As Canada Research Chair in Joint Preservation Surgery, Dr. Olufemi Ayeni is advancing joint preservation care for patients of all ages. He and his research team are developing strategies to prevent joint injuries in children and youth, minimally invasive treatments to curb the development of joint disease in young adults, and new treatments for older patients with cartilage defects and early-onset osteoarthritis. They are also investigating new surgical techniques, adjuvant biologics, the etiology of hip impingement and its impact on the development of osteoarthritis. Their work will lead to better care for patients with hip and knee joint problems.
