Left knee pain MENISCI: There is globular increased signal of the medial meniscus, particularly the posterior horn and body, representing intrasubstance degeneration. Additionally, there is a small focus of linear increased signal at the junction of the posterior horn and body extending to the free edge which is thought to represent a new horizontal tear. The lateral meniscus is unremarkable. ARTICULAR CARTILAGE AND BONE: There has been progression of cartilage loss of the weightbearing portion of the medial femoral condyle with areas of new full-thickness loss. A small focus of near full-thickness loss of cartilage along the tibial plateau is also noted at the level of the posterior horn. There is focal partial-thickness cartilage degeneration of the weightbearing portion of both the lateral femoral condyle and tibial plateau. This has progressed from the prior exam. Additionally, there is progression of articular cartilage loss of the medial patellar facet with worsening cartilage loss of the medial femoral trochlea as well. LIGAMENTS: The cruciate and collateral ligaments are within normal limits. EXTENSOR MECHANISM: The extensor mechanism is within normal limits.ADDITIONAL
