Professor Peter Chiu was the Chief of Division of Joint Replacement Surgery from 1997 to 2017. Professor Chiu graduated from the Faculty of Medicine at The University of Hong Kong in 1987. After the internship year, he worked in the Department of Orthopaedics and Traumatology at Queen Mary Hospital as a medical officer in 1988. He joined the University and became a lecturer in 1991, senior lecturer in 1996, subsequently becoming professor in 2006.

Professor Chiu’s research work is related to joint diseases. An important part of his research is about osteoarthritis of the knee. His studies show that Asian knees are different from Western knees, the findings have great impacts on the surgical management of Asian patients with advanced knee joint diseases. Professor Chiu also studies the role of subchondral bone in the pathogenesis of osteoarthritis, the application of cartilage repair for earlier diseases, the genetics and epidemiology of osteoarthritis and non-surgical management of knee osteoarthritis. His research works in the hip joint include the pathogenesis and management of avascular necrosis of the femoral head as well as hip replacements for patients suffering from ankylosing spondylitis. His outstanding research in the hip joint and his contributions to hip surgery culminated to his induction into the International Hip Society in 2008.

Professor Chiu is very active in educating young orthopaedic surgeons in the arts and science of joint replacement surgery. He trained over 2,000 surgeons from every part of China in the past 20 years. He has been invited to lecture in different countries for more than 100 times. He has published more than 250 book chapters and peer-reviewed articles.

He has also been the office bearer of many professional bodies, including the founding President of Adult Joint Reconstruction chapter of Hong Kong Orthopaedic Association. He was the President of the Hong Kong college of Orthopaedic Surgeons from 2014 to 2016.

His current clinical focus is on the use of robotic arm assisted technology to perform cementless total knee arthroplasty in the younger and more active patients. He trains surgeons from Hong Kong and China in performing this procedure.
