FOOT AND ANKLE / POSTOPERATIVE PROTOCOL

Bimalleolar ankle fracture — rehabilitation after fixation

Fixation of both lateral and medial malleolar fractures. Progression depends on stability at both sites, bone quality, wound condition and any syndesmotic fixation.

For clinicians, physiotherapists and patients. The individual plan based on the operative report takes precedence over the time ranges on this page.

Essential protection

Weight-bearing
Early weight-bearing may be considered after stable fixation, often from the review around week 2; some patients are allowed to load earlier. Concerns about fixation, the wound or sensation require a longer protective pathway prescribed by the surgeon.
Brace / immobilisation
Splint/cast or walking boot according to stability and wound condition.
Range of motion
Active movement after clearance; movement permission does not imply permission for resistance or full loading.

Each phase has its own illustration. The descriptions below are the text equivalent of the board. Doses are starting examples to individualise with a physiotherapist and do not override surgical restrictions.

Positioning and swelling control — Bimalleolar ankle fracture — rehabilitation after fixation. Prepared by Tomasz Poboży — orthopaedic surgeon.
Phase 1 · Weeks 0–2

Positioning and swelling control

In lying or reclining, support the calf on broad cushions. Avoid pressure on the wound or heel. Keep the prescribed support in place; elevation does not replace safe mobilisation.

Dose to individualise
Short periods of elevation after activity; change position regularly.
When to reduce or stop
Pressure, numbness, pale toes or pain under the support require assessment.

Gentle active ankle movement — Bimalleolar ankle fracture — rehabilitation after fixation. Prepared by Tomasz Poboży — orthopaedic surgeon.
Phase 2 · Weeks 2–6

Gentle active ankle movement

Sit with the lower leg supported and the foot free to move. Once removal of the boot is permitted, gently move the foot towards and away from you. Use active movement, without pulling with a towel or having another person force the joint.

Dose to individualise
Starting dose to individualise: 5–10 slow repetitions, 3–5 short sessions daily, within the permitted range.
When to reduce or stop
Reduce range and dose for sharp pain, wound tension or increased swelling after the session.

Seated heel raise — Bimalleolar ankle fracture — rehabilitation after fixation. Prepared by Tomasz Poboży — orthopaedic surgeon.
Phase 3 · Usually weeks 6–12

Seated heel raise

Once forefoot pressure is permitted, sit with both feet on the floor. Raise the heels a small distance while keeping the forefeet supported, then lower slowly. Do not add weights to the knees.

Dose to individualise
For example, 1 set of 8–12 repetitions; increase only if symptoms remain stable after the session and the next day.
When to reduce or stop
Reduce the range or defer the exercise if the heel, metatarsals or malleoli hurt.

Check this phase’s restrictions and criteria →

Low step-up — Bimalleolar ankle fracture — rehabilitation after fixation. Prepared by Tomasz Poboży — orthopaedic surgeon.
Phase 4 · From around week 12; criteria based

Low step-up

Stand by a handrail. Place the entire operated foot on a low step and step up slowly while controlling the knee and pelvis. Adjust step height to ability; introduce step-downs separately because they require different control.

Dose to individualise
Initially use a step around 10 cm high, 5–8 supported repetitions, once level walking is free of limping.
When to reduce or stop
Avoid pushing off forcefully with the other leg; do not increase height with pain or knee collapse.

Who this protocol is for

Fixation of both lateral and medial malleolar fractures. Progression depends on stability at both sites, bone quality, wound condition and any syndesmotic fixation.

Adults after fixation of a closed fracture. Open fractures, infection, neuropathy, vascular compromise, pilon injuries, cartilage repair and multiple injuries require a separate plan.

Before starting, confirm the operation date and extent, fixation, permitted loading, support-removal rules, range of motion and review date. Obtain any missing instruction from the surgeon before progressing.

Full programme by phase

01 · Protection and independenceWeeks 0–2
Goal
Safe transfers, swelling control and protection of the wound and fixation.
Weight-bearing
Follow the prescribed loading level exactly. If it is undocumented, contact the surgeon before increasing load; do not independently adopt weight-bearing as tolerated.
Support / immobilisation
Splint, cast or walking boot as discharged. Remove only when permitted.
Motion
Move the knee, hip and unrestricted toes. Move the ankle only after clearance to mobilise and remove the support; do not force it.
Work in this phase
Practise safe sit-to-stand transfers and short-distance mobility. Maintain thigh activation without resistance through the foot. Follow the individual thromboprophylaxis prescription.
Progression criteria
Wound and circulation assessed, swelling controlled, loading prescription understood and aids used safely.

