About

Martin Underwood is a leading orthopaedic researcher whose work centers on evaluating the effectiveness of robotic-assisted surgery in total hip and knee arthroplasty. His major contribution lies in designing and leading the RACER (Robotic Arthroplasty Clinical and cost Effectiveness Randomised controlled trial) program—a landmark series of studies that rigorously assess whether robotic-arm systems deliver superior clinical outcomes and value for money compared to conventional joint replacement. By focusing on robust, randomised evidence, Underwood addresses a critical gap in a field where high-tech adoption has often outpaced proof of benefit. His most-cited paper, “Robotic trials in arthroplasty surgery” (2024, 22 citations), synthesises the rationale for such trials, while his detailed protocols for RACER-knee (2023, 17 citations) and RACER-Hip (2023, 5 citations) set the standard for methodological transparency. Underwood’s work directly informs surgical decision-making and healthcare policy, challenging assumptions that added cost and precision automatically translate to better patient outcomes. For students and researchers, his career exemplifies how pragmatic, high-quality trial design can bring clarity to a rapidly evolving surgical landscape.
