The advantages of UKA include bone stock preservation, physiologic kinematics, retention of main knee ligaments, improved proprioception, & better functional outcome. A semi-active robotic system using CT-based data combined with intraoperative registration & tactile feedback has the potential for more precise implant placement & alignment. This purpose of this study was to compare robotic-assisted implantation (RAI) with conventional manual implantation (CMI) & to investigate whether this technology could lead to more reliable & reproducible outcomes. We prospectively collected data on 32 RAI UKR and 30 CMI UKR. Baseline data collection included: age, gender, BMI, comorbidities, diagnosis, & pre-operative SF-12 Physical Component, SF-12 Mental Component, WOMAC pain, WOMAC Stiffness, & WOMAC Physical Functional scores. Postoperatively, SF-12 & WOMAC scores were recorded, in addition to routine arthroplasty follow-up.Introduction
