Osteoarthritis is the most common form of arthritis and is
associated with the aging process. Osteoarthritis is a chronic
disease causing the deterioration of the cartilage within a
joint.
For most people, the cause of osteoarthritis is unknown, but
metabolic, genetic, chemical, and mechanical factors play a role in
its development. Symptoms of osteoarthritis include loss of
flexibility, limited movement, and pain and swelling within the
joint. The condition results from injury to the cartilage, which
normally absorbs stress and covers the bones, so they can move
smoothly.
The cartilage of the affected joint is roughened and becomes
worn down. As the disease progresses, the cartilage becomes
completely worn down and the bone rubs on bone. Bony spurs usually
develop around the margins of the joint.
Part of the pain results from these bone spurs, which can
restrict the joint’s movement as well.
