Publish date:: April 4, 2016

More than half of all persons with symptomatic knee osteoarthritis (OA) are younger than 65 years of age, according to analysis of data from the National Health Interview Survey 2007-2008. Researchers found:

• About 14 million people had symptomatic knee OA, with advanced OA comprising more than half of those cases.

• That figure includes more than 3 million African American, Hispanic, and other racial/ethnic minorities.

• Adults aged ≤45 years accounted for nearly 2 million cases of symptomatic knee OA.

• Adults aged 45 to 65 years accounted for 6 million more cases of symptomatic knee OA.
