BACKGROUND Current estimates of operative time (OT) for total hip arthroplasty (THA) are reported as the mean OT across all procedures. This method does not reflect variability among surgeons and surgical settings and should not be used to infer individual surgeon work. We hypothesized that this method would underestimate the time it takes individual surgeons to perform THA. Therefore, we compared the mean OT for all THA cases ("overall OT" with the mean OT for individual surgeons ("individual surgeon OT" and examined which factors
