Achilles rupture assessment helps guide treatment and rehab planning.

Achilles rupture is a tear of the tendon that links your calf muscles to your heel. It often happens during a sudden push-off, jump, trip, or change of direction.

You may feel a sharp pop at the back of the ankle. After that, walking often feels weak or awkward. Some people can still walk on flat ground, so the injury can be missed early.

Because the Achilles sits between the calf and heel, symptoms can overlap with heel pain, Achilles tendinopathy, and calf injuries. A prompt assessment helps confirm the injury and guide the next step. For general aftercare advice, see MedlinePlus Achilles tendon rupture aftercare.

Achilles Rupture Symptoms

An Achilles rupture often causes a sudden change in strength. Pain may settle, but push-off usually remains weak.

Common signs of a ruptured Achilles tendon

• A sudden snap or pop at the back of the ankle
• Pain and swelling around the Achilles and heel
• Trouble pushing off to walk, climb stairs, or jog
• Reduced calf strength
• A gap or dip in the tendon, although this is not always clear

Can you still walk on a ruptured Achilles?

Yes. Some people can still walk after an Achilles rupture, especially on flat ground. However, walking usually feels weak and uneven.

This is why care can be delayed. If you felt a pop and cannot push off well, arrange an assessment promptly.

What Causes an Achilles Tendon Rupture?

Most ruptures occur when the tendon is loaded faster than it can cope. Common triggers include forceful push-offs, tripping, awkward landings, and sudden sprinting.

Risk may rise with previous tendon pain, reduced calf strength, and sudden training spikes. Some health conditions, corticosteroid use, and certain antibiotics, such as fluoroquinolones, can also increase tendon risk in some people.

How Is an Achilles Rupture Diagnosed?

A physiotherapist will ask what happened, check swelling, test calf strength, and examine the Achilles tendon. Clinical tests, such as the Thompson test, may help confirm the injury.

Ultrasound or MRI may help when the diagnosis is unclear. Imaging can also help check tendon gap size and guide treatment planning.

Treatment Options for Achilles Tendon Rupture

Non-operative management

Many people recover well without surgery when care starts early and follows a clear plan. Non-operative care often uses a CAM boot or ankle brace with heel wedges. This protects the tendon while it heals.

Over time, the wedges reduce. The ankle then moves closer to neutral. Rehab then shifts to walking, strength, balance, and return-to-activity work.

When surgery may be considered

Surgery may suit some people. This can include certain tear patterns, delayed diagnosis, larger gaps, or higher performance needs.

Surgery may reduce re-rupture risk in some groups, but it can also increase wound, infection, or nerve risks. Your surgeon and physiotherapist can explain the trade-offs in plain language.

Achilles Rupture Rehabilitation Phases

Rehab must protect the tendon early, then rebuild strength and power over time. Progress should follow function, not just the calendar.

Phase	Main goal	Typical focus
Protection	Protect healing tendon	Boot, wedges, swelling control, safe walking
Strength	Rebuild calf capacity	Calf loading, balance, walking mechanics
Function	Restore daily activity	Stairs, longer walks, work tasks, light gym
Sport	Return with control	Running, jumping, cutting, sport drills

Phase 1: protection and safe movement

In the early weeks, the priority is tendon protection, swelling control, and safe mobility. Crutches may help at first. Hip and knee exercises can help maintain capacity while the ankle is protected.

Phase 2: progressive loading and strength

Next, rehab shifts to calf strengthening, balance, and walking mechanics. If you also have ankle pain or a history of sprained ankle, your plan should address those factors too.

Phase 3: return to running and sport

Return to running and sport depends on calf strength, tendon capacity, endurance, and confidence. It does not depend on time alone.

Many people need several months of progressive work. Some take closer to a year to feel strong again. A good plan often includes graded running and sport-specific drills, similar to the way we manage many running injuries.

How Long Does an Achilles Rupture Take to Heal?

Healing timelines vary. Tendon healing starts early, but strength and power take longer to rebuild.

Many people spend 6–12 weeks in protected rehab. Return to sport often takes 6–12 months. Your timeline depends on your treatment choice, baseline fitness, calf strength, and rehab progress.

What to Do Next

• Book an assessment soon if you felt a pop and cannot push off well.
• Avoid early stretching or repeated “testing” of the tendon.
• Use a boot, brace, or supportive shoe if advised.
• Start a staged plan that rebuilds walking, calf strength, and confidence.
• If imaging or surgical opinion is needed, your clinician can help guide the next step.

Achilles Rupture FAQs

What does an Achilles rupture feel like?

Many people feel a sudden pop or snap at the back of the ankle. Pain, swelling, and weak push-off often follow. Some people describe it as feeling like they were kicked in the back of the leg.

Can you still walk with a ruptured Achilles tendon?

Yes, some people can still walk on flat ground. However, walking usually feels weak, uneven, or awkward. If you cannot push off well, arrange an assessment soon.

Do you always need surgery for an Achilles tendon rupture?

No. Many people recover well with boot-based care and structured rehab. Surgery may suit selected cases, so the decision should consider tendon gap, timing, health, activity goals, and risk.

How long does Achilles rupture recovery take?

Recovery varies. Many people spend 6–12 weeks in protected rehab. Return to running or sport often takes 6–12 months, depending on strength, tendon capacity, and goals.

What should I avoid after an Achilles rupture?

Avoid stretching the tendon or repeatedly testing it early. Follow your boot, brace, or protection plan. Then progress loading step-by-step with clinical guidance.
