Right knee pain and stiffness Examination is limited by motion artifact and by the patient's body habitus precluding the use of a dedicated knee coil.MENISCI: There is maceration of the posterior horn of the medial meniscus with absence of much of the body reflecting extensive tearing. The anterior horn appears relatively intact. The lateral meniscus appears preserved.ARTICULAR CARTILAGE AND BONE: There is extensive articular cartilage loss of the medial compartment and both the tibial and femoral components. There is diffuse thinning of the articular cartilage of the lateral compartment but within the limits of the exam, we see no discrete full-thickness defect. There is diffuse thinning of the articular cartilage of the patellofemoral compartment with scattered areas of partial-thickness degeneration. There are large tricompartmental osteophytes. There is diffuse marrow edema throughout the medial compartment which is likely degenerative in nature.LIGAMENTS: There is poor visualization of the ACL although there are some fibers seen traversing the intercondylar notch and this is likely the result of extensive mucoid degeneration. The PCL is intact. The collateral ligaments are intact. EXTENSOR MECHANISM: The quadriceps and patellar tendons are relatively intact.ADDITIONAL
