If you ever feel a deep, nagging ache in your knee that comes with every step you take, and climbing the stairs or standing up out of a chair has turned into something you have to brace yourself for, this isn’t just another sign of getting older. There are millions of people across the globe that are living with this exact kind of daily knee pain, and for a long time it seemed like the only solution was major surgery. Fortunately, there’s another option worth knowing about, and it’s called genicular artery embolization. It’s a minimally invasive knee treatment that a surprising number of people have never heard of, and it just might be the thing that gives you real relief before you ever have to consider going under the knife.
What is genicular artery embolization, and how does it ease knee pain?
Genicular artery embolization, often shortened to GAE, is a minimally invasive procedure that calms down the inflammation that’s causing your knee pain. When you have knee osteoarthritis, the lining of the joint gets inflamed, and your body begins to grow tiny extra blood vessels that feed that inflammation and the nerves around it.
During GAE, an interventional radiologist makes a tiny pinhole-sized incision, usually in the groin or wrist area, and gently guides a thin catheter to the small genicular arteries that supply blood to your knee. Then microscopic particles are released to slow the blood flow to those overactive vessels. Once that supply is turned down, the inflammation starts to settle, and the pain tends to ease over the following weeks. There’s no cutting into the joint and no tissue is removed, so the natural structure of your knee stays right where it belongs.
Why genicular artery embolization is worth considering for knee osteoarthritis
Knee osteoarthritis is incredibly common, and that’s part of why so many people end up feeling stuck. In fact, there are studies showing that more than one in three people over 60 have signs of knee osteoarthritis on imaging. For decades, the standard treatment moved straight from pills and physical therapy to surgery, and that left a big gap for people who weren’t ready for an operation or for those who weren’t good candidates for one. That is exactly the gap that GAE was made to fill.
The results so far are genuinely encouraging. A large review found that the procedure has a technical success rate near 99.7 percent, with significant, lasting drops in pain and stiffness scores over 12 months. Even better, the relief is lasting, and a long-term study reported that the benefits held steady for at least two years. There are some mild side effects to expect, like temporary skin discoloration or a little bruising at the access site, but serious complications are very rare.
Genicular artery embolization as an alternative to knee replacement
For years, the go-to fix for a badly arthritic knee was a total knee replacement, and this method can work well for the right person. But it isn’t the only option, and that is something a lot of people are never told. As an alternative to knee replacement, GAE doesn’t involve cutting into the joint or removing bone, and there’s no need for general anesthesia, so it’s done on an outpatient basis and most people walk out the same day and are back to normal activities within a couple of days. Compare that to knee replacement surgery, which usually means a hospital stay, months of physical therapy, and a full recovery that can stretch from six months to a year. Also, because GAE is so gentle, you can have it performed more than once if necessary, and it can buy you some real time before surgery ever enters the picture. For some people, that’s enough to put off a replacement for years, and for others it postpones it indefinitely.
Is genicular artery embolization the right knee treatment for you?
Genicular artery embolization is a great option for a lot of people, but it isn’t always the right choice for everyone. It tends to help most when you have knee pain from osteoarthritis that hasn’t responded to things like medication, injections, or physical therapy, and you’d rather hold off on surgery.
There are a few situations where it usually isn’t the best fit, such as if there is an active infection, certain blood vessel problems, or arthritis that is so far advanced that the joint itself is the issue rather than the inflammation around it. The surest way to know is a consultation with an interventional radiologist, who can review your imaging and your history and talk through whether this procedure makes sense for you.
If knee pain is changing how well you can move through your day, please know that there are options available, and you deserve to hear about every single one of them before you decide on knee replacement surgery.

Frequently Asked Questions
What are the disadvantages of genicular artery embolization?
There are a few disadvantages of genicular artery embolization. You can expect some mild bruising at the catheter site, and a small number of people get temporary skin discoloration or a brief ache in the knee afterward. It also doesn’t rebuild the cartilage or repair the joint itself, so for very advanced arthritis it may offer less relief, and some people need a repeat procedure down the road.
What is the success rate of genicular artery embolization?
The success rate of genicular artery embolization is high. Studies report a technical success rate near 100 percent, and the majority of patients see a meaningful drop in their pain and stiffness scores. Clinical success varies a bit depending on how it’s measured, but most people experience real, noticeable relief.
How long does genicular artery embolization last?
For most people, the relief lasts at least a year, and many studies show benefits that continue holding steady out to two years or more. If pain does creep back over time, the procedure can usually be repeated, or you can move on to other options.
Is genicular artery embolization better than knee replacement?
Genicular artery embolization isn’t better or worse than knee replacement, it’s just different, and the right choice depends on you. GAE is far less invasive with a quick recovery, and it’s a great fit when you want to delay or avoid surgery. Knee replacement tends to offer more complete, long-term correction for severe arthritis, but it comes with a hospital stay and a much longer recovery. An interventional radiologist can help you figure out which one fits your situation best.
