Is a tear of the anterior talofibular ligament bad?

Sprain: This ligament is the most common injured with a routine ankle sprain. Most will heal with rest, or immobilization. More severe injuries may require additional treatment.

Part of Ankle Sprain: A tear in the atf ligament is the most common ligament stressed and disrupted in ankle sprains. If you have a grade i ankle sprain, typically the atf ligament is the only one involved; however, with a tear, more than likely you have a more serious grade ii or iii sprain. Be sure to see a foot/ankle specialist to be properly examined and treated.
