Tendency of Tibial Component Placement and Short-Term Outcomes in ROSA-Assisted Unicompartmental Knee Arthroplasty Using the Persona Partial Knee System.

ABSTRACT:

Background

Robot-assisted unicompartmental knee arthroplasty (UKA) has been introduced to improve component positioning. The ROSA Knee System and Persona Partial Knee (Zimmer Biomet, Warsaw, IN, USA) constitute a relatively new robotic platform with limited data. We aimed to quantify tibial and femoral component alignment and evaluate short-term clinical outcomes.

Methods

We reviewed 64 consecutive medial UKAs performed with this system. Preoperative planning used computed tomography (CT)-based three-dimensional models. Postoperative component alignment was measured on radiographs and CT. Clinical outcomes were assessed with the 2011 Knee Society Score (KSS) preoperatively and at 1 year; paired analyses were performed in 34 knees with complete preoperative and postoperative
