Chronic Ankle Instability
 
What is chronic ankle instability?

This condition refers to abnormal motion in the ankle joint.  Normally, two ligaments keep the ankle joint from rolling inward (inverting) or outward (everting).  These ligaments are the anterior talofibular ligament and the calcaneofibular ligament.  If either of these ligaments ruptures, the ankle becomes unstable.
