[Radiological and histological aspects of changes in the knee joint(author's transl)].

A comparison was carried out between histological and arthrographic findings which resulted in a revision in the interpretation of certain radiological signs. Meniscus lesions, osteochondrosis dissecans, chondrosis dissecans and synovitis are considered histologically and radiologically. Dengenerative reactions which can be demonstrated radiologically (irregular margins) consist of mucoid degeneration, trabecular changes, fatty degeneration and oedema of the ground substance. The agreement between arthrographic and histological findings is not unexpected, since both methods demonstrate morphology by different means.
