About

Jong-Ha Chung is a biomedical robotics researcher whose work has centered on the development of surgical robotic systems for orthopedic procedures, particularly total hip arthroplasty (THA). He is best known for conceiving and advancing ARTHROBOT, a pioneering femur-mountable surgical robot designed to improve the precision of femoral stem implantation during hip replacement surgery. Chung's most significant contribution is the development of an innovative gauge-based registration method, which eliminates the reliance on preoperative CT scan data by using a reamer-shaped instrument inserted directly into the femoral medulla to capture positional information — a practical and cost-effective alternative to conventional imaging-dependent approaches. His research has systematically progressed from conceptual design and mechanism development to rigorous experimental validation, including trials with sawbones, pig femurs, and cadaveric specimens, demonstrating a commitment to translational relevance. ARTHROBOT's 4-DOF motion capabilities and bone-mounting design represent meaningful advances in minimizing surgical variability and improving implant accuracy. Across his key publications, Chung has accumulated roughly 105 citations, reflecting a focused but impactful body of work that has informed subsequent research in orthopedic surgical robotics and image-free registration techniques.
