I was advised that I need knee replacement due to arthritis , bone on bone and my lower leg rotating ...I need help deciding . My knee is locking up on me and causing back pain and my good leg to hurt. I am interested in stem cell therapy as I am scared to death about any kind of surgery. Who do I talk with, how much does it cost, how long is the wait time,how long is my down time is there any guarantee of a length of time this should work and if they do the therapy and it doesn't work would I not be able to repeat the therapy or am I destined for surgery of knee replacement. If you dont this where do I go for this procedure .Thank you in advance.
