[Examinations with the KT-1000 knee arthrometer in injuries of the posterior cruciate ligament in comparison with stress roentgen images in the Scheuba positioning device].

Eighteen patients with surgically treated ruptures of the posterior cruciate ligament were tested on follow-up 2 to 13 years with KT-1000 Kneearthrometer and radiologically according to Scheuba to objectify the clinical results and to compare the 2 methods. It could be shown that both methods are highly specific and do correspond in 89%. In 11% a borderline difference between a "+" posterior drawer and a "++" posterior drawer in the classification by Hughston et al. [5] was detected. Since the Scheuba test does involve radiation, the KT-1000 Knee-arthrometer testing device represents a safe alternative to objectify a posterior drawer.
