definition of chronic ankle instability

Chronic ankle instability (CAI) is when someone keeps getting ankle sprains or feels like their ankle is wobbly, even after the first injury heals. This usually happens if the ankle wasn’t treated or rehabbed properly after the sprain.

An ankle sprain is when the ligaments around the ankle get stretched or torn, often from twisting or turning the foot. If the first injury isn’t taken care of right or the rehab isn’t done fully, it can cause ongoing problems with how stable and useful the ankle is.


chronic ankle instability causes and symptoms

CAI can happen for different reasons, usually starting with not treating or rehabbing an ankle sprain properly. Some common causes include:

Ligaments Not Healing Right: If the ligaments hurt in the first ankle sprain don’t heal properly, they can stay weak or stretched, making the ankle unstable.

Not Enough Rehab: Skipping proper rehab after an ankle sprain can lead to weaker muscles, less feeling of where the body is (proprioception), and less overall ankle stability.

More Sprains: Each time you sprain your ankle again, it raises the chance of chronic instability. Multiple sprains can damage ligaments and other supports.

Weak Muscles: Weak muscles around the ankle, especially the peroneal muscles on the outside of the lower leg, can make instability worse. Muscle imbalances can affect how well you can control your ankle’s movement and stability.

Loose Joints: Some people naturally have looser ligaments and joints, making them more likely to have ankle instability, especially after a sprain.


Common symptoms of CAI include:

Recurrent Sprains: People with CAI often keep getting ankle sprains, sometimes with little or no injury.

Feeling of Giving Way: There’s often a feeling that the ankle is giving way or buckling, even during normal activities.

Swelling and Pain: Swelling and pain may keep happening, especially after being active or standing for a long time.

Weakness: You might feel like the ankle is weak, affecting how well you can balance and use it.


chronic ankle instability (CAI) diagnose

To diagnose chronic ankle instability (CAI), a healthcare professional, like a sports medicine physician, orthopedic surgeon, or physical therapist, usually does a thorough evaluation. Here’s what the process may involve:

  1. Medical History

    The healthcare provider will ask about your medical history, including past ankle injuries, how often you’ve had sprains, and if you’re still dealing with instability symptoms.

  2. Physical Examination

    They’ll carefully check your ankle joint, looking at things like how it moves, its strength, and if it feels stable. Specific tests may be done to check the ligaments and see if there are signs of instability.

  3. Functional Assessment

    Your ability to do everyday activities like walking, running, and keeping balance will be assessed to find any issues or unusual movement patterns.

  4. Imaging Studies

    While not always needed, imaging studies like X-rays can be ordered to rule out other causes or to see how badly the ligaments are damaged. MRI may be used for a detailed look at soft tissues, including ligaments.

  5. Stress Testing

    Specific forces are applied to the ankle joint to see how stable it is. Tests like the anterior drawer test or talar tilt test may be used to stress the ligaments.


If you’re struggling with chronic ankle instability symptoms, it’s really important to tell your healthcare provider all about your symptoms and any past ankle injuries when they check you. This helps them figure out exactly what’s going on and make a plan to help you.

Once they know what’s up, the plan to treat chronic ankle instability might include non-scary stuff like physical therapy, exercises to make your ankle stronger, learning how to feel where your body is better (that’s called proprioception), and using things like braces or special shoe inserts for support. If things are super serious or these treatments don’t work, they might talk about surgery, like fixing up the ligaments in your ankle.


best treatment for chronic ankle instability

The treatment of chronic ankle instability (CAI) typically involves a combination of conservative measures and, in some cases, surgical intervention. Here are some common approaches to address chronic ankle instability:

  1. Physical Therapy:
    • Strengthening Exercises:
      • Focusing on muscles around the ankle, especially the peroneal muscles on the outside of the lower leg.
      • This strengthens the ankle, offering improved support and stability to the joint.
    • Range of Motion Exercises:
      • Engaging in exercises that boost flexibility and widen the range of motion in the ankle joint.
    • Proprioceptive Training:
      • Participating in exercises targeted at improving proprioception.
      • This enhances the body’s awareness of its position in space, leading to better balance and stability.
  2. Bracing and Supportive Devices:
    • Ankle Braces: Supportive ankle braces or taping techniques may be recommended to provide additional stability during activities.
    • Orthotics: Custom orthotic devices can help address any underlying issues with foot mechanics and provide additional support.
  3. Footwear Modification:
    • Appropriate Footwear: Wearing shoes with proper support and stability can help prevent further episodes of instability. High-top shoes may offer additional ankle support.
  4. Activity Modification:
    • During the early stages of treatment, it may be wise to avoid engaging in activities with a high risk of ankle sprains. This could include certain sports or navigating uneven terrain. Taking this precautionary measure helps protect the ankle and supports the healing process.
  5. Medication:
    • To address pain and inflammation linked with chronic ankle instability, healthcare providers may prescribe nonsteroidal anti-inflammatory drugs (NSAIDs). These medications can help manage discomfort and reduce swelling in the affected area.
  6. Injections:
    • Sometimes, corticosteroid injections may be employed to alleviate inflammation and reduce pain in cases of chronic ankle instability.


Chronic ankle instability (CAI) doesn’t have to stick around forever, and getting the right treatment can often help improve how you feel and how well your ankle works. But how much things get better can be different for each person, depending on things like how bad the instability is, what caused it, and how well the treatments work.

For lots of folks, treatments that aren’t scary, like physical therapy, exercises to make the ankle stronger, learning to feel where your body is better (that’s proprioceptive training), and using things like braces or special shoe inserts can really help. These treatments aim to make your muscles stronger, help you know where your ankle is, and overall, make your ankle more stable.


Dealing with chronic ankle instability (CAI) can get better with the right treatment, but completely fixing it might be different for each person. How well treatment works depends on things like what caused the instability, how bad the ligament damage is, and how much effort you put into rehab and preventing more problems.

Here are some ways to treat chronic ankle instability:

Non-Scary Stuff:

Physical Therapy: Doing exercises with a physical therapist can make the muscles around your ankle stronger, help you move better, and improve your balance.

Proprioceptive Training: Doing specific exercises to help you feel where your body is can stop future sprains.

Supportive Stuff:

Braces or Taping: Using things like ankle braces or special tape can give your ankle more support when you’re active.

Orthotic Devices: Inserts for your shoes can also help support your ankle and make it more stable.

More Serious Stuff:

Surgery: If your ankle is really bad or if other treatments don’t work, your doctor might talk about surgery to fix the ligaments.
