Pain, clicking in left knee. Evaluate for meniscal tear. MENISCI: The menisci appear normal. I see no tear.ARTICULAR CARTILAGE AND BONE: There is full-thickness degeneration of the articular cartilage of the femoral trochlea centrally and inferiorly extending along the anterior margin of the medial femoral condyle, with cyst formation and edema-type signal in the underlying subchondral marrow. The articular cartilage of the patella appears intact. The articular cartilage of the tibiofemoral compartments likewise appears intact. There is mild edema-type signal within the medial femoral condyle posteriorly at the level of the physeal scar, perhaps simply representing mild enthesopathic changes near the origin of the medial head of the gastrocnemius.LIGAMENTS: Cruciate and collateral ligaments are intact. EXTENSOR MECHANISM: The extensor mechanism is intact. Mild enthesopathic changes are noted at the insertion of the distal quadriceps tendon on the patella, not necessarily of any clinical significance.ADDITIONAL
Full-thickness cartilage degeneration involving the femoral trochlea and anterior margin of the medial femoral condyle. I see no meniscal tear. Other findings as above.
