20-year-old female patient with pain, dislocation. Question of patella ligament tear, loose body. MENISCI: The medial and lateral menisci are intact.ARTICULAR CARTILAGE AND BONE: The articular cartilage of all three compartments is intact. Bone marrow signal is within normal limits.LIGAMENTS: The collateral and cruciate ligaments are intact. EXTENSOR MECHANISM: The patellar and quadriceps tendons are intact. There is subtle edema in the superolateral aspect of Hoffa's fat pad which may suggest patellofemoral instability, similar to the prior study. ADDITIONAL
