Ankle Instability Surgery

Chronic ankle instability is when ligaments are stretched/torn and the ankle repeatedly “gives way”. If ankle instability has not responded to physiotherapy treatment then ankle ligament reconstruction is recommended.

A small incision is made along the outside of the ankle and the injured ligaments assessed. If a ligament has been stretched but not torn, it is cut and shortened, then the two ends are sewn together. If a ligament is torn but still remains attached to the fibula bone, the ends are repaired and sewn together. If a ligament is found to have pulled away from the fibula, it must be reattached. Stitches are used to attach the ligament to a small hole drilled in the fibula. A band of tissue that crosses the front of the ankle joint is used to reinforce the repair. The surgery will take approx 60 minutes. You will go home the same day. You will be able to walk immediately with the use of crutches for support.

Patients will need physiotherapy for up to 6 months after surgery. Rehabilitation after surgery can be a slow process and you should expect full recovery to take up to six months.

There are a number of risks associated with surgery:

  • Infection
  • Excessive stiffness
  • Damage to the blood vessels or nerves
  • New injury to the ankle causing damage to the repair
  • Ongoing instability
