I had a knee replacement three years ago on the right knee. It still is swollen, and bottom line it did not work for me. In my discussions with others I would say 3 out of 10 have trouble. I swore I would not do that again. My left knee was bone on bone but I heard of stem cells. Last January I did stem cells on my knee. They use my stem cells. I was referred by a female friend who had both knees done with stem cells. The difference is I have full mobility,very little pain and I can knell on my knee in gardening etc.
next I did my back which had an L 4 L 5 rubbing on my nerve. I had an injection to stimulate the stem cells.4 weeks later, no pain, fullmobility, back playing golf,pain free. The downside is the procedure is out of pocket. I would do it again . I have friends who have had their hip injected. There is no hospital stay, I used no pain pills. I wish it was available before I did the knee replacement.
