Robotic-Assisted Conversion of Unicompartmental Knee Arthroplasty to Total Knee Arthroplasty: A Surgical Technique Review

Abstract

Conversion of a failed unicompartmental knee arthroplasty (UKA) to total knee arthroplasty (TKA) is challenged by asymmetric bone loss necessitating advanced fixation strategies and alignment considerations. Robotic-assisted TKA is an increasingly utilized tool to augment preoperative surgical planning, improve intraoperative execution, and optimize patient outcomes. However, the use of robotic-assisted TKA in conversion UKA is not well described in the literature. We present the authors' preferred surgical technique of conversion UKA utilizing robotic assistance with a haptically guided robotic system and present a case example of a patient managed with this technique.
