Osteoarthritis is the most common form of arthritis and affects millions of Americans. Women are more likely to develop osteoarthritis, although the reason why is unknown. The most common reason for arthritis is genetics. Osteoarthritis is caused by damage or wearing down of the protective layer of cartilage in the joint. The cartilage helps the bones of the joint to glide or move effortlessly against each other. When osteoarthritis affects the joint, the result can be painful, debilitating friction from bone on bone contact.
Osteoarthritis can occur in any joint in the body, but is most common in the joints of the hands, knees, hips, and spine.
