49-year-old female with history of right knee medial joint line pain. MENISCI: There is increased signal within the posterior horn of a truncated medial meniscus (from prior partial meniscectomy) appearing similar to the prior exam and likely representing degeneration. There is no evidence of new tearing. The anterior horn of the medial meniscus is unremarkable.The lateral meniscus is intact.ARTICULAR CARTILAGE AND BONE: There is progressive articular cartilage loss about the medial femoral condyle and medial tibial plateau with near bone on bone apposition. There is increased bone marrow edema within the underlying bone. There is marked articular cartilage loss about the medial patellar facet as well as thinning of the cartilage along the medial femoral trochlea. There are tricompartmental osteophytes.LIGAMENTS: The ACL, PCL, MCL, and LCL are intact. EXTENSOR MECHANISM: The extensor mechanism is unremarkable.ADDITIONAL
1.Increased signal about the remaining posterior horn of the medial meniscus compatible with continued degeneration, but we see no discrete new tear.2.Progressive articular cartilage loss especially at the medial tibiofemoral compartment with near bone-on-bone apposition and adjacent bone marrow edema.3.Small joint effusion.
