Achilles tendon rupture
Also called: ruptured achilles, torn achilles, achilles tear, snapped achilles, achilles tendon tear. Clinical name: Achilles tendon rupture (complete or partial tear of the Achilles tendon).
A suspected Achilles rupture needs same-day assessment. Most people spend about 6–9 weeks in a boot or cast, with or without surgery. Return to sport typically takes 4–12 months, and full recovery about a year.
What it actually is
The Achilles tendon is the thick cord at the back of the ankle that connects the calf muscles to the heel bone, and a rupture is a tear through it, usually all the way. AAOS explains that it typically goes when a strong force stretches the calf too quickly, such as landing from a jump or a sudden cutting movement, and in football from being stepped on at the heel. Cleveland Clinic notes it is more common in sports with sudden stops, pivots and changes of direction (racket sports, football, basketball), in people aged 30 to 40, and in people taking steroids or certain antibiotics such as ciprofloxacin.
The first hours matter. The classic story is a snap or pop, a feeling of being kicked in the back of the heel, then weakness pushing off and no way of rising onto tiptoe. Because many people can still walk flat-footed and the pain may settle to a dull ache, it is tempting to wait and see. Don’t. A suspected rupture needs A&E or an injury unit the same day: a clinician checks it with a calf squeeze test, sometimes an ultrasound scan, and treatment in a boot or cast starts straight away. Timing matters too, because Cambridge University Hospitals lists presenting late, more than 2 to 3 weeks after the injury, as one of the situations where surgery is considered.
After that, it is a long, staged road. Cambridge University Hospitals describes about nine weeks in a boot, physio from the end of that, jogging from around 16 to 24 weeks, and return to sport at 4 to 12 months, with AAOS putting complete recovery at about a year. Surgery and a boot are both reasonable routes, and the choice is made with your orthopaedic team. Every timeframe here is a typical range, not a promise, and tracking the boot stages, swelling and strength week by week keeps the long middle of the recovery visible.
How bad is it?
An Achilles rupture isn't graded 1–2–3. It's described as partial (torn but still in one piece) or complete (torn all the way through, leaving two ends). Partial tears are rare, so Cambridge University Hospitals advises treating any sudden Achilles injury as a complete rupture. There are two common routes, and both are widely used: non-surgical treatment in a boot or cast with the toes pointing down, which that NHS trust uses for most patients and says gives similar results to surgery without its complications; and surgical repair, which Cleveland Clinic describes as the most common treatment for athletes and very active people. Either way, expect roughly 6 to 9 weeks in a boot or cast, and 4 to 12 months before a return to sport.
How long will it take?
Recovery moves in phases. This is the typical shape of it. Yours may run faster or slower, and the numbers below are general ranges, not a forecast for your specific injury.
When to get it looked at
Most cases settle with time and sensible loading. Get it assessed by a professional if any of these apply, as they can point to something that needs hands-on care:
- A sudden snap, pop or feeling of being kicked at the back of the heel or calf, with weakness pushing off: go to A&E or an injury unit the same day, even if you can still walk flat-footed
- Unable to stand on tiptoe or push off on that leg after an injury: get it assessed at A&E or an injury unit the same day
- New calf pain, swelling, or red or darkened skin in the leg while in a boot or cast or after surgery (possible blood clot): ask for an urgent GP appointment, contact your fracture clinic or call 111
- Shortness of breath or chest pain, especially while in a boot or after surgery: call 999 or go to A&E
- After surgery: a wound that is increasingly red, hot, leaking or opening, or a high temperature: contact your surgical team or GP the same day
- A new snap, pop or sudden loss of push-off strength during recovery (possible re-rupture): stop, protect the leg and get it assessed the same day
This is a list of warning signs, not a diagnosis. If you are worried, or the pain is severe, see a GP, physiotherapist or urgent care.
What to track while you recover
Achilles recovery is long and staged, with a boot schedule early on and slow strength gains later. A short daily record keeps the wedge changes, the swelling and the strength trend in one place, and makes any new calf pain stand out straight away.
- Pain score, 0–10, and swelling around the ankle and calf each evening
- Boot stage: how many wedges are in, and the date of the next change
- Any new calf pain, warmth, redness or swelling in the leg, especially while in the boot
- Out of the boot: walking distance, stairs, and later how many single-leg heel raises you can do on each side
- Sleep, rehab sessions done, and any trips, slips or awkward steps
This is exactly what InjuryLog does.

