Hip Replacement Surgery: Mary Lou Retton's Hip Surgery from Biomet

Hip surgery. Isn't that for older adults? Well, that's a common misperception. Just ask Mary Lou Retton. At 38, America's high-energy "Fitness Ambassador" and former Olympic gymnastics champion flashes her famous smile without even a hint of pain these days. It's a full turn from a little more than a year ago, when Mary Lou was in too much pain to even play with her four children, much less stand or sit comfortably.
