What Pennsylvania Orthopaedic Society does
Mission
The Pennsylvania Orthopaedic Society works to enhance our members' ability to provide the highest quality musculoskeletal care.
As stated on its FY2024 Form 990.
Programs
Pennsylvania Orthopaedic Society hosts scientific meetings annually. These meetings provide a forum for discussion/teaching of the management of all musculoskeletal conditions.
Pennsylvania Orthopaedic Society engages in educational and lobbying efforts to promote the practice of orthopaedics in relationship to medical liability reform, workers' compensation, and phase-out of the Mcare Fund along with preservation of physician ownership of ancillary services. Additional efforts include working to improve contractual relationships between physcians and health insurers.
The 2 programs described on its FY2024 Form 990, listed largest first by expense.
The organization over time
Each line starts at 100 in 2017, so what you read is the shape rather than the size: 150 means half as much again as 2017, 50 means half. The number beside each label in the key is where it ended.
Balance sheet
Total assets and total liabilities at each year end, in dollars. The largest one-year move in total assets was 2022 to 2023, from $718k to $1.3M (+82%).
How it's funded, over time
Each bar is one year's revenue split into where it came from, and every bar is the same height — these are shares, not amounts, so a year that raised twice as much looks the same size. Hover a bar for the split.
Government-grant reliance: 2019 31% · 2020 42% · 2021 37%. Grants only. Government contracts and fees sit inside program revenue.
Surplus & reserves
Operating surplus or deficit each year, and months of liquidity in hand. 4 of the last 8 reported years ran a deficit.

Leadership and staff
The officers, directors, trustees and key employees listed on each return. Joined and no longer listed compare each filing with the year before, matching people by surname and first initial; a year after a gap, or a roster under three people, has no comparison.

2017 → 2023: the base held at 1 funder, grant income rose $5k → $15k.
From the IRS filings of Pennsylvania Orthopaedic Society’s funders (the co-funder graph). Association, not causation. Trends are read to FY2023, the last fiscal year that has finished arriving. FY2024–FY2026 are still being filed and are shown unshaded; they do not move any figure on this page.
How concentrated its funding is
Pennsylvania Orthopaedic Society leans on a few funders — its largest provides 91% of grant income and the top three 100%; half comes from just 1 funder.
the vertical line marks half of all grant income — 1 funder to its left
100% of the income these shares are computed over arrives through pass-through sponsors or from payers whose filings do not say what kind of payment it is. Concentration is still measured over all of it, because the money is real; what it does not support is a claim about how many institutions have chosen to fund Pennsylvania Orthopaedic Society.
Largest funder’s share by year: 2017 100% · 2018 60% · 2019 100% · 2021 100% · 2022 100% · 2023 100% — broadly stable.
