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 aims to introduce a modified PCL reconstruction with remnant preservation and graft tension relieving.
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). Pre- and post-operative results of the international knee documentation committee knee evaluation form (IKDC), Lysholm, Tegner, and KT2000 side-to-side difference were obtained.
Significant improvements of IKDC, Lysholm, Tegner, and KT2000 results after surgery were found in both groups. Group II showed better improvement in all subjective examinations and significantly more decrease of KT 2000 side-to-side difference.
Modified PCL reconstruction with remnant preservation and graft tension relieving showed better results in restoration of posterior stability compared to conventional technique.
后交叉韧带（PCL）撕裂是膝关节的严重损伤，常需要手术重建。已经报道了许多 PCL 重建技术。然而，传统技术手术后残余松弛并不罕见。本研究旨在介绍一种改良的 PCL 重建技术，保留残端并缓解移植物张力。
2008 年 12 月至 2011 年 6 月，我院共进行了 36 例 PCL 重建，其中常规技术 20 例（I 组），改良技术 16 例（II 组）。采用国际膝关节文献委员会膝关节评估表（IKDC）、Lysholm、Tegner 和 KT2000 侧间差值对术前和术后结果进行评估。
两组患者的 IKDC、Lysholm、Tegner 和 KT2000 结果均有显著改善。II 组在所有主观检查中改善更好，KT2000 侧间差值明显降低。
与传统技术相比，保留残端并缓解移植物张力的改良 PCL 重建技术在恢复后向稳定性方面效果更好。
