Synvisc-One (hylan G-F 20) is an elastoviscous high molecular weight fluid containing hylan A and hylan B polymers produced from chicken combs. Hylans are derivatives of hyaluronan (sodium hyaluronate). Hylan G-F 20 is unique in that the hyaluronan is chemically cross linked. Hyaluronan is a long-chain polymer containing repeating disaccharide units of Na-glucuronate-N-acetylglucosamine.

Synvisc-One is indicated for the treatment of pain in osteoarthritis (OA) of the knee in patients who have failed to respond adequately to conservative nonpharmacologic therapy and simple analgesics, e.g., acetaminophen.

Who is a candidate for Synvisc-One
Patients with knee osteoarthritis, who have tried diet, exercise and over-the-counter pain medication but still have pain, should talk to their doctor to see if Synvisc-One is right for them.

How Synvisc-One is administered
Synvisc-One is a single injection. It’s a simple, in-office procedure that only takes a few minutes.

What you can expect following a Synvisc-One knee injection
Synvisc-One can provide up to six months of osteoarthritis knee pain relief. Everyone responds differently, but in a medical study* patients experienced relief starting one month after the injection.

After the injection, you can resume normal day-to-day activities, but you should avoid any strenuous activities for about 48 hours.
