Right knee pain. History of Fulkerson procedure. Evaluate for chondromalacia of the patella, pes bursitis, medial meniscal tear. MENISCI: The menisci demonstrate normal signal characteristics and morphology without evidence of discrete tear.ARTICULAR CARTILAGE AND BONE: There is thinning of the articular cartilage of the medial facet of the patella, with poorly defined increased signal intensity extending from the surface to the bone, indicating full thickness degeneration. There is degenerative edema-signal type abnormality in the subchondral bone at the median eminence of the patella. The articular cartilage of the lateral facet, trochlea, and medial and lateral femoral condyles is unremarkable. There are post operative changes compatible with stated history of Fulkerson procedure, with prominence of the anterior tibial tuberosity.LIGAMENTS: The anterior cruciate, posterior cruciate, medial collateral, lateral collateral, and popliteal ligaments are intact.EXTENSOR MECHANISM: The extensor mechanism is intact.ADDITIONAL
1.Postoperative changes as described above.2.Full-thickness degeneration of the articular cartilage of the medial patellar facet.3.No evidence of meniscal tear or pes anserine bursitis.
