Achilles Tendinopathy in Older Adults: A Physical Therapy Recovery Protocol

The first few steps after getting out of a chair feel stiff and tight, right at the back of the ankle. It loosens up after a minute of walking, then it is back the next morning, a little worse after a long day in the garden.

A lot of people over 60 dismiss this with the same sentence: “But I don’t even run.”

That sentence is the most useful clue in the whole picture. An older Achilles tendon usually becomes painful for different reasons than a runner’s does, and most of the exercise advice online was written for the runner.

If you are a senior with a sore, stiff Achilles, this guide explains what is changing inside the tendon and how a physical therapist rebuilds it. If you are a caregiver whose parent has started taking the stairs one at a time, or who heard a pop and kept walking anyway, this is written for you too.

Quick Answer: What Is Achilles Tendinopathy, and How Long Does Recovery Take?

Achilles tendinopathy is pain and stiffness in the tendon that joins your calf muscles to your heel bone. In older adults it is driven mostly by slow breakdown inside the tendon, which Cleveland Clinic calls tendinosis and describes as a degeneration that does not cause swelling, redness or heat.

The first-line treatment is exercise that loads the tendon, not rest. Many people notice real improvement by about 12 weeks, though full recovery can take a year or longer.

A torn (ruptured) Achilles is a different injury with a longer road. The American Academy of Orthopaedic Surgeons (AAOS) says complete recovery takes about 12 months, and some patients report it takes closer to 2 years.

Why an Older Achilles Is a Different Problem From a Runner’s

The best-known Achilles exercise program was built on 15 recreational athletes with an average age of 44. Every one of them got back to running, and that study became the template for nearly every heel-drop routine you will find online.

Older tendons start from a different place.

In 2013, Danish researchers used carbon left in the atmosphere by 1950s nuclear tests to date the tissue inside human Achilles tendons. The core of the tendon matched the first 17 years of life, meaning it is essentially not renewed once you stop growing.

Muscle, by contrast, rebuilds itself continuously. By 70, the center of your Achilles has been carrying you around on the same material for more than half a century.

That tissue collects changes over time. A study of 891 people whose tendons ruptured without a major injury found that not one ruptured tendon was structurally healthy, and 97% of the abnormal changes were degenerative.

The authors concluded that degenerative changes are common in the tendons of people over 35 and are linked to spontaneous rupture.

It is not only an athlete’s problem, either. In a Dutch study of nearly 58,000 primary care patients, a link to sports was recorded in just 35% of Achilles tendinopathy cases.

In clinics, the pattern usually seen in older adults is rarely a tendon that was overworked by training. It is more often a tendon that has done less and less for years, then met a new walking routine or a vacation full of stairs.

Where It Hurts Decides Which Exercises Are Safe

There are two main types of Achilles tendinopathy, and the difference decides which exercises belong in your program.

• Midportion (noninsertional): Pain and thickening in the middle of the cord, above where it attaches to the heel. AAOS notes this type is more common in younger, active people, especially runners.
• Insertional: Pain right where the tendon attaches to the back of the heel bone, often with a bone spur. AAOS says this type can occur at any activity level.

The step heel drop, the exercise at the top of most Achilles search results, is only for the midportion type. AAOS is direct about it: do not perform these exercises if you have insertional Achilles tendinitis.

Insertional pain gets a modified version done on flat ground, so the heel never sinks below the level of the toes.

Everyday Signs of Achilles Tendinopathy

• Stiffness and pain at the back of the ankle with the first steps in the morning or after sitting for a while
• Pain that eases once you get moving, then returns later in the day or the next morning
• A thickened, tender spot on the cord that hurts when pressed
• A burning ache during activity rather than a sharp stab
• Rising onto your toes on that leg feels weak or sore compared with the other side
• No redness or warmth over the tendon, even on a painful day

Pain under the heel is a different problem. If the worst spot is on the bottom of the heel and sharpest with the first step of the morning, the guide to plantar fasciitis in seniors is the better place to start.

Plantar fasciitis hurts under the heel. Achilles tendinopathy hurts behind it.

Two Medications That Change the Picture

Some Achilles problems in older adults have a trigger most people never connect to their leg: a recent antibiotic.

Fluoroquinolone antibiotics, including ciprofloxacin and levofloxacin, carry an FDA boxed warning for tendinitis and tendon rupture. The prescribing label says the risk is higher in people over 60, in people taking corticosteroids such as prednisone, and in people with kidney, heart or lung transplants.

The label also notes that this reaction most often involves the Achilles, and that it can appear within hours of starting the drug or as long as several months after finishing it.

If you notice new Achilles pain while taking one of these antibiotics, or in the months after, call the prescriber the same day. Do not stop a prescribed medication on your own; the label itself tells patients to rest and contact their provider about switching to a different antibiotic.

The second medication is cortisone. AAOS advises against cortisone injections into the Achilles tendon because they can cause it to rupture.

