Lindsey Vonn of the United States of America skis before crashing while competing in the Women's Super G event during the Alpine FIS Ski World Championships in Schladming, Austria, on Feb. 5, 2013.

US Olympic gold medalist Lindsey Vonn was airlifted off a slope at the Alpine Ski World Championships in Austria today after crashing during the super G, CNN reported.

The hospital that’s treating Vonn said she has a "complex knee injury," according to CNN.

Vonn, 28, a four-time overall Alpine Ski World Cup champion, lost balance after landing a jump, the Associated Press reported.

The skiing conditions have been challenging on the opening day of the World Cup, and the race had been delayed by three and a half hours because of fog, the AP reported.

"It's not a very difficult course, but in some parts you couldn't see anything," Fabienne Suter of Switzerland told the AP.

According to the AP:

All through her career, Vonn has been slowed by injuries at major championships - crashes and concussions; a sliced thumb and bruised shin.
