Achilles Tendon Repair

Achilles tendon repair is a surgical procedure that sews a torn Achilles tendon back together, so the calf muscles regain their pull on the heel bone. It is most often done for a complete rupture, takes about 60 minutes, and usually lets you go home the same day. The tendon then needs roughly 20 weeks of guided rehabilitation to regain its full strength.

What is Achilles tendon repair?

The Achilles is the thickest tendon in the body. It joins the two calf muscles, the gastrocnemius and the soleus, to the calcaneus, the heel bone. Every step, jump and tiptoe rise runs through this cord. When it tears completely, the foot loses most of its push-off power. The condition is described on our Achilles tendon rupture page.

Achilles tendon repair is a foot and ankle operation, covered more broadly in our foot and ankle section. The surgeon exposes the torn ends, trims the frayed tissue and joins them with strong, non-dissolving sutures. The aim is to restore the right length and tension. A tendon healed too long is weak, while one healed too short limits ankle flexion. Getting that tension correct is the heart of the operation.

What problems does Achilles tendon surgery treat?

Achilles tendon surgery is mainly used for an acute full-thickness rupture, where the tendon has snapped, often about 4 to 6 cm above the heel in the poorly supplied "watershed" zone. It is also used for tears at the heel insertion, for neglected ruptures that were missed for weeks, and for large chronic tears with degenerated tendon that need a tendon transfer or graft.

It is not usually the answer for a sore, thickened tendon without a tear. Tendinopathy, where the tendon is irritated but intact, responds to loading exercises, shock-wave therapy and activity changes far more often than to an operation.

How does Achilles tendon repair work?

Tendon heals by forming scar-like collagen between the torn ends. Left apart, the gap fills with stretchy tissue and the tendon lengthens. Surgery holds the ends close together while that collagen matures, which usually takes many weeks. Controlled loading afterwards helps the new fibres line up along the direction of pull, so the tendon grows stronger rather than stiff.

That is why the rehabilitation plan matters as much as the operation. A well-sewn tendon still needs months of protected, progressive loading before it can handle a sprint or a jump safely.

Who gets a ruptured Achilles?

Ruptures are most common in people aged about 30 to 50 who play sport only occasionally, such as football, badminton, tennis and basketball. Men are affected more often than women. The tendon often fails during a sudden push-off or an unexpected stumble, and many people report feeling or hearing a pop, as though they had been kicked in the back of the leg.

Certain medicines carry a known association with tendon injury, especially fluoroquinolone antibiotics and repeated steroid injections near the tendon. Tell your surgeon about any such treatment, because it may change both the surgical plan and the healing outlook.

Is Achilles tendon repair major surgery?

The operation is considered moderate rather than major. The incision is small, there are no implants left in the bone in most cases, and blood loss is minimal. However, the recovery is long compared with the surgery itself, because the tendon needs months to rebuild. The leg is weak for a considerable time even after the wound has healed.

How does Achilles tendon repair compare with non-operative care?

Both approaches can work. Modern functional rehabilitation, with an early-motion boot, gives good results for many people without an operation. Surgery usually offers a lower chance of a second rupture and a slightly quicker return of push-off strength, at the cost of wound risks and nerve irritation. Neither route is right for everyone, and the choice is made with your surgeon after an ultrasound or MRI.

Who should think twice before surgery?

People with poor skin over the heel, uncontrolled diabetes, severe vascular disease, or active infection carry higher wound risk and may do better with non-operative care. Smokers also heal more slowly. A low-demand patient with other serious medical conditions may reasonably choose a boot rather than an anaesthetic. Your surgeon will discuss these trade-offs honestly before you decide.

Good preparation for Achilles tendon repair starts the moment the injury happens: protect the leg, avoid walking on it, and see a clinician quickly. Most of the planning that follows is about confirming the diagnosis, checking you are fit for anaesthesia, setting up your home for a few weeks on crutches, and arranging time away from work and driving.

What should I do straight after the injury?

