So in 2008, he found a surgeon who agreed to shorten the right one so that his legs would be equal. But the surgery was botched: The knee joint was put back in the wrong position, and one of the screws they used to hold the joint together came loose. During a second surgery, the doctor discovered another problem with the first surgery, which required a third one. That one was slightly botched, too, requiring a fourth.
