Surgical Treatment of Extension Contractures Caused by War Injuries to the Knee

Immobilization with external fixation bridging the knee joint in extension is frequently used after sustaining a war injury to the region of the knee joint with femoral and tibial bone fractures. Immobilization of the knee with plaster splints is performed in the same position. This usually prolonged treatment results in extension contractures of the knee joint. From June 1991 until March 1994, 54 patients with extension contractures of the knee caused by war wounds were treated at the Department of Orthopedics, Zagreb University Hospital Center, in Zagreb, Croatia. Results of surgical treatment of 44 patients are presented. The operative procedure consisted of extensive intra- and extra-articular adhesiolysis of the knee. The control group included 30 patients with knee contractures caused by injuries sustained in car crashes or secondary to previous operative procedures. The mean duration of immobilization was 5 months and 6 days. The mean preoperative knee motion amplitude ranged from 5 degrees in extension to 38 degrees in flexion. The mean postoperative knee motion was 98 degrees (range, 2 to 110 degrees). Treatment results did not depend on either duration of preoperative immobilization of the knee or previous infection in the region of injury. Previous knee joint bridging with an external fixator had no impact on the results of extension contracture treatment. Adequate intra- and extra-articular adhesiolysis with appropriate long-term postoperative rehabilitation is essential for the success of the operative treatment for knee joint contracture.
