[Computed tomography and the pathogenic potential of the medial parapatellar fold].

The anatomy of the synovial folds of the knee joint is described. Autopsy material and the authors' clinical experience are discussed and compared with the literature. CT is superior to conventional arthrography for demonstrating the synovial folds, even when Knutson's technique is used. The morphology of the plica and its relationship to chondropathia of the patella is discussed.
