What is a Lateral Ankle Sprain (ATFL/CFL/PTFL Tear)?

The talocrual joint of the ankle is between the tibia and the talus. It allows the ankle to move into plantflexion and dorsiflexion (point foot up and down). The joint is supported by 3 major ligaments called the anterior talofibular ligament (ATFL), posterior talofibular ligament (PTFL) and calcaneofibular ligament (CFL). These ligament prevent the bones from spreading part and provide feedback to the brain of where the ankle is when walking, running, jumping and hopping.

What are the Signs and Symptoms of a Lateral Ankle Sprain (ATFL/CFL/PTFL Tear)?

+ Feeling of instability in the ankle

+ Loss of movement in the ankle

+ Swelling of the foot and ankle

+ Pain with raising onto the toes (calf raise)

+ Pain with rolling the foot inwards

What is the Treatment of a Lateral Ankle Sprain (ATFL/CFL/PTFL Tear)?

The Physiotherapist will need to determine what grade of sprain has occurred of the ligaments. If the ankle sprain is a low grade such as a 1 or 2 then a boot is not required and the patient is encouraged to weight bear immediately. The Physiotherapist will guide you with gentle strengthening and balance exercises with the aim of returning to sport at 3-4 weeks post injury.

For higher grade tears such as a grade 3 the Physiotherapist may place you in a boot to help reduce pain and encourage gentle weight bearing. The Physiotherapist will then guide you with a strengthening and balance program from weeks 3 onwards, with the aim of returning to sport at 6 weeks post injury.
