Clinical outcome after reconstruction for isolated posterior cruciate ligament injury.
Fifty-one patients were operated with reconstruction for an isolated PCL injury from 1997 to 2005. Forty-three of these patients were followed during a median period of 48 months (17-109). Median time from injury to surgery was 18 months (2-368). Five patients were operated within the first 6 months after the injury. Nineteen patients had a BPTB autograft, 24 had a hamstring tendon autograft, and seven patients in the hamstring group had a double-bundle femoral fixation. Clinical assessment included Lysholm knee score, International Knee Documentation Committee 2000 (IKDC) scores, Cincinnati score, Tegner score, KOOS score, VAS score, stress radiographs, and a functional test. The median Lysholm score at follow-up was 80 (32-95). Median Tegner score before injury was 7 (1-10) and at follow-up 6 (0-9). Median Cincinnati and IKDC 2000 scores were 74 (12-100) and 63 (24-100), respectively. The mean VAS for subjective assessment of knee function was 67.6 (SD = 22.9). The radiologically measured difference in posterior tibial translation between operated and non-injured knees was mean 8.4 mm (SD =4.8). Four different functional tests showed function of the operated leg from 92% (25-128) to 95% (15-124) compared to the opposite leg. This study shows good functional outcome after reconstruction for isolated rupture of the posterior cruciate ligament. However, pain and instability are still a problem, as only three patients reported full Lysholm subscore indicating full stability, and only four patients reported full subscore indicating no knee pain.
