What Is an Ankle Fracture?

An ankle fracture is a break in one or more bones that form the ankle joint. The injury may involve the outside ankle bone, inside ankle bone, back of the tibia, or the talus below the ankle joint.

Some ankle fractures are stable. Others are unstable, displaced, or linked with ligament injury. A higher-energy injury may also involve a syndesmosis injury, which affects the strong joint system between the tibia and fibula.

Treating an Ankle Fracture

Treatment depends on fracture stability, bone position, swelling, skin condition, and whether the ankle joint stays aligned. Imaging, usually X-ray, confirms the diagnosis. In some cases, CT helps clarify joint involvement.

Early care usually focuses on simple priorities: protect the ankle, settle swelling, and keep the rest of the leg active where safe. For practical aftercare tips, see this MedlinePlus guide: ankle fracture aftercare.

Non-Surgical Management

Stable fractures may heal with immobilisation, such as a cast or a moon boot. Your team will usually set weight-bearing limits based on fracture pattern and healing stage. These may include non-weight-bearing, partial weight-bearing, or full weight-bearing.

Regular review helps confirm that the fracture stays well-aligned. Your physiotherapist can help maintain safe movement, strength, and mobility while you follow your medical plan.

Surgery for Unstable Fractures

Unstable or displaced fractures often need surgery, commonly open reduction and internal fixation, or ORIF. Surgeons use plates and screws to restore alignment and stabilise the ankle.

After surgery, rehab protects the repair while you gradually restore motion, strength, walking capacity, and confidence. Weight-bearing timing must follow your surgeon’s instructions.

Physiotherapy After a Broken Ankle

Physiotherapy after a broken ankle supports recovery in phases. First, you protect healing tissue and reduce swelling. Next, you restore ankle mobility and rebuild calf and foot strength. Finally, you retrain balance, walking, stairs, work tasks, and higher-level activity.

Ankle Fracture Rehab Timeline

Your rehab timeline depends on fracture type, surgery, swelling, X-ray review, weight-bearing instructions, and goals. Use this as a guide only. Your surgeon, GP, or physiotherapist may adjust each stage.

Stage	Main Goal	Common Focus	Progress Sign
Early phase	Protect healing	Swelling control, safe movement, hip and knee strength	Pain and swelling are settling
Middle phase	Restore movement and strength	Ankle mobility, calf strength, walking pattern	Walking improves without a strong limp
Later phase	Rebuild control and confidence	Balance, stairs, calf endurance, single-leg control	You trust the ankle during daily activity
Return phase	Return to work, sport, or running	Load testing, hopping, graded running, or work-specific drills	The ankle tolerates load without a next-day flare

Early Phase: Swelling, Pain, and Safe Movement

Early rehab often includes gentle ankle and toe movement within your medical limits, swelling management, and strength work above and below the injury. Your physiotherapist may also work on knee and hip strength so your movement stays steady while the ankle heals.

Middle Phase: Restore Range and Strength

Once your fracture shows healing and your team clears you to progress, rehab usually targets:

• ankle dorsiflexion and calf flexibility
• calf strength and endurance
• foot and ankle control, especially single-leg stability
• walking pattern retraining
• confidence with stairs, slopes, and uneven ground

Later Phase: Balance and Proprioception

Balance retraining helps you trust the ankle again. Time in a boot can reduce joint position sense and reaction speed. Many rehab plans include progressive balance drills and stepping tasks to rebuild control and reduce re-injury risk.

Helpful next reads include balance and proprioception exercises and balance training.

How Long Does a Broken Ankle Take to Heal?

Bone healing often takes around six weeks, but full recovery usually takes longer. Your timeline depends on fracture type, surgery if required, time in a boot, swelling, and how quickly you rebuild calf strength and walking tolerance.

Many people take 10 to 12 weeks or longer to feel more normal with day-to-day walking. Running, field sport, heavy work, and uneven-ground activity often take longer again.

Return to Work, Sport, and Running

A safe return depends on your strength, swelling, mobility, balance, work demands, and confidence. Your physiotherapist may use practical milestones rather than time alone.

• walking without a limp for a set distance
• good ankle mobility for stairs and squatting
• single-leg balance control
• quality single-leg calf raises with improving endurance
• low swelling response after activity
• safe hopping, landing, or change-of-direction control if sport requires it

If running is one of your goals, a graded return program can reduce flare-ups and rebuild capacity. Read: running injuries and return-to-run planning.

What to Do Next

If you think you have an ankle fracture, get assessed promptly. Once your fracture plan is clear, focus on steady progress rather than rushing the next stage.

• Follow your weight-bearing and boot or cast instructions.
• Keep swelling down with elevation and gentle movement, as allowed.
• Start rehab early, then progress strength and balance when cleared.
• Ask about return-to-work and return-to-sport milestones before increasing load.

If your ankle still feels stiff, weak, swollen, or unreliable after the early healing stage, physiotherapy may help you rebuild movement, strength, balance, and confidence.

Ankle Fracture FAQs

Do I need surgery for an ankle fracture?

Not always. Stable fractures may heal well in a cast or moon boot. Displaced or unstable fractures often need surgery to restore alignment and ankle stability. A doctor or surgeon decides this based on X-ray findings and joint stability.

How long does an ankle fracture take to heal?

Bone healing often takes around six weeks, but full recovery usually takes longer. Many people take 10 to 12 weeks or more to regain comfortable walking, and longer again for running or sport, depending on fracture severity and rehab progress.

When can I start weight bearing after a broken ankle?

Weight-bearing timing depends on fracture type and whether you had surgery. Some people progress earlier, while others need longer protection. Follow your surgeon or doctor’s instructions, then progress under physiotherapy guidance.

What does physiotherapy do after an ankle fracture?

Physiotherapy may help reduce swelling and stiffness, restore ankle mobility, rebuild calf and foot strength, and retrain balance and walking. Later stages may include return-to-work and return-to-sport drills based on your goals.

Can a broken ankle cause long-term stiffness or arthritis?

It can. Joint injuries and long periods of immobilisation may increase stiffness and, in some cases, post-traumatic arthritis. A staged rehab plan that rebuilds movement, strength, and balance may reduce long-term issues.
