Evaluating ankle sprains

ANKLE sprains are extremely common in sports.

Forty per cent of all athletic injuries involve the ankle. Most ankle sprains involve the lateral ligament complex.

In these sprains, approximately 80% of individuals recover fully and do not develop lateral ankle instability.

These ligaments are extra-articular (Figure 1). Complete ruptures of the ligaments
