Chronic Ankle Instability

Ankle Instability Ankle instability happens when the outside part of the ankle constantly "gives out" when putting weight it, especially when you're running or walking on uneven surfaces. It can even happen when you're standing. People with ankle instability often complain that the ankle feels wobbly or unstable. Because the condition is reoccurring, it is also known as chronic ankle instability.

What is the Cause?

Chronic ankle instability is usually caused by an ankle sprain that has not healed properly. During a sprain, the ligaments in your ankle may have been stretched or torn, and when they healed it resulted in weaker and "stretched out" ligaments. Individuals who participate in activities that involve the ankle, such as ballet and gymnastics or high-intensity sports like basketball or football, are at higher risk for chronic ankle instability. Those who suffer from repeated ankle sprains are also at risk for ankle instability.

What does it feel like? What are the symptoms?

A common symptom of ankle instability is the feeling of the ankle ready to give way. This may be heightened when walking on uneven ground or when wearing high heels. The instability may also be accompanied by pain on the outside of the ankle. Sometimes this pain is intense, and other times it may be a dull ache. Some patients also experience tenderness to the touch, stiffness, and swelling. You may occasionally "tweak" your ankle from mild activities like walking. By taking a close look at how you are walking and taking your steps, you may also notice that your ankle tends to roll or lean towards one side. Though this may be due to under or over-pronation, it can also be due to the weak ligaments surrounding your ankle. People with chronically unstable ankles will often complain of sore ankles after working out.

What is the Treatment?

Unless your ankle is severely injured, your ankle may benefit from some things you can do at home. As difficult as it is to hear, R.I.C.E. is recommended whenever you feel any onset of pain or soreness in your ankle. R.I.C.E. stands for rest, ice, compress and elevate.


Rest. Rest may be one of the most difficult things to do as it is difficult for many people to take a break from the activities they enjoy doing. However, rest gives your body time to recover and let the ligaments have a break in terms of supporting your body. If your ankles are sore, take a few days off. If there is mild to moderate pain, it may be beneficial to take a week or two off.


Cold therapy is a form of pain relief for many injuries. By applying a cold compress or ice pack to your ankle for 10 minutes at a time 2-3x a day, you will be able to help reduce any swelling or inflammation which can lead to pain relief.


Compression is important as it helps prevent swelling in the area. Try wrapping the ankle with the elastic wrap or do double-duty by using a compression ice wrap that both compresses and applies cold therapy like the DuraSoft Ankle Ice Wrap.


Anti-inflammatory medications such as ibuprofen or aspirin are often taken if the patient is experiencing pain, tenderness or swelling.

Increase Flexibility and Strengthen

By increasing the flexibility in your ankle and strengthening it, you can improve your ankle. Do exercises that help with increasing range of motion, improving balance, and strengthening the surrounding muscles. Every day, work on tracing the letters of the alphabet with your foot, making small to large circles inwards and outwards, stand on one foot to improve balance, to increase difficulty, stand on one foot on a balance ball or bosu ball, and strengthen with an elastic band.


If you feel the instability daily through walking or standing, wearing an ankle brace can help support your weak ankles. The Trizone Ankle Sleeve is recommended for daily use. If you are looking to stay active and play sports, we recommend an ankle brace that provides moderate protection. Use the DonJoy Stabilizing Ankle Brace or Aircast A60 for protection during sports. These can help steady your ankle as you walk and they may also prevent additional ankle sprains that lead to chronic ankle instability. In severe cases, a custom-made orthosis may be suggested.

If the above steps do not work, your physician may suggest surgery to repair the damaged ligaments in your ankle. Surgery is usually a last resort for ankle instability, so contact your doctor to see which is the best treatment for your injury.
