Johan Witt is a Consultant Orthopaedic Surgeon at University College London Hospitals where he was appointed in 1995. He graduated from The Middlesex Hospital Medical School in London in 1983.
His orthopaedic training was in and around London with a year as a senior resident at the Massachusetts General Hospital in Boston, USA. He did fellowships in Sydney and Bern. In Bern he had the opportunity to spend time with Prof. Reinhold Ganz who is responsible for developing our understanding of the concepts of mechanical damage to the hip joint and the techniques to address this, in particular surgery for femoroacetabular impingement and hip dysplasia.
In 1995 he was appointed as a Consultant at The Middlesex Hospital and University College Hospital – now University College London Hospitals NHS Foundation Trust.
Early on he was involved in the surgical treatment of bone and soft tissue tumours. Increasingly his focus has been directed towards techniques of hip preservation surgery, and he has worked to promote the understanding of the conditions suitable for these interventions. He now sees a very large number of patients from all over the country referred to UCLH for the management of their hip problems and specialises purely on disorders of the hip.
His specialist interest is in young adult hip surgery, in particular periacetabular osteotomy (PAO) for hip dysplasia, arthroscopic and open surgery for femoroacetabular impingement (FAI). He has a large experience in total hip arthroplasty including in young adults and children. His research interests relate to outcome of minimally invasive periacetabular osteotomy, analysis of hip morphology using 3-D CT techniques with reference to FAI and hip dysplasia, longterm outcomes of ceramic hip bearings and minimally invasive total hip replacement using the direct anterior approach.
