that's my concern also! I'd like to know! if GAE can be repeated once successful, maybe I'll age out of a TKR. LOL

when I consulted with Dr. Padia's associate, I was told they wanted to prove it works and get insurance companies to pay for it. I was on the wait list, meaning at the end of a year I would get the procedure. I was in too much, too often regular pain and had another consult with another radiologist who told me, go see a surgeon. so now I'm 5 months post a tkr. I hope more is known and understood about GAE so I can use it on other knee rather then TKR when the time comes.
