There are few side effects of stem cell therapy because of the use of a patient’s own cells and its minimally invasive nature. There is no rejection to cell products and a patient only has some mild tenderness for a few days following the procedure. Unlike surgery, patients never lose their mobility while resuming activities of normal living very rapidly. There is a very low rate of infection and no concerns for blood clots or pneumonias as seen with surgery. Finally, unlike surgical changes, if the procedure is ineffective for the patient then they still have all options open as they are never worse than prior to the procedure.
