19-year-old female with left knee pain and instability, assess medial patellofemoral ligament, tibial tuberosity to trochlear groove distance, trochlear dysplasia, cartilage, loose bodies MENISCI: Lateral and medial menisci are intact.ARTICULAR CARTILAGE AND BONE: There is edema type signal within the medial aspect of the patella and associated lateral aspect of the lateral femoral condyle. Near fluid signal intensity within the medial patellofemoral ligament is suggestive of at least a partial tear. Patella alta is noted. The femoral trochlea appears shallow. Small ossicles measuring up to 5 mm are seen medial to the patella correlates with those seen on prior radiographs. Mild soft tissue swelling along the anterior soft tissues over the patella. The TT-TG distance measures approximately 8 mm. LIGAMENTS: The cruciate and collateral ligaments are intact. EXTENSOR MECHANISM: The patellar tendon is intact. The quadriceps tendon is intact.ADDITIONAL
1.At least partial tearing of the medial patellofemoral ligament with edema type signal along the medial aspect of the patella and lateral aspect of the femoral condyle consistent with a recent lateral dislocation and reduction. 2.Patella alta and findings suggestive of trochlear dysplasia. Findings are associated with predisposition to patellar instability.3.Small joint effusion.
