Osteoarthritis affects 27 million Americans and is the leading disability in older adults. Athough age is a risk factor, the diagnosis is not inevitable due to age. The disease is caused by a breakdown/lost of the cartilage that holds joints together. If there is too little cartilage it will cause bones to rub together, causing pain and stiffness.
