Reason: Right knee lateral meniscus tear History: Right knee pain MENISCI: There is undersurface fraying/degenerative tearing of the posterior horn lateral meniscus. There is also fraying/degenerative tearing of the free edge of the body of the lateral meniscus. The anterior horn appears intact. The medial meniscus appears intact.ARTICULAR CARTILAGE AND BONE: There is focal near full-thickness to full-thickness articular cartilage degeneration along the lateral femoral condyle, posteriorly (image 9; series 9). There is also focal near full-thickness articular cartilage degeneration along the weightbearing portion of the lateral femoral condyle, above the posterior horn of the meniscus (image 10; series 9). There is subjective thinning of the medial tibiofemoral and patellofemoral articular cartilage. There are small tricompartmental osteophytes.LIGAMENTS: There are lobulated foci of fluid signal intensity along the posterior aspect of the distal fibers of the PCL as well as within the posterior aspect of the tibial plateau at the level of the insertion of the PCL likely representing mucoid degeneration. The ACL appears intact. The LCL and MCL appear intact. EXTENSOR MECHANISM: The extensor mechanism appears intact.ADDITIONAL
1. Degeneration/tearing of the lateral meniscus as described above. The medial meniscus appears intact. 2. Osteoarthritis of the right knee with focal full-thickness articular cartilage degeneration as described above.
