Sodium Hyaluronate is a chemical used in the treatment of arthritis and osteoporosis (you may have seen advertisements for various brands of the drug on television). The substance is injected into the knee and essentially acts as a lubricant, shock absorber and pain reliever while also stimulating the natural production of synovial fluid. Essentially it acts as a replacement for the fluid that is naturally occurring in the joint. Therapies like this are known as viscosupplementation. It is generally used as a last resort before surgery or joint replacement should analgesics like acetaminophen fail.
It is important that you tell your doctor if you have any allergies to bird products (such as feathers, eggs or poultry), as the substance is obtained from the crown of the rooster. You should also not receive injections if you have any infections in the area where it is to be administered. Only your doctor should deliver Hyaluronate treatment and the drug has yet to be tested on joints other than the knee. You should also be aware that all drugs have side-effects and that the success of any therapy varies among individuals.
