30-year-old male with knee pain and mechanical symptoms. Evaluate for medial meniscus tear. MENISCI: There is blunting and deformity of the posterior horn of the lateral meniscus consistent with complex tearing which extends to involve the body of the meniscus. The anterior horn appears intact. There is blunting of the posterior horn of the medial meniscus which presumably represents postsurgical changes from prior partial meniscectomy. No fluid-filled defect is identified to suggest a re-tear.ARTICULAR CARTILAGE AND BONE: There is a near full-thickness articular cartilage cleft along the lateral facet of the patella. There are near full-thickness to full-thickness articular cartilage class along the lateral facet of the femoral trochlea, central femoral trochlea and medial facet of the femoral trochlea. There is a full-thickness articular cartilage cleft along the medial facet of the patella.There is full-thickness articular cartilage degeneration along the weightbearing surface of the lateral femoral condyle above the posterior horn of the meniscus and the lateral aspect of the lateral tibial plateau with underlying degenerative subchondral signal abnormality. The articular cartilage of the medial compartment appears relatively spared. There are tricompartmental osteophytes.LIGAMENTS: The cruciate and collateral ligaments appear intact. EXTENSOR MECHANISM: There is slight thickening of the proximal patellar tendon which may reflect mild tendinosis. The extensor mechanism appears intact.ADDITIONAL
1. Tearing of the lateral meniscus as described above. Postsurgical changes of the medial meniscus as described above.2. Moderate size joint effusion with findings suggestive of a synovitis. 3. Full-thickness articular cartilage degeneration as described above. Mild osteoarthritic changes of the knee as described above.4. Mild patellar tendinosis.
