Who develops osteoarthritis?
Osteoarthritis usually develops in people over 50 years of age and is more common in women than in men. It is commonly thought that osteoarthritis is an inevitable part of getting older, but this is not quite true. While in very old people the changes of osteoarthritis are visible on X-rays, they don’t always have related pain or problems with joint function.
Younger people can also be affected by osteoarthritis, often as a result of an injury or another joint condition.
Osteoarthritis breaks down the cartilage in your joints. Cartilage is the slippery tissue that covers the ends of bones in a joint. Healthy cartilage absorbs the shock of movement. When you lose cartilage, your bones rub together. Over time, this rubbing can permanently damage the joint.
