Background
Robotic-arm assisted total hip arthroplasty (THA) is an emerging technology with potential benefits over traditional manual techniques, though comparative clinical data remain limited.
Methods
This pair-matched controlled study compared outcomes of robotic-arm assisted THA versus manual THA, controlling for demographic and surgical variables. Outcomes included functional scores, pain levels, implant positioning, and complication rates over a minimum 2-year follow-up.
Key Findings
Robotic-assisted THA patients had significantly better Harris Hip Scores and Forgotten Joint Scores, indicating improved function and joint awareness. Implant positioning was more accurate in the robotic group, though pain and overall satisfaction were similar between groups. Revision and complication rates did not differ.
Conclusions
Robotic-arm assisted THA enhances early functional outcomes and implant positioning accuracy compared to manual THA, without increasing complications.
What Does This Mean for Providers?
Surgeons should consider robotic-arm assisted THA to potentially improve implant placement precision and short-term functional outcomes. While pain and satisfaction outcomes are comparable, robotic assistance may optimize surgical reproducibility and joint mechanics.
