Key Points

To determine whether robotic arm-assisted posterior-stabilized total knee arthroplasty reduces tibial bone resection thickness compared to image-free navigated arthroplasty in patients with varus knee deformities.
Compared robotic arm-assisted posterior-stabilized total knee arthroplasty with image-free navigated total knee arthroplasty in patients with varus knees.
Evaluated short-term outcomes including tibial bone resection thickness, the proportion of minimal thickness insert usage, and the incidence of postoperative flexion contracture.
Robotic arm-assisted total knee arthroplasty reduced the thickness of tibial bone resection compared with image-free navigated arthroplasty.
Robotic assistance increased the rate of minimal thickness insert usage without causing an increase in postoperative flexion contracture.

Implication

Comparative study reveals reduced tibial bone resection and higher minimal insert use in varus knees, suggesting improved bone preservation with robotic arthroplasty.

Abstract

Robotic TKA can reduce the tibial bone resection thickness and increase the rate of minimal thickness insert usage without increasing postoperative flexion contracture as compared with navigated TKA.
