Introduction of ROSA robotic‐arm system for total knee arthroplasty is associated with a minimal learning curve for operative time

The introduction of the RA TKA system was associated with a learning curve for operative time of 8.7 cases. Operative times between the RA TKA and conventional TKA group were similar. The short learning curve implies this RA TKA system can be adopted relatively quickly into a surgical team with minimal risks to patients.
