Leg positioner improves efficiency on selected steps in robotic-assisted total knee arthroplasty: an analysis of surgical workflow efficiency and team experience

= 0.027). Questionnaires indicated high satisfaction overall, though surgeons reported reduced ease of robotic arm operation and confidence in ligament balancing. The leg positioner redistributed time across surgical steps rather than improving overall efficiency. It offers stability benefits but may restrict intraoperative flexibility. Further studies should address ergonomics, cost-effectiveness, and long-term outcomes.
