Ankle Fracture Rehabilitation and Weight-Bearing Progression
Rehabilitation after an ankle fracture is critical to restore mobility, strength, and function. Progression depends on the type of fracture, surgical fixation, and individual healing. A structured protocol balances protection with early mobility to prevent stiffness and long-term disability.
Phase I: Immobilisation and Protection (0–6 weeks)
- Goal: Protect the fracture and reduce swelling.
- Immobilisation: Cast, boot, or splint is typically used.
- Weight-bearing:
- Non-displaced fractures: Partial weight-bearing may be allowed early.
- Post-surgical ORIF (open reduction, internal fixation): Usually non-weight-bearing for 4–6 weeks.
- Exercises:
- Isometric contractions (quads, glutes, calf).
- Toe curls and gentle circulation exercises.
- Maintain upper body and contralateral limb strength.
Phase II: Early Mobilisation (6–8 weeks)
- Goal: Restore range of motion (ROM) and begin weight-bearing.
- Weight-bearing: Progress from partial to full as guided by surgeon and X-ray confirmation of healing.
- Exercises:
- Active ROM: dorsiflexion, plantarflexion, inversion, eversion (within pain-free range).
- Gentle theraband strengthening.
- Pool therapy or cycling with minimal resistance.
Phase III: Strengthening and Proprioception (8–12 weeks)
- Goal: Improve stability, balance, and muscular endurance.
- Weight-bearing: Full, with gradual weaning off support (boot, crutches).
- Exercises:
- Closed-chain strengthening: mini-squats, heel raises.
- Balance tasks: single-leg stance, wobble board.
- Functional mobility: step-ups, walking on varied surfaces.
Phase IV: Functional Rehabilitation (3–6 months)
- Goal: Restore pre-injury activity levels and prevent re-injury.
- Exercises:
- Plyometrics: hopping, bounding (if appropriate).
- Agility drills: ladder drills, side-stepping.
- Sport-specific training for athletes.
- Return to sport: Generally after 4–6 months, depending on fracture type and healing.
Key Considerations
- Fracture stability and fixation determine early weight-bearing allowances.
- Smoking, diabetes, and osteoporosis may delay healing and require slower progression.
- Red flags: persistent swelling, severe pain, or hardware complications need urgent review.
- Long-term risk: post-traumatic osteoarthritis, particularly after intra-articular fractures.
✅ Conclusion
Ankle fracture rehabilitation must balance protection with progressive mobility. Early ROM, careful weight-bearing progression, and gradual strengthening are essential to restore safe function. Individualised programs, guided by surgical input, give the best outcomes.
