After arthroscopic surgery, VISCOSEAL® acts as a temporary
substitute for the lost synovial fluid and is added directly into
the joint. Any saline still remaining in the joint will be displaced
and the cartilage returns to its natural position.

The active ingredient in VISCOSEAL® is called sodium hyaluronate
(also known as hyaluronic acid or hyaluronan).

Sodium hyaluronate is a naturally occurring substance that is present in the body wherever moisture is stored or lubrication between layers of tissue is required to eliminate friction. Examples are the tear film, the vitreous body of the eye itself, the skin, all the mucuous membranes of the body, cartilage, and particularly the synovial fluid in the joints. More about sodium hyaluronate...>>>

The sodium hyaluronate in VISCOSEAL® is concentrated to make VISCOSEAL® very similar to naturally occurring synovial fluid. Your cartilage is immediately protected and nourished again, and the joint functions without friction.


  • is an isotonic solution of sodium hyaluronate
  • has a physiological pH

  • has a 0.5% concentration of sodium hyaluronate, which is similar to
    that in synovial fluid.

VISCOSEAL® acts as a temporary substitute for the lost
synovial fluid, thus accelerating recovery after arthroscopy

How does VISCOSEAL® work?


  • restores the lubricating, shock-absorbing and filtering properties of the synovial fluid

  • re-establishes the protective coating of the surface of the cartilage and the synovial membrane

  • reduces inflammation

  • alleviates pain

  • enhances the production of endogenous sodium hyaluronate (produced naturally by the body)


Advantages for You

Studies done by renowned surgeons have shown excellent results. VISCOSEAL® eliminates many complaints (impairments) after arthroscopy, some of which could be: swelling, reduced mobility, and joint pain both when at rest and when load bearing. Long-term studies have even proved a significant advantage after 2 years for those patients who received VISCOSEAL®. So the beneficial effects of VISCOSEAL® are not only short-term, but long-lasting.*
