Pain after fall Note that the examination is limited by the patient's body habitus preventing the use of routine knee coil.MENISCI: The lateral meniscus is intact. There is abnormal morphology and signal intensity of the posterior horn of the medial meniscus reflecting horizontally oriented tearing.ARTICULAR CARTILAGE AND BONE: There is severe, essentially full-thickness loss of the articular cartilage of the medial compartment both along the femoral condyle and tibial plateau. There is moderate diffuse thinning of the articular cartilage of the lateral compartment with areas of full-thickness loss anteriorly. There is severe articular cartilage loss of the patellofemoral compartment as well with full-thickness loss along the lateral patellar facet. Large tricompartmental osteophytes are noted.LIGAMENTS: There is increased intrasubstance signal of the ACL although the ACL itself appears intact. The posterior cruciate ligament and collateral ligaments are intact. EXTENSOR MECHANISM: No significant abnormality noted.ADDITIONAL
1. Tear of the posterior horn of the medial meniscus.2. Severe tricompartmental articular cartilage loss/osteoarthritis most notably within the medial compartment.3. Myxomatous degeneration of the ACL which is otherwise intact.4. Moderate joint effusion with probable mild synovitis.
