Based on investigating stem cell therapy myself, although for something very different from knees, you need to break down your decision-making into two parts:
1. Can stem cells actually work?
It’s an “investigational” or “experimental” treatment for most conditions, which is the main reason it’s hard to get insurance to pay. In terms of research, the picture is murky. Remember that knowing some guy who ... doesn’t prove anything. They are being used for many issues where they seem to be not just useless, but can have serious side effects, such as the eyes.
But joints (like the knee) seem to have a more solid record for success than other applications closer to vital organs, and much less danger of negative side effects.
2. Who is going to do it?
Be very careful of commercial stem cell clinics whose websites and literature lure you with lots of happy stories of folks who were on crutches and are now running marathons. There are a lot of shady operators out there, and just because there are M.D.’s with impressive-sounding credentials involved, does not guarantee anything other than it’ll be pricey. Doctors need money, too.
So do your research, ask your personal physicians, and don’t just take advice from friends and strangers on internet forums!
