About

Nicholas J. Dunbar is a leading orthopaedic researcher whose work centers on the precision and accuracy of joint arthroplasty, with a particular focus on unicompartmental knee and total hip replacements. His major contributions lie in evaluating the efficacy of advanced surgical technologies—specifically robotic and haptic guidance systems—against conventional techniques. In his landmark 2012 study, Dunbar demonstrated that robotic technology significantly improves the accuracy of unicompartmental knee arthroplasty (150 citations), a finding reinforced by his earlier work on dynamic tactile-guided procedures (135 citations). His cadaveric investigation into haptically guided robotics for total hip arthroplasty (116 citations) further underscored the potential of these systems to reduce complications like dislocation and impingement, which often stem from suboptimal component orientation. Collectively, Dunbar’s research has provided compelling evidence that robotic assistance can enhance surgical precision, offering a pathway to improved implant longevity and patient outcomes. His work is widely cited and has helped shape the ongoing integration of robotics into orthopaedic surgery.
