In October, four months before she could defend her gold medal in aerials, Australian skier Alisa Camplin blew out her right knee. On the day after surgery, still in her hospital bed, Camplin worked out to an exercise video. “Leg lifts and butt lifts,” she said. On the second day, she tossed aside her crutches. On the third day, she hit the gym. After three months, she hit the slopes, with a knee surgeons cautioned could take at least seven months to heal. “It could have been so mushy it would have popped out the first time I was on skis,” she said. “I wouldn’t have had any regrets.” Qualifying runs are Sunday. Her chances? “I’m not here to be an Olympic tourist,” she said.