A suspected rupture needs urgent local care. Go to an emergency department or urgent orthopedic clinic, keep the foot in a pointed-toe position in a splint or boot with heel wedges, avoid weight-bearing and do not stretch the calf. Treatment abroad is only suitable for stable patients, once the diagnosis is confirmed and the leg has been protected. Never delay local care to arrange travel.

Which tests and scans are used?

Diagnosis is mostly clinical. The surgeon checks the gap, the Thompson squeeze test and the resting position of the foot. Ultrasound shows the gap and whether it closes in plantar flexion. MRI adds detail for partial, chronic or insertional tears. Blood tests, an ECG and a chest assessment may be requested for older patients or those with other conditions.

How do I prepare my health before Achilles tendon surgery?

Stopping smoking at least 4 weeks beforehand improves wound healing. Diabetes should be well controlled, and your doctor should review blood thinners, anti-inflammatories and fluoroquinolone antibiotics. Do not stop prescribed medicine without advice. Report skin infections, ulcers, or a recent steroid injection near the tendon, as these can change timing or technique.

• Bring a list of all medicines, supplements and allergies.
• Bring previous scans, reports and the splint or boot you were given.
• Share any history of blood clots, because a leg in a boot has a higher clot risk.
• Ask about the anaesthetic type and the nerve block, and what you may eat beforehand.

What should I send for a remote review?

A remote review can happen before you travel. Send the ultrasound or MRI report with images if possible, the date and circumstances of the injury, a list of medicines, photographs of the heel and calf, and your general health summary. Our guide to medical record review explains what specialists look for, and the treatment planning guide describes the next steps.

How do I set up my home and work?

Plan for at least 2 weeks of mostly sitting with the leg raised, then crutches for several more. Put essentials at waist height, arrange a seat for the shower, clear rugs and cables, and plan help with shopping and lifts. Desk work may be possible within 1 to 2 weeks, but standing or manual jobs often need 8 to 12 weeks off or adapted duties.

Driving needs particular thought. A right-sided repair usually rules out driving for about 6 to 8 weeks, until you can brake safely and out of the boot. Left-sided repair in an automatic car may allow earlier return. Check the insurance position as well as your own comfort.

What should I practise before the day?

Learn to use crutches or a knee scooter while you are still fit, and practise stairs. Strengthening the other leg, the hips and the core before surgery pays off during weeks of non-weight-bearing. If your injury allows, ask the physiotherapist to show you the first exercises you will use after the operation, so they feel familiar when you start them.

In Achilles tendon repair the surgeon exposes the ruptured ends, passes strong sutures through both ends to bring them together under the right tension, and closes the skin carefully. The operation usually takes about 60 minutes, with the tourniquet and anaesthetic time adding to your theatre stay. Several techniques exist, and the choice depends on the tear and the surgeon's training.

How is anaesthesia given?

Most repairs are done under general anaesthesia, a spinal anaesthetic, or a regional block of the sciatic and saphenous nerves, sometimes combined with sedation. A nerve block can reduce pain for many hours afterwards. The anaesthetist will explain which suits you, taking into account your health, your preferences and any history of nausea or breathing problems.

How are you positioned?

For the open approach you lie face down, with the ankle supported on a pad so the foot hangs slightly. Some surgeons use a side-lying or supine position, especially for minimally invasive methods. A thigh tourniquet may be used to give a clear field. The leg is cleaned, draped, and a dose of antibiotic is given before the first cut.

What are the key steps of an open Achilles tendon repair?

1. A vertical incision of about 6 to 10 cm is made slightly to the inner side of the tendon, away from the sural nerve.
2. The thin outer sheath, the paratenon, is opened and kept, so it can be closed later to protect blood supply and reduce adhesions.
3. The frayed ends are cleaned, and the tendon is sewn with a locking suture pattern such as a Krackow or Bunnell stitch.
4. With the ankle held in gentle plantar flexion, the sutures are tied so the ends meet without a gap and without excess tension.
5. The surgeon tests tension by comparing resting foot position with the other side and by squeezing the calf.
6. The paratenon, subcutaneous layer and skin are closed in layers, and a bulky dressing and splint or boot are applied.

What is minimally invasive Achilles tendon repair?

