It develops when the cartilage -- the smooth covering that protects the bones in the joint -- breaks down. The surface of the bones becomes damaged, causing pain, swelling, stiffness, and disability.
In people with osteoarthritis, a critical substance in synovial fluid known as hyaluronic acid breaks down. They have a lower-than-normal concentration of hyaluronic acid in their joints. Loss of hyaluronic acid appears to contribute to joint pain and stiffness. Although there is no cure for osteoarthritis, there are many treatment options available to help people manage pain and stay active.
People with osteoarthritis have a lower-than-normal concentration of hyaluronic acid in their joints. The theory is that adding hyaluronic acid to the arthritic joint will facilitate movement and reduce pain.
