U.S. Olympic alpine skier Lindsey Vonn returned to the slopes Thursday for the first time since re-injuring her knee in December 2013.
Vonn announced in January that she would not be competing in the 2014 Winter Olympics in Sochi because of the injury.
In February 2013, Vonn tore her ACL and MCL at the World Championships. She said she would be ready in time for the Olympics, but in November she sustained a partial tear in the same ACL before returning and injuring it again one month later.
Vonn won a gold and bronze medal at the 2010 Olympics in Vancouver, becoming the first American woman to win the gold in the downhill competition.
The skier also is one of just two women to win four World Cup Championships, and she won gold in the Downhill and Super G at the 2009 World Championships.
Vonn posted a photo on her Instagram Thursday with the following caption: "After a looong 9 months I'm back on snow!! It was definitely worth the wait!! cool videos to come :) #iloveskiing #gopro #hero4"
