In the center of an intense exercise, Kristina Lazzaro stepped again and heard a sound like a cork popping out of a bottle of champagne.
The 35-year-old Buffalo, New York, resident was doing a accomplice exercise at her native health club, pushing herself to complete sturdy on a shuttle run through which runners dash from one line to a different and again.
Lazzaro exploded off the first line. Arms pumping, she dashed 10 yards throughout the health club to the different line. As she put her foot all the way down to pivot, she heard a popping sound and crumpled to the ground — unable to maneuver her foot in any respect.
“I ended up on the ground, and I didn’t know how I got there,” she mentioned. “There was no warning, no symptoms, and nothing that suggested something like this could happen.”
Lazzaro later realized she had ruptured her Achilles tendon — part of the physique named after a well-known character of Greek legend. It’s a brutal harm with restoration time that may last as long as a 12 months. She sustained the harm on February 6, and she or he’s nonetheless present process bodily remedy.
It appears Achilles injuries are plaguing odd health buffs and a few of the world’s greatest athletes nowadays. Actor Sterling Ok. Brown confirmed as much as this 12 months’s Emmy Awards on a knee scooter after shredding one among his. Achilles ruptures additionally decimated the 2025 NBA playoffs, befalling stars reminiscent of Indiana Pacers level guard Tyrese Haliburton, Boston Celtics ahead Jayson Tatum and then-Milwaukee Bucks level guard Damian Lillard, who now performs for the Portland Trail Blazers.
Recent information suggests the harm is uncommon — about two instances for each 100,000 individuals who checked into US emergency departments between 2001 and 2020, in keeping with an August study — however podiatrists and orthopedists mentioned they’ve seen a big uptick in the variety of instances in the previous couple of years, particularly amongst folks 40 and older.
This improve troubles Dr. Priya Parthasarathy, a podiatrist in Silver Spring, Maryland.
“We’re seeing more and more of these because greater numbers of older people are demanding explosive-style workouts,” she mentioned. “With the Achilles, it’s all about gradual load. Anything else could be dangerous.”
The calcaneal tendon was named the Achilles in 1693 by Flemish anatomist Philip Verheyen as a reference to the mythological Greek hero, whose solely susceptible spot was his heel. It is the longest and strongest tendon in the physique. From a physiological perspective, it connects the calf muscle mass to the heel bone. Biomechanically, the tendon can stand up to forces as much as four times a person’s body weight.
The Mayo Clinic notes that the tendon is essential as a result of it permits for plantar flexion of our toes, the means to level toes downward. Plantar flexion makes it a necessary a part of our means to stroll, run and leap, in keeping with Dr. Michael Alaia, a professor in the division of orthopedic surgical procedure at New York University Grossman School of Medicine.
“You can’t really move around without engaging your Achilles,” he mentioned. “Anything where you start and stop rapidly, or even when you’re coming down from a jump, the Achilles will feel some stress.”
As a outcome, the tendon is in fixed use, which, in keeping with the Cleveland Clinic, means it could possibly naturally weaken over time.
Recent research signifies such degeneration generally is a large think about Achilles ruptures. As folks age, their tendons lose elasticity and develop into brittle, making a state of affairs through which the unsuitable transfer at the unsuitable time can result in disaster.
Men between the ages of 35 and 50 are significantly prone, Alaia famous.
Other situations make the Achilles extra vulnerable to rupture as nicely.
A 2024 study in the Journal of Sport and Health Science steered that the sure antibiotics in the fluoroquinolone class — reminiscent of ciprofloxacin — carry a “black box” warning from the US Food and Drug Administration for tendon issues, together with Achilles tendon rupture, particularly in older sufferers or those that take steroid medicines.
Add to the combine different components reminiscent of weight problems, poor conditioning and train overload on the a part of “weekend warriors” who work out arduous on Saturdays and Sundays, and the dangers of rupture multiply exponentially.
Unfortunately, particularly if you happen to’re in the 35- to 50-year-old demographic, there’s nothing you are able to do to forestall an Achilles tear.
Still, the greatest solution to keep away from one is to reduce the threat. According to Alaia, it is best to stretch earlier than exercise, take heed to your physique, enable for time to relaxation between exercises, hold your self hydrated, get good sleep and abstain from smoking cigarettes.
