“I sustained a complex tibia fracture that is currently stable but will require multiple surgeries to fix properly,” she said.
She continued: “My Olympic dream did not finish the way I dreamt it would. It wasn’t a story book ending or a fairy tale, it was just life. I dared to dream and had worked so hard to achieve it.
“Because in Downhill ski racing the difference between a strategic line and a catastrophic injury can be as small as 5 inches.”
Vonn gave no indication whether she intends to bring an end to a career that has made her one of the most recognisable faces in world sport.
She has already had two surgeries to stablise the fracture of her left leg, according to reports in Italy.
Vonn won the Olympic downhill at the 2010 Vancouver Games but retired in 2019.
She had resumed her career in late 2024 and was considered a strong favourite for the downhill at these Olympics after recording seven World Cup podium finishes, including two wins, before her pre-Olympics crash in Crans-Montana, Switzerland, where she damaged her ACL.
