Arthrography of the knee. II. Isolated and combined lesions

The findings in 1 349 abnormal cases out of 2 836 arhtrographies of the knee have been evaluated statistically. Isolated and combined lesions of menisci, medial collateral and cruciate ligaments have been compared. Type and degree of the individual lesion change with increased complexity of combined injuries. A sequential grading for some lesions has been established. A dominant direction of rupture was found differing in themedial and lateral meniscus. Vertical ruptures anf ruptures of the posterior part of the medial meniscus were positively correlated to more complex injuries.
