PURPOSE The management of posterolateral corner (PLC) injuries has significantly evolved over the past 2 decades. The purpose of this study was to determine the current worldview of key concepts on the diagnosis, treatment strategy, and rehabilitation for patients presenting with PLC injuries. METHODS A 12-question multiple-choice online survey was designed to address key questions in the diagnosis, treatment, and rehabilitation of PLC injuries. The survey was distributed to the most important international sports medicine societies worldwide. Clinical agreement was defined as > 80% of agreement in responses and general agreement was defined as > 60% of agreement in responses. RESULTS 975 surgeons completed the survey with 49% from Europe, 21% from North America, 12% from Latin America, 12% from Asia, and smaller percentages from Africa and Oceania. Less than 14% of respondents manage more than ten PCL injuries yearly. Clinical agreement of > 80% was only evident in the use of MRI in the diagnosis of PLC injury. Responses for surgical treatment were split between isometric fibular-based reconstruction techniques and anatomically based fibular and tibial-based reconstructions. A general agreement of > 60% was present for the use of a post-operative brace in the early rehabilitation. CONCLUSION In the global surgical community, there remains a significant variability in the diagnosis, treatment, and postoperative management of PLC injuries. The number of PLC injuries treated yearly by most surgeons remains low. As global clinical consensus for PLC remains elusive, societies will need to play an important role in the dissemination of evidence-based practices for PLC injuries. LEVEL OF EVIDENCE IV.

在全球外科手术社区中，后外侧角损伤的处理存在很大差异。

目的在过去的20年中，后外侧角（PLC）损伤的处理有了很大的发展。这项研究的目的是确定当前存在PLC损伤的患者的诊断，治疗策略和康复关键概念的世界观。方法设计12个问题的多项选择的在线调查，以解决PLC损伤的诊断，治疗和康复中的关键问题。该调查已分发给全球最重要的国际运动医学会。临床同意被定义为> 80％的反应同意，而一般同意被定义为> 60％的60％回应同意。结果975位外科医生完成了调查，其中49％来自欧洲，21％来自北美，12％来自拉丁美洲，12％来自亚洲，而来自非洲和大洋洲的比例更低。每年不到14％的受访者管理十多件PCL伤害。仅在使用MRI诊断PLC损伤中才有超过80％的临床一致性。手术治疗的反应分为基于等距腓骨的重建技术和基于解剖学的腓骨和胫骨的重建。对于在早期康复中使用术后支架，普遍同意> 60％。结论在全球外科界，PLC损伤的诊断，治疗和术后处理仍存在很大差异。大多数外科医生每年治疗的PLC损伤数量仍然很少。由于PLC的全球临床共识仍然难以捉摸，社区将在传播PLC伤害的循证实践中发挥重要作用。证据级别IV。
