Chronic Ankle Instability (CAI)
Chronic Ankle Instability is a condition where the outer side of the ankle frequently gives way, especially during walking, running, or standing on uneven surfaces. This often occurs after repeated ankle sprains or an ankle injury that has not healed properly.
If you find yourself frequently twisting your ankle or feeling that your ankle is weak or unstable, it may be more than just a simple sprain; you could be experiencing chronic ankle instability.
What Causes Chronic Ankle Instability?
Chronic ankle instability usually develops after:
- Recurrent ankle sprains
- Inadequate rehabilitation after an initial sprain
- Ligament damage or weakening over time
- Poor balance or proprioception
- Structural foot issues such as high arches
Common Symptoms
- Frequent ankle rolling or giving way
- Persistent ankle pain or tenderness
- Swelling after activity
- Feeling of weakness or unsteadiness in the ankle
- Difficulty walking on uneven surfaces or wearing certain footwear
Podiatric Assessment for Chronic Ankle Instability
When you visit a podiatrist for ankle instability, a thorough assessment is essential to determine the cause and develop an effective treatment plan.
1. Medical & Injury History
- Frequency and history of ankle sprains
- Level of instability or “giving way”
- Type of physical activity
2. Physical Examination
- Testing ligament laxity (e.g. anterior drawer test, talar tilt test)
- Assessment of swelling, tenderness, and muscle strength
- Gait analysis and weight-bearing examination
3. Balance and Proprioception Testing
- Evaluating your ability to control movement and respond to balance challenges
4. Diagnostic Imaging
- Used as needed to assess ligament damage or joint instability
Treatment Options for Chronic Ankle Instability
Managing chronic ankle instability focuses on improving ankle strength, joint stability, and preventing future injuries.
Non-Surgical Treatments
- Rehabilitation & Strengthening Programs: Targeted physiotherapy to restore ankle strength, stability, and proprioception
- Ankle Bracing or Taping: Provides external support during physical activity or daily movement
- Custom Foot Orthotics: Designed to correct biomechanical imbalances that may contribute to instability
- Balance Training Exercises: To retrain muscles and improve joint control
- Anti-inflammatory Medications: To manage pain and swelling as needed
Surgical Intervention
If conservative treatments fail, surgery may be recommended to:
- Repair or reconstruct damaged ligaments
- Address structural abnormalities in the foot or ankle
When to See a Podiatrist
If you’ve had multiple ankle sprains, feel your ankle giving out regularly, or experience ongoing pain and weakness, it’s important to seek professional evaluation. Chronic ankle instability can worsen over time and increase your risk of long-term joint damage or arthritis if left untreated.
