Doctors explain how Lindsey Vonn can ski at

MILAN — One short week after Lindsey Vonn crashed in Crans-Montana, Switzerland, and tore her left anterior cruciate ligament, she was tearing down the hill in Cortina d’Ampezzo, Italy, a gentle knee brace warping the material of her racing go well with the only apparent signal of something amiss. When she completed the training run Friday, clocking the third-fastest time for a U.S. girl on the day, she casually fist-bumped an American teammate at the end line.

She made the feat look easy. Sports drugs consultants can say it’s something but.

“It’s atypical to be able to compete without an ACL, at anything, but especially at a high level like Lindsey Vonn’s going to compete at,” said Clint Soppe, a board licensed orthopedic surgeon and sports activities drugs specialist at Cedars-Sinai. “So this is very surprising news to me as well.”

The ACL, which connects the shin bone to the femur, is a main stabilizing pressure in the knee and protects the decrease leg from sliding ahead. Straight-line motion doesn’t stress the major knee ligament and some day-to-day duties such as strolling are simply achieved without an ACL. But what Vonn is doing is much from regular.

“If you add cutting, pivoting, changing directions, in 95% of humans, you need an ACL to do that,” said Kevin Farmer, an orthopedic surgeon and professor at the University of Florida’s division of orthopedics and sports activities drugs. “She’s obviously fallen into that 5%.”

Farmer calls the uncommon group “copers.” They overcome the dearth of an ACL by strengthening and partaking other muscle mass. It’s primarily the hamstrings and quadriceps, but all the pieces, including the glutes, calves, hips and core, counts.

Vonn could have had just 9 days between the Olympic downhill race and her injury when she stands at the start gate Sunday. But the 41-year-old has had her complete profession to develop the kind of strength and control vital to carry her through the Games without an ACL. She’s already achieved it before.

Vonn skied on a torn proper ACL for more than a month until withdrawing just before the 2014 Sochi Olympics. In 2019, she gained a bronze medal at world championships without a lateral collateral ligament and three tibial fractures in her left knee. She said this week that the same knee feels better than it did during that bronze medal run.

“She’s dealt with knee injuries in this knee before, so she’s been able to develop mechanisms and strategies,” Farmer said. “She probably doesn’t even realize that, but just from years of practicing with a knee that’s not normal, her body has developed mechanisms of firing patterns that allow her knee to have some inherent stability that most people don’t have.”

For athletes who endure major accidents for the first time, pain often prevents them from firing their muscle mass, said Jason Zaremski, a nonoperative musculoskeletal and sports activities drugs doctor and medical professor at the University of Florida’s division of bodily drugs and rehabilitation. But Vonn, whose injury historical past is nearly as long as her resume, appeared calm during training, her coach Aksel Lund Svindal told reporters in Cortina on Saturday.

So even if she’s one ACL short, Vonn’s staff is aware of she has more than enough of the intangibles to get her not only down the mountain, but into medal rivalry.

“Her mental strength,” Svindal told reporters in Cortina on Saturday. “I think that’s why she has won as much as she has.”

Vonn accomplished her second training run Saturday with the third-fastest time before training was suspended after 21 athletes. She was 0.37 second behind compatriot Breezy Johnson, who is intimately acquainted with what Vonn is trying.

Johnson, a medal contender for the United States who led the second training run at 1 minute and 37.91 seconds, tried to ski in Cortina without an ACL in 2022. She had one profitable training run, but crashed on the second one, sustaining additional accidents that compelled her to withdraw from the Beijing Olympics.

Johnson, like many, gasped when she noticed Vonn’s knee buckle barely on a leap during training Saturday. She said coming off jumps on this course are particularly troublesome.

“There are, I think, more athletes that ski without ACLs and with knee damage than maybe talk about it,” Johnson said at a news convention from Cortina. “… I think that people often are unwilling to talk about it because of judgment from the media and the outside.”

Critics say Vonn is taking a spot from a healthy teammate or that she merely refuses to give up the game for good. But Vonn has already come to phrases with the end of her profession. She said she got here out of retirement with a partially changed proper knee merely wanting an alternative to put the right bow on her ski racing profession at a course she particularly loves.

The stage is different, but the sentiment is acquainted to Zaremski. The doctor has labored with high college athletes who beg for a likelihood to play a ultimate recreation after struggling a torn ACL. Through bracing, taping and treatment, sometimes there are short-term fixes for the most important moments.

“If we’re trying to get a huge event like the Olympics, I would never put anything past [Vonn],” Zaremski said. “She’s an amazing, once-in-a-generation athlete.”
