Chul‐Won Ha

About

Chul-Won Ha is a distinguished orthopedic researcher whose work has significantly advanced the field of total knee arthroplasty (TKA), with a particular focus on surgical precision, component alignment, and the integration of robotic technology into joint replacement procedures. His research addresses one of the most critical challenges in knee replacement surgery — achieving optimal mechanical alignment — recognizing that even minor deviations can lead to premature implant failure, abnormal wear, and patellofemoral complications. Ha's most impactful contribution, a 2012 cadaveric study garnering 92 citations, demonstrated through rigorous multiparameter quantitative three-dimensional CT assessment that robot-assisted TKA offers measurable advantages over conventional techniques in component alignment accuracy. Complementing this, his second highly cited work (44 citations) further validated that robotic assistance enhances precision even within the technically demanding context of minimally invasive surgery. Together, these studies helped establish an evidence base for adopting robotic platforms in knee arthroplasty at a time when the technology was still emerging. Ha's research has meaningfully shaped how surgeons approach implant positioning, influencing both clinical practice and the broader conversation around technology-assisted orthopedic surgery, making his work essential reading for researchers and clinicians exploring innovations in joint reconstruction.
