TL;DR
Gel injections, also called hyaluronic acid injections, add a lubricating, cushioning fluid to a worn knee joint to ease pain and improve movement. For the right patient, they are a non-surgical option worth considering.
- They work best for knee osteoarthritis, where cartilage has worn and the joint needs cushioning.
- Cost depends on your plan. Many plans, including Medicaid managed care, cover them, and we check your coverage before your visit.
- The injection takes a few minutes and is done in the office.
- We offer them across Brooklyn, the Five Towns, and Monsey.
If knee pain has you weighing your options and you would rather avoid surgery, gel injections may be part of the conversation. They are a common, non-surgical treatment for a worn, painful knee.
What are gel (hyaluronic acid) knee injections?
Gel injections, also called hyaluronic acid injections, add a thick, lubricating fluid to the knee joint. Healthy knees already contain this fluid; in a worn or arthritic knee it thins out. Replacing it can cushion the joint, reduce friction, and ease pain so you can move more comfortably.

How much do hyaluronic acid knee injections cost?
The honest answer is that it depends on your insurance. Many plans, including Medicaid managed care, Healthfirst, Fidelis Care, MetroPlus, and Medicare, cover gel injections when they are medically appropriate. Rather than guess, contact us and we will verify your coverage before your visit so there are no surprises.
Do gel injections for the knee work?
For the right patient, yes. They tend to help most with knee osteoarthritis, where cartilage has worn and the joint needs cushioning. They are not the answer for every knee, which is why an assessment comes first. If your knee pain has another cause, we will point you to the treatment that fits.
What to expect during and after
The injection is done in the office and takes only a few minutes. Most people return to their day right after, with any soreness settling quickly. Depending on the product, treatment may be a single injection or a short series, and relief tends to build over the following weeks.
Do you accept my insurance?
We work with many plans, including Medicaid managed care, Healthfirst, Fidelis Care, MetroPlus, and Medicare. If you are not sure whether your plan covers gel injections, contact us and we will check before your visit.

It varies by person and product. Many people get several months of relief, and the course can be repeated. We give you a clear picture after your assessment.
