Chronic ankle instability (CAI) develops when an ankle repeatedly rolls or feels unstable after previous injuries. Without proper treatment, this instability can lead to ongoing discomfort and a higher risk of additional sprains.

What Is Chronic Ankle Instability?
Chronic ankle instability occurs when the outer side of the ankle repeatedly gives way during movement or even while standing. This condition happens most often after multiple ankle sprains that have weakened or stretched the ligaments responsible for stabilizing the joint.
The ankle depends on a network of ligaments, muscles and tendons to maintain balance and support. When these structures are damaged and do not fully heal, the ankle can become unstable, making it easier for the joint to roll again.
Chronic ankle instability is common among athletes but can affect anyone who has experienced repeated ankle injuries.
What Causes Chronic Ankle Instability?
The most common cause of chronic ankle instability is a previous ankle sprain that did not fully heal or was not properly rehabilitated.
When an ankle sprain occurs, the ligaments that stabilize the joint may stretch or tear. If the ankle is not strengthened and retrained afterward, the surrounding muscles and balance systems may remain weak. This increases the risk of repeated sprains.
Over time, each additional injury can further stretch or damage the ligaments, creating a cycle of instability and increasing the likelihood of future problems.
Chronic Ankle Instability Symptoms
People with chronic ankle instability experience recurring symptoms that affect daily movement and activity, which may include:
- Repeated rolling or turning of the ankle
- Difficulty walking on uneven surfaces
- Persistent swelling or discomfort
- Pain or tenderness around the ankle
- A feeling that the ankle is loose, wobbly or unstable
Symptoms may become more noticeable during exercise or prolonged standing.
Chronic Ankle Instability Treatment
Treatment depends on the degree of instability and your activity level.
Many patients improve with conservative care designed to strengthen and stabilize the ankle. Treatment may include:
- Physical therapy, focusing on strengthening the ankle and improving balance and range of motion
- Ankle bracing, to support the joint and reduce the risk of further sprains
- Anti-inflammatory medications to reduce pain and swelling
Rehabilitation programs often include sport-specific exercises to help athletes safely return to activity after chronic instability of the ankle.
Chronic Ankle Instability Surgery
If symptoms continue despite nonsurgical treatment, surgery may be recommended to restore stability to the ankle.
Surgical treatment typically involves repairing or reconstructing the damaged ligaments. The specific procedure depends on the severity of the instability, the condition of the ligaments and your activity level.
Recovery time varies depending on the procedure performed, but rehabilitation and strengthening exercises are an important part of returning to normal activity.
Outlook and Recovery
With proper treatment and rehabilitation, many people with chronic ankle instability regain strength and confidence in their ankle.
Early treatment can help prevent additional injuries and long-term joint damage. Strengthening exercises, supportive footwear and bracing during high-risk activities can help reduce the risk of future sprains.
When Should You See an Ankle Specialist?
You should seek medical evaluation if:
- Your ankle repeatedly rolls or gives way
- Pain or swelling persists after a sprain
- Your ankle feels unstable during everyday activities
- You experience frequent ankle injuries
Prompt evaluation can help prevent further damage and restore proper joint function, so you can get back on your feet.
