Many have advocated the importance of correcting posterolateral rotatory instability (PLRI) in injuries causing rupture of the posterior cruciate ligament (PCL) and posterolateral corner. However, there have been few studies directly comparing the results of reconstructing the PCL in isolation with PCL reconstruction combined with stabilisation of the posterolateral corner. We report on a retrospective study into 17 consecutive patients with chronic combined posterior cruciate and posterolateral corner ligamentous injuries. The mean follow-up was 35 months (range 14-74 months). All patients had unstable knees, with significant PLRI. In 12 cases the PCL alone was reconstructed, in 5 cases a combined PCL and posterolateral corner reconstruction was performed. At a mean follow-up of 35 months, both groups had significantly improved compared to their pre-operative status, as measured by Lysholm and Tegner scores and clinical examination (P<0.01). The group in which only the PCL was reconstructed had significantly lower scores compared to those who had the additional posterolateral corner reconstruction (Tegner P<0.04, Lysholm P<0.02).
许多人主张在导致后交叉韧带（PCL）和后外侧角破裂的损伤中纠正后外侧旋转不稳定（PLRI）的重要性。然而，很少有研究直接比较单纯重建PCL与PCL重建联合后外侧角稳定的结果。我们报告一项对17例连续性慢性后交叉韧带和后外侧角韧带联合损伤患者的回顾性研究。平均随访时间为35个月（范围14 - 74个月）。所有患者膝关节均不稳定，存在明显的PLRI。12例患者仅重建PCL，5例患者进行了PCL和后外侧角联合重建。在平均35个月的随访中，通过Lysholm和Tegner评分以及临床检查评估，两组患者与术前状态相比均有显著改善（P<0.01）。单纯重建PCL的组与进行了额外后外侧角重建的组相比，评分显著更低（Tegner评分P<0.04，Lysholm评分P<0.02）。
