About

Dr. Ali Bayan is a leading orthopaedic surgeon and researcher whose work is redefining surgical precision in total knee arthroplasty (TKA). His primary research focuses on optimizing alignment techniques—specifically comparing functional alignment (FA) against the traditional mechanical alignment (MA)—and evaluating the impact of robotic-arm assistance on patient outcomes. Dr. Bayan’s most influential contribution is his landmark randomized controlled trial (the John N. Insall Award paper, 2025, 36 citations), which provides compelling evidence that FA, when executed with robotic technology, can improve functional results and patient satisfaction over MA. He further demonstrated the superiority of robotic-arm-assisted TKA over imageless computer navigation, showing it yields better surgical accuracy and postoperative recovery (6 citations). Through his prospective randomized work (18 citations), Dr. Bayan has established a rigorous evidence base for adopting personalized, bone-resection-based balancing. His studies are highly cited for directly addressing the persistent problem of post-TKA dissatisfaction, offering surgeons a data-driven path to better outcomes. Dr. Bayan’s research is essential reading for any orthopaedic surgeon or student seeking to understand the future of technologically enhanced, patient-specific knee replacement.
