The purpose of this study was to investigate the learning curve associated with robotic assisted knee arthroplasty (RAS KA). Therefore, evaluation influence an experienced surgeon on overall team performance three surgeons regarding in RAS KA investigated. It hypothesized that presence flattens and there no inflection point for surgical team.Fifty-five cases consisting 31 total arthroplasties (TKA) 24 unicompartmental (UKA) performed by during 2021 were prospectively Single operation time points investigated using cumulative sum analysis (CUSUM).A downward trend line individual observed. No inflexion observed TKA UKA. all assistance had significantly shorter times than only occasionally received from (p = 0.004 TKA; p 0.002 UKA).The robotically can flatten formerly unexperienced systems. Manufacturers should provide expanded support initial centres without previous experience arthroplasty.III.
