Current evidence base for kinematic alignment.

Abstract

Kinematic alignment recently became an alternative alignment option for total knee arthroplasty (TKA). Beside previous studies assessing mechanical alignment in comparison to unintentional malalignment of TKA in terms of implant survival and clinical outcome, more and more studies have focused on the direct comparison of intentional kinematic alignment with mechanical alignment of the prosthesis. In the past 5 years the number of studies with respect to kinematic alignment has risen from 11to 91studies. The aim of this review article is to give anarrative overview of the current literature in the debate concerning kinematic and mechanical alignment in TKA.