Minimally invasive Achilles tendon repair uses small stab wounds or a short incision of around 2 to 3 cm, with special guides to pass sutures through the tendon. Because the skin is opened less, wound complications are less common than with long open cuts, and scars are smaller. The trade-off is a higher chance of irritating the sural nerve, which runs close to the tendon, plus less ability to inspect the ends.

Which technique do surgeons choose?

What happens if the gap is large?

A tendon left untreated for weeks retracts, and the ends cannot be pulled together. Surgeons then lengthen the tendon with a V-Y advancement or a turndown flap from the calf-side tendon, or transfer the flexor hallucis longus tendon from beside the big toe, which has its own blood supply and a similar line of pull. These operations take longer and need a slower rehabilitation.

How long does Achilles tendon repair take?

Most procedures run about 60 minutes of surgical time, with more for reconstructions that include a transfer or a heel bone procedure. In total you can expect around 2 to 3 hours from entering the anaesthetic room to arriving in recovery, including preparation, drapes and awakening, and a few more hours before you go home.

How does this differ from other ankle operations?

Unlike ankle arthroscopy, which works inside the joint through keyhole portals, a tendon repair works on the soft tissue behind the ankle. Fusion and replacement, such as total ankle replacement, deal with worn cartilage and need implants, which a standard tendon repair does not.

What happens at the end of the operation?

Once the skin is closed, a padded splint holds the foot gently pointed downward, or you are placed in a boot with several heel wedges. Pointing the toes slackens the repair, so the tendon is not stretched. You then wake up in recovery, where staff check pain, nausea, circulation to the toes and nerve block recovery before you go to the ward.

Most people go home the same day after Achilles tendon repair, so the typical plan is 0 hospital nights. A short admission of 1 night is arranged when pain control, other illness, home support or transport make a same-day discharge unsafe. The aim of the stay is safe pain control, a protected leg and confidence with crutches.

What happens on the day of surgery?

You arrive fasting, change into a gown, meet the surgeon and anaesthetist, and the operative leg is marked. After surgery you are taken to recovery, then back to the ward. A nurse checks the toes for colour and warmth, the dressing for bleeding, and your pain score. Light food and a drink are given once you are awake.

How is pain controlled?

Pain control is multimodal: a nerve block, regular paracetamol, an anti-inflammatory unless unsuitable, and a short supply of stronger opioid medicine for breakthrough pain. The block can wear off during the first night, and pain may rise sharply then, so take the first dose of oral painkiller before it fades. Keeping the leg raised above heart level is as helpful as any tablet.

When can I leave and what are the discharge criteria?

Typical criteria are: pain manageable with tablets, no heavy bleeding, warm pink toes, safe movement with crutches, a plan for stairs, and a responsible adult at home overnight. The physiotherapist teaches non-weight-bearing walking before discharge. You also leave with your boot or splint instructions, wound advice, and a written plan for the first follow-up.

How do I look after the wound and boot?

Keep the dressing clean and dry until your first review at about 10 to 14 days. Do not remove the splint or boot unless told to. Cover it with a waterproof bag to wash, or use a seated sponge bath. Wiggle the toes often, elevate the leg, and contact the team if the dressing becomes soaked, smelly, or the toes turn blue or numb.

Which blood clot precautions are used?

A leg in a boot and a lower level of activity raise the risk of a deep vein thrombosis. Depending on your risk factors, your surgeon may advise a blood-thinning injection or tablet for a few weeks. Move the other leg and hips, stay hydrated, and report calf swelling beyond the usual, chest pain or breathlessness urgently.

What should international patients know?

Planned Achilles tendon repair in turkey is realistic for a stable patient whose diagnosis is confirmed and whose leg has been protected locally. Travel is usually timed between about 1 and 3 weeks after injury. Plan 7 to 10 days nearby for the first review and wound check, bring your boot, and read our guides on travel and accommodation, hospital admission and flying after surgery.

Because a boot and recent surgery raise clot risk on long journeys, ask the surgeon about the safest flight date, aisle seating, and whether blood thinners are advised. A companion helps with luggage and stairs, and our companion guide explains how to share the load.

