Let me tell you about a new study where physicians are trying to grow cartilage and put it back into your knee to replace areas that have worn away from traumatic injury or maybe from arthritic wear and tear. This study amongst a host of other studies show that this surgery is often very, very successful to try to regrow cartilage over the end of the bone to eliminate pain and to restore function back to a more normal knee. And that’s important for all of us because these new technologies are not out there in the future. These are things that are here today that we can help you with to change your knee works and give you back the life you once had.
