**6. Grade III lateral ankle sprains**

Grade III lateral ankle sprains occur when there is a complete rupture of both ATFL and CFL. Although the initial line of management remains a functional rehabilitation, surgery should be considered if the symptoms persist. The feeling of giving way, defined as functional instability or true mechanical instability, is frequently experienced. This can be demonstrated by provocative tests such as the anterior drawer or talar tilt (either clinically or by stress radiography). Particular attention should be directed at the diagnosis and correction of subtle subtalar instability in individuals with functional instability. Surgical repairs are aimed at the reconstruction of the normal anatomy by overlapping the existing joint capsule and lateral ligaments. The rehabilitation protocol post-surgery remains the same as that of the conservative treatment.
