Orthopaedic Research Society 2021 Annual Meeting

The Orthopaedic Research Society (ORS) 2021 Annual Meeting will include presentations from Columbia Orthopedics. ORS is an international hub for biologists, engineers, clinicians, surgeon-scientists, orthopaedic surgeons, and veterinarians within the field of musculoskeletal science and orthopaedic care. The virtual meeting will take place on February 12 – 16.

See below for the syllabus of podium and poster presentations being presented by Columbia Orthopedics faculty, residents, and researchers:
