About
David A. Gregory is a leading health outcomes researcher specializing in the comparative effectiveness and economic value of robotic-assisted orthopedic surgery. His work focuses on total knee and total hip arthroplasty, where he rigorously evaluates how robotic-arm assistance impacts patient outcomes, health care utilization, and payer costs. Gregory’s most influential study, with 48 citations, demonstrated significant reductions in 30-, 60-, and 90-day health care utilization and costs for robotic-assisted total knee arthroplasty compared to manual techniques. He extended this analysis to total hip arthroplasty, showing similar clinical and economic advantages over a 90-day episode of care. His research also incorporates computed tomography imaging costs, providing a comprehensive view of the economic trade-offs. Collectively, his work has helped establish the value proposition for robotic-assisted joint replacement, influencing surgical decision-making and reimbursement discussions. With over 78 citations across his top papers, Gregory is a key voice in the ongoing debate over technology adoption in orthopedics, offering evidence that robotic assistance can reduce readmissions, shorten hospital stays, and lower overall episode costs without compromising quality.
