What is lateral ankle instability?

Lateral ankle instability refers to ligamentous laxity (i.e., “loose ankle”) in the ankle, usually after multiple strains and sprains.  The most common ligament in the ankle that gets injured is the anterior talofibular ligament (aka “ATFL”).    This ligament, along with other ankle and lower leg ligaments, is very important in maintaining a balanced gait (i.e., walking straight).

What causes ankle instability?

As one goes through life, they may have sprained their ankle many times while playing sports, tripping and falling on uneven pavement, or has a job that requires a lot of climbing, bending, stopping, walking, etc.  As mentioned above, one may have sustained many strains and sprains in their lateral ankle.  Over time, this ligament is heavily scarred and/or does not heal correctly. This leads to an altered gait over time, making one unstable, especially when twisting, or walking on uneven surfaces.

What are the signs / symptoms of lateral ankle instability?

Common complaints include difficulty with exercising, difficulty wearing high heels.  Exercises that involved side-to-side movements is difficulty.  Walking on uneven surfaces is also very difficult.  In severe cases, one can see that the injured foot is more inverted than the non-injured foot at rest.
