Hyalgan is a hyaluronic acid joint injection used to treat knee pain in osteoarthritis. It works by replenishing the joint’s natural shock absorber – the thick fluid that keeps bones from making direct contact during movement. It belongs to the category of viscosupplementation, which restores cushioning inside the knee joint.
During osteoarthritis, the fluid thins out and loses its ability to protect the joint. Hyalgan goes in and fills that gap. It coats the joint, reduces the friction that causes pain, and carries mild anti-inflammatory effects that help calm irritated tissue.
It won’t undo cartilage damage entirely, but it gives the joint what it needs to work with less pain. Most patients receive five weekly Hyalgan injections, with effects that can last for months.
Hyalgan is usually considered for knee pain treatment when pain relievers, physical therapy, and lifestyle changes haven’t worked. It’s also a good fit for patients who want to avoid or delay surgery, or those who can’t take anti-inflammatory medications long-term.
Dr. Tymouch will recommend it when osteoarthritis is confirmed as the source of pain. It tends to work best in mild-to-moderate cases.
There is no reason to just live with knee pain and osteoarthritis, trying to walk it off and pretending everything is fine. There are numerous treatments available, and pain relief is possible.

Hyalgan is a hyaluronic acid joint injection used to treat knee pain caused by osteoarthritis. It replenishes the natural shock-absorbing fluid in the knee joint, reducing pain and improving mobility. By restoring lubrication, Hyalgan helps reduce friction and alleviates symptoms of osteoarthritis.
Hyalgan is primarily used to treat knee pain caused by osteoarthritis, especially when other treatments like pain relievers or physical therapy have not provided sufficient relief. It is an option for patients looking to avoid or delay knee surgery.
The effects of Hyalgan injections typically last for several months, with relief lasting up to 6 months or longer in some cases. The duration of relief can depend on factors such as the severity of the osteoarthritis, the individual’s response to the treatment, and their level of physical activity.
Hyalgan works by injecting hyaluronic acid directly into the knee joint, replenishing the natural lubricating fluid that has been lost due to osteoarthritis. This reduces friction, alleviates pain, and helps restore smoother movement in the joint.
Common side effects include mild pain, swelling, or redness at the injection site, as well as minor bruising or skin irritation. Some patients may experience headaches, nausea, or rare allergic reactions. It’s important to inform the doctor if you have poultry or egg allergies, as Hyalgan is derived from rooster combs.
