The GAE procedure helped a lot. I have less knee pain and can enjoy being myself again. I had a great experience [with North Star], and I look forward to getting my right knee done!
Genicular artery embolization (GAE) is a minimally invasive, FDA-approved treatment for knee osteoarthritis (OA). It requires no surgery, no hospitalization and no lengthy recovery. It is highly effective at relieving pain, and if you seek GAE treatment for OA early enough, you may not ever need surgery for your condition.
GAE works by targeting the abnormal blood vessels within the synovium that are responsible for inflammation and cartilage loss. By embolizing or “blocking” these abnormal vessels, blood flow is reduced to normal levels. Pain is significantly reduced, and cartilage loss is halted or significantly slowed.
During the procedure, one of our interventional radiologists uses imaging to guide a catheter through the vascular system and to the genicular artery feeding the synovium. Tiny particles are injected that block the flow of blood through the abnormal blood vessels within the synovium, which in turn decreases the inflammatory mediators that the synovium secretes. The result is fast and long-term pain relief, as well as improved function and quality of life. Additionally, it does not preclude the ability to have knee replacement surgery in the future.
A clinical study performed in 2021 demonstrated that the average pain scores decreased from 8 out of 10 to 3 out of 10 within the first week of the procedure.1
Genicular artery embolization for knee osteoarthritis treatment is recommended for patients who:
- Are 40-80 years of age
- Have moderate to severe knee pain
- Are diagnosed with osteoarthritis based on X-ray or other imaging, but without bony deformity/sclerosis
- Experience local knee tenderness
- Have resistant or failed conservative treatment (medication, physical therapy, joint injections)
Frequently Asked Questions (FAQ) for GAE

[After PAE] to treat my enlarged prostate, I can go hours now without going to the bathroom. I don’t get up at night to pee anymore. Guys, you’ve got to try this! It really works!
Totally painless and with no bleeding or other complication. Had the desired outcome and highly recommended prostatic artery embolization for BPH and as my urologist observed Dr. Golzarian is the most experienced interventional radiologist for doing this procedure in this country.
Ok. So, first off, awesome crew.
From consultation to day of, I was given clear explanations, my questions were answered. Moe was awesome at checking me in. Kelly, Sandra and Sarah are super pleasant and comforting nurses. They made sure I was comfortable, (played my favorite music) had assuring words and made sure that I knew and understood everything they were doing. Andy, the PA, was very knowledgeable and answered my questions clearly and precise. Dr. Astani was wonderful.
I got the best treatment from North Star.
North Star is the best in Minnesota! The staff is so friendly and treat you like family. And Dr. Golzarian is great! I thought I would have to live with knee pain for the remainder of my life. But Dr. Golzarian has made sure I don’t! Not everyday is totally pain free. But I can walk freely, I can get up off the couch without hesitation. I no longer have to rub my knee before making any sudden movements. Thank you North Star!!!
I definitely am glad that I gave them my trust to provide me with the amazing experience that I had when I came in to have my procedure done I was very concerned because I have extreme vertigo that has been disregarded by previous medical professionals. That did not happen whatsoever when I came in for my procedure with North Star Vascular! When I was speaking with my prep team over the phone, she made sure that she was able to provide the best care for me. And they did. Throughout the prepping and the procedure they were attentive, accommodating, and the most caring team I have ever dealt with. I can’t wait for my follow-up visit so we can schedule my other knee procedure. I went from a resting level pain of eight in my right knee, which is the worst or actually was the worst to a resting pain of zero I can climb stairs, I can walk , literally pain-free and that was the second day after surgery. I feel strongly that you can put your trust into North Star Vascular and Dr. Golzarian and his team! I can’t stress enough the amazement and delight to be pain free! Take a chance—-you won’t regret it!
Yesterday, Dr. Golzarian operated on my right knee, which had severe arthritis. Now that 24 hours have passed, I feel like I’m in my twenties when I’m exactly 80 years old. I just don’t know and can’t express my gratitude to you and your dear colleagues. I think you performed a miracle. All the orthopedists I went to for my knee bone wear unanimously said that they should replace with an artificial knee. But now I am walking without any pain and my blood pressure is rising. I just wanted to say that I thank you and your colleagues at North Star from the bottom of my heart.
After GAE on my left knee I now can go and walk around the store with my family, I haven’t done that in years. Something as simple as stepping over a curb is possible now and without pain. I can’t wait to have my second knee done!
Excellent experience, knowledgeable and caring staff! Feels like they turned back the clock 5+ years on my knee!
Dr. Golzarian, thank you for the very good procedure you did to treat my knee osteoarthritis, when all the other doctors wanted to give me an artificial knee because of the advanced osteoarthritis. You gave me the hope of walking again without pain after two hours of performing GAE on my knee. I am 80 years old. I am old, for the first time in six years, I was able to walk again without pain after the procedure, I was able to go up and down the stairs. For this reason, while thanking and appreciating you and your skilled colleagues, I want you to know that I am always grateful to you. Thank you.
