Patellar dislocation MENISCI: The medial and lateral menisci are intact.ARTICULAR CARTILAGE AND BONE: The articular cartilage of the lateral, medial, and patellofemoral compartments is intact. There is a minimal amount of nonspecific marrow edema within the lateral femoral condyle posteriorly.LIGAMENTS: The cruciate and collateral ligaments are intact. EXTENSOR MECHANISM: There is patella alta although the patellar tendon is intact. There is lateral translation of the patella with respect to the femoral trochlea although the MPFL appears intact. The TT to TG distance is 1.8 cm and the trochlear depth is 5 mm. There is minimal increased signal superolateral portion of Hoffa's fat pad.ADDITIONAL
1. Lateral translation of the patella with respect to the trochlea although the MPFL, TT to TG distance, and trochlea depth appear normal.2. Small amount of nonspecific marrow edema within the lateral femoral condyle which may relate to remote patellar dislocation. Mild edema within the superolateral portion of Hoffa's fat pad may also indicate a component of patellar impingement.
