The LANCET robotic system can improve surgical efficiency in total hip arthroplasty: A prospective randomized, multicenter, parallel-controlled clinical trial.

研究概要

One hundred sixteen patients with end-stage hip disease were randomized to receive either LANCET robotic arm-assisted total hip arthroplasty (THA) (n=58) or conventional THA (n=58). The primary outcome of interest was the accuracy of acetabular cup placement, measured by the deviation from preoperative planning. Secondary outcomes included operative time, intraoperative bleeding, postoperative hip function recovery, and complication rates. Outcomes were assessed at one week and three months postoperatively. Overall, the results of the study revealed that the LANCET robotic system significantly improved the accuracy of acetabular cup placement, with a higher proportion of patients achieving angles within 5° of the preoperative plan compared to the conventional group. The main findings suggest that the LANCET robotic system enhances surgical precision without increasing complications.
