Prevalence and Age
Osteoarthritis is one of the most common causes of pain for the adult population over 50 years of age. It is estimated that over twenty million Americans are afflicted with the condition, making it the most prevalent form of arthritis.
- Fewer than 10% of adults under thirty years of age are symptomatic
- Over 35% in the over sixty-five to seventy-five age bracket are symptomatic
- Almost all adults over 75 years of age display radiographic indications of osteoarthritis and joint degradation (although all are not symptomatic).
Gender
Osteoarthritis is equally prevalent in men and women in the first five decades. After age fifty, the incidence of osteoarthritis increases faster in women than men. Women are especially vulnerable to erosive osteoarthritis, osteoarthritis of the knees, and osteoarthritis of the spine.
Morbidity
Disease progression generally occurs over one or several decades.
