About Wayne

Research Interests: Equine orthopaedic surgery, joint disease research as well as osteoarthritis therapy (including gene therapy and stem cell therapies), articular cartilage repair, and early diagnosis in osteoarthritis and pre-fracture disease using imaging and fluid biomarkers. Dr. McIlwraith, a University Distinguished Professor, has made significant strides in advancing the Orthopaedic Research Center Laboratory's reputation through publications, scientific presentations, and fundraising. He is a Past-President of the American College of Veterinary Surgeons and the American Association of Equine Practitioners, and a recognized leader in the field of equine orthopaedic research and surgery. He consults worldwide as a specialist equine surgeon and has received media attention for his contributions to joint research. Dr. McIlwraith is the co-author of five textbooks, over 400 textbook chapters and refereed publications, and has given 600 presentations and workshops.
