About

Franck Lacaze is a leading orthopedic researcher whose work is redefining total knee arthroplasty (TKA) through patient-specific surgical alignment. His primary research focus is on kinematic alignment strategies, particularly the development and validation of inverse kinematic alignment (iKA)—a novel, patient-specific concept that aims to restore native knee kinematics rather than enforcing a neutral mechanical axis. Lacaze’s most-cited paper, "Inverse Kinematic Alignment for Total Knee Arthroplasty" (2022, 79 citations), provides a foundational framework for this approach, detailing its theoretical benefits and potential advantages over traditional alignment methods. By systematically comparing different alignment concepts, his work has clarified how iKA might improve clinical outcomes by respecting individual anatomical variation. This contribution has positioned Lacaze as a key voice in the ongoing shift toward more personalized arthroplasty techniques, influencing both surgical practice and implant design. His research is essential reading for surgeons and engineers seeking to optimize TKA outcomes through biomechanically sound, patient-tailored alignment.
