You are correct about scammers. The scammer buy stem cells from sales people and the cells are dead. I worked with a dr who was trained by Regenexx and i had knee and my back done. I had great success. My TKR was a disaster. Work out in water the knee swells. Been 6 years and my TKR is twice the size of my stem cell knee. I wish i had a do over. My stem cell knee was one of following directions. The cells were taken from my hip and mixed with my blood for 3 hours. Then injected in the knee. Took 10 days of lying around reading and watching TV. Never took any pain pills. It took time but i can do everything but play tennis. Golf, gardening, down on my stem cell knee, biking etc. No swelling. I am still seeing my ortho dr about the TKR swelling and pain and i get a good shoulder shrug. The orthos who work in same hospital as stem cell dr continue to bad mouth it, but now Promedica is now covering all their employees for stem cells with Regenexx. Other insurance companies are also covering it. I wish i had a do over on the TKR . I know many have success but judging by what i read many do not. I was told , yes tennis and all the activity you did before. I now walk down my steps backwards to avoid the pain. Pretty good at it. I learned about stem cells from Mayo and its use on arthritis. I found out about DR Kruse in Toledo and i am happy with my results. I would recommend people interested to go Regenexx web site. They keep all the data on their success and failure rates. My friend had his hip done and was told it was a 50 50 chance. They were honest with him. He is happy with the results.
My back had an L4 and a L5 rubbing on the nerve. 2 friends had the same and had operations twice and did not work. I had the injection and within weeks i noticed the difference,
Bottom line, do your homework. Do not go to drs who buy stem cells. Chances are they are dead. Use your own and stay away from meds and pills that kill your stem cells and their are many. Good luck
