Overview

The goal of this RCT is to investigate efficacy between restricted kinematic alignment and mechanical alignment TKA in simultaneous bilateral TKA patients.

The main question[s] it aims to answer are:

  • Does rKA have better functional outcomes than MA in simultaneous bilateral TKA patients?
  • Does rKA have lower pain score than MA in simultaneous bilateral TKA patients? Participants will undergo simultaneous bilateral TKA and randomized one side will use rKA and the other side will use MA.
