23-year-old male with pain and giving way. Presents with meniscus injury. MENISCI: There is a bucket-handle tear or inner margin tear of the medial meniscus with an apparent meniscal fragment displaced posteriorly, near the medial femoral condyle. There is linear increased signal abnormality within the body of the lateral meniscus which extends to the tibial and femoral articular surface consistent with a complex tear. The anterior and posterior horn appear intact.ARTICULAR CARTILAGE AND BONE: There is focal full-thickness articular cartilage degeneration along the weightbearing surface of the lateral femoral condyle with underlying subchondral signal abnormality. There is also focal full-thickness articular cartilage degeneration along the posterior aspect of the lateral tibial plateau and medial tibial plateau with underlying subchondral signal abnormality. LIGAMENTS: There is complete disruption of the ACL. There is no increased signal abnormality on fluid sensitive sequences suggesting that this may be chronic in etiology. The PCL appears intact. The MCL and LCL appear intact.EXTENSOR MECHANISM: The extensor mechanism appears intact.ADDITIONAL
1. Chronic appearing disruption of the ACL. 2. Complex tear of the lateral meniscus and bucket handle tear of the medial meniscus as described above.3. Full thickness articular cartilage degeneration as described above.
