Compares surgical complications of technology-assisted and manual hip arthroplasty, suggesting improved safety with technology-assisted methods.
Background: Utilization of technology-assisted total hip arthroplasty (TA-THA) with computer navigation or robotic assistance continues to increase in the United States. This study aims to provide an updated examination of the trends and patient factors associated with TA-THA and compare postoperative surgical complications between TA-THA and manual THA (M-THA). Methods: < .05) and odds ratios (ORs). Results: < .001). At 3-year follow-up, M-THA was associated with higher odds of all-cause revision (OR: 1.28), dislocation (OR: 1.43), deep infection (OR: 1.45), and aseptic loosening (OR: 1.38). In contrast, M-THA exhibited a lower risk of superficial infection (OR: 0.65). No significant difference was observed for the incidence of periprosthetic fractures. Conclusions: The utilization of TA-THA has more than doubled over the past decade, with notable regional and institutional differences. Compared to M-THA, TA-THA was associated with a decreased risk of multiple postoperative complications over a 3-year period. Further studies will be needed to determine whether this technology should be widely adopted by general orthopaedic surgeons performing THA or if it will primarily serve as a tool for arthroplasty surgeons seeking enhanced efficiency and precision.
