The lateral meniscus appears intact.ARTICULAR CARTILAGE AND BONE: There is a focus of intermediate to high signal intensity within the articular cartilage of the patella, centrally, indicating focal degeneration, measuring approximately 8 mm in diameter. There is a small focus of signal abnormality, with a depth of approximately 2 to 3 mm, within the underlying subchondral bone with adjacent bone marrow edema. These findings are compatible with the stated history of an osteochondral defect. There is relative sparing of the articular cartilage of the medial and lateral compartments.LIGAMENTS: The cruciate and collateral ligaments appear intact.