If you are a caregiver who helps manage medications, a recent antibiotic is worth writing on the list you bring to the appointment, even if the course ended weeks ago.

The Recovery Protocol: Achilles Tendon Exercises in Stages

The 2024 physical therapy guideline for midportion Achilles tendinopathy gives its top grade to one recommendation: tendon loading exercise, with loads as high as tolerated, as a first-line treatment. It also advises that complete rest is not indicated.

The stages below show how that is usually adapted for an older adult. Keep one hand on a counter or a sturdy chair for every standing exercise, since each one puts you up on your toes.

• Stage 1, if a heel raise is not possible yet: Sit with the foot flat and press the ball of the foot into the floor without moving, or push against a resistance band. A clinical review from the researchers behind the pain-monitoring approach suggests exactly these options when a heel raise is too much.
• Stage 2, seated heel raises: Sitting in a firm chair, lift both heels slowly and lower them slowly. The same review starts at 3 sets of 10 and builds to 3 sets of 15.
• Stage 3, standing heel raises on both feet: Holding the counter, rise up slowly and lower yourself even more slowly. Work toward 3 sets of 15 before moving on.
• Stage 4a, midportion pain only, the step heel drop: Stand with the front half of both feet on a stable step, rise up, then slowly lower your heels below the level of the step. AAOS lists 20 repetitions.
• Stage 4b, insertional pain, the floor-level version: Do the same slow lowering on flat ground, so the heel stops at the floor. In a Swedish pilot study of 27 patients with an average age of 53, two-thirds were satisfied at 4 months after 3 sets of 15, twice a day, for 12 weeks.
• Stage 5, one leg, then added weight: Progress to heel raises on the sore leg alone, then add a light backpack. The review’s rebuilding phase uses 3 sets of 15 on one leg with added weight.

Heavier, slower strength work is a valid alternative to heel drops. A Danish trial of 58 patients found heavy slow resistance training as effective as heel drops at one year, and people stuck with it more often: 92% versus 78%.

That adherence number matters for older adults. The 2024 guideline recommends at least 3 sessions a week and notes that frequency, from once a day to 3 times a week, did not seem to change outcomes.

Calf stretching plays a supporting role, not the main one. The guideline allows it with the knee straight and with it bent, and AAOS describes a wall stretch held for 30 seconds, repeated 10 times on each side.

If a resistance band is the only comfortable place to start, these ankle strengthening exercises with a therapy band show how to set one up safely.

How Much Pain Is Acceptable During Achilles Exercises

This question decides whether a program works.

Too little load does nothing, and too much flares the tendon.

A Swedish trial let one group keep up their usual activity while monitoring pain, and made the other group rest for 6 weeks. At 12 months both groups had improved by similar amounts, and continuing to move did no measurable harm.

The practical rule from that research group is simple: some discomfort is acceptable, but avoid moderate or severe pain and symptoms that worsen over time.

The easiest way I know to apply that is a morning check. If the tendon is stiffer or sorer the next morning than it was the morning before, the last session was too much; drop back a stage for a few days rather than stopping.

What the Research Does Not Tell Us About Older Adults

Here is the part most exercise pages skip.

When researchers tried the classic heel-drop program on 34 sedentary patients, some as old as 76, it helped nearly 60%. About 44% did not improve, and 7 went on to surgery after 6 months of conservative care.

The authors put it plainly: eccentric exercises may not benefit sedentary patients to the same extent reported in athletes.

The 2024 guideline flags the same gap in its own evidence. It states that generalization is limited for people who have a low level of physical activity, and its exercise recommendation applies to people without presumed frailty of the tendon.

The broader evidence is thin too. A 2021 analysis of 29 trials found none at low risk of bias.

Every active treatment in that analysis beat wait-and-see at 3 months, and none was clearly better than the others. The authors suggested starting with a calf exercise program because it is low cost and has few harms.

None of this is a reason to skip exercise. It is a reason to expect a slower curve and to have someone adjust the plan when progress stalls.

There is good news in the physiology as well. In a small study of nine adults averaging 74 years old, 14 weeks of strength training made the knee’s patellar tendon 65% stiffer, which the authors linked to better force transmission.

The core of the tendon may be decades old, but tendons still respond to load in your 70s.

If the Achilles Tears: Recovery Time for a Torn Achilles Tendon

A degenerated tendon is the kind that ruptures, and ruptures after 50 are becoming more common. A Danish registry of 33,160 ruptures found a significant rise in incidence among people over 50 across 20 years.

The classic sign is a pop or snap at the back of the ankle, followed by pain and trouble rising onto your toes on that leg.

Here is the trap.

Many people with a complete tear can still walk and can still point the foot a little, because other tendons running from the calf to the foot take over part of the job.

That is how a rupture gets written off as a sprain. A clinician can check in seconds with a calf squeeze test, which picked up 96% of confirmed ruptures in a study of 174 patients.

Get it seen the same day.

A review written for family doctors notes that a delay in diagnosis of more than 24 hours is a relative indication for surgery.

