The hyaluronan is derived from bacterial cells and is cross-linked with a proprietary solution.

In osteoarthritis, there are abnormalities with the synovial fluid as well.

Synovial fluid lubricates the joint normally, allowing for friction-free movement.

Other Viscosupplements

The first viscosupplement was approved in 1997.

This conclusion was based on a meta-analysis of 89 randomized trials involving more than 12,000 knee osteoarthritis patients.

It is most effective if the arthritis is in its early stages (mild to moderate).

Some patients may feel pain at the injection site, and occasionally the injections result in increased swelling.

It may take several weeks to notice an improvement after viscosupplementation.

Not all patients will have relief of pain.

If the injections are effective they may be repeated after a period of time, usually 6 months.

The long-term effectiveness of viscosupplementation is not yet known and research continues in this area."
