Osteoarthritis
"Not sure why all of these negative experiences.  59 years old with osteoarthritis in both knees, bone on bone inside left.  Arthroscopic surgery two years ago to clean left helped with swelling and some pain.  Taking shots every six months in both knees for two years.  Definitely works.........  received my black belt in martial arts earlier this year and never would&#039;ve accomplished that without the shots."
