Personal profile
Brief presentation
Due to a former career as active sportsman and the experience of tear of the anterior cruciate ligament in both knees Kristoffer was focused to become a sports surgeon from the start of his career.
Kristoffer completed his medical studies in 2006, finished his surgical training in 2014 and passed the exam as a Certified Sports physician in 2015. Since, he subspecialized in arthroscopic surgery and sports traumatology through Fellowships at Zealand University hospital Koge, Institute for Sports Medicine Copenhagen (ISMC) at Copenhagen University Hospital Bispebjerg, and OthoSport Victoria in Melbourne, Australia, where he was trained in advanced knee surgery by Professor Julian Feller. From 2007 to 2013 he worked as consultant and associate professor at Sports Orthopedic research center – Copenhagen, SORC-C, where he was trained by Professor Per Hölmic.
Parallel to his training he completed a PhD study entitled ‘Achilles tendon rupture; Assessment of non-operative treatment’ for which he was awarded the price ‘Best PhD of the Year 2014’ by the Danish Orthopedic Society.
Kristoffer is an active researcher leading ongoing projects concerning shoulders, knees, and Achilles tendon injuries.
