Ankle instability is a condition in which the ankle joint is prone to giving way or feeling unstable, increasing the risk of sprains and injuries. It is often caused by a previous ankle injury, such as a sprain, that did not heal properly. Here are the common causes and symptoms of ankle instability.
Common Causes of Ankle Instability
The most frequent cause of ankle instability is a previous ankle sprain, especially if the initial injury was not adequately treated or rehabilitated. When the ligaments that support the ankle are stretched or torn, they may not heal properly, leading to instability. Other causes of ankle instability include:
- Repetitive Ankle Injuries: Individuals who frequently experience ankle sprains are more likely to develop chronic ankle instability. Each subsequent injury weakens the ankle and its supporting ligaments.
- Inadequate Rehabilitation: Failing to complete a comprehensive rehabilitation program following an ankle injury can result in persistent weakness and instability.
- Structural Factors: Some individuals have anatomical factors that predispose them to ankle instability, such as high arches or a history of ligamentous laxity.
- Overuse and Microtrauma: Overuse of the ankle joint or repetitive microtrauma, such as in athletes or those with physically demanding jobs, can contribute to ankle instability over time.
Ankle instability is usually caused by repeated injuries that impact the ligaments and other structural components of the joint.
Common Symptoms of Ankle Instability
If the ankle joint is unstable, you may experience ongoing symptoms and injuries. The symptoms of ankle instability include:
- Recurrent Ankle Sprains: Individuals with ankle instability often experience recurrent ankle sprains, even during minor activities or when walking on uneven surfaces.
- Feelings of Giving Way: The ankle may feel as though it is giving way, especially on uneven terrain or when changing direction quickly. This sensation can be accompanied by fear of falling or losing balance.
- Chronic Swelling: Ongoing swelling and tenderness around the ankle joint are common symptoms of instability, as inflammation can persist due to repeated injuries.
- Pain: Pain is a frequent symptom, particularly after an episode of giving way or a new ankle injury. The pain can be sharp or dull and is often localized to the ankle joint.
- Stiffness: Ankle instability can lead to stiffness in the joint, making it difficult to move the ankle through its full range of motion.
- Weakness: Weakened ankle muscles and ligaments contribute to instability, and individuals may notice a lack of strength in their ankle, especially when attempting to support their weight or maintain balance.
- Difficulty Walking: Ankle instability can affect an individual’s gait, leading to an altered walking pattern and potential difficulty bearing weight on the affected ankle.
- Tenderness: Tenderness to the touch around the ankle joint is common, especially in the areas where ligaments may have been injured.
- Popping or Clicking Sensations: Some individuals with ankle instability report hearing popping or clicking sensations in the ankle joint when moving it.
- Difficulty with Physical Activities: Engaging in physical activities, particularly those that involve running, jumping, or rapid changes in direction, can be challenging for individuals with ankle instability due to the risk of further injury.
It is important to seek medical evaluation and treatment if you experience symptoms of ankle instability. Ignoring the condition can lead to further damage to the ankle and other injuries. One of our orthopedic specialists at Ortho Sport & Spine Physicians can assess the severity of the instability and recommend appropriate interventions, which may include physical therapy, bracing, or surgical options in some cases. Early intervention can help individuals regain stability and reduce the risk of recurrent ankle injuries. Contact one of our orthopedic centers to schedule an appointment.
