Global Epidemic

Osteoarthritis (OA) is one of the leading causes of severe long-term pain and disability, with over 100 million individuals suffering from this debilitating disease world-wide.

In addition to the functional disability, reduced quality of life, and loss of income for the patient, OA is a major burden on health and social care systems.
