Symptomatic genu recurvatum, defined as knee hyperextension beyond 5° with symptoms of pain or instability, is uncommon and presents a challenging treatment paradigm for orthopaedic surgeons. Treatment options focus on initial nonoperative management with bracing and physical therapy focused on correcting gait abnormalities and strengthening dynamic stabilizers, addressing soft-tissue laxity via posterior capsular tensioning/imbrication, and correcting osseous abnormalities with anterior opening-wedge proximal tibial osteotomies. In cases in which there are minimal bony abnormalities contributing to recurvatum, such as posterior tibial slope, posterior capsular imbrication is indicated. There is a lack of both technical and outcome literature on posterior capsular imbrication; thus, the purpose of this technical note is to describe our technique for performing a modern arthroscopic posterior capsular imbrication for dynamic genu recurvatum.
症状性膝反屈，定义为膝关节过伸超过5°且伴有疼痛或不稳定症状，较为少见，给骨科医生带来了具有挑战性的治疗模式。治疗选择集中在初始的非手术治疗，包括使用支具以及针对纠正步态异常和加强动态稳定器的物理治疗，通过后关节囊拉紧/重叠缝合解决软组织松弛问题，以及通过胫骨近端前侧开放楔形截骨矫正骨异常。在导致膝反屈的骨异常（如胫骨后倾）较少的情况下，应进行后关节囊重叠缝合。目前关于后关节囊重叠缝合的技术和疗效文献都很缺乏；因此，本技术说明的目的是描述我们为动态膝反屈进行现代关节镜下后关节囊重叠缝合的技术。
