    About American Association of Orthopaedic Surgeons

    The American Association of Orthopaedic Surgeons channels most of its giving back into orthopaedic organizations and AAOS itself, with three very large general-support grants to the American Academy of Orthopaedic Surgeons in 2023, 2024, and 2025. Those awards alone account for the clearest signal in the recent record: this funder uses grantmaking to support the profession’s infrastructure as much as outside projects. Alongside that large institutional support, the foundation funds state and regional orthopaedic societies across the United States. Recent recipients include the Pennsylvania Orthopaedic Society, Minnesota Orthopaedic Society, New Jersey Orthopaedic Society, and Montana Orthopaedic Society, all listed for general support. The pattern points to a funder that supports professional associations, education, and organizational capacity rather than individuals. Its stated summary is serving the orthopaedic profession to provide the highest quality musculoskeletal health care, and the active grant programs align with that mission. The IDEA Grant Program supports education, community, and outreach initiatives, while Orthopaedic Research Excellence Awards support surgeon-led research and innovation in orthopaedic care. The recent grants list also shows repeated awards to several recipient organizations over multiple years, indicating sustained relationships rather than isolated transactions.

    What American Association of Orthopaedic Surgeons Funds

    One clear theme is professional association support. The foundation gave general support to the Pennsylvania Orthopaedic Society in both 2023 and 2024, and it also funded the New Jersey Orthopaedic Society and the Minnesota Orthopaedic Society with repeat awards. That suggests a steady relationship with member organizations that represent orthopaedic surgeons at the state level. Education and outreach appear in the active IDEA Grant Program, which is described as supporting education, community, and outreach initiatives, including orthopaedic diversity. That program is open to unsolicited applications in the United States. Research and innovation is another focus. The Orthopaedic Research Excellence Awards fund surgeon-led research and clinical innovation in orthopaedic care, with support available in the United States and internationally. The grant descriptions frame the foundation’s work as field-building: training, research, and professional capacity all sit alongside patient-facing priorities in the stated focus areas.

    How American Association of Orthopaedic Surgeons Gives

    Typical grants are modest relative to the organization’s large general-support awards: p25 is $7,500, median is $10,000, and p75 is $15,000. The recent record also includes three very large general-support grants to the American Academy of Orthopaedic Surgeons in consecutive years, showing a two-tier pattern of major institutional support and smaller association-level awards. The funder is a public charity, does not fund individuals, and does not make program-related investments. Repeat recipients appear across multiple years, especially among state orthopaedic societies and associations, which points to recurring grant relationships rather than one-off awards.

    Where American Association of Orthopaedic Surgeons Makes Grants

    Grantmaking is national, and every recent grant in the dataset went to a U.S. recipient. The top state by grant count is Maryland, even though the headquarters are in Rosemont, Illinois; 12% of grants went to recipients in Illinois. Recipient cities include Towson, St. Paul, Trenton, Lake Oswego, and Newark, showing a spread across regional orthopaedic organizations rather than a single metro area. Several awards also went to recipients in states outside the HQ state, including Montana, North Carolina, Georgia, and California.
