Reason: left knee pain, evaluate for medial meniscus tear, chondral damage History: left knee pain MENISCI: There is mild intrasubstance degeneration of the posterior horn of the medial meniscus along with very mild surface irregularity along the undersurface fibers near the free edge likely representing fraying, but we see no fluid-filled or unstable-appearing tear. There is intrasubstance degeneration of the body of the meniscus as well. The anterior horn appears intact. There is minimal intrasubstance degeneration of the lateral meniscus which otherwise appears intact.ARTICULAR CARTILAGE AND BONE: There is near full-thickness to full-thickness degeneration of the articular cartilage of the patella along the median eminence and medial facet with underlying degenerative subchondral signal abnormality. There is also perhaps mild thinning of the articular cartilage of the lateral facet of the patella and femoral trochlea. There is focal full-thickness degeneration of the articular cartilage of the lateral tibial plateau, posteriorly, with degenerative signal abnormality in the underlying subchondral bone. The medial compartment articular cartilage appears relatively preserved.LIGAMENTS: The cruciate and collateral ligaments appear intact. EXTENSOR MECHANISM: The extensor mechanism appears intact.ADDITIONAL
1. Cartilage degeneration particularly affecting the undersurface of the patella. The medial compartment cartilage appears relatively spared.2. Mild intrasubstance degeneration of the menisci and possible fraying of the posterior horn of the medial meniscus, but no fluid-filled or unstable tear is evident.3. Mild edema within the lateral head of the gastrocnemius may represent a strain.
