History of meniscal repair in 2001 with subsequent injury in 2009. Now complains of right knee pain. Due to the patient's body habitus, the high resolution coil could not be used. An alternative coil was used which results in slightly suboptimal image quality.MENISCI: There is marked deformity of the posterior horn of the lateral meniscus with fluid signal intensity in its substance indicating extensive complex tearing. This tearing extends into the body of the lateral meniscus and there is anterior extrusion of the anterior horn. We see no discrete tearing of the medial meniscus.ARTICULAR CARTILAGE AND BONE: There is full-thickness degeneration of the articular cartilage of the lateral femoral condyle and lateral tibial plateau posteriorly with underlying subchondral cysts. There is also more focal degeneration and tearing of the articular cartilage of the medial femoral condyle and medial tibial plateau adjacent to the posterior horn of the medial meniscus. There is also moderate degeneration of the articular cartilage of the patellofemoral joint with subchondral cysts in the patella. There are tricompartmental osteophytes.LIGAMENTS: Cruciate and collateral ligaments are intact. EXTENSOR MECHANISM: Extensor mechanism is intact.ADDITIONAL
1.Extensive complex tearing of the lateral meniscus.2.Tricompartmental osteoarthritis.3.Collection of fluid signal intensity along the posteromedial aspect of the proximal tibia which may represent a ganglion or pes anserine bursitis.
