The disabling disease wears away protective joint cartilage, which is the part of the joint that cushions the ends of bones.
Cartilage is a spongy substance that acts like a shock absorber where two bones meet.
It does not naturally grow back once it is damaged. Pain and loss of movement results when the cartilage is impaired, causing the bones to rub against each other. The degree of OA's disabling effects can range from mild to severe. Numerous factors can cause OA-from age to excess weight to accidents. Research has indicated that OA is not an inevitable part of aging, although genetics plays a role in the development of the disease.
