cartilage begins to break down slowly as we age, potentially leading
to inflammation associated with osteoarthritis. This process can be

recurrent pressure on the cartilage and other parts of joints
improves tissue maintenance. Injection of hyaluronan solution into
the synovial cavity is a routine treatment for severe arthritis.
Dietary supplementation with chondroitin sulfate and glucosamine may
also slow progression of arthritis.
