Coronal alignment after total knee arthroplasty

Abstract

▪ 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.
