About

Sophie Putman is a rising orthopaedic researcher whose work focuses on advancing total knee arthroplasty (TKA) through precision biomechanics and robotic assistance. Her primary research areas include ligament balance, joint line obliquity, and the role of the posterior cruciate ligament (PCL) in knee replacement outcomes. Her most cited paper, “Variation in knee balance as a function of hip-knee-ankle angle and joint line obliquity in robotic assisted total knee arthroplasty” (2022, 19 citations), provides critical insights into how alignment parameters influence soft tissue tension during surgery. She further demonstrated the accuracy and functional benefits of robotic systems in a comparative study of a single TKA design (2025, 4 citations). A notable recent contribution is her investigation into PCL resection, which found that removal increases lateral and medial flexion laxity (2025, 2 citations)—a finding with direct implications for surgical decision-making. Though early in her career, Putman’s work is already shaping how surgeons approach ligament management and robotic workflows, offering data-driven guidance for improving patient outcomes in knee arthroplasty.
