What is hylan G-F 20 (Synvisc, Synvisc One)?
Hylan G-F 20 (Synvisc, Synvisc One) is an injectable fluid that is used to treat osteoarthritis (OA) of the knee. Osteoarthritis is a type of arthritis in which the joints of the body degenerate and become painful and stiff. Osteoarthritis is the most common form of arthritis. Almost 10 million Americans suffer from the disease. Most people with OA are those 45 years old, and women. More women have OA than men.
How does Synvisc work?
Joints contain a fluid, called synovial fluid, which acts as a lubricant and shock absorber. Patients with osteoarthritis have synovial fluid that is thinner than normal, and, therefore, it is less effective as a lubricant and shock-absorber. Synvisc is an elastic fluid that is made from a substance called hyaluronan, that is found in normal joint fluid. Hyaluronan is the key substance in joint fluid that provides the shock-absorbing quality to the fluid, and it is essential for the proper functioning of joints. When Synvisc is injected into the knee of a patient with osteoarthritis, the drug helps to restore the shock-absorbing effect of the fluid within the knee. This can reduce pain, resulting in a more active lifestyle.
