Successful total knee arthroplasty (TKA) has often been based on the restoration of the knee to neutral alignment postoperatively. Numerous reports have linked malaligned TKA components to increased wear, poor functional outcomes, and failure. There have been many different alignment philosophies and surgical techniques that have been established to attain the goal of proper alignment, which includes such techniques as computerized navigation, and custom cutting guides. In addition, these methods could potentially have the added benefit of leading to improved functional outcomes following total knee arthroplasty. In this report, we have reviewed and analyzed recent reports concerning mechanical, anatomic, and kinematic axis/alignment schemes used in total knee arthroplasty.
成功的全膝关节置换术(TKA)通常基于术后膝关节恢复到中立对线。大量报告将 TKA 组件对线不良与增加的磨损、不良的功能结果和失败联系起来。已经有许多不同的对线理念和手术技术被确立,以达到适当对线的目标,其中包括计算机导航和定制切割导向器等技术。此外,这些方法可能具有潜在的额外益处,可改善全膝关节置换术后的功能结果。在本报告中,我们回顾和分析了最近关于全膝关节置换术中使用的机械、解剖和运动学轴/对线方案的报告。
