Reason: eval knee History: pain MENISCI: There is attenuation of the posterior horn of the lateral meniscus compatible with prior partial meniscectomy. There is increased signal intensity at the interface of the meniscofemoral ligament of Wrisberg with the posterior horn which could represent the remnants of a "Wrisberg rip", but this does not appear to have progressed when compared to the prior study. There is linear increased signal intensity within the body of the lateral meniscus extending to the femoral articular surface, seen on a single image, that has a low likelihood of representing a true tear. The medial meniscus appears intact.ARTICULAR CARTILAGE AND BONE: STIR sequences were substituted for fat-saturated T2-weighted images to reduce metal artifact. This decreases our ability to assess the articular cartilage. Subjectively, the articular cartilage of the patella appears thinned suggesting degeneration, but we see no full-thickness cartilage defects. There is mild edema type signal within the anterior aspect of the proximal tibia that is nonspecific. We see no fracture.LIGAMENTS: The patient has undergone ACL reconstruction. The graft appears intact. There is focal low signal intensity anterior to the intra-articular portion of the graft likely representing focal fibrosis. The PCL appears intact. The patient has undergone MCL reconstruction. The MCL itself appears intact, although thickened, likely reflecting adjacent scar tissue. The LCL appears intact.EXTENSOR MECHANISM: The extensor mechanism appears intact.ADDITIONAL
1. Surgical changes of ACL and MCL reconstruction and prior partial lateral meniscectomy.2. Mild nonspecific subcutaneous edema within the anterior and anteromedial aspect of the knee.3. Mild subjective thinning of the patellar cartilage and other findings as described above.
