What is Synvisc-One?

Synvisc-One is an injection that supplements the fluid in your knee to help lubricate and cushion the joint, and can provide up to six months of osteoarthritis knee pain relief.

When should I consider Synvisc-One?

Synvisc-One is for people with knee osteoarthritis who have not received enough pain relief from diet, exercise and over-the-counter pain medication. If you’ve tried these options and are still feeling knee pain, tell your doctor and ask if Synvisc-One could help.

How is Synvisc-One given?

Synvisc-One is a single-dose treatment that is injected directly into your knee by a doctor.

What are the side effects of Synvisc-One?

The most common side effects are pain, swelling, heat, redness and/or fluid build-up around the knee. In a medical study less than 6% of patients experienced these side effects, which were generally mild and did not last long.

What is the procedure like?

The injection takes a few minutes and can be done in your doctor’s office.

Will the injection hurt?

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.


Synvisc-One® (hylan G-F 20) is indicated for the treatment of pain in osteoarthritis (OA) of the knee in patients who have failed to respond adequately to conservative non-pharmacologic therapy and simple analgesics, e.g., acetaminophen.

Important Safety Information for Synvisc-One

Before trying Synvisc-One, tell your doctor if you have had an allergic reaction, such as swelling of the face, tongue or throat, respiratory difficulty, rash, itching or hives to SYNVISC or any hyaluronan-based products. Synvisc-One should not be used in patients with an infected knee joint, skin disease or infection around the area where the injection will be given, or patients with circulatory problems in the legs.

Synvisc-One is only for injection into the knee, performed by a doctor or other qualified health care professional. Synvisc-One has not been tested to show pain relief in joints other than the knee. Tell your doctor if you are allergic to products from birds – such as feathers, eggs or poultry – or if your leg is swollen or infected.

Synvisc-One has not been tested in children (≤21years old), pregnant women or women who are nursing. You should tell your doctor if you think you are pregnant or if you are nursing a child.

Talk to your doctor before resuming strenuous weight-bearing activities after treatment.

The side effects sometimes seen after Synvisc-One include (<2% each): pain, swelling, heat, redness, and/or fluid build-up in or around the knee. Tell your doctor if you experience any side effects after treatment with Synvisc-One.
