Résumé
Background
Robotic-assisted total hip arthroplasty (RA-THA) may improve component positioning but adds workflow demands during adoption. We evaluated the learning curve for total operative and robotic workflow time during the initial implementation of a CT-based robotic system.
Methods
We retrospectively analyzed 108 consecutive adults undergoing primary RA-THA between January 2024 and June 2025. We recorded skin-to-skin and robotic workflow times for each procedure. Segmented regression was fitted to individual procedure times, with model selection by Bayesian information criterion. We used CUSUM sensitivity analyses and LOESS smoothing to describe time trends.
