I have a problem with my left knee. I have been told that this knee is bone on bone. I do not particularly want to have a knee replacement. I have heard that stem cells injected into the knee may be better than replacement of the knee. Can you tell me more about this new procedure? Barbara W.
Dear patient if your left knee is showing bone to bone on X-ray total knee joint replacement is the best option. Stem cell therapy is the new edition to the treatment of early osteoarthritis and those patients with local cartilage defect.  Bone to bone on X-ray means near complete loss of joint cartilage which cannot be replaced. Total knee replacement has now excellent results and is time tested surgery. You should not be worried.
