Right knee stiffness MENISCI: There is abnormal signal intensity and morphology of the posterior horn of the medial meniscus which extends into the body and is consistent with complex tearing. The lateral meniscus is intact.ARTICULAR CARTILAGE AND BONE: There is full-thickness loss of the articular cartilage of the weightbearing portion of the medial femoral condyle particularly posteriorly with areas of less severe diffuse loss. There is diffuse thinning of the articular cartilage of the lateral femoral condyle but without discrete full-thickness defect. There is severe articular cartilage loss of the patellofemoral compartment with areas of full-thickness loss particularly affecting the medial compartment. Areas of full-thickness degeneration are also evident within the femoral trochlea, particularly laterally. There are small tricompartmental osteophytes and associated degenerative marrow changes within the femoral condyles bilaterally. A 2 cm ovoid focus is identified within the intercondylar notch best seen on series 5 image 18 which may represent a displaced chondral fragment.LIGAMENTS: The cruciate and collateral ligaments are intact. EXTENSOR MECHANISM: No significant abnormality noted.ADDITIONAL
1. Complex tearing of the medial meniscus.2. Tricompartmental osteoarthritis with areas of full-thickness articular cartilage loss affecting the medial and patellofemoral compartments. A 2 cm ovoid focus within the intercondylar notch may represent a displaced chondral fragment.3. Nonaggressive appearing chondroid lesion within the head of the fibula with possible adjacent ganglion cyst at the tibiofibular articulation.
