Reason: right knee pain, evaluate for meniscus tearing History: above MENISCI: There is a full-thickness radial tear of the posterior horn of the lateral meniscus near its root with extension into the body of the meniscus. The posterior root of the lateral meniscus appears thickened which may represent a flipped meniscal fragment (image 17; series 7). There is intrasubstance degeneration of the posterior horn and deformity which may reflect degenerative tearing. There is a horizontal tear of the anterior horn of the lateral meniscus with small parameniscal cyst formation. The medial meniscus appears intact.ARTICULAR CARTILAGE AND BONE: There is full-thickness articular cartilage degeneration along the weightbearing surface of the lateral femoral condyle above the posterior horn of the meniscus with degenerative subchondral signal abnormality. There is full thickness degeneration of the lateral tibial plateau as well with underlying degenerative subchondral signal abnormality. There is subjective thinning of the medial tibiofemoral compartment. There is a full-thickness articular cartilage cleft along the medial facet of the patella with underlying subchondral signal abnormality. There are tricompartmental osteophytes.LIGAMENTS: The cruciate and collateral ligaments appear intact. EXTENSOR MECHANISM: The extensor mechanism appears intact.ADDITIONAL
1. Tearing of the lateral meniscus as described above.2. Osteoarthritis of the right knee including full-thickness articular cartilage degeneration most pronounced along the lateral tibiofemoral compartment as described above.3. Moderate size joint effusion with a lobulated Baker's cyst which may reflect a synovitis.
