Education & Research

Hoag Orthopedics is a 501c3 non-profit founded by Hoag Orthopedic Institute physicians. The non-profit exists to foster education, research and community outreach in orthopedic medicine.


We are actively involved in medical research and support multiple projects teamed with industry leaders and innovators to develop new orthopaedic treatment modalities based on scientific methodology. This will lead to improved patient outcomes and world-class orthopedic care.


In addition to research, education will be a focus to support fellowship training. Research and resident education is equally important to train the next generation of skilled surgeons. Financial support for this endeavor is achieved only through generous donations to the institute.
