What is chronic ankle sprain?

What is a chronic ankle ligament sprain (also known as chronic ankle instability)?
The outer (lateral) aspect of the ankle is stabilised by a series of ligaments. These ligaments are commonly sprained when tripping over, twisting the ankle or during a tackle whilst playing football. When these ligaments are injured, the ankle can become unstable resulting in further ligament sprains and continued pain. Nearly half of all patients who sustain an ankle ligament sprain report long term ankle pain and instability.
What are the symptoms of a chronic ankle ligament sprain?
Symptoms of a chronic ankle ligament sprain are:
A history of a significant traumatic event
Multiple ankle injuries over time
Swelling and bruising over the outer aspect of the foot and ankle after injury
Cracking noises from the ankle with walking
Ankle stiffness
Pain around the lateral malleolus (the large bony bump on the outside of the ankle)
