Chronic Ankle Instability Introduction
Ankle instability is a condition characterised by the ankle ‘giving way’ or feeling wobbly and unreliable, particularly on uneven surfaces.
There are two main ligaments that support the ankle. The outer ligaments, known as the lateral ligaments, have three components which stop the ankle from rolling and sliding forward. These ligaments are attached to the fibula (small bone next to the shin bone) and the talus (the ankle bone) and calcaneus (heel bone).
An ankle sprain stretches and tears these ligaments and if the sprain doesn’t heal properly, ankle instability can develop.