Recovery from Achilles tendon repair is gradual: expect about 2 weeks of protection, a boot-based loading phase until 6 to 8 weeks, strengthening to 4 months, and a return to sport at around 6 to 12 months. The Achilles tendon repair recovery time of about 20 weeks is the point at which most people walk and work normally, though power keeps building for a year.

What does the first 2 weeks feel like?

The first days are about rest, elevation and pain control. The calf and foot swell, and bruising often tracks down toward the toes. Most people are not allowed to put weight through the heel yet, so crutches carry the load. Pain usually peaks in the first 2 or 3 days, then eases. Sleeping with the leg raised on pillows helps considerably.

What is early functional rehabilitation?

Many surgeons now use "early functional rehabilitation" rather than strict plaster. In this approach you wear a hinged or wedge boot soon after surgery and begin gentle ankle movement within the first weeks. Evidence from trials suggests that early motion and loading can speed return without raising the chance of a second rupture when the repair is secure and the plan is followed carefully.

How do the boot wedges work?

The boot has removable heel wedges that hold the foot pointed downward at first. Every 2 weeks or so, one wedge is removed, so the ankle comes gradually toward neutral. Weight-bearing increases in step. Do not skip ahead, and do not take the boot off for comfort, because sudden stretch is the commonest way to stress a young repair.

When does physiotherapy start?

Gentle range of motion usually begins at 2 weeks. From about 6 to 8 weeks, you move into a normal shoe and start light calf work: seated heel raises, then double-leg heel raises, balance training and stationary cycling. Single-leg heel raises are typically added around 3 to 4 months. Physiotherapy continues for several months and should be paced by strength rather than the calendar.

When can I drive, work and fly?

• Driving: about 6 to 8 weeks for a right-sided repair, and sooner for an automatic car and left leg, once you can brake firmly without pain.
• Desk work: often 1 to 2 weeks with the leg raised and breaks to move.
• Standing or manual work: around 8 to 12 weeks, with graded duties.
• Flying: usually allowed after the first review, with clot precautions.

When can I return to sport?

Light jogging often starts at about 4 to 6 months if calf strength on the repaired side is close to the other leg and hopping is comfortable. Jumping and cutting sports usually wait until 6 to 9 months, and some people need up to 12 months before the leg feels fully trusted. Strength testing is a better guide than time alone.

What does normal healing look like?

Which symptoms are red flags?

Contact your surgeon or emergency department if the wound opens, leaks pus or smells, redness spreads, you develop a fever, the calf becomes hot and tender, or the leg suddenly feels weak with a new pop. Chest pain or breathlessness needs emergency care. A sudden sharp event while stepping, with loss of push-off, may be a re-rupture and should be assessed quickly.

Why is the calf thinner after surgery?

Muscle shrinks during weeks of reduced use, and some of that loss is permanent in terms of volume, though strength can return. A mildly thickened tendon and a small scar bump are also normal. Targeted calf strengthening, adequate protein intake and patience usually rebuild what can be rebuilt. Look for gradual gains month by month rather than week by week.

Our guides on rehabilitation and follow-up after returning home describe how to keep your physiotherapy going once you are back in your own country.

Most people do well after Achilles tendon repair, walking normally, working and returning to recreation within about 6 to 12 months. Success means a strong, properly tensioned tendon, no second tear and a comfortable heel. Some loss of peak calf power compared with the other side is common, and it matters mainly to high-level athletes.

What is the Achilles tendon repair success rate?

The Achilles tendon repair success rate is high when success means healing without re-rupture and returning to normal activity. Large reviews suggest that re-rupture after surgery is uncommon, often cited at roughly 2 to 5 in 100, and that most people return to their earlier level of activity. Exact numbers vary by study, technique, rehabilitation and patient group, so treat them as a rough guide.

How does repair compare in the long term with a boot alone?

Randomised studies using early-motion boots have found that function at 1 year is similar between surgery and non-operative care in many patients. Surgery tends to carry a lower chance of re-rupture, while a boot avoids wound and nerve complications. These findings are why surgeons talk through both paths, rather than recommending an operation automatically.

