High-grade posterior cruciate ligament (PCL) tears can be a significant cause of patient morbidity and knee instability. The graft of choice for operative repair remains controversial, although recently there has been increased interest in quadriceps tendon (QT) as an autologous graft option.
The purpose of this study was to perform a systematic review to assess reported clinical outcomes of PCL reconstructions using QT autografts.
A comprehensive review of clinical studies was performed evaluating PCL reconstruction with QT autograft including a systematic search of PubMed, Scopus, Cochrane and Google Scholar databases, and reference lists of relevant papers. Clinical results, stability results, functional outcomes, range-of-motion outcomes, complications and morbidity, and the conclusions of each study were evaluated.
Seven studies were included in the review of clinical results, including 145 subjects undergoing PCL reconstructions with QT autograft. All studies evaluated quadriceps tendon bone (QT-B) grafts. Among these seven studies, two included isolated PCL reconstruction while five included multiligamentous knee injury reconstruction. These studies suggest that QT-B autograft offers a viable graft option for primary PCL reconstruction with generally favourable patient-reported outcomes, knee stability and range of motion reported along with relatively low complication rates.
Use of the QT-B autograft may be a reasonable graft option for PCL reconstruction. However, high-quality prospective studies are required to evaluate the long-term safety, efficacy and functional outcomes.

高等级后交叉韧带（PCL）撕裂可能是导致患者发病和膝关节不稳定的重要原因。对于手术修复，首选的移植物仍然存在争议，尽管最近人们对股四头肌肌腱（QT）作为自体移植物选择的兴趣有所增加。
本研究旨在进行系统评价，评估使用 QT 自体移植物重建 PCL 的报告临床结果。
对包括 PubMed、Scopus、Cochrane 和 Google Scholar 数据库以及相关论文参考文献的全面检索，评估了包括 QT 自体移植物的 PCL 重建的临床研究，评估了临床结果、稳定性结果、功能结果、活动范围结果、并发症和发病率以及每个研究的结论。
共有 7 项临床结果研究被纳入综述，包括 145 例接受 QT 自体移植物重建 PCL 的患者。所有研究均评估了四头肌腱骨（QT-B）移植物。在这 7 项研究中，2 项研究包括单纯 PCL 重建，5 项研究包括多韧带膝关节损伤重建。这些研究表明，QT-B 自体移植物是一种可行的 PCL 重建移植物选择，通常具有良好的患者报告结果、膝关节稳定性和活动范围，以及相对较低的并发症发生率。
使用 QT-B 自体移植物可能是 PCL 重建的合理移植物选择。然而，需要高质量的前瞻性研究来评估长期安全性、疗效和功能结果。
