The Osteoarthritis Initiative (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.

Osteoarthritis (OA) is the most common form of arthritis and the major cause of activity limitation and physical disability in older people. Today, 35 million people (13 percent of the U.S. population) are 65 and older, and more than half of them have radiological evidence of osteoarthritis in at least one joint. By 2030, 20 percent of Americans (about 70 million people) will have passed their 65th birthday and will be at risk for OA.

The Osteoarthritis Initiative (OAI) is a multi-center, longitudinal, prospective observational study of knee osteoarthritis (OA). The overall aim of the OAI is to develop a public domain research resource to facilitate the scientific evaluation of biomarkers for osteoarthritis as potential surrogate endpoints for disease onset and progression.

Qmetrics gratefully utilizes the vast image and clinical data collected by the OAI to refine image analysis technology and to contribute to a better understanding of the causes and effects of OA. Qmetrics’ scientific and medical team have used OAI data for abstracts and posters at various scientific meetings, including this poster at the 2016 OARSI World Congress, “Detecting subjects at risk of radiological progression: Data from the OAI.”
