Total Knee Replacement: Robotic Assistive Technique

Abstract

Abstract Total knee replacement (TKR) has become the standard procedure in the management of degenerative joint disease after more conservative therapy options have been exhausted. However, despite conscientious planning and carefully performed procedures, surgeons are often unsatisfied with implant alignment. Various authors described significant axial or rotational malalignment, and mediolateral and ventrodorsal tilt.1–4 Seemingly small displacements of 2.5 mm potentially alter the range of motion by as much as 20°.5 Correct tibiofemoral alignment seems to be particularly important since it is generally agreed that axial deviation and imprecise implantation may lead to early loosening of implant components.
