What Causes Osteoarthritis?
Osteoarthritis occurs when the cartilage that cushions the ends of bones in your joints gradually deteriorates. Cartilage is a firm, slippery tissue that enables nearly frictionless joint motion. Eventually, if the cartilage wears down completely, bone will rub on bone. Primary osteoarthritis is caused by the breakdown of this cartilage. It can happen in any joint but usually affects your fingers, thumbs, spine, hips, knees, or big toes. Osteoarthritis is more common in older people.
