I had it done at U of C after I read this article.

"Through this study, UChicago Medicine became the first hospital in the Midwest — and among the first in the country — to offer GAE. In the past two years, UChicago Medicine doctors have performed more than 100 of these procedures with overwhelmingly positive outcomes, said interventional radiologist Osman Ahmed, MD, who led the clinical program."

I had some bruising and discoloration on my knee, but three months out, almost to the day, almost entirely cleared up. Also, no swelling now. I didn’t have much, swelling, though. I used an ice pack for the swelling.

My bruise was right near the catheter insertion point. It was maybe 3 or 4 inches on my inner thigh. I used arnica cream and it helped. Sadly, GAE did not help my knee but it had already been replaced.
