True or false: Osteoarthritis is caused by your joints wearing out with old age.

False

Osteoarthritis is a complicated disease that no one fully understands, but it is not due to aging. In osteoarthritis, the cartilage lining the surface of your joint gets rough and cracked, and your bones grow to try to repair the damage.
