Your doctor will likely apply a numbing agent before your Synvisc-One injection.

What happens after the injection?

It is recommended you avoid strenuous activities (for example, high-impact sports such as tennis or jogging) or prolonged weight-bearing activities for approximately 48 hours following the injection. You should consult your doctor regarding the appropriate time to resume these activities.

When will I start to feel pain relief?

Everyone responds differently, but in a medical study1 of 253 patients with knee osteoarthritis, many experienced pain relief starting one month after the injection of Synvisc-One.

How long will I experience knee pain relief?

Although all patients respond differently, your osteoarthritis knee pain relief can last up to six months.

Can I receive Synvisc-One treatment more than once?

Yes, Synvisc-One can be repeated safely. In a medical study involving 160 patients, 77 received a second injection of Synvisc-One. When your osteoarthritis knee pain returns, talk to your doctor to see if Synvisc-One is right for you.

Can both my knees be treated with Synvisc-One?

Yes. You can receive treatment in both knees at the same time or at different times. Ask your doctor what is best for you.

What is Synvisc-One made from?

The injection contains a gel-like mixture made from a substance called hyaluronan (pronounced hy-al-u-ROE-nan) that comes from chicken combs. Hyaluronan is a natural substance found in the body and is present in very high amounts in joints. The body’s own hyaluronan acts like a lubricant and a shock absorber in the joint and is needed for the joint to work properly.

How is Synvisc-One different from SYNVISC® (hylan G-F 20)?

Synvisc-One is the same formulation as SYNVISC. The only difference is that Synvisc-One is provided with one injection, compared to the three injections required for SYNVISC. Both treatments can provide up to six months of osteoarthritis knee pain relief.
