Ankle Instability
What is Ankle Instability
Ankle instability, which is usually chronic, is a condition characterized by a recurring giving away of the outside of the ankle. This condition often develops after repeated ankle sprains.
Causes
Ankle instability develops after an ankle sprain that has not adequately healed or was not rehabilitated completely. This results in laxity/looseness of the ligaments to the outside of the ankle which affects the ability to hold and stabilize the ankle. Additionally, ankle instability can be associated with those with high arch feet.
Symptoms
- Repeated turning or twisting of the ankle, especially on uneven surfaces or when participating in sports
- Persistent/chronic discomfort and swelling
- Pain or tenderness to the outside of the ankle
- Ankle feeling wobbly or unstable
Diagnosis
In evaluating and diagnosing your condition, the foot and ankle surgeon will ask you about any previous ankle injuries and instability. Then s/he will examine your ankle to check for tender areas, signs of swelling and instability of your ankle as shown in the illustration. X-rays or other imaging studies may be helpful in further evaluating the ankle.
Treatment
Non-surgical
- Physical therapy
- Bracing
- Medications- NSAIDs
Surgical
In more severe cases, surgery may be required to adequately treat an ankle sprain. Surgery often involves repairing the damaged ligament. The foot and ankle surgeon will select the surgical procedure best suited for your case based on the type and severity of your injury. After surgery, rehabilitation is extremely important. New technologies are now available which allow both the young athlete and the older patient to return to full activity with improved outcomes, early weight-bearing, and overall improved level of activity .
