Male 19 years old Reason: Patella dislocation. Evaluate MPFL and for loose body History: Recurrent dislocations MENISCI: Medial and lateral menisci are intact. ARTICULAR CARTILAGE AND BONE: There is T2 hyperintense bone marrow edema signal in the lateral femoral condyle and the lateral tibial plateau. Lateral trochlear inclination measuring 4 degrees consistent with trochlear dysplasia.LIGAMENTS: Increased signal and attenuation of the medial patellofemoral ligament consistent with history of patellar dislocation. Cruciate and collateral ligaments are intact. EXTENSOR MECHANISM: Extensor mechanism is intact.ADDITIONAL
1.Sequelae of patellar dislocation including injury of the medial patellofemoral ligament, and lateral femoral condyle bone contusion. 2.Large joint effusion. 3.Findings consistent with trochlear dysplasia.
