| Abstract: | Background: Posterior cruciate ligament (PCL) tear is a severe injury to the knee joint and often requires surgical reconstruction. A number of PCL reconstruction techniques have been reported. However, the problem of residual laxity after surgery is not unusual with conventional techniques. This study aimed to introduce a modified PCL reconstruction with remnant preservation and graft tension relieving.
Methods: Between December 2008 and June 2011, 36 cases of PCL reconstruction were performed in our institute, 20 with conventional technique (Group I) and 16 with modified technique (Group II). Preoperative and postoperative results of IKDC, Lysholm, Tegner and KT2000 side-to-side difference were obtained.
Results: Both groups found significant improvement of IKDC, Lysholm, Tegner and KT2000 results after surgery. Group II showed better improvement in all subjective examinations and significantly more decrease of KT 2000 side-to-side difference.
Conclusions: Modified PCL reconstruction with remnant preservation and graft tension relieving showed better results in restoration of posterior stability compared with conventional technique. |
