Achilles Tendon Rupture and the Long Road Back to Basketball

At a glance

• An Achilles rupture usually feels like a pop, or a kick to the back of the heel, often on a sudden push-off or step back
• NBA players who ruptured an Achilles between 2010 and 2025 missed an average of 9.25 months, and their minutes per game fell by about a fifth after returning
• Surgery lowers the re-rupture rate to 2.3% against 3.9% without it, but carries more complications, so the choice is made with a surgeon
• In one 2026 study, only 40.8% of repaired patients had calf strength within 10% of the other side, even though most rated their recovery near-perfect

Getting back to basketball after an Achilles tendon rupture usually takes the best part of a year, and the tendon healing is only the first half of it. The second half is rebuilding the calf: its strength, its speed, and the spring a player needs to jump and push off again. That's the part that decides whether an athlete comes back at the level they left. Most athletes do return, but many come back with a calf that tests weaker than they think. At True Sports, an Achilles rupture is one of the foot, ankle and heel injuries we treat, before and after surgery, through orthopedic physical therapy for sports injury and post-surgical rehab. Here's what the injury is, why it's hitting basketball players, how surgery compares with a boot, and what a year of rehab actually builds.

The pop at the back of the heel

The Achilles tendon joins the calf muscles to the heel bone and takes enormous force every time you push off. When it ruptures, most athletes describe a pop, or the feeling that someone kicked them in the back of the heel. Cleveland Clinic lists "feeling or hearing a pop in your calf" and "feeling like you got hit or kicked in the heel or calf" as the most common symptoms, and notes that some people don't feel pain when it happens.

In basketball it tends to happen on an ordinary movement: a first step, a push-off, a quick step back. Afterward, walking and especially stairs become difficult, and the athlete can't rise up onto the toes of that foot.

Why basketball keeps losing players to it

Basketball loads the Achilles with constant sprinting, cutting and jumping, and the pro game has seen a run of high-profile ruptures. A 2026 review of NBA ruptures from 2010 to 2025 called the 2024-2025 season a record high. The players it followed missed an average of 9.25 months, and after returning their minutes per game fell by 20.2% and their player efficiency rating by 21.9%.

Nobody has a settled explanation yet. Dr. Jamie Quinto, a basketball-focused physical therapist, was asked why there are so many Achilles ruptures in the NBA and offered a working theory on the True Sports Podcast:

I think volume load is increasing ... I think the athletes are just getting more athletic. And we're just putting so much on them.

Dr. Yoni Rosenblatt, who hosts the podcast, added that nobody has really figured it out. For an individual player, though, the question that matters is narrower: is this calf ready for the load basketball puts on it?

Surgery or a boot?

Both routes can work, and the choice belongs to the athlete and their surgeon. A 2019 meta-analysis in the BMJ pooled 29 studies and nearly 16,000 patients. Surgery lowered the re-rupture rate to 2.3%, against 3.9% without it. It also raised the complication rate, 4.9% against 1.6%, mostly from infection.

In the studies that used accelerated functional rehab with early range of motion, the review found no significant difference in re-rupture between the two routes. The authors concluded the decision should rest on the individual athlete and shared decision-making. Whichever way the tendon is treated, the rehab that follows decides the outcome on the court.

The first months: protecting the tendon, keeping the calf

Early rehab follows the surgeon's protocol for weight-bearing and ankle position, because the healing tendon can't yet take full load. Within those limits, the job is to keep as much of the calf and leg as possible:

• Gradual range of motion as the protocol allows, without stretching the tendon long
• Strength for everything above the ankle, so the hip and thigh don't fade while the foot is protected
• Calf work at light loads, where blood flow restriction training can build muscle without heavy weight
• Walking mechanics, so the athlete doesn't settle into a limp that outlasts the injury

As the tendon tolerates more, calf raises progress from two legs to one, then to added weight.

A year out and still building

At True Sports' Frederick clinic, Dr. Abby King, PT, DPT, worked with a basketball player a little over a year after an Achilles repair. He'd torn it on a simple step back during a game. By that point the tendon had healed, and the sessions were about the things basketball actually asks of it: speed, power, tendon stiffness, and more calf strength.

Tendon stiffness is the spring. A stiffer tendon stores and returns energy on every jump and push-off, and it has to be trained back with hops, bounds and fast calf work once the tendon can take it. Rehab finishes when the calf is strong enough, fast enough and springy enough for the sport the athlete is returning to.

The heel-rise test that decides it

The single-leg heel rise, rising onto the toes of one foot as many times and as high as possible, is the simplest honest measure of an Achilles recovery. It often tells a different story from how the athlete feels.

A 2026 study of 76 repaired patients in the Journal of Clinical Medicine found they rated their Achilles at a median of 97 out of 100, yet only 40.8% had heel-rise performance within 10% of the other side. How they felt didn't predict how their calf performed. Across a 2016 BJSM review of 6,506 patients, 80% returned to play, and the studies that measured return carefully reported lower rates than those that didn't.

So the markers for a return to basketball are measured: heel-rise repetitions and height within about 10% of the other side, single-leg hops and landings that hold up, and full-speed cutting and jumping without the tendon flaring the next day.

Protein and collagen through a long rehab

A rehab this long runs on steady nutrition. Protein at 1.6 to 2.2g per kilogram of body weight daily, spread across meals of 20 to 40g, limits calf muscle loss during the protected months and supports the strength work that follows. Collagen at 5 to 10g with vitamin C, about an hour before a loading session, is worth considering once the tendon is being loaded, since vitamin C is needed to form new collagen. Neither replaces the loading, which is what tells the tendon to rebuild.

Questions players ask after an Achilles rupture

Can you walk with a ruptured Achilles?Often, yes, which is why some ruptures are missed at first. Walking is usually painful and weak, stairs are hard, and the athlete can't rise onto the toes of that foot. A pop or a kicked feeling at the heel needs to be checked that day.

How long until I can play basketball again?Cleveland Clinic puts recovery at four to six months, and up to a year to return to sports safely. NBA players in the 2026 review missed an average of 9.25 months. Measured calf strength, not the calendar, decides the date.

Will I lose my jump?Not necessarily, but it has to be rebuilt. Calf strength and tendon stiffness are the parts most often left short, which is why hop and heel-rise testing continues well past the point of feeling normal.

Can it rupture again?It can. Re-rupture rates in the BMJ review were 2.3% after surgery and 3.9% without it. Finishing the strength and spring work before returning to full basketball is the best protection.

If you've just felt the pop

A pop at the back of the heel, a weak push-off, or trouble rising onto your toes needs a medical assessment the same day. Once the surgeon has set the plan, we build the rehab around measured calf strength, hop testing and the demands of your position. Book your evaluation.
