Status post right knee arthroscopy microfracture of the medial compartment and patellofemoral joint. Evaluate for healing. MENISCI: There is blunting of the body of the medial meniscus likely reflecting post-surgical changes. Within this remnant, there is new horizontal signal abnormality which may represent a superimposed tear. The lateral meniscus is intact. ARTICULAR CARTILAGE AND BONE: There is redemonstration of delamination of the articular cartilage of the weight-bearing portion of the medial femoral condyle. Within this area of delamination, there is a new full thickness cartilage defect measuring approximately 1 cm in the AP dimension. There is chondral softening of lateral femoral condyle articular cartilage without full thickness defect. There is mild focal degeneration of the articular cartilage of the lateral tibial plateau along the lateral aspect of the tibial spine. There is significant thinning of the articular cartilage of the medial patellar facet, as well as focal near full-thickness degeneration of the articular cartilage of the lateral patellar facet. There is also full-thickness degeneration of the articular cartilage of the femoral trochlear centrally, with near full-thickness degeneration along the medial and lateral facets.There is interval decrease in bone marrow edema within the medial femoral condyle. LIGAMENTS: The collateral and cruciate ligaments are intact. EXTENSOR MECHANISM: No significant abnormality noted.ADDITIONAL
1. New full thickness chondral defect within a region of delamination of the medial femoral condyle articular cartilage. 2. New superimposed horizontal tear of the remnant of the body of the medial meniscus.3. Improved medial femoral condyle bone edema.
