63-year-old male with knee giving way and knee pain. Evaluate for loose body/meniscus tear. MENISCI: There is increased signal abnormality within the posterior horn and body of the medial meniscus indicating intrasubstance degeneration, but we see no discrete tear. The lateral meniscus appears intact.ARTICULAR CARTILAGE AND BONE: Moderate osteoarthritis affects the patellofemoral joint with articular cartilage thinning and subchondral cysts. There are focal areas of full-thickness cartilage loss and subchondral cysts. There are small tricompartmental osteophytes. There are multiple loose bodies within the suprapatellar pouch, most of which are under 5 mm, although one within the anteromedial aspect of the joint measures just over 1 cm in its greatest dimension.LIGAMENTS: The cruciate and collateral ligaments appear intact. EXTENSOR MECHANISM: The extensor mechanism appears intact.ADDITIONAL
