Dr. Quanjun Cui is the G.J. Wang M.D. Professor of Orthopaedic Surgery and Vice Chair for Research, Department of Orthopaedic Surgery, University of Virginia School of Medicine. He is a board-certified orthopaedic surgeon and specialized in total hip and knee replacement. Dr Cui's research has been funded by NIH and DOD focusing on osteogenesis and arthritis. He has received numerous academic and professional accolades, including the Hip Society Otto Aufranc Award. He is a board member and reviewer for several prestigious journals. Dr. Cui is a fellow of the American Academy of Orthopaedic Surgeons (AAOS) and the American Orthopaedic Association (AOA). He served as President of the Virginia Orthopaedic Society in 2017 and President of the Association Research Circulation Osseous (ARCO) in 2020.

Dr. Kyung-Hoi (Kay) Koo is a musculoskeletal radiologist as well as an orthopaedic surgeon. During last 30 years, he has exclusively performed hip surgeries. He is interested in femoral head osteonecrosis and has actively participated in ARCO since 1994. He was President of ARCO from 2012 to 2015. Since 1997, he has used ceramic-on-ceramic bearings in total hip arthroplasty and has been instrumental in bringing ceramic-on-ceramic total hip arthroplasty. He has published over 300 peer-reviewed articles and more than 20 book chapters regarding femoral head osteonecrosis and total hip arthroplasty. He was an editor of the Bone and Joint Journal from 2015 to 2018 and currently, he is an editor of the Journal of Arthroplasty.
