The number of total knee arthroplasties performed in the United States is growing, and a leading cause of failure is postoperative knee instability from suboptimal coronal or sagittal balancing. This article reviews native knee anatomy as well as several guiding principles of total knee arthroplasty such as limb axis, femoral referencing, and implant constraint. Next, techniques that can be used by the surgeon to achieve ideal sagittal balance and coronal balance are discussed in detail. Finally, due to the growing use of computer and robotic technologies in knee replacement, the impact of advanced technologies on total knee arthroplasty balancing and alignment is reviewed. An in-depth understanding of these topics will enable surgeons to optimize the outcome of their total knee arthroplasty patients.
在美国，全膝关节置换手术的数量正在增加，而手术失败的一个主要原因是冠状面或矢状面平衡欠佳导致的术后膝关节不稳定。本文回顾了膝关节的解剖结构以及全膝关节置换的一些指导原则，如肢体轴线、股骨参考和植入物限制。接下来，将详细讨论外科医生可用于实现理想矢状面平衡和冠状面平衡的技术。最后，由于计算机和机器人技术在膝关节置换中的应用日益广泛，本文将回顾先进技术对全膝关节置换平衡和对线的影响。深入理解这些主题将使外科医生能够优化全膝关节置换患者的手术效果。
