Right knee right pain. Evaluate right knee for medial meniscus tear versus DJD. MENISCI: There is a small inner margin tear of the posterior horn of the medial meniscus. The lateral meniscus is intact. ARTICULAR CARTILAGE AND BONE: There is full thickness loss of cartilage of the weight-bearing portion of the medial femoral condyle. Additionally, there is full thickness loss of articular cartilage of the posterior medial tibial plateau with an underlying high T2 focus within the bone compatible with a subchondral cyst. There is thinning of the articular cartilage of the anterior lateral femoral condyle.There is denuding of the articular cartilage of the lateral 75% of the medial patellar facet along with a small portion of the medial patellar ridge. There is denuding of at least 50% of the articular cartilage of the medial femoral trochlea along the inner margin.LIGAMENTS: The collateral and cruciate ligaments are intact. EXTENSOR MECHANISM: No significant abnormality noted.ADDITIONAL
1. Small inner margin tear of the posterior horn of the medial meniscus. 2. Cartilage loss in the medial and extensor compartments with subchondral cyst formation in the posterior medial tibial plateau.
