To highlight current and established concepts regarding PCL injury and reconstruction.
Recent biomechanical and clinical studies have brought attention to improved surgical techniques and clinical outcomes of PCL reconstruction. In contrast to anterior cruciate ligament (ACL) injuries, isolated posterior cruciate ligament (PCL) injuries occur much less frequently and have traditionally been treated non-operatively. Even when a PCL injury meets operative indications, outcomes of PCL reconstruction historically do not match the success rates of ACL reconstruction procedures. As such, there remains controversy regarding appropriate indications and techniques for surgical repair leading to a paucity of conclusive data regarding surgical outcomes. Recently, however, there has been an increase in focus on the role of the PCL in proper knee biomechanics and negative long-term sequelae of chronic PCL insufficiency. This improved understanding has led to advancements in surgical technique and graft options for PCL reconstruction.
强调关于后交叉韧带(PCL)损伤与重建的现有及新出现的概念。
近期的生物力学和临床研究已将注意力引向PCL重建手术技术的改进及临床结果。与前交叉韧带(ACL)损伤不同,孤立性后交叉韧带(PCL)损伤发生频率低得多,传统上采用非手术治疗。即便PCL损伤符合手术指征,PCL重建的历史结果也比不上ACL重建手术的成功率。因此,关于手术修复的合适指征和技术仍存在争议,导致关于手术结果的确凿数据匮乏。然而,近来对PCL在膝关节正常生物力学中的作用以及慢性PCL功能不全的长期不良后果的关注有所增加。这种认识的提高推动了PCL重建手术技术和移植物选择的进步。
