14-year-old male with left knee pain. Assess left knee MPFL, trochlear dysplasia, loose bodies, and measure TT-TG. Per the technologist notes, the patient had left knee surgery in 2014 for anchoring the patella. MENISCI: The medial and lateral menisci are intact.ARTICULAR CARTILAGE AND BONE: There is bone marrow edema within the anterolateral aspect of the medial femoral condyle which appears slightly progressed since prior study. This is nonspecific and may represent a contusion. The previously seen edema within the lateral femoral condyle appears resolved. The articular cartilage of the patella appears intact. The articular cartilage of the trochlea appears intact. There appears to be a moderately deep focal defect within the lateral femoral condyle measuring up to 1.5 cm in AP dimension. This appears more prominent on prior study. The articular cartilage of the medial compartment appears intact.LIGAMENTS: The cruciate and collateral ligaments are intact.EXTENSOR MECHANISM: The extensor mechanism is intact.ADDITIONAL
1. No displacement of the patella with respect to the femoral trochlea with measurements as above. 2. No evidence of ligamentous or meniscal injury.3. Small joint effusion with moderately deep focal defect within the lateral femoral condyle.