See the exercise or activity for this phase →

02 · Movement with protectionWeeks 2–6
Goal
Restore gentle movement without jeopardising repaired tissues.
Weight-bearing
Early weight-bearing may be considered after stable fixation, often from the review around week 2; some patients are allowed to load earlier. Concerns about fixation, the wound or sensation require a longer protective pathway prescribed by the surgeon.
Support / immobilisation
Usually a removable walking boot when the wound and stability permit. Night-time use follows the surgeon’s instructions; do not discontinue it independently.
Motion
Gentle active movement, initially dorsiflexion and plantarflexion. Add inversion and eversion only when cleared, particularly after ligament repair. Avoid forceful stretching and fracture-site mobilisation.
Work in this phase
Use short movement sessions several times daily. Continue hip and knee strengthening without foot loading. Practise gait within the prescribed load and avoid pivoting on the operated leg.
Progression criteria
Clinical and imaging review confirms maintained alignment, without worsening wound or increasing pain. Further resistance and loading progression have been authorised.

See the exercise or activity for this phase →

03 · Walking and strength recoveryUsually weeks 6–12
Goal
Gradual return to footwear and walking without a limp.
Weight-bearing
Progress only after clearance based on healing and stability. Move from two crutches to one, usually contralateral, then no aid, provided gait quality is maintained.
Support / immobilisation
Wean from the walking boot in stages once cleared. Choose supportive footwear; swelling may require a wider shoe.
Motion
Gradually expand active movement and, after healing assessment, gentle assistance. Do not force symmetrical angles at the expense of pain.
Work in this phase
Add light resistance and weight-bearing exercises within the loading limit. Start stationary cycling only when pedal loading and required motion are permitted. Increase one variable at a time.
Progression criteria
Walking in shoes without a significant limp, no marked next-day reaction, improving motion and strength, and healing adequate for further progression.

See the exercise or activity for this phase →

04 · Function and return to activityFrom around week 12; criteria based
Goal
Restore limb control, stair function, endurance and task-specific capacity.
Weight-bearing
Full weight-bearing after clearance. Running, jumping and direction changes require confirmed healing, adequate strength and control, and no pain or swelling response.
Support / immobilisation
Usually supportive footwear. Additional bracing requires a specific indication and does not replace neuromuscular recovery.
Motion
Range sufficient for gait and functional tasks; persistent mechanical block, joint pain or increasing stiffness requires reassessment.
Work in this phase
Progress calf strengthening, balance and functional tasks. Before sport, assess both limbs, movement quality and endurance; symmetry alone is insufficient if both limbs are weak.
Progression criteria
Treating-team clearance, no fracture-site pain, safe stairs and work- or sport-specific tasks, without deterioration after loading or the following day.

See the exercise or activity for this phase →

How to adjust the dose

Increase one element at a time: repetitions, distance, range or resistance. Sharp pain, limping or markedly increased swelling calls for reducing the load. Check symptoms after exercise and the following day; discuss persistent deterioration. Absence of pain does not replace union assessment.

If the surgeon prescribes a kilogram limit, record the value and duration. Do not independently convert “as tolerated” into kilograms. Do not add weights without clearance for resistance.

Everyday activities and return to function

Walking and stairs
Use aids while needed to respect the load restriction and maintain gait quality. Practise stairs with a physiotherapist; choose a safer alternative when support or a rail is unavailable.
Driving
Resume only after assessment of rapid, forceful emergency braking and without medication impairing alertness. Operated side, transmission, bracing and loading restrictions affect the decision; discuss it with the treating team and consider insurance conditions.
Work, rest and swelling
Seated work requires opportunities to change position and elevate the leg; standing or manual work requires loading and task tolerance. Swelling may persist, but new or rapidly increasing swelling requires assessment.
Wound care and prevention
Do not soak an unhealed wound, remove wires yourself or change prescribed thromboprophylaxis. Follow individual medication, dressing, compression and scar-care instructions. Swimming requires complete wound closure and clearance.
Running and sport
Timing follows healing and capacity; it is not a stand-alone criterion. Establish safe gait, strength, balance and task tolerance first, progressing without significant next-day worsening.

Warning signs — when to seek help

Emergency help
Sudden shortness of breath, chest pain, collapse or coughing up blood: call emergency services. Use 112 in the EU; elsewhere use the appropriate local emergency number.
Urgent same-day assessment
New one-sided calf pain and swelling; increasing pain despite rest; fever with wound redness or discharge; wound breakdown; a new injury or pain after accidental loading.
Do not wait for a routine appointment
A cold, pale or blue foot, rapidly increasing numbness, loss of toe movement or severe increasing pain under a cast requires immediate emergency assessment.

Variants and clinical context

  • Stable fibular fixation does not establish readiness of the medial malleolus. A vertical or comminuted medial fracture may require longer protection.
  • The treating surgeon must establish fixation stability. No implant protects against every overload.
  • The WAX trial supports considering weight-bearing from week 2 in appropriately selected adults after ankle fracture surgery. It does not establish immediate unprotected walking for every patient.

Glossary
ROM
Joint range of motion. Active movement uses your own muscles; assisted movement uses additional help.
Non-weight-bearing
No body-weight transfer through the operated foot during standing and walking.
As tolerated
Once this pathway is authorised: loading limited by symptoms and movement quality within prescribed protection. It is not permission for unrestricted sport.
Walker
A walking boot is a protective ankle-foot support. A walking frame is a separate mobility aid.
