biologists, pathologists, radiologists, physioterapists and orthopaedic surgeons. In 1997, Engebretsens group did the first knee joint chondrocyte transplantation in Norway. Since then, the group has had major emphasize on translational research. The group works very closely with the Stem Cell group led by dr Brinchmann and has optimized chondrocyte and stemcell cultivation while at the same time developing surgical techniques for implantation In addition to being the current Past President of The European Society of Sports Traumatology and Arthroscopy (ESSKA), Dr Engebretsen has been the President of the Norwegian Sports Medicine Society, the Scandinavian Foundation of Sports Medicine and ESSKA.
