Osteoarthritis is a common chronic health condition. Among the estimated 27 million adults in the United States who had osteoarthritis in 2005, 33.6% were ages 65 and older (Lawrence, Felson, et al., 2008). One in 10 Canadians has osteoarthritis, and approximately 85% are ages 70 or older (Public Health Agency Canada).
