I just saw a young gal with a bad arthritic ankle. She has had stem cells injected with long more pain, but it may be the arthritis itself. I found this website for real patients to discuss their concerns or results. After reading all of this, you want the doctor who performs these procedures, to be something they do all the time, like I am a rehabilitation specialist, they should be regenerative specialists.
