51-year-old male with pain. Evaluate lateral meniscus MENISCI: There is deformity and increased signal abnormality within the posterior horn of the medial meniscus which extends to the femoral articular surface consistent with degenerative tearing that extends to the body of the meniscus. The anterior horn appears intact. There is blunting of the free edge of the posterior horn of the lateral meniscus consistent with degeneration/tearing. No fluid-filled tear is evident. The anterior horn appears intact.ARTICULAR CARTILAGE AND BONE: There are tricompartmental osteophytes. There is a full-thickness articular cartilage cleft along the medial facet of the patella. There is articular cartilage degeneration along the medial facet of the femoral trochlea. There is full-thickness articular cartilage cleft along the lateral facet of the femoral trochlea, centrally. There is full-thickness articular cartilage degeneration along the weightbearing surface of the medial femoral condyle. There is also full-thickness articular cartilage degeneration along the medial aspect of the medial tibial plateau with underlying subchondral cyst formation. There is focal full-thickness articular cartilage degeneration along the weightbearing surface of the lateral tibial plateau with underlying subchondral cyst formation. There is full-thickness articular cartilage degeneration along the lateral femoral condyle with underlying degenerative subchondral signal abnormality.LIGAMENTS: There is thickening of the proximal and mid substance fibers of the ACL indicating prior injury or sprain. The ACL appears intact. The PCL appears intact. The MCL and LCL appear intact.EXTENSOR MECHANISM: The extensor mechanism appears intact.ADDITIONAL
1. Osteoarthritis of the left knee with full-thickness articular cartilage degeneration as described above.2. Degeneration/degenerative tearing of the medial and lateral meniscus as described above.3. Other findings as described above.
