Rehabilitation Guidelines for Total Ankle Replacement



Initial rehabilitation phase
0-4 weeks

Goals:
  • To be safely and independently mobile with appropriate walking aid, adhering to weight bearing status
  • To be independent with home exercise programme as appropriate
  • To understand self management / monitoring, e.g. skin sensation, colour, swelling, temperature, circulation

Restrictions:
  • Ensure that weight bearing restrictions are adhered to:
    • Total Ankle Replacement (TAR):
      • Non Weight Bearing (NWB) for 2 weeks in Back Slab
      • Below Knee Plaster of Paris (BK POP) at 2 weeks. Progress to Full Weight Bearing (FWB) in POP.
      • POP removed at 4 weeks. May require aircast boot. FWB.
    • If any other surgical technique used ensure you check any restrictions with team as these may differ from TAR alone
  • Elevation
  • If sedentary employment, may be able to return to work from 4 weeks post-operatively, as long as provisions to elevate leg, and no complications

Treatment:
  • Likely to be in POP
  • Pain-relief: Ensure adequate analgesia
  • Elevation: ensure elevating leg with foot higher than waist
  • Exercises: teach circulatory exercises
  • Education: teach how to monitor sensation, colour, circulation, temperature, swelling, and advise what to do if concerned
  • Mobility: ensure patient independent  with transfers and mobility, including stairs if necessary

Recovery rehabilitation phase
4 weeks – 3 months

Goals:
  • To be independently mobile out of aircast boot
  • To achieve full range of movement
  • To optimise normal movement

Restrictions:
  • Ensure adherence to weight bearing status.
  • No strengthening against resistance until at least 3 months post-operatively of any tendon transfers if performed.
  • Do not stretch any tendon transfers / ligament reconstructions if performed. They will naturally lengthen over a 6 month period

Treatment:
  • Pain relief
  • Advice / Education
  • Posture advice / education
  • Mobility: ensure safely and independently mobile adhering to appropriate weight bearing restrictions. Progress off walking aids as able once reaches FWB stage.
  • Gait Re-education
  • Wean out of aircast boot once advised to do so, and provision of plaster shoe as appropriate, if patient unable to get into normal footwear
  • Exercises:   
    • Passive range of movement (PROM)
    • Active assisted range of movement (AAROM)
    • Active range of movement (AROM)
    • Strengthening exercises as appropriate
    • Core stability work
    • Balance / proprioception work once appropriate
    • Stretches of tight structures as appropriate (e.g. Achilles Tendon), not of tendon transfers / ligament reconstructions if performed.
    • Review lower limb biomechanics. Address issues as appropriate.
    • If tendon transfer performed, encourage isolation of transfer activation without overuse of other muscles. Biofeedback likely to be useful.
  • Swelling Management
  • Manual Therapy:
    • Soft tissue techniques as appropriate
    • Joint mobilisations as appropriate ensuring awareness of osteotomy sites and those joints which may be fused, and therefore not appropriate to mobilise
  • Monitor sensation, swelling, colour, temperature, circulation
  • Orthotics if required via surgical team
  • Hydrotherapy if appropriate
  • Pacing advice as appropriate

Intermediate rehabilitation phase
12 weeks – 6 months

Goals:
  • Independently mobile unaided
  • Wearing normal footwear
  • Optimise normal movement
  • Grade 5 muscle strength around ankle
  • Grade 4 muscle strength of tendon transfers if performed

Treatment:
Further progression of the above treatment:
  • Pain relief
  • Advice / Education
  • Posture advice / education
  • Mobility: Progression of mobility and function
  • Gait Re-education
  • Exercises:   
    • Range of movement
    • Strengthening exercises as appropriate
    • Core stability work
    • Balance / proprioception work
    • Stretches of tight structures as appropriate (e.g. Achilles Tendon), not of transfers / ligament reconstructions if performed.
    • Review lower limb biomechanics. Address issues as appropriate.
    • If tendon transfer performed progress isolation of transfer activation without overuse of other muscles. Biofeedback likely to be useful.
  • Swelling Management
  • Manual Therapy:
    • Soft tissue techniques as appropriate
    • Joint mobilisations as appropriate ensuring awareness of those which may be fused and therefore not appropriate to mobilise
  • Monitor sensation, swelling, colour, temperature, circulation
  • Orthotics if required via surgical team
  • Hydrotherapy if appropriate
  • Pacing advice as appropriate


Final rehabilitation phase
6 months – 1 year

Goals:
  • Return to gentle no-impact / low-impact sports
  • Establish long term maintenance programme
  • Grade 4 or 5 muscle strength of tendon transfers if performed

Treatment:
  • Mobility / function: Progression of mobility and function, increasing dynamic control with specific training to functional goals
  • Gait Re-education
  • Exercises:   
    • Progression of exercises including range of movement, strengthening, transfer activation, balance and proprioception, core stability
  • Swelling Management
  • Manual Therapy:
    • Soft tissue techniques as appropriate
    • Joint mobilisations as appropriate ensuring awareness of those which may be fused and therefore not appropriate to mobilise
  • Pacing advice 
Failure to progress

If a patient is failing to progress, then consider the following:

POSSIBLE PROBLEM
ACTION
Swelling
Ensure elevating leg regularly
Use ice as appropriate if normal skin sensation and no contraindications
Decrease amount of time on feet
Pacing
Use walking aids
Circulatory exercises
If decreases overnight, monitor closely
If does not decrease overnight, refer back to surgical team or to GP
Pain
Decrease activity
Ensure adequate analgesia
Elevate regularly
Decrease weight bearing and use walking aids as appropriate
Pacing
Modify exercise programme as appropriate
If persists, refer back to surgical team or to GP
Breakdown of Wound e.g inflammation, bleeding, infection
Refer to surgical team or to GP
Transfer not activating
Start working in NWB gravity eliminated position with AAROM and then build up as able
Biofeedback
Ensure adequate analgesia as appropriate
Ensure swelling under control as appropriate
Ensure foot neutral when mobilising to avoid excessive shear. Consider orthotics referral via surgical team if unable to keep neutral
Refer back to surgical team if no improvement
Numbness / altered sensation
Review immediate post-operative status if possible
Ensure swelling under control
If new onset or increasing refer back to surgical team or GP
If static, monitor closely, but inform surgical team and refer back if deteriorates or if concerned
Summary of evidence for physiotherapy guidelines

A comprehensive literature search was carried out to identify research relating to surgery for tibialis posterior tendon dysfunction and subsequent rehabilitation. After reviewing the articles and information, the physiotherapy guidelines were produced on the best available evidence.
