Doctors at a hospital in London performed a groundbreaking procedure on a 42-year-old patient whose elbow was shattered in a car accident 15 years ago. The five-hour procedure involved resculpting the elbow bone and then grafting tendon tissue from a donor onto the joint. Doctors hope the procedure will promote the regrowth of tissue, and patient Jo Macleod said she wants to help raise awareness of the importance of tissue donation. "My operation may not be life-saving but it's definitely life-changing. It's offered me the hope of a life without pain," Macleod said.
