About

Rex Wang-Fung Mak is a rising orthopedic surgeon-scientist whose research focuses on advancing total knee arthroplasty (TKA) through precision alignment technologies and implant design. His work centers on three key areas: the clinical impact of coronal plane alignment in knee replacement, the comparative accuracy of robotic-assisted versus navigation-guided surgery, and the development of open-platform robotic systems that offer greater surgical flexibility. In his most cited paper (7 citations, 2025), Mak challenges conventional wisdom by demonstrating that coronal plane alignment changes do not significantly affect outcomes for TKA implants designed with a 3-degree varus joint line—a finding that could reshape surgical planning. His comparative study (3 citations, 2025) shows that handheld imageless robotic TKA outperforms accelerometer-based navigation in both accuracy and early clinical outcomes, marking an important step toward more accessible robotic technologies. Additionally, his multicenter trial (1 citation, 2025) on open-platform image-based robotic systems highlights his commitment to expanding surgical options beyond proprietary implants. With a growing citation footprint and a focus on practical, evidence-based improvements to TKA, Mak is establishing himself as a thoughtful contributor to the future of joint replacement surgery.
