Comparing clinical and radiographic outcomes of robotic-assisted, computer-navigated and conventional unicompartmental knee arthroplasty: A network meta-analysis of randomized controlled trials.

INTRODUCTION: The purpose was to compare robotic assisted (RA), computer navigated (CN), and conventional UKA techniques. METHODS: Databases were queried for data on study characteristics, UKA systems, complications, and tibiofemoral alignment. RESULTS: Four RA and six CN RCTs were identified. No significant differences were found in operative time, tibiofemoral alignment, and reoperation rates when comparing RA or CN to conventional UKA. RA UKA resulted in a significantly lower risk of complications compared to conventional UKA. CONCLUSIONS: RA UKA results in fewer complications than conventional UKA with a clinically significant increase in operative time. All groups were similar in remaining evaluated parameters.
