52-year-old male with lateral joint line pain, rule out lateral meniscal tear MENISCI: There is a radial tear of the lateral meniscal body. The lateral meniscal body is mildly extruded laterally. The medial meniscus is intactARTICULAR CARTILAGE AND BONE: There is a 1.6 cm of full-thickness cartilage loss along the lateral tibial plateau with underlying edema in the subchondral bone. Additional edema is present within the lateral tibial plateau more anteriorly with a small subchondral cyst at the ACL insertion. There are areas of partial-thickness cartilage loss along the lateral femoral condyle. Articular cartilage of the medial compartment is intact. There is near full-thickness cartilage loss along the lateral patellar facet with underlying increased T2 signal within the patella, likely reactive. Mild thinning is seen along the medial patellar facet. The trochlear cartilage is intact. Small tricompartmental osteophytes are present. There is an ossicle at the patellar tendon insertion which may be related to old trauma. There is edema along the anterior aspect of the lateral femoral condyle which is likely reactive.LIGAMENTS: The medial and lateral collateral ligament complexes are intact. The ACL and PCL are intact.EXTENSOR MECHANISM: The extensor mechanism is intact.ADDITIONAL
1.Radial tear of the lateral meniscus with associated osteoarthritic changes in the lateral compartment including areas of full-thickness cartilage loss.2.Osteoarthritic changes in the patellofemoral compartment with near full-thickness articular cartilage loss along the lateral facet.
