Stephan Maximillian Röhrl is a consultant at the Department of Orthopaedic Surgery at Oslo University Hospital Ullevål. Stephan is a specialist in general surgery and orthopaedic surgery and his clinical practice is focusing on reconstructive surgery of the hip and the knee. During his basic orthopaedic training in Umeå, Sweden, he started to work with radiostereometry and DEXA. After his PhD thesis on "wear and fixation of the acetabular component" in 2004 he was research fellow in 2005 at the University of Western Australia in Perth and came to Oslo in 2006. Since, he is leading CIRRO and focusing on research of joints with and without implants. In 2009 he became head of the Norwegian Society for Hip and Knee Surgery.
Stephan is a former German and European cup champion in Judo and has served as physician for the national judo team in Sweden and Norway.
