Barbee, 54, discovered that she had an appreciable loss of cartilage and she could not put up with the loss of mobility and pain any longer. She decided to have a stem cell injection instead of surgery. Adult stem cells were harvested from her bone marrow and injected into the degenerated area. Orthopedic physician Dr. Ron Hansen joins “The Doctors” to discuss the procedure and show the results of Barbee’s stem cell injections.
