58-year-old female with medial right knee pain. MENISCI: There is increased signal abnormality within the posterior horn of the medial meniscus consistent with intrasubstance degeneration. There is blunting and increased signal abnormality which extends to the femoral and tibial articular surfaces consistent with complex tearing of the posterior horn of the medial meniscus with a radial component. The anterior horn appears intact. The lateral meniscus appears intact.ARTICULAR CARTILAGE AND BONE: There is full-thickness articular cartilage degeneration along the weightbearing surface of the medial femoral condyle and medial tibial plateau with underlying degenerative subchondral signal abnormality. There is subjective thickening of the articular cartilage of the lateral tibiofemoral compartment. There is thinning of the articular cartilage along the medial facet of the patella. There is tricompartmental osteophyte formation.LIGAMENTS: The ACL and PCL appear intact. The LCL appears intact. There is thickening of the proximal fibers of the superficial band of the MCL which may represent prior injury/sprain. EXTENSOR MECHANISM: The extensor mechanism appears intact.ADDITIONAL
1. Severe degenerative osteoarthritic changes of the knee, most pronounced along the medial tibiofemoral compartment with associated full-thickness articular cartilage degeneration.2. Complex tearing of the medial meniscus with a radial component as described above.
