Knee pain, history of microfracture surgery MENISCI: There is increased signal within the anterior horn of the lateral meniscus suggesting intrasubstance degeneration although no discrete tear is identified. The medial meniscus is intact.ARTICULAR CARTILAGE AND BONE: There is thinning of the articular cartilage of the medial compartment although no discrete full-thickness defect is identified. Moderate diffuse thinning of the patellar cartilage is noted with areas of partial-thickness defects seen laterally. There is near full-thickness loss of the articular cartilage of the femoral trochlea. A small focus of marrow changes noted within the lateral tibial plateau may relate to the area of prior intervention.LIGAMENTS: The cruciate and collateral ligaments are intact. EXTENSOR MECHANISM: Mildly increased signal is noted within the patellar tendon which may reflect mild tendinosis.ADDITIONAL
Moderate articular cartilage loss of the patellofemoral compartment with milder changes noted in the medial and lateral compartments. Remaining internal structures of the knee are otherwise intact.
