She didn't waste any time, either, taking two runs shortly after she landed Aug. 31.
"I was definitely pretty amped to get on snow," she said. "It was a long wait for those first couple of runs, but it was definitely worth it."
Vonn said her knee held up perfectly, with no pain or swelling while she was in Chile - or since then.
"Things are definitely further along than I anticipated," she said. "But I'm not going to race until I'm absolutely 100 percent."
And that last hurdle is purely mental.
Vonn doesn't expect to race slalom because of the additional stress it puts on her knee, and is focusing instead on the downhill and speed events, her specialities. But she isn't back to race speed yet - no small thing for someone who easily can hit 80 mph as she hurtles down the mountain.
Vonn is in Ohio, where boyfriend Tiger Woods is playing in the Presidents Cup. She plans to head to Europe in the middle of the month for more training, and said she'll probably make a decision about Soelden "a few days" before the World Cup begins.
If she doesn't race in Soelden, she'll "for sure" be at the World Cup in Beaver Creek, Colorado, which is near her hometown of Vail.
The Sochi Games may have looked like a long shot when Vonn was injured. But she has no doubt that not only will she be at the Olympics come February, she'll once again be the one to beat.
"I know I can win a medal," she said. "I look forward to defending my title in Sochi."
