Can you tell me more about hyaluronic acid, for treating arthritis and rebuilding cartilage?

See details: It does not rebuild cartilage but it can privide temporary relief in some patients with osteoarthritis of the knee. The benefit usually last about 6 months and the injections can be repeated as long as they help. The exact mechanism is unknown but the commonly held explanation that it works as a lubricant is not likely the correct answer.
