To determine whether there is a consistent extension of the lateral synovial recess under the iliotibial band (ITB) in an unembalmed cadaveric model. ⋯ The lateral synovial recess appears to regularly extend beneath the anterior ITB. Fluid deep to the ITB should precipitate further evaluation of the knee joint when clinically indicated. Although distention of the lateral synovial recess is not always symptomatic, synovial irritation may be a pathoetiologic factor in the production of lateral knee pain syndromes, including ITB syndrome.
