Osteoarthritis is the most common form of arthritis and the leading cause of physical disability and activity limitations worldwide. Globally, arthritis is the most frequently diagnosed chronic disease, with osteoarthritis accounting for 40 to 60% of musculoskeletal conditions.

In Canada, over 15% of the population suffers from osteoarthritis, with more than two-thirds of those affected being 60 years and older. Women are more affected than men, with a higher incidence, prevalence, and severity. The prevalence of osteoarthritis increases with age, and its impact, combined with an aging population, makes it one of the major medical challenges of today and tomorrow.
