What is Viscosupplementation?

Viscosupplementation is the injection of a clear gel-like substance in the knee and can provide sustained* knee pain relief. A single injection of a viscosupplement like Cingal® or Monovisc®, can help alleviate pain caused by osteoarthritis of the knee while increasing the flexibility and mobility of your knee. In addition, the injection of a corticosteroid such as the one found in Cingal® can provide rapid knee pain relief.

Hyaluronic acid is a naturally occurring substance found in the synovial fluid of the knee joint. Viscosupplementation—or the injection of hyaluronic acid into the joint—is thought to lubricate the cartilage (much like oil lubricates an engine), thereby reducing friction and pain.

*Pain relief up to 6 months.

What is Cingal®?

A single injection that provides the quick pain relief of a corticosteroid with the long-term pain relief of a viscosupplement.

Cingal® is the only viscosupplement that combines a corticosteroid for fast pain relief with a viscosupplement, a clear gel-like substance containing hyaluronic acid, for sustained osteoarthritis knee pain relief.


How does Cingal® work?

Lubricant and anti-inflammatory properties working together:

Hyaluronic acid is thought to lubricate the cartilage (much as oil lubricates an engine), thereby reducing pain for long-term relief with a delayed onset.

Corticosteroid (or cortisone) has anti-inflammatory properties and may be used to relieve pain by reducing swelling in the joint for short-term rapid relief.


How long will a Cingal® injection last?

Pain relief with Cingal® generally occurs within 24 hours of administration and can last up to 26 weeks.

What is Monovisc®?

A hyaluronic acid injection that provides long-term relief from osteoarthritis knee pain.

Monovisc® is a viscosupplement that contains a gel-like substance manufactured from ultra-pure, non-avian hyaluronic acid that supplements the hyaluronic acid naturally found in the synovial fluid of a healthy knee.


How long will a Monovisc® injection last?

Monovisc® has been shown to provide effective osteoarthritis knee pain relief for up to six months.

Is Cingal® or Monovisc® right for me?

When to consider Cingal® or Monovisc® for osteoarthritis knee pain relief:

If oral painkillers and lifestyle changes such as exercising and losing weight are not providing you with adequate pain relief, Cingal® or Monovisc® may be a good option to relieve your osteoarthritis knee pain.
