chronic ankle instability

What Causes Chronic Ankle Instability?

Chronic ankle instability usually develops following an ankle sprain that has not adequately healed or was not rehabilitated completely.

Repeated ankle sprains often cause – and perpetuate – chronic ankle instability.


  • A repeated turning of the ankle, espeically on uneven surfaces
  • Continued discomfort & swelling
  • Pain or tenderness


If your ankle feels unstable and gives way repeatedly, or if you experience recurring ankle sprains, your condition should be evaluated and treated. Chronic ankle instability that is left untreated leads to continued instability, activity limitations, arthritis, and tendon problems.

In evaluating and diagnosing your condition, Premier Podiatry Group will examine your ankle to check for tender areas, signs of swelling, and instability of your ankle as shown in the illustration. X-rays, CT scans, or MRIs may be needed to  further evaluate the ankle complex.


  • Physical therapy
  • Bracing – Can be found at our online store
  • Oral medication [Nonsteroidal Anti-Inflammatory Drugs (NSAIDs)]

In some cases Premier Podiatry Group will recommend surgery based on the degree of instability or lack of response to non-surgical approaches. The length of the recovery period will vary, depending on the procedure or procedures performed.
