Genicular Artery Embolization for Knee Pain

Posted by rosesimpkin @rosesimpkin, Apr 3, 2025

I had a TKR three year ago and still have new pain.
I was offered a GAE ( Genicular Artery Embolization)
Does anyone know anything about this

@zephyr2309 Thanks! Did insurance cover it?

Yes, it was covered by insurance. I did have a co-pay, however. But it was minimal compared with to the cost of the procedure. Six months out, the knee is feeling great. Thinking about doing the other knee next year.

New embolization done two days ago. Much less swelling of the knee. Of course elevation and icing has helped. I am able now to bend my knee with minimal pain. A major improvement. The incision site was on my ankle. I will post again in a few weeks. So far I am pleased with procedure.

Congratulations! I had two GAEs in June and Sept and knee is still stiff and painful.

Sorry, you still are uncomfortable. Let me understand, were the GAE both done on the same knee or both knees?

Sorry you’re still experiencing pain. Is there pain in both knees? I had GAE in just one knee, in June. Still a little discoloration, but okay otherwise. Have you discussed with your healthcare provider? i hope you feel better soon.

Both GAEs done on left replaced knee, 3 months apart. Thank you for your encouragement.

Hi - I had my procedure in June 2025. The Sports Medicine physician I’ve seen over the years was keen on me doing the procedure. And it’s been done in Japan, I think for 20 years or so. IDK if there is data to support what the Sports Medicine doctor told you. No one I met with when deciding on the procedure mentioned it. And I’m part of a two- year study of GAE.

@zephyr2309 how does one become part of the “two year study”?

In my case, my physical therapist mentioned the study to me, after the PI of the study met with physical therapists about the study, and recruitment was being undertaken. I contacted the PI (principle investigator) office and initially spoke with a research coordinator, answering some questions. Then I met with the PI, who is also an Interventional Radiologist, after undertaking the required knee X-rays. Based on my history, I qualified for the study and was randomized into one of two arms of the study. So, one would have to find a research study and qualify. In my case, I was informed by my PT and qualified based on the requirements of the study.

Hope this answers your question.

It’s actually a procedure that started in Japan in the early 2000s. My understanding is insurance coverage varies from state to state. I actually qualified for, and participated in a study my physical therapist told me about at UCLA; the interventional radiologist who is the principal investigator on the study gave a presentation as he was enrolling 100 patients. I met with him and his research team in May and completed their questionnaire and x-rays. I’m #77 of 100 qualified participants. I’ll be followed for two years. The purpose of the study is to get the FDA approval for insurers to have to cover it. Now, as noted above, I think it depends on the state and insurer. Four weeks out and my left knee feels great. The interventional radiologist that did mine has done over 300. I told a friend in NY who has been getting injections, and she asked her Ortho about GAE and he referred her to an interventional radiologist. Hope this helps.

I was in the study but when told I was in the 2nd group and would not have the procedure for many months, I went to another radiologist for a consultation, who told me to 'go to a surgeon'. (he wouldn't do the GAE). I was in steady constant pain and could not walk much at all. Soooooooo, I dropped out of the study and had the TKR. I only hope I made the right decision. The decision at THAT time seemed right. I am now 9 months post surgery. I'm still confused, and also confused and often frustrated that I didn't have the nano knee surgery. That consultation did not address the knock knee position due to lack of cartilage (I think) and a friend's son who is head of ER dept at a local hospital recommended the surgeon. I go to zumba most every day, and now the left knee is hurting. I am freaking out!!!! I have appointment at a pain clinic (shoulders, rotator cuffs, and biceps tendonitis issues) also. Gosh, I do NOT want to go through another SURGERY! I will be calling Dr. Padia at UCLA soon. note: the consultation for nano knee told me $8,500. that was scary. But there are still parts of me regretting I didn't go that route.

I was fortunate to have been randomized to the section receiving the procedure immediately, otherwise I would have had to wait six months for the procedure. I’m under the impression only Interventional
Radiologists do the GAE procedure. I don’t know if I would have had the patience to wait six months. I hope you get relief very soon. Best of luck to you!
