Synvisc-One
® (
Hylan G-F 20) is an
osteoarthritis treatment that is injected directly into the knee to cushion and lubricate the joint. Such treatments are known as viscosupplements. It is given as a single injection per knee and helps relieve pain for up to six months.
Synvisc-One is manufactured by Genzyme Biosurgery, a division of Genzyme Corporation.
How Does Synvisc-One Work?
Healthy joints contain synovial fluid.
This fluid works like a cushion and lubricant for the joint. In people with
osteoarthritis, the synovial fluid may break down, becoming thinner and less able to protect the joint.
Synvisc-One contains a mixture of hylan A and hylan B, two substances made from sodium hyaluronate, a natural product obtained from chicken combs. Hyaluronate is also found in the human body, especially within the joints and the synovial fluid. Injecting Synvisc-One into the joint helps provide the cushioning and lubrication lacking in the arthritic joint.
