[Reliability of double-contrast arthrography in detection of cartilage lesions of the knee joint (author's transl)].

The present work evaluates the method of double-contrast arthrography. To this end, cartilage damage on femoral condyles and tibial joint surfaces was studied in 1566 retrospectively evaluated double-contrast arthrographies. Operation reports and histological results served as control. The results of our own experiments demonstrate that even isolated cartilage lesions as small as 1 mm in diameter can be visualized.
