The Osteoarthritis Initiative (OAI) is a multi-center, ten-year observational study of men and women to improve the understanding of prevention and treatment of knee osteoarthritis, one of the most common causes of disability in adults. The OAI is a permanent archive of the clinical data, patient reported outcomes, biospecimen analyses, quantitative image analyses, radiographs (X-Rays) and magnetic resonance images (MRIs) acquired during this study. While querying and browsing data is publicly available, all subject-level data is available behind a login.
