人们认为，最佳植入物对准等依赖于外科医生的因素对初次全膝关节置换术 (TKA) 的结果起着重要作用。然而，最佳对齐的确切定义和参考仍在争论中。本文献概述描述了初次 TKA 后组件对准的不同定义，包括 (1) 在 AP 平面中的胫骨股骨对准，(2) 在 AP 平面中的胫骨和股骨组件放置，(3) 在矢状平面中的胫骨和股骨组件放置，以及 (4) 胫骨和股骨组件的旋转对准及其在结果和植入物存活中的作用。我们对初次 TKA 后种植体定位的原始文章和评论文章进行了文献检索。总结了股骨和胫骨假体的冠状、矢状和旋转放置的定义，并考虑了放置对生存和功能结果的影响。在评估股骨和胫骨组件的放置时存在许多定义。植入物对准对于初次全膝关节置换术后的生存和功能结果都起着重要作用，因为组件对准不良会导致失败率增加、跟踪不良和膝盖疼痛。根据目前现有的证据，外科医生在进行 TKA 时应以胫骨和股骨组件的最佳对齐为目标。
Surgeon-dependent factors such as optimal implant alignment are thought to play a significant role in outcome following primary total knee arthroplasty (TKA). Exact definitions and references for optimal alignment are, however, still being debated. This overview of the literature describes different definitions of component alignment following primary TKA for (1) tibiofemoral alignment in the AP plane, (2) tibial and femoral component placement in the AP plane, (3) tibial and femoral component placement in the sagittal plane, and (4) rotational alignment of tibial and femoral components and their role in outcome and implant survival. We performed a literature search for original and review articles on implant positioning following primary TKA. Definitions for coronal, sagittal, and rotational placement of femoral and tibial components were summarized and the influence of positioning on survival and functional outcome was considered. Many definitions exist when evaluating placement of femoral and tibial components. Implant alignment plays a role in both survival and functional outcome following primary TKA, as component malalignment can lead to increased failure rates, maltracking, and knee pain. Based on currently available evidence, surgeons should aim for optimal alignment of tibial and femoral components when performing TKA.
