Our Contributors
All OrthoInfo articles are written by orthopaedic surgeons who are experts in their field, then peer-reviewed by physician members of the OrthoInfo Editorial Board.
In order to promote transparency and confidence in the educational materials of the American Academy of Orthopaedic Surgeons (AAOS), AAOS maintains an up-to-date record of the disclosures of many business relationships of OrthoInfo contributors. AAOS makes this information available to the public to allow people to assess whether the information presented is as unbiased as possible. AAOS does not view the existence of these interests or relationships as decreasing the value of the contribution.
Readers will find contributors and peer reviewers listed at the end of most OrthoInfo articles. Their names will link to their disclosure information. Learn more about the AAOS Orthopaedic Disclosure Policy.
The full list of contributors below includes OrthoInfo authors, as well as subject-matter experts who have participated in the development of our content over the years.
