Lindsey Vonn is refusing to walk away quietly.
Less than two weeks after suffering a torn ACL, the American skiing legend posted a video of herself lifting weights and running drills — a defiant signal that she still intends to compete at the 2026 Winter Olympics, even as medical experts caution that the task borders on the improbable.
“I’m not giving up 💪🏻 working as hard as I can to make it happen!” Vonn wrote in the caption. “Thank you to my team and everyone for your incredible support. Keep believing 🙏🏻❤️”
The video immediately drew a reaction across the sports medicine community, including from sports medicine doctor Brian Sutterer, who specializes in injury analysis and commented bluntly on the risk.
“Holy…,” Sutterer wrote on X.
Sports Medicine Expert: Competing With Torn ACL Is “Monumentally Difficult”
Sutterer, who breaks down major sports injuries on his widely followed YouTube channel, said Vonn’s goal — returning to elite downhill skiing with an acutely torn ACL — would be shocking if successful.
“If Lindsey Vonn is able to come back and even be somewhat competitive and get through multiple races with an acutely torn ACL, I will be extremely surprised,” Sutterer said. “This is a monumentally difficult — and dangerous — task.”
Vonn ruptured the ACL in her left knee during a downhill crash on Jan. 30, an injury that typically requires reconstructive surgery and months of rehabilitation. Unlike straight-line sports, alpine skiing places extreme rotational and compressive forces on the knee.
“She is flying over hills, landing on angled terrain at high speed,” Sutterer explained. “That places an insane amount of load on the knee. Without an ACL, you’ve lost one of the most important stabilizers of the joint.”
Why Skiing Makes ACL Tears Especially Dangerous
According to Sutterer, elite skiers face unique challenges when attempting to compensate for a torn ACL.
The body can sometimes stabilize the knee through strong hamstrings, which pull the tibia backward and partially replicate the ACL’s function. However, many downhill skiers are quad-dominant, relying heavily on the muscles in the front of the thigh — a pattern that can actually worsen instability.
“That makes it harder to compensate,” Sutterer said.
Compounding the issue, ACL injuries rarely occur in isolation. Meniscus damage, bone bruises, ligament sprains and severe swelling are common. Blood often fills the knee joint, limiting range of motion and inhibiting muscle activation — all factors that compromise stability at speed.
“At the Olympic level, athletes are operating at the 99.9th percentile,” Sutterer said. “The smallest disruption can make or break performance.”
The Greatest Risk Isn’t Performance — It’s a Crash
Sutterer stressed that the biggest concern is not whether Vonn can ski, but whether her knee can hold up in unpredictable situations.
“She might feel okay in practice,” he said. “But one unexpected landing or push-off, and if the muscles don’t fire in time, you can get buckling or pivot-shift episodes.”
Those moments can trigger catastrophic crashes — raising the risk of neck injuries, injuries to the opposite knee, or serious trauma elsewhere.
“A brace won’t help here,” Sutterer added. “At these speeds and forces, it’s mostly psychological.”
Vonn: “I Will Do Everything in My Power to Be in the Gate”
Despite the warnings, Vonn remains undeterred.
She said Tuesday that she skied earlier in the day and felt stable, with no swelling or pain. Her plan is to assess her knee through downhill training before making final decisions.
“I am confident that I can compete on Sunday,” Vonn said of the Feb. 8 downhill event. “I will do everything in my power to be in that starting gate.”
She said her primary focus is the downhill, with decisions on the super-G and team combined events to follow.
“I’m still here,” Vonn said. “I’m still able to fight. I will not go home regretting not trying.”
A Legendary Career Meets One Last Gamble
Vonn’s determination fits a career defined by resilience. She is a three-time Olympic medalist and one of the greatest skiers of all time, with 84 World Cup wins — trailing only Mikaela Shiffrin and Ingemar Stenmark.
Forced into retirement in 2019 by chronic right-knee pain, Vonn underwent a partial knee replacement in April 2024. Feeling pain-free for the first time in years, she began contemplating a comeback.
Now, that comeback has become a high-stakes gamble.
“I hope I’m wrong,” Sutterer said. “I hope I’m eating my words and she’s standing there with a gold medal. But the reality is this is extremely risky.”
At the edge of possibility, Lindsey Vonn is choosing to try anyway — one last push in a career that has never been defined by caution.
