Key takeaways:
- Robotic and conventional total hip arthroplasty had no statistically significant differences in outcome measures.
- Robotic total hip arthroplasty trended toward higher Forgotten Joint Scores.
LAS VEGAS — Results presented at the American Academy of Orthopaedic Surgeons Annual Meeting showed robotic total hip arthroplasty may have similar functional outcomes compared with conventional THA.
Andreas Fontalis, MD, MSc, MRCS, and colleagues collected the Oxford Hip Score, the University of California Los Angeles Hip Score and Forgotten Joint Score preoperatively and at a minimum 3-year follow-up among 100 patients who underwent either conventional (n=50) or robotic (n=50) THA.
At 3-year follow-up, Fontalis noted no statistically significant differences between the conventional and robotic THA groups with regard to patient-reported outcome measures. He added patients in the robotic THA group had a trend toward higher Forgotten Joint Scores, which did not reach statistical significance. Results showed no statistical correlation between accuracy of achieving the planned cup inclination and version with the patient-reported outcome measures, according to results using Spearman’s rank correlation coefficient.
“Results from trials conducted in a randomized controlled setting will be key and, in this vein, we have completed recruitment on a prospective [randomized controlled trial] RCT and we are currently analyzing the results,” Fontalis said.
