Reason: Meniscus Tear vs Chondromalacia History: Medial Pain MENISCI: Note is made of a focus of intermediate signal intensity within the posterior horn of the medial meniscus, just medial to its root, extending to the tibial articular surface, suggesting a small undersurface tear that appears more prominent than on the prior study. There is a small cyst within the underlying subchondral bone. There is intrasubstance degeneration within the posterior horn and body of the medial meniscus. The lateral meniscus appears intact.ARTICULAR CARTILAGE AND BONE: The articular cartilage is normal for age with no fluid-filled defects.LIGAMENTS: The cruciate and collateral ligaments appear intact. EXTENSOR MECHANISM: The extensor mechanism appears intact.ADDITIONAL
Small focal undersurface tear of the posterior horn of the medial meniscus, near its root, with subchondral cyst formation in the underlying tibial plateau. The knee otherwise appears normal.
