What Hospital for Special Surgery does
Hospital for Special Surgery (HSS) is a New York-based not-for-profit academic medical center founded in 1863 and recognized as the leading U.S. specialty hospital for musculoskeletal care, ranked #1 in orthopedics for 16 consecutive years and top-5 in rheumatology for 34 consecutive years by U.S. News & World Report. The institution employs 5,001–10,000 staff including 440+ physicians, 160 surgeons, 300+ full-time researchers, and 55 federally funded Principal Investigators, and it performs approximately 45,000 surgeries per year across its Manhattan flagship and Kellen Tower campus, regional physician offices and ambulatory surgery centers in New York, New Jersey, Connecticut, and Florida, and clinical alliances with Stamford Health, Jupiter Medical Center, NCH Naples, and UHealth/University of Miami.
HSS generates revenue primarily through patient care services — including orthopedic and rheumatology visits, imaging, inpatient and outpatient surgery, and rehabilitation — reimbursed by major commercial insurers (Aetna, BCBS, Cigna, EmblemHealth, UnitedHealthcare, Florida Blue), Medicare, Medicaid, and self-pay. Additional revenue streams include HSS Perform (a B2B employer channel offering prevention, triage, concierge, second opinion, and center-of-excellence services), HSS Foundation philanthropy (supporting $195M+ in capital expansion including Kellen Tower), the RightMove virtual musculoskeletal platform, the Alliance for Innovation in Movement (AIM) with Deerfield Management, and the new national ambulatory surgery center platform co-built with General Atlantic via the acquisition of Legent Health.
HSS operates a layered technology stack spanning Palantir Foundry/AIP for hospital operations, Ema AI agents for patient scheduling and triage, the HSS Digital Twin Platform for 3D surgical simulation, computer-assisted and robotic orthopedic surgery, and a national rehabilitation network of 1,500+ therapy providers. Research output exceeds 1,200 publications per year with 90+ patient registries and 100+ active clinical trials, supported by academic affiliation with Weill Cornell Medical College. Sports medicine partnerships with the UFC, New York Giants, Mets, Knicks, Red Bulls, Brooklyn Nets, USA Basketball, and NYRR, plus collaborations with Peloton and international patient services, extend brand reach across consumer, professional, and global audiences.
