Lindsey Vonn shocks fans with high-intensity training video days after rupturing ACL

It is a medical report that would end the season for any other athlete: a completely ruptured ACL, bone bruising, and meniscal damage.

But for Lindsey Vonn, it is simply the latest obstacle in a career defined by them.

Just one week before her highly anticipated return to the Olympic stage at the 2026 Milan-Cortina Games, the 41-year-old American legend has stunned the sports world by refusing to withdraw.

Instead, she is already back on the slopes, testing her stability with a heavy-duty knee brace and the ultimate competitor’s mentality, that has even seasoned orthopedic surgeons shaking their heads in disbelief.

The crisis began last Friday during a World Cup downhill in Crans-Montana, Switzerland. Vonn lost control landing a jump, hurtling into the safety netting at high speed. While she was able to gingerly ski to the bottom, she was eventually airlifted to a hospital.

On Tuesday, standing tall and remarkably without a limp, Vonn addressed a packed room of reporters in Cortina to confirm the severity of the injury.

“I completely ruptured my ACL,” Vonn said. “I also have bone bruising… plus meniscal damage. But my knee is not swollen, and with the help of a knee brace, I am confident I can compete on Sunday.”

On Thursday, just one day before the Opening Ceremony, Vonn shared a workout video that went viral across social media.

Set to Andy Grammer’s “Don’t Give Up On Me,” the footage shows Vonn performing weighted squats, rapid-fire box jumps, and lateral lunges—movements that require extreme ligament stability.

She captioned the video: “I’m not giving up, working as hard as I can to make it happen! Thank you to my team and everyone for your incredible support. Keep believing.”

What makes this comeback even more surreal is that Vonn’s other knee, the right one, is partially made of titanium.

Following her 2019 retirement, chronic pain led to a robot-assisted partial knee replacement in 2024. That surgery was meant to help her walk without pain; instead, it felt so good that it fueled this 2026 Olympic bid. Now, she is effectively competing with a prosthetic right knee and a ligament-less left knee.

The International Ski and Snowboard Federation (FIS) rules are strict: Vonn must complete at least one official training run to be eligible for Sunday’s Downhill.

With Thursday’s session scrapped due to 20 centimeters of fresh snow and low visibility, she now only has two windows remaining: Friday and Saturday.

Experts, like Italian Winter Sports Federation chief physician Andrea Panzeri, note that while rare, elite athletes can compete without an ACL if their secondary muscles are strong enough to compensate.

Vonn, who has gained 12 pounds of muscle since her return, believes she is ready.

Despite the delay, Vonn appeared in high spirits on Thursday, spotted at her favorite local pizza spot in Cortina—a place where she has historically enjoyed a record 12 World Cup victories.

“When I stand on a starting gate again, I’m not going to be thinking about my knee,” Vonn said. “I’m going to be thinking about skiing fast.”

She is already the most decorated female downhill skier in history, but a medal on Sunday would make her the oldest Alpine skier to ever reach an Olympic podium.

“I know my chances aren’t the same as they were before the crash,” Vonn admitted. “But as long as there’s a chance, I will try. This would be the best comeback I’ve done so far. Definitely the most dramatic.”

As the world watches the slopes of the Tofane Alpine Skiing Centre this weekend, the result almost seems secondary to the feat itself.

Whether she reaches the podium or not, Lindsey Vonn has already made it clear: she’s playing the hand she was dealt, and she isn’t folding.