What factors improve the result?

• Surgery within a few weeks of the injury, before the tendon retracts.
• Correct tension at repair and secure sutures.
• Following the boot, wedge and loading plan without shortcuts.
• Not smoking and good control of diabetes and weight.
• Strengthening that continues well beyond the point when walking feels normal.

What factors worsen the result?

A delayed repair, an overloaded early recovery, smoking, a wound infection, a tendon that was degenerated before it tore, and long-term steroid or fluoroquinolone use can all reduce results. Returning to sprinting or jumping too early is a particular risk. Poor rehabilitation is often the key factor that separates a good result from a disappointing one.

Will my calf be as strong as before?

Many people regain good strength, but the repaired side often stays a little weaker than the other side, especially for power and endurance on tiptoe. Tests commonly show a small residual deficit that most people do not notice in daily life. A long, structured strengthening programme and repeated testing give the best chance of closing the gap.

How long does the repair last?

A healed repair is generally durable, and many patients never need further treatment on that tendon. The other Achilles remains at risk, however, because the same degenerative changes are often present on both sides. Keeping calf strength high, warming up before sport and reviewing any tendon pain early lower the chance of a later injury.

When is revision needed?

Revision is uncommon. It may be needed after a re-rupture, a deep infection, or a repair that healed too long and left the calf weak. These cases are more complex and may use a tendon transfer or graft. An early opinion if strength seems to be falling behind is more useful than waiting and hoping it will catch up.

How satisfied are patients?

Satisfaction is generally good in studies, particularly when expectations were set clearly beforehand. The most common frustrations are the long recovery, the thin calf, and a scar that stays tender for months. People who know what the timeline looks like in advance tend to cope better with the slow middle stretch of rehabilitation.

Achilles tendon repair relies on strong sutures, simple guide instruments, and sometimes bone anchors, rather than on large implants. Surgeons use non-absorbable or very slow-absorbing braided sutures, specialised needles and, in minimally invasive methods, guides that pass sutures safely. Imaging helps with diagnosis, and rehabilitation devices such as adjustable boots are a form of technology in their own right.

Which sutures and stitch patterns are used?

High-strength braided sutures, often coated polyester or composite with ultra-high-molecular-weight fibres, hold the tendon while it heals. Locking patterns such as the Krackow, Bunnell and Kessler designs grip the tendon along its length, so the stitch resists pulling out. Surgeons often add a fine running stitch around the repair line, which helps smooth the surface and adds strength.

When are bone anchors used?

For tears at the heel insertion, the tendon is fixed back to the calcaneus with one or more suture anchors, small screws or implants that hold sutures in bone. A double-row arrangement spreads the load across a wider area, and the same anchors are used in other tendon-to-bone repairs. The implants stay in place permanently, and they are usually not felt once healed.

What tools support minimally invasive repair?

Specialised percutaneous guides, such as jig systems with grooves for the needles, allow suture passes through tiny skin cuts, while keeping a safe distance from the sural nerve. Some surgeons check the repair with a small mini-open window or with ultrasound. These devices make smaller scars possible, but they require training and are not suited to every rupture.

Are grafts and augmentation options available?

For chronic or large gaps, surgeons may use local tissue, such as a turndown flap, or a transferred tendon like flexor hallucis longus. Synthetic and biological patches exist, though evidence for them is limited and they are used selectively. Platelet-rich plasma has been studied for tendon healing but trials have not shown a consistent benefit, so it is not a routine part of care.

How does imaging help?

Ultrasound is fast, inexpensive and dynamic, and it can show how the ends move as the foot is flexed. MRI shows tendon quality, partial tears and associated heel changes. Neither replaces a careful examination, but both help decide between surgery and a boot. Some surgeons repeat an ultrasound later to follow tendon healing and thickness.

What about rehabilitation technology?

Adjustable hinged boots with removable wedges, insoles that measure weight-bearing, and gradual-loading devices help keep progress safe. Some clinics use blood-flow restriction training to maintain calf strength with lighter loads. Such tools can support a good plan, but none replaces regular review and consistent exercise.
