When tissue is damaged in the human body, stem cells have the ability to locate the injured area and attempt to repair it by filling in for damaged cells.
Some body parts, like the knee, do not have a sufficient blood supply for the stem cells to penetrate the damage.
In stem cell therapy, stem cells are harvested from the bone marrow or fat, carefully processed and injected into the knee. Shortly after, they will detect the injury and begin their transformation into knee cells to repair the damage. Stem cell therapy is considered to be one of the most promising treatment options available for a host of pain syndromes.
