Frequently Asked Questions

What is chronic ankle instability?

Chronic ankle instability is a condition where the ankle repeatedly feels weak, loose, or gives way. It often develops after one or more ankle sprains. The ankle may feel unstable during sports, walking, or uneven ground.

What causes chronic ankle instability?

It is commonly caused by incomplete healing or rehab after an ankle sprain. Weakness, poor balance, and stretched ligaments can all contribute. Repeated sprains increase the risk over time.

What are the symptoms?

Symptoms include repeated rolling of the ankle, swelling, pain, and a feeling of looseness. Some people avoid sports or uneven surfaces because the ankle feels unreliable. Balance and cutting movements may be difficult.

How is chronic ankle instability treated?

Treatment usually starts with physical therapy focused on balance, strength, and neuromuscular control. Bracing or taping may help during sports. Surgery may be considered if instability continues despite good rehab.

Can I return to sports with ankle instability?

Many athletes return to sports with therapy and bracing. Return should be based on strength, balance, and confidence with sport-specific movements. Recurrent giving-way episodes should be evaluated.
