About

Matthias Haselbacher is a leading figure in orthopedic robotics, specializing in the intersection of surgical automation and minimally invasive techniques. His core research focuses on developing robotic systems to enhance precision and reduce trauma in joint replacement surgeries, particularly hip arthroplasty. Haselbacher’s most notable contribution is his pioneering work on semiactive retractor holders, which replace human assistants in soft tissue retraction during minimally invasive procedures. In a landmark 2015 cadaver study, he demonstrated that robotic retraction achieves comparable or superior stability and tissue handling to manual assistance, a finding that has garnered 9 citations and laid groundwork for safer, more consistent surgical outcomes. This innovation addresses a critical bottleneck in hip arthroplasty—reducing variability in retraction forces that can lead to iatrogenic injury. Beyond this, Haselbacher’s research portfolio explores broader applications of robotic assistance in orthopedics, aiming to standardize complex maneuvers and shorten recovery times. His work is instrumental in advancing the field toward autonomous surgical support, where robots not only guide instruments but actively participate in tissue management. For students and researchers, Haselbacher exemplifies how targeted engineering solutions can transform traditional surgical workflows, offering a blueprint for integrating robotics into everyday clinical practice.
