Lindsey Vonn revealed on Monday that she came close to losing her left leg to amputation following her crash at the 2026 Winter Olympics in Cortina d'Ampezzo — disclosing for the first time the full severity of an injury that required emergency surgery performed on the mountain within minutes of the fall.

“He filleted it open and let it breathe, and he saved me.”

Emergency Surgery on the Mountain

Dr. Hackett, an orthopedic surgeon who works with Vonn and the U.S. Ski & Snowboard team, performed an emergency fasciotomy — slicing open both sides of her calf to relieve crushing pressure building inside the muscle compartment and restore blood flow to the limb. “He filleted it open and let it breathe, and he saved me,” Vonn said.

The procedure was necessary to treat acute compartment syndrome — a dangerous complication in which swelling inside a closed muscle compartment cuts off circulation. Without intervention, the condition destroys muscle and nerve tissue within hours and, left untreated, forces surgeons to amputate the affected limb entirely. The decision to operate at the crash site rather than wait for hospital transfer almost certainly made the difference between saving and losing the leg.

What Is a Fasciotomy?

A fasciotomy is one of the most urgent procedures in trauma surgery. The fascia is the dense connective tissue sleeve that wraps around muscle groups. In a severe impact, bleeding and swelling inside that sleeve can generate pressure high enough to collapse blood vessels — effectively strangling the muscle from the inside. Cutting through the fascia immediately decompresses the compartment and allows tissue to survive.

Performing the procedure in a field setting, on a mountain, without a sterile operating theater, requires significant skill and decisiveness. Dr. Hackett's call to act immediately rather than wait for evacuation reflects the narrow time window that defines whether compartment syndrome results in recovery or permanent loss.

Acute compartment syndrome requires fasciotomy within 6 hours of onset to prevent permanent muscle and nerve damage. Delay beyond that window significantly increases the risk of requiring amputation.

Vonn's Recovery and the Road Ahead

Vonn, 41, had already been competing at Milano Cortina 2026 on a torn ACL — a fact she had publicly disclosed before the games. The crash compounded those injuries significantly, and the fasciotomy leaves her calf with open surgical wounds that will require staged closure and a lengthy rehabilitation. The full implications for her athletic future remain unclear, though Vonn has consistently refused to discuss retirement in definitive terms.

What is clear is that without Dr. Hackett's immediate decision to operate on the mountain, the conversation today would be an entirely different one. For Vonn — who has now had more than nine major surgeries across a career defined as much by its comebacks as its championships — this is one more chapter written not in victories but in survival.
