[Double contrast arthrography as a screening method of suspected meniscal lesions].

On reevaluation after one year of experience with double-contrast-arthrography (DCA) we found in 83 consecutive patients with suspected meniscal lesion a true positive diagnostic frequency of 0.84, a true negative diagnostic frequency of 0.75, a true positive nosografic frequency of 0.87 and a true negative nosografic frequency of 0.70. This gives an increased diagnostic accuracy compared to the initial evaluation of the arthrografies. No complications of the examination were registered. As DCA demands fewer resources than arthroscopy, this method is suggested as a screening procedure in patients with possible tears of the menisci.
