Eivind Inderhaug, MD, MPH, PhD
Consultant Orthopaedic Surgeon, Haraldsplass Deaconess Hospital
Bergen, Norway

Eivind Inderhaug is a Consultant Orthopaedic surgeon specializing in knee surgery and sports medicine at Haraldsplass Deaconess Hospital, Bergen, Norway. Inderhaug graduated from University of Oslo, and did his post-graduate training in Bergen. In addition to his medical degree, Inderhaug has served as an officer in the Norwegian Armed Forces and has a Master in Health Economics, Policy and Management from University of Oslo. A special interest is in cost-efficiency analyses and evaluation of health-care programs.

Inderhaug defended his PhD-thesis “Changing paradigms of ACL surgery” in 2015 and later undertook a post-doc/research fellowship at Imperial College London under the supervision of Andrew Amis. Research interests include clinical studies on knee and shoulder surgery and has lately expanded to include anatomical and biomechanical perspectives.

Directing a group of researchers from Orthopaedics, Radiology, Physiotherapy and Engineering, Inderhaug is supervising a range of Master and PhD students. Inderhaug is a Member of NOF, AAOS, ESSKA and ACL study Group. He has received numerous prices and grants for past and ongoing research projects. With an extensive list of publications and book chapters, he regularly attends international conferences and meetings as an invited speaker and instructor.
