Pilot study comparing operating room workflow and team ergonomics in robotic-assisted versus navigated total knee arthroplasty

Aubert, Thomas et al. · SICOT-J · 2026

This retrospective study compared the VELYS robotic-assisted solution (VRAS) with computer-navigated total knee arthroplasty (TKA) in 20 patients. The results showed that robotic-assisted TKA did not increase overall operating room time, while reducing skin-to-skin time and significantly lowering surgeon workload and physical strain.

Surgeons reported lower mental, physical, and temporal demands with VRAS, alongside improved perceived performance. Objective ergonomic measures also showed reduced power tool, retractor, and leg holding times, suggesting potential workflow and ergonomic advantages for robotic-assisted TKA.
