Recent studies have challenged the long-held notion that neutral mechanical alignment after total knee arthroplasty leads to optimal function and survivorship.The ideal alignment for function and survivorship may actually be different.Kinematic alignment, where components are implanted to re-create the natural flexion/extension axis of the knee, may lead to improved functional results.Residual varus alignment may not adversely impact survivorship provided the tibial component is implanted in neutral alignment.

近期研究对长期以来的观念提出了挑战,该观念认为全膝关节置换术后中立位机械对线可带来最佳功能和假体生存率。实际上,功能和假体生存率的理想对线可能有所不同。运动学对线是指植入假体部件以重建膝关节自然屈伸轴,这可能会带来更好的功能结果。只要胫骨部件植入中立位对线,残余内翻对线可能不会对假体生存率产生不利影响。引用本文:洛丁 T,卢斯蒂格 S,内雷 P。全膝关节置换术后的冠状面排列。2016;1:12 - 17。doi:10.1302/2058 - 5241.1.000002 。
