As of January 2019, all OAI data, documentation and images are now hosted by NIH and available here

The OAI is a nationwide research study, sponsored by the National Institutes of Health (part of the Department of Health & Human Services), that will help us better understand how to prevent and treat knee osteoarthritis, one of the most common causes of disability in adults.
