bone contusions identified along the posterior aspect of the lateral tibial plateau and lateral femoral condyle above the anterior horn of the lateral meniscus. An additional contusion is identified along the posterior aspect of the medial tibial plateau. We see no fluid-filled articular cartilage defects.LIGAMENTS: The is a complete rupture of the ACL through its mid to proximal fibers. The PCL appears intact. The lateral collateral ligament and medial collateral ligament appear intact.EXTENSOR MECHANISM: The extensor mechanism appears intact.ADDITIONAL
ACL tear and other findings as described above.
