Abstract

Robotic total knee arthroplasty (R-TKA) adoption continues to expand, yet most learning curve analyses focus on global operative time rather than individual procedural steps. The TMINI system is a handheld, imageless robotic platform with limited published data. We evaluated step-specific learning curves in a single surgeon's first 75 consecutive cases with complete intraoperative timing data. We…
