I was asked by one person the cost of stem cells and location . I will say that its the wild west out there and many drs are offering stem cells from baby tissue etc. That is a waste of money. If you have it done use your own cells. The cost was $7000 in those days. I do feel that PRP has worked the best along with the rebound cartilage brace. I do not go anywhere with out my brace. Works great. The PRP i have done once every year or every two years and the cost is around $1000. In my way of thinking, it is worth it not to go through the operation and the recovery. To each his own. My Dr is in NW OHio , Dr Kruse. He works with regennex who is out of Colorado. I did have the PRP done on my back for an L4 and L5 and i have had 0 pain since , and that has been over 5 years. No pain, no operation. Must be something to having the body heal the body. For PRP you take off a few days up to 2 weeks. I know people say to me no insurance covers it. WE are seeing in our area insurance covering the procedure. I say i would rather spend the money than the option of surgery.
