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. The clinical side of the same treatment is described in hyaluronic acid injections for knee pain.
- They work best for knee osteoarthritis, where cartilage has worn and the joint needs cushioning.
- Cost depends on the plan. Many plans, including Medicaid managed care, cover them, and coverage can be verified before a visit.
- The injection takes a few minutes and is done in the office.
- They are available 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 the insurance plan. Many plans, including Medicaid managed care, Healthfirst, Fidelis Care, MetroPlus, and Medicare, cover gel injections when they are medically appropriate. Rather than guess, it is worth having coverage verified before a 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 the knee pain has another cause, that evaluation should point toward 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?
Many plans are commonly accepted, including Medicaid managed care, Healthfirst, Fidelis Care, MetroPlus, and Medicare. If it is not clear whether a plan covers gel injections, that is worth checking before a visit.

Frequently asked questions
How long do gel knee injections last?
It varies by person and product. Many people get several months of relief, and the course can be repeated. A clearer picture usually comes after an assessment.
Are gel injections the same as cortisone?
No. Cortisone reduces inflammation; gel injections lubricate and cushion the joint. They serve different purposes, and a clinician can help weigh which one fits.
Are gel knee injections repeated on a fixed schedule?
Usually they are given as a course and then reviewed, rather than repeated automatically. How soon a further course is considered depends on how long the benefit lasted and what the joint looks like at review. Insurance plans also apply their own limits on frequency.
Do gel knee injections work for every type of knee pain?
No. They target osteoarthritis, where joint lubrication and cushioning are reduced. Knee pain from a ligament tear, a mechanical block inside the joint, or pain referred from the hip or lower back is a different problem and is treated differently.
