Inderhaug’s research focuses primarily on knee surgery and sports traumatology, with particular emphasis on ACL injuries, outcomes following surgical treatment, and how treatment choices influence patients’ function over time.

He leads the Norwegian Knee Ligament Register, a national quality registry collecting data on treatment and outcomes following ligament surgery in Norway. The registry is used to evaluate treatment methods, identify factors influencing surgical outcomes, and contribute to improved patient care.

He has published more than 100 scientific articles in international journals within orthopaedics, sports traumatology, and knee surgery. He is also involved in international research collaborations and actively contributes to advancing knowledge in the treatment of knee injuries.

Eivind Inderhaug actively disseminates knowledge within knee surgery, sports traumatology, and the treatment of knee injuries to healthcare professionals, academic communities, and patients. He regularly lectures and teaches courses nationally and internationally, and provides education for orthopaedic surgeons on the management of ACL injuries, meniscal injuries, and other complex knee injuries.

Through his role as leader of the Norwegian Knee Ligament Register, he contributes to the dissemination of knowledge on outcomes following knee surgery and the importance of evidence-based treatment. He is also committed to making medical knowledge accessible to patients and the general public, enabling people with knee injuries to make informed decisions about their treatment.

He has extensive teaching experience in orthopaedics, knee surgery, and clinical examination techniques. He teaches medical students at the Faculty of Medicine, University of Bergen, throughout the medical curriculum, including clinical propaedeutics and clinical examination techniques during several semesters (2nd, 5th, 6th, and 12th semesters).

He also contributes actively to postgraduate and continuing education for healthcare professionals, teaching orthopaedic trainees, general practitioners, physiotherapists, and other clinicians. His teaching activities include the National Arthroscopy Course for orthopaedic trainees, the National Orthopaedics Course for Physiotherapists, and teaching at Western Norway University of Applied Sciences, including physiotherapy and master’s students.

Through teaching and supervision, he works to promote evidence-based practice and contribute to the education and development of future healthcare professionals in the diagnosis, treatment, and rehabilitation of patients with musculoskeletal conditions.