Parthasarathy added it’s additionally essential to spend money on good sneakers, steadily improve the depth of exercises and strengthen the muscle mass round the Achilles to alleviate a few of the load that the tendon sometimes carries. To strengthen these muscle mass, she recommends utilizing a steadiness board, or taking part in common yoga lessons.
“Anything you can do to slow down is going to put you at less of a risk,” Parthasarathy mentioned. “The very last thing you want to hear in a workout is that pop.”
Perhaps the commonest set off for an Achilles tear is the so-called explosive motion. On the basketball courtroom, it may very well be so simple as a sudden change in course. On pickleball or tennis courts, it might come up from transferring all of a sudden to return a smash.
Doctors agree that the most harmful movement for an Achilles is the step again.
Often, in keeping with Parthasarathy, this transfer places unbelievable strain on the Achilles in the leg that’s dropping again — strain that would snap the tendon if it is compromised in any means.
This motion is exactly what spelled doom for skilled hoopsters Lillard, Tatum and Haliburton this 12 months. NFL followers would possibly keep in mind that the step again is what felled quarterback Aaron Rodgers 4 snaps into his debut for the New York Jets in 2023.
It’s additionally what left Lazzaro collapsed on her health club ground.
Sometimes, nonetheless, different seemingly innocuous motions can set off a severe Achilles rupture.
In the spring, Kevin Mullins, 40, of Boston performed in an alumni lacrosse recreation in Maine. No greater than 10 minutes into the motion, the former Bowdoin College athlete was working down the area at about 50% velocity, and his Achilles gave out. One second, he was positive. A second later, he felt like somebody had shot a ball at his calf and he couldn’t transfer.
“It was the craziest thing because there was absolutely no pain,” Mullins mentioned. “I was aware that more people have been getting this injury. I just never thought it would happen to me.”
Doctors diagnose a torn Achilles with the assist of one thing referred to as the Thompson Test. Patients lie face down with their toes dangling over the fringe of the examination desk. Doctors then squeeze the calf muscle of the injured leg.
In wholesome legs — these with an intact Achilles — a squeeze of the calf will set off plantar flexion, and the toes will level downward. In legs with a ruptured Achilles, a squeeze of the calf will do nothing.
“The Thompson Test makes it pretty obvious” that somebody has ruptured their Achilles, Alaia mentioned, noting that some medical doctors will use an ultrasound machine or get an MRI earlier than an official prognosis.
There are two principal therapies as soon as a rupture has been confirmed: surgical and nonsurgical intervention. To decide which choice to suggest, medical doctors sometimes will take into account whether or not the tear is full or partial, and what kind of health stage the affected person seeks to regain as soon as the harm has healed.
Frequently, surgical procedure is obtainable to restore full tears in sufferers who want to return to aggressive sports activities. A 2024 meta-analysis in the journal Frontiers in Surgery indicated that the advantages of surgical procedure are easy: Repaired tendons are stronger, they rerupture much less incessantly, they usually enable for a faster return to sports activities. However, a 2023 study in the Canadian Journal of Surgery steered that nonsurgical choices can have encouraging outcomes, too, regardless of an extended highway to restoration and a barely greater rerupture fee.
However a affected person decides to deal with an Achilles rupture, two issues are sure: no driving for at the least a month after the harm (extra time if it’s the proper Achilles) and many rehab.
Most sufferers begin their restoration in a solid to immobilize the tendon and provides it time to heal. Past protocols required immobilization for months; research means that the introduction of sunshine weight-bearing exercise round the third week after harm can sluggish the improvement of scar tissue and speed up the therapeutic course of.
Rehab philosophies differ broadly from there.
Most medical doctors prescribe a number of weeks in a strolling boot, adopted by sluggish and regular bodily remedy that begins with mild stretches and ultimately strikes into restriction-free, weight-bearing train.
Others, reminiscent of Dr. Chris Smith, a health care provider of bodily remedy in West Islip, New York, take a extra aggressive strategy.
Frustrated by the strategies of most rehab applications, Smith launched the Achilles Rebuild, a program that goals to get folks snug and assured with getting again to train as quickly as doable. Smith works with shoppers nearly; he has weekly consultations with them and sends them lists of workouts to do.
“The traditional approach to rehab is protocol-based — they’re making decisions based on a timeline they have for everyone,” he mentioned. “The truth is that every person recovers differently. Building a program around performance metrics is much more sensible.”
