Before anyone has a total knee they need to try this product. It has a lot of research out of John Hopkins. It is called "Bionicare" . It is a non-invasive treatment for Osteoarthritis of the knee. It is FDA approved and paid for by Medicare in most regions of the U.S.. There is nothing like it on the market, one of a kind treatment. The success stories are amazing and in most cases it has given people back their lives. It reduces pain and restores function that has been lost due to years of osteoarthritis. My recommendation is that if you are looking for answers besides a total knee replacement and have tried medication, rehab, injections, etc, I suggest you look into this as another alternative. I have a friend that has distributed this product for a few years and his patients have a 80% success rate.