Treatment is either a boot or cast with the toes pointed down for at least 6 weeks, or surgery followed by rehab. AAOS notes that complete tears in less active people often respond well without surgery.

The largest recent trial, published in 2022, randomized 554 adults to non-surgical care, open surgery, or minimally invasive surgery. At 12 months their scores were the same; re-rupture was more common without surgery (6.2% versus 0.6%), while nerve injuries were more common with it.

The catch for this audience is that the trial only enrolled adults aged 18 to 60, with an average age of 40. Nobody over 60 was studied, so for an older adult the choice rests on overall health and how active you plan to be, decided with the surgeon.

A 2019 analysis of 15,862 patients found the same trade-off. Surgery lowered re-rupture from 3.9% to 2.3% but raised other complications from 1.6% to 4.9%, and with early-motion rehab the re-rupture gap was no longer significant.

As for recovery time itself, the major sources disagree, and the disagreement is useful.

Cleveland Clinic says full healing of a torn Achilles typically takes about 4 to 6 months. AAOS says complete recovery takes about 12 months, and some patients report it takes closer to 2 years.

Both can be true.

The first number describes the tendon healing, and the second describes getting back to full function, which means rebuilding the calf strength that pushes you up stairs.

AAOS notes you will need crutches or a wheelchair to get around at first. If crutches feel unsteady, ask about a walker; this guide to choosing between a cane and a walker covers the options.

What a Physical Therapist Will Typically Check

The first visit mostly answers two questions: which part of the tendon is involved, and whether it is still intact.

• Exactly where it hurts, in the middle of the cord or at the heel bone, since that decides whether step heel drops are on the table
• The painful arc sign and the Royal London Hospital test, two quick hands-on checks the 2024 guideline lists for midportion pain
• A calf squeeze test to confirm the tendon is still connected
• How many single-leg heel raises you can do on each side, which gives you a number to beat at later visits
• How far the ankle bends upward with the knee straight and again with it bent
• Your full medication list, including any antibiotic or steroid from the past few months
• The shoes you wear most and how you walk in them

If you are a caregiver, the most useful thing to bring is timing. When did it start, and did anything change around then, like a new walking routine or a course of antibiotics?

What NOT to Do

• Do not rest the leg completely for weeks. The 2024 guideline advises against complete rest, and a tendon that is not loaded does not get stronger.
• Do not do step heel drops if your pain is right at the back of the heel bone. Use the floor-level version instead.
• Do not agree to a cortisone injection into the Achilles tendon without asking about rupture risk. AAOS advises against these injections.
• Do not stop a prescribed antibiotic on your own if your tendon starts to hurt. Call the prescriber the same day.
• Do not do any standing heel exercise without a hand on a counter or a sturdy chair.
• Do not walk off a pop at the back of the ankle, even if you can still walk. Get it checked that day.
• Do not judge progress by one bad day. Watch the trend across mornings over a couple of weeks.

Caregivers help most by making the program easy to do rather than by reminding. Set the sturdy chair next to the counter where the heel raises happen, and keep the exercise sheet where the morning coffee gets made.

Frequently Asked Questions

How long does Achilles tendinopathy take to heal in older adults?

Many people notice meaningful improvement by about 12 weeks of consistent loading exercise, but full recovery can take a year or more. Adults who were less active before the pain started may improve more slowly, which is a reason to adjust the program rather than abandon it.

My mother heard a pop in her heel but she can still walk. Does she need to be seen?

Yes, the same day. Walking is still possible with a complete Achilles tear because other calf tendons take over part of the job, and a quick calf squeeze test tells a clinician whether the tendon is intact.

Should I have surgery for a torn Achilles at 70?

There is no single right answer, and the biggest recent trial did not include anyone over 60. AAOS notes that complete tears in less active people often respond well without surgery, so the decision comes down to your health and goals, talked through frankly with the surgeon.

Will a night splint help my morning stiffness?

The experts disagree. AAOS says night splinting can provide significant relief for morning pain, while the 2024 physical therapy guideline advises against using night splints to improve symptoms, so ask your therapist before buying one.

Final Thoughts for Adults Over 50

An aching Achilles after 60 is not a runner’s injury that happened to the wrong person. It is an aging tendon asking to be loaded again, gradually and on purpose.

If you are a senior, start at the stage you can do without a flare, and judge progress by your mornings over weeks. Give it the full 12 weeks before deciding whether it is working.

If you are a caregiver, listen for two things: a recent antibiotic, and a pop.

The first changes how carefully the tendon should be loaded. The second means someone should look at it today.

Medical Disclaimer

This article is for general education and is not a substitute for medical advice. Talk with a doctor or physical therapist before starting any new exercise program for Achilles pain.

Seek same-day care for a pop or sudden weakness at the back of the ankle, or for new tendon pain while taking a fluoroquinolone antibiotic. Never stop a prescribed medication without first talking to the prescriber.
