About
William J. Hozack is a prominent orthopedic surgeon and researcher whose work has substantially shaped the evolution of technology-assisted joint replacement surgery, with a particular focus on robotic-arm-assisted total knee and hip arthroplasty. His research consistently examines whether emerging surgical technologies translate into measurable improvements for patients, addressing critical questions around component placement accuracy, patient-reported outcomes, complication rates, and cost-effectiveness within modern bundled payment models. Among his most influential contributions, Hozack led and participated in prospective multicenter investigations demonstrating that robotic-arm-assisted total knee arthroplasty (RATKA) yields superior component positioning accuracy and improved early patient satisfaction compared to conventional techniques—findings that have collectively garnered over 300 citations. His work extends beyond the operating room, exploring practical recovery milestones such as return to work and driving following RATKA, as well as dislocation risk reduction in robotic-assisted total hip arthroplasty across multiple surgical approaches. Hozack's research reflects a rigorous, outcomes-driven philosophy: embracing innovation while demanding evidence of clinical and economic value. By addressing both short- and medium-term outcomes with minimum two-year follow-up analyses, he has helped establish an evidence base that guides adoption of robotic surgery in orthopedics, making his work essential reading for surgeons and researchers navigating the rapidly evolving landscape of joint replacement technology.
