Synvisc is a gel-based injection used to ease knee pain from osteoarthritis. It doesn’t mask the pain; it works mechanically, restoring the smooth movement the joint has lost through viscosupplementation.
Your knee normally relies on a thick natural fluid to absorb impact and let the bones glide past each other. Osteoarthritis breaks down that fluid, and without it, every movement can hurt.
That’s the gap Synvisc fills. It’s a thicker, longer-lasting form of hyaluronic acid, the same material your joint fluid is built from, designed to stay put and keep cushioning the knee for an extended period of time. A single Synvisc injection or short series can deliver relief lasting up to six months.
Because Synvisc is made from chicken combs, let your doctor know in advance if you have a poultry or egg allergy.
Synvisc injection is usually recommended when knee osteoarthritis is causing pain and simpler measures haven’t worked. If physical therapy, weight management, or over-the-counter pain relievers haven’t helped and the knee still hurts a lot, it may be the right next step.
It’s a good option for patients hoping to avoid or delay surgery, or who can’t rely on anti-inflammatory medications long-term. And since relief can last up to six months, it suits anyone who wants longer intervals between treatments. Synvisc works best for mild to moderate osteoarthritis.
A Synvisc appointment is short, usually under half an hour. Here’s what it looks like in general.
First, Dr. Tymouch examines the knee to see if the joint is holding extra fluid, which gets drawn off first, both to ease pressure and to give the Synvisc room to settle in properly.
Next comes preparation: the skin over the knee is carefully cleaned to maintain sterility, and a local numbing agent can be applied to make the Synvisc gel injection as comfortable as possible. Using a steady, guided technique, often with ultrasound guidance, Synvisc is delivered directly into the joint space.
The number of visits depends on the version used. Some patients get the full benefit from a single injection (also called Synvisc One injection), while the standard course runs three Synvisc injections spaced a week apart.
Once it’s done, you’re free to head home. Just keep the knee easy for the first couple of days – no running, heavy lifting, or long stretches on your feet while it settles.
When knee pain starts ruining your life, it’s time to deal with the root of it. At Painless Medical Practice in Chicago, IL, Dr. Tymouch considers the whole picture before making a recommendation, so you get the treatment that fits your situation.
Maybe Synvisc is the right choice, maybe it’s not. Either way, you’ll get a clear explanation and an honest recommendation, not a generic script.

Synvisc contains hylan G-F 20, a gel-like form of hyaluronic acid that helps cushion and lubricate the knee joint. It is designed to improve comfort and movement in people with knee osteoarthritis.
Synvisc works by supplementing the natural joint fluid that becomes depleted with osteoarthritis. By improving lubrication and shock absorption, a Synvisc injection can help reduce knee pain and improve mobility.
After a Synvisc injection, avoid strenuous activities, heavy lifting, running, and prolonged standing for about 48 hours. Most patients can return to normal light activities the same day.
The main difference is the number of injections. Standard Synvisc treatment is usually given as three injections over three weeks, while Synvisc-One delivers the full treatment in a single injection. Both are designed to provide long-lasting knee pain relief.
