[The reliability of arthrography of the knee joint via medium format technique (author's transl)]

Reports on 217 arthrographies of the knee joint with operative control. Partly or entirely erroneous roentgen diagnoses were made in 4.8-16.3% of the cases, depending upon the technique by which the patients had been examined. Lateral meniscus lesion was wrongly diagnosed three times as often as the medial lesion. The lowest incidence of wrong diagnoses occurred when examining via the medium format technique.
