About

Sophie Rees is a leading clinical trialist whose work is reshaping the evidence base for robotic-assisted joint replacement. Her primary research focuses on the clinical and cost-effectiveness of robotic arthroplasty for knees and hips, addressing a critical gap in orthopaedic surgery. Rees is the lead author of the landmark RACER-knee and RACER-Hip study protocols, which together have garnered over 20 citations. These trials are among the first to rigorously evaluate whether robotic-arm systems—despite their high costs—truly improve surgical precision and patient outcomes compared to conventional methods. By designing large-scale, randomised controlled trials, Rees is providing the high-quality evidence needed to guide healthcare policy and surgical practice worldwide. Her work challenges the assumption that technological advancement automatically translates to better care, emphasising the need for robust data. For students and researchers, Sophie Rees exemplifies how methodical trial design can answer pressing questions in modern surgery, ensuring that innovation is both clinically effective and economically sustainable.
