Minimum 5-Year Outcomes of Robotic-assisted Primary Total Hip Arthroplasty With a Nested Comparison Against Manual Primary Total Hip Arthroplasty: A Propensity Score-Matched Study
Authors: Domb BG, Chen JW, Lall AC, Perets I, Maldonado DR
Background
Robotic-assisted technology aims to improve accuracy in acetabular cup placement during total hip arthroplasty (THA). This study compares 5-year clinical outcomes of robotic-assisted THA (rTHA) with manual THA (mTHA).
Methods
Sixty-six patients who underwent rTHA were matched with 66 patients who underwent mTHA. Outcomes including Harris Hip Score, Forgotten Joint Score, and leg length discrepancy were assessed at a minimum of 5 years post-op.
Key Findings
- rTHA patients had significantly better functional scores and less leg length discrepancy.
- The risk of improper acetabular cup placement was markedly reduced with robotic assistance.
Conclusions
Robotic-assisted THA provides superior precision and clinical outcomes compared to manual THA, reducing the risk of malposition-related complications.
What Does This Mean for Providers?
Incorporating robotic-assisted technology in THA may enhance surgical accuracy, improve functional outcomes, and reduce postoperative complications related to implant positioning. Providers should consider robotic assistance as a valuable tool for hip arthroplasty, particularly in complex cases.
