Right knee pain MENISCI: The medial meniscus is intact. There is abnormal signal and morphology of the body and anterior horn of the lateral meniscus likely reflecting combination of postsurgical change and tearing. This appears similar to the exam dated 8/16/2012.ARTICULAR CARTILAGE AND BONE: There are new full-thickness cartilage defects within the medial compartment affecting both the femoral condyle and tibial plateau. The largest extent measures approximately 2.3 cm in the greatest AP dimension within the mid to posterior femoral condyle. There is associated underlying reactive marrow change which is also new from the prior exam. There is mild thinning of the articular cartilage of the lateral and patellofemoral compartments without discrete full-thickness defects.LIGAMENTS: The cruciate and collateral ligaments are intact. EXTENSOR MECHANISM: The quadriceps and patellar tendons are intact.ADDITIONAL

New large full-thickness defects of the articular cartilage of the medial compartment affecting both the femoral condyle and tibial plateau. The articular cartilage of the lateral patellofemoral compartments is thinned at otherwise intact.
