(CNN) Lindsey Vonn is not giving up yet.

Plagued by injury in recent years, the 34-year-old American had hinted at retiring after being forced to compete at Cortina wearing braces on both knees.

Vonn's appearance at the Italian event last week, where she had won 12 World Cup races, was her first since suffering a knee injury while training at Lake Louise, Alberta, in November.

Clearly struggling with her knee problem, Vonn could only muster a 15th place finish in last Friday's downhill and ninth in Saturday's race.

Asked whether she had already taken part in her final race, she told reporters: "I think so ... but I must think about it."
