🦶 How does a lateral ankle sprain actually happen?
Ever wondered what happens when you “roll” your ankle?
A lateral ankle sprain most commonly occurs when the foot suddenly moves into:
↪️ Inversion – the sole of the foot turns inward
⬇️ Plantarflexion – the foot points downward
This combination places excessive stress on the lateral ankle ligaments, particularly the anterior talofibular ligament (ATFL) — the ligament most commonly injured in a lateral ankle sprain.
💥 Common mechanisms include:
• Landing awkwardly from a jump
• Stepping on an uneven surface
• Changing direction quickly
• Another player landing on your foot
• Missing a step
The ATFL is typically injured first. With greater forces, the calcaneofibular ligament (CFL) may also be involved, and in more severe injuries, the posterior talofibular ligament (PTFL) can be affected.
💡 But the injury doesn’t end when the swelling goes down.
Following a lateral ankle sprain, deficits in strength, balance, proprioception and confidence can persist — increasing the risk of recurrent ankle sprains.
That’s why proper rehabilitation matters. 🏃♂️💪
