About

Jae-Hyeok Cheon is an emerging leader in orthopaedic surgery, specializing in total knee arthroplasty (TKA) and the precision-driven evolution of robotic-assisted joint replacement. His research centers on optimizing surgical alignment techniques—specifically comparing functional alignment (FA) and mechanical alignment (MA)—to improve patient outcomes and implant longevity. Cheon’s major contributions include demonstrating how a tibia-first, restricted functional alignment technique in robotic-arm-assisted TKA enhances the predictability of gap dimensions and achieves more consistent soft-tissue balance, as shown in his 2024 study (13 citations). He further advanced the field by analyzing weight-bearing knee positions and parallelism to the ground using innovative hip-to-calcaneus radiographs, revealing superior functional outcomes for robotic-assisted FA-TKA over conventional MA-TKA (2025, 6 citations). With a growing citation impact, Cheon’s work is shaping the next generation of personalized, data-driven arthroplasty. His achievements underscore a commitment to merging biomechanical principles with cutting-edge robotics, making him a key voice in the transition toward more reproducible, patient-specific knee replacement surgery.
