Total Hip Replacement: an Investigation of Robotic-assisted Versus conVentional Surgery and Patient-centred outcomEs

In the researchers' words

Hip replacement is highly effective for severe osteoarthritis, but some patients continue to experience symptoms or complications. Robotic-assisted hip replacement uses three-dimensional planning and robotic guidance to position implants more precisely. Although its use is increasing, it remains uncertain whether this added precision improves recovery or outcomes that patients can feel. We will conduct an internal pilot randomized trial of adults undergoing hip replacement at Juravinski Hospital. Participants will be assigned by chance to robotic-assisted or conventional surgery. The pilot will assess recruitment, delivery of assigned surgery, protocol adherence, follow-up and data quality to determine whether a larger Canadian multicentre trial is feasible. We will also collect joint awareness, function, quality of life, satisfaction, complications, operating time, length of stay and readmission. If progression criteria are met, pilot participants and data will be retained in the expanded trial. This study will build the Canadian evidence needed to evaluate robotic-assisted hip replacement responsibly.
