Growing Artificial Limbs

The article is about a woman from New Hampshire who sent her cells to a laboratory where scientists regrew her cartilage in her knee. She had such intense pain before surgery that she couldn't drive or walk up stairs; however, after the surgery with the artificial limb, she is able to do these things. This allows her to walk and drive like she could many years ago, but this is not the "original" her.

Should people be allowed to have artificial limbs attached to them? What effects could this have on society?