What to tell your physio
Achilles rehab is built around dates: when it happened, when the boot went on, when each wedge came out. A clinician needs that history as much as how it feels today. Bring it.
- The moment it happened: what you were doing, whether you heard a snap or felt kicked, and the date
- Your boot or cast plan: when it started, the wedge schedule, and any blood-thinning injections
- Whether you had surgery, and anything your surgeon said about the repair
- Current pain, swelling and walking, and how many single-leg heel raises you can manage on each side
- Your job, whether you drive a manual or automatic car, and your sport and return target
Walk in with the whole picture.

The questions people actually ask
How long does it take to recover from a ruptured Achilles?
Longer than most people expect, whichever treatment you have. The boot or cast phase is usually around 6 to 9 weeks: AAOS describes at least 6 weeks of immobilisation, and the Cambridge University Hospitals boot programme runs about nine weeks. That NHS trust then aims for normal walking and near-full ankle strength by around 16 to 24 weeks, with return to sport taking 4 to 12 months depending on the sport. AAOS puts complete recovery at about 12 months, with some people needing closer to 2 years to reach all their goals. These are typical ranges, not a promise for you.
What does an Achilles rupture feel like?
Most people describe a sudden pop or snap and a feeling of being hit or kicked at the back of the ankle or calf (Cleveland Clinic). The pain can be sharp and then settle to a dull ache, and some people feel very little pain at all (Cambridge University Hospitals; Cleveland Clinic). What follows is weakness: difficulty pushing off, climbing stairs or rising onto tiptoe, with swelling and bruising around the ankle and calf. Because it may not hurt much, people often wait and see. Don't: get it assessed the same day.
Can you walk with a ruptured Achilles tendon?
Often, yes, which is exactly why ruptures get missed. Many people can still walk, usually flat-footed, after a rupture (Cambridge University Hospitals). What they can't do normally is push off, climb stairs or rise onto tiptoe on that leg. Being able to walk does not mean the tendon is intact. A clinician checks with a calf squeeze (Thompson) test: if the tendon is intact, squeezing the calf makes the foot point down; if it is ruptured, the foot doesn't move. An ultrasound scan is sometimes used to confirm the rupture and its exact site.
Is surgery or a boot better for a ruptured Achilles?
Both are common and both work for most people. Cambridge University Hospitals treats most patients in a functional boot and says the evidence suggests similar results to surgery without its complications, putting the complication risk of surgery about 16% higher. Surgery tends to be considered for late presentation (more than 2 to 3 weeks after the injury), re-ruptures, certain tear types and some elite athletes. AAOS notes that some studies show better push-off strength and fewer re-tears after surgery, but says the evidence is still debated. The choice is made with your orthopaedic team, based on your injury, health and goals.
When can I drive after an Achilles rupture?
Cambridge University Hospitals advises not driving a manual car for at least nine weeks after the injury, then building up gradually. If it's your left Achilles and you drive an automatic, you may be able to drive sooner. Either way, you need to be able to do an emergency stop, and you should tell your insurer. Your fracture clinic team can advise on your own situation, since the timing depends on which leg it is, the type of car and how your recovery is going.
When can I return to sport after an Achilles rupture?
Typically somewhere between 4 and 12 months after the injury, depending on the sport, your strength and your skills (Cambridge University Hospitals). In that programme, jogging on a trampette starts around 16 to 24 weeks, progressing to running and change of direction under guidance, with hopping, skipping and sport-specific drills from about six months. Cleveland Clinic says getting back to sport or your previous activity level can take up to a year, and AAOS notes that regaining your previous activity level can take 18 to 24 months. Athletes usually complete a set of tests first, and the decision is made with your physio or surgeon.
Can an Achilles tendon rupture again?
Yes. Re-rupture is one of the main risks after either treatment (Cambridge University Hospitals; AAOS). Cambridge University Hospitals warns that the riskiest moments are sudden loads, such as tripping, stepping up stairs or jumping down from a height, and advises avoiding sudden stretching of the tendon for the first six weeks after the boot comes off. AAOS notes that some studies suggest surgically repaired tendons are less likely to re-tear, though this is still debated. A new snap, pop or sudden loss of push-off strength during recovery needs same-day assessment.
