@Rednucleus Here is my story, short version. I'm 65, I have had ostearthritis in my shoulder for some 35 years now. Last year it got so bad that I could not raise my arm past my waist without severe pain. My very good friend, who is a well respected orthopedic surgeon specializing in everything from the shoulder to the fingers and has put me back together longer than I can remember, was my firt stop. Over the last 20 years he has cared for my shoulder with various surgeries and lubricating injections. When I went to him last winter he told me I needed it replaced. Had xrays and MRI's and the radiologist told me she has never seen such a trashed out shoulder, no cartilage, 75% torn supraspinitus, no spacing, etc.. I asked my friend about stem cells and he said "it wasn't there yet, and anyways you are so trashed I doubt it be of benefit. Even though he was my friend I went for a second and a third opinion and they said same thing, replace it. The third guy was the top shoulder guy in Chicago, and he said he would do the stem cell if I really wanted to but it was probably a waste of money. Regardless, I booked an appointment.
Then chance would have it I met another Dr., this guy was sports medicine, not a surgeon, and he is totally committed to this avenue as the future of Orthopedic medicine. Although he also said my shoulder was totally trashed, worse he's seen, and there was no research that would indicate it would be of benefit. But he was so knowledgeable, and refreshing to talk to that I booked the appointment with him, even though he was twice the cost, and cancelled the "expert".
As I said, for me it was a miracle. It is not an instant cure, and not a cure for the arthritis at all. I'm really not sure what it does,but it worked for me. Over a six month period it got stronger and stronger. At six months you get to full benefit. So now I have a shoulder that still does not have full range of motion, but the range I do have is pain free and strong. I can live with that. I can ski, I can lift weights, I can throw a ball, etc. He used my own bone marrow stem cells and my own fat stem cells.
I do not know if it is a permanent fix, and if the symptons come back I will do it again. But for me it was an easy decision, shoulder replacement or try the stem cells. If it doesn't work then I'm out a couple thousand bucks, kind of like buying a ski you wish you didn't. But it worked. My buddy the surgeon was shocked, and told me he didn't think I would have gotten any more function with a replacement. He was very surprised at the result but happy for me.
So that's it, oh yeah, I took a lot of PT afterwards from some very well trained therapists.
