Data on the prevalence of OA are based primarily
on X-ray surveys and self-report questionnaires.
It’s estimated that 27 million people over the age of 25 in the United States have OA.
The Centers for Disease Control and Prevention predicted in 2006 that 67
million people, or one quarter of the U.S. adult population, will be diagnosed with some form of arthritis
by 2030.
Although uncommon under the age of 40,
the prevalence of radiographic OA in all joints in-creases with age.
People including the aging baby
boom population are living longer now, so the burden of OA is rising sharply
