American Academy of Orthopaedic Surgeons

American Academy of Orthopaedic Surgeons

The American Academy of Orthopaedic Surgeons was established in 1933 as a not-for-profit educational organization. It now operates as the world's largest medical association for musculoskeletal specialists, counting over 39,000 members globally. The governance rests with an elected leadership line: Wilford K. Gibson, MD serves as President for 2026, with Michael L. Parks, MD as First Vice President and Elizabeth G. Matzkin, MD as Second Vice President — a succession structure that makes Matzkin the slated President for 2028. AAOS manages a diversified investment pool deployed across venture capital, buyouts, distressed debt, secondaries, and special situations. The organization favors early-stage and expansion-stage allocations and also commits to fund-of-funds vehicles alongside direct co-investments. Industry-aligned partnerships anchor the strategy — the IDEA Grant Program, co-run with corporate partner Stryker, funds diversity initiatives, while the Orthopaedic Research and Education Foundation (OREF) serves as the primary conduit for research grants. AAOS also maintains formal collaborations with Zimmer Biomet, the American Association of Hip and Knee Surgeons (AAHKS), and the American Orthopaedic Society for Sports Medicine (AOSSM) to underwrite specialty education and advocacy. Geographically, the endowment funds initiatives spanning North America while serving a global membership base. The organization operates out of its commercial headquarters at 9400 West Higgins Road in Rosemont, Illinois, and controls the American Joint Replacement Registry (AJRR), a key data asset tracking hip and knee arthroplasty outcomes. Leadership includes non-surgeon public board member Timothy J. Constantine, a former healthcare executive at Highmark Inc. AAOS also holds a delegation in the American Medical Association (AMA) House of Delegates, providing policy influence. In 2026, the current leadership under President Gibson continued advancing industry-sponsored research partnerships and expansion of the registry program. AAOS is structurally distinct from a conventional foundation: it functions simultaneously as a membership organization, a clinical registry operator, and an allocator. Its deal flow ties directly to its corporate partner ecosystem — Stryker and Zimmer Biomet do not just sponsor events; they co-design grant programs that generate investable innovation. The leadership pipeline, where successive vice presidents ascend to the presidency, creates predictable governance, while the AJRR registry provides an information advantage in orthopaedic outcomes that peer societies lack.
