    Chronic ankle instability is usually caused by an ankle sprain or injury. Ankle sprains are a very common and frequently occurring sporting injury. Most ankle sprains settle down and never cause any further problems. About 20-30% of ankle sprain injuries go on to cause problems. Usually this is a result of damaged ligaments that have not healed properly. Common causes of chronic ankle instability include:

    Repeated ankle sprains

    Isolated ankle sprain

    Vague significant injury to the ankle
