Sodium hyaluronate (also known as hyaluronic acid or hyaluronan) is a natural substance. It is present in the body wherever moisture is stored or lubrication between layers of tissue is required to eliminate friction.

Examples are inside the eye ball itself, the tear film, the joint cartilage, the synovial fluid in the joints, all the mucuous membranes of the body, but also the basic substance of the skin which consists of up to 55% sodium hyaluronate. 

Sodium hyaluronate takes on a variety of functions: 

  • Storage: it absorbs and stores moisture in enormous quantities

  • Lubrication

  • Transport medium for nutrients

  • Filter for inflammatory molecules.


It may help to visualise sodium hyaluronate as a dish of spaghetti (this is what the molecules look look like under an electronic microscope): a dense mesh that remains elastic and flexible in spite of its density and interwoven structure.

Sodium hyaluronate is an essential component of the synovial fluid. It enables the fluid to act as a lubricant, a shock absorber and a filter controlling the movement of cells and large molecules within the joint.

Sodium hyaluronate is injected into the space in the joint that contains synovial fluid and works by restoring the normal balance between the breakdown and production of sodium hyaluronate. This procedure is known as 'viscosupplementation.'


One such brand used in our clinic is OSTENIL® PLUS which can decrease pain and stiffness and improve the other symptoms of osteoarthritis.

The sodium hyaluronate in OSTENIL®PLUS is very pure and is manufactured using a process called fermentation. It contains no animal proteins, which means that it is very unlikely to cause an allergic reaction. OSTENIL® PLUS has been given to thousands of patients and has not been found to cause any serious side effects. The exact make-up of the sodium hyaluronate in OSTENIL®PLUS has been carefully chosen so that it is as effective as possible in treating osteoarthritis.

Only one injection per joint is required,  with pain relief often lasting for many months.
