I am a 77 year old woman with arthritic knees where it’s difficult for me to walk and I’m trying to avoid knee replacement. I have done the Synvisc injections and physical therapy– to no avail. Is there anyone here who has had stem cell therapy for arthritic knees and I would like to know your outcome. I know there are two, one where bone marrow is removed and the other where they take fat from the abdomen and regenerate and inject into the knees. I would like to know the cost and how long the procedure takes and any other information which would be helpful to me. I live in North Jersey and am currently looking for clinics in my area who perform this procedure. I appreciate your help.
