What is osteoarthritis (OA)?
OA is a common health condition. It affects over 27 million people in the United
States. OA involves the breakdown of joint cartilage. Cartilage is a firm, rubbery
material. It protects bones at a joint. If you have OA, things like walking or even
standing may be difficult.
How do you get OA?
In healthy joints, cartilage cushions your bones. It protects them when you move.
But in some people, cartilage breaks down. Over time, its smooth surface gets rough.
Cartilage can wear down all the way. When that happens, your bones may rub against
each other. That’s what causes joint pain.
Instead of living with the pain, talk to your doctor. Find out about the
treatment options available.
