Osteoarthritis is the most common form of arthritis. Progressive loss of cartilage at the edges of the joints and in the underlying bone causes osteoarthritis.

Arthritis literally means inflamed joint; however, there often is little inflammation in osteoarthritis. Osteoarthritis is a normal part of the aging process.

Symptoms of osteoarthritis include pain and swelling in joints where osteoarthritis is present.

The pain from Paget’s disease is sometimes mistaken as pain from osteoarthritis.
