Why Does My Ankle Give Out When I Walk?

Published in Ankle Instability 4 mins read

Your ankle giving out, often described as a sudden feeling of weakness, instability, or rolling, is most commonly a sign of chronic ankle instability. This condition typically arises from an incomplete recovery following an acute ankle sprain, leaving the ankle vulnerable to repeated episodes.

Understanding Ankle Instability

When your ankle "gives out," it means it suddenly buckles or feels like it's going to roll, leading to a temporary loss of balance. This sensation is particularly common in specific situations:

  • Walking on uneven surfaces: Such as trails with roots, rocks, or potholes.
  • Stepping off a curb: A seemingly simple step that can challenge ankle stability.
  • During physical activity: Especially sports that involve quick changes in direction or jumping.

The Root Cause: Incomplete Sprain Recovery

The most frequent reason for developing chronic ankle instability is an unhealed or incompletely recovered ankle sprain. An ankle sprain occurs when the tough bands of tissue that support the ankle (ligaments) are stretched or torn. If these ligaments don't heal properly, or if the surrounding muscles aren't adequately strengthened and retrained, it can leave the ankle with lasting vulnerability.

This incomplete recovery leads to two primary issues that contribute to the ankle giving out:

  1. Ligamentous Weakness: The damaged ligaments may not regain their original strength and tension, providing insufficient support to the ankle joint.
  2. Impaired Postural Control: Often referred to as poor proprioception, this means the ankle's ability to sense its position in space and react quickly to changes is compromised. Your brain struggles to receive accurate feedback, making it harder to stabilize the ankle rapidly when it's challenged.

Common Scenarios and Their Underlying Issues

Understanding when and why your ankle gives out can help identify the root cause:

Scenario Where Ankle Gives Out Underlying Reason
Walking on uneven ground Impaired postural control, ligament weakness from previous sprain
Stepping off a curb Reduced proprioception, inadequate muscle strength for sudden load changes
Quick turns or sports Chronic ankle instability due to unrecovered sprain, poor balance

Recognizing Chronic Ankle Instability

Beyond the feeling of the ankle giving out, you might experience other symptoms if you have chronic ankle instability:

  • Repeated ankle sprains: A history of multiple ankle twists or turns.
  • Persistent ankle pain or tenderness: Especially along the outside of the ankle.
  • Swelling: Intermittent or lingering swelling in the ankle.
  • Stiffness: A feeling of tightness or reduced range of motion.

Solutions and Management

Addressing chronic ankle instability often involves a combination of strategies aimed at restoring strength, balance, and stability to the ankle.

  • Physical Therapy: This is a cornerstone of recovery, focusing on:
    • Strengthening exercises: Targeting the muscles around the ankle and leg to provide better support.
    • Balance training: Using exercises like standing on one leg, wobble boards, or balance discs to improve proprioception and reaction time.
    • Range of motion exercises: To maintain flexibility and prevent stiffness.

  • Bracing or Taping: For temporary support during activities, an ankle brace or athletic tape can provide external stability and help prevent further episodes of giving out.
  • Gradual Return to Activity: It's crucial to gradually increase activity levels and avoid high-impact movements or sports until the ankle has regained sufficient strength and stability.
  • Proper Footwear: Wearing supportive shoes that fit well can help provide stability and reduce the risk of rolling your ankle.
  • Prevention of Future Sprains: Fully rehabilitating any acute ankle sprain is vital to prevent it from progressing to chronic instability. This includes following RICE (Rest, Ice, Compression, Elevation) immediately after injury and adhering to a prescribed rehabilitation program.

If you frequently experience your ankle giving out, consulting with a healthcare professional, such as an orthopedic doctor or a physical therapist, is recommended for an accurate diagnosis and a personalized treatment plan.
