Reason: evaluate for loose bodies History: lateral joint line pain MENISCI: There are postsurgical changes of lateral partial meniscectomy with absence of the lateral meniscal body and degeneration / tearing of the posterior horn. There is increased signal within the medial meniscus which may reflect mucoid degeneration, however no discrete tear is identified.ARTICULAR CARTILAGE AND BONE: A small amount of increased marrow signal along the lateral femoral condyle is likely reactive. There are findings of prior chondroplasty along the lateral femoral condyle. There is a large area of full-thickness cartilage loss along the lateral femoral condyle measuring up to 2.4 cm and along the lateral tibial plateau measuring 2.1 cm. The cartilage of the medial compartment is diffusely thinned without a fluid-filled defect present. The patellar and trochlear cartilage is intact. Small tricompartmental osteophytes are present.LIGAMENTS: The medial and lateral collateral ligament complexes are intact. The ACL is thin but intact. The PCL is intact. EXTENSOR MECHANISM: Extensor mechanism is intact.ADDITIONAL
1.Postsurgical changes of lateral partial meniscectomy with absence of the lateral meniscal body. Degeneration and tearing of the posterior horn.2.Moderate to severe osteoarthritis with large areas of full-thickness cartilage loss in the lateral compartment.
