Reason: meniscus tear History: pain and catching. MENISCI: The medial and lateral menisci are intact.ARTICULAR CARTILAGE AND BONE: Diffuse thinning of the medial compartment articular cartilage. Diffuse thinning of the lateral compartment articular cartilage with at least near full-thickness defect involving the weightbearing portion of the lateral tibial plateau measuring approximately 8 mm in AP dimension with associated underlying subchondral bone marrow edema. Diffuse thinning of the patellofemoral compartment without discrete defect.LIGAMENTS: The cruciate and collateral ligaments are intact. EXTENSOR MECHANISM: The extensor mechanism is intact.ADDITIONAL
Osteoarthritis, greatest in the lateral compartment, where there is a near full-thickness defect involving the weightbearing portion of the lateral tibial plateau.
