Ankle sprains are one of the most common recurrent injuries, with many people experiencing a sprained ankle 7-18 times in their lifetime. Our team of experts wants to guide you through understanding and preventing these recurring ankle sprains, also known as chronic ankle instability. This article is worth reading if you want to learn how to fix chronic ankle instability and reduce the chances of future ankle injuries.
What is Chronic Ankle Instability?
Chronic ankle instability is a condition where the ankle may repeatedly “give way” or feel unstable, leading to recurrent ankle sprain injuries. It often develops after repeated ankle sprains, where the initial injury fails to heal properly. The ankle becomes more susceptible to sprains due to damaged ligaments and decreased range of motion.
Anatomy of the Ankle
The ankle joint is a complex structure involving bones, ligaments, and muscles. The lateral ankle is particularly vulnerable to injury, with the anterior talofibular ligament being the most commonly injured ligament during a sprained ankle. When chronic ankle instability occurs, the damaged ligaments and muscles around the ankle can’t provide adequate support, making the ankle more prone to recurrent ankle sprains.
What Causes Recurrent Ankle Sprains?
Recurrent ankle sprains are a common issue that many people face, often due to a combination of factors. Understanding these causes can help you take preventive measures to avoid further injury.
Inadequate Rehabilitation
One of the primary reasons for recurrent ankle sprains is inadequate rehabilitation following an initial injury. When you sprain your ankle, the ligaments and muscles around the joint are weakened. Without proper rehabilitation, these structures may not fully heal or regain their strength, leaving the ankle susceptible to further injury. A comprehensive rehabilitation program should include strengthening exercises, range-of-motion exercises, and proprioceptive training to improve balance and stability. Skipping or rushing through this phase increases the risk of developing chronic ankle instability, where the ankle may feel “unstable” or “give way” frequently.
Improper Footwear
The shoes you wear play a crucial role in supporting your feet and ankles during daily activities. Wearing footwear that lacks proper support or stability can increase the strain on your ankle ligaments and muscles, making them more prone to sprains. High heels, flip-flops, and worn-out shoes are some examples of footwear that can contribute to ankle instability. It’s important to choose shoes that fit well, provide adequate ankle support, and are appropriate for the activity you’re engaging in. Investing in quality footwear can significantly reduce the risk of recurrent ankle sprains.
Muscle Weakness
Weakness in the muscles around the ankle joint is another common cause of recurrent ankle sprains. These muscles play a crucial role in supporting and stabilizing the ankle during movement. If they’re weak, they can’t provide adequate support to the joint, making it more susceptible to injuries. Muscle weakness can result from a sedentary lifestyle, lack of exercise, or not targeting these specific muscles during workouts. Incorporating strength training exercises that target the calf, shin, and foot muscles can help improve muscle strength and stability around the ankle, reducing the risk of sprains.
All in all recurrent ankle sprains can be caused by inadequate rehabilitation, improper footwear, and muscle weakness. Addressing these factors through proper rehabilitation, wearing supportive footwear, and strengthening the muscles around the ankle can significantly reduce the risk of further injury and help you maintain ankle stability.
Risk Factors for Ankle Injuries
- Previous Ankle Injury: A history of ankle sprains increases the risk of recurrent ankle sprains.
- Foot Shape: Certain foot shapes make you prone to ankle instability.
- Sports Participation: High-impact sports or activities with frequent direction changes can lead to ankle injuries.
Symptoms of Chronic Ankle Instability
Common Symptoms:
- Ankle pain or tenderness
- Swelling around the ankle
- Feeling of instability or “giving way”
Rare Symptoms:
- Chronic pain
- Limited range of motion
- Persistent swelling
Diagnosis of Recurrent Ankle Sprains
Chronic ankle instability is diagnosed through a combination of:
- Initial Diagnosis: Medical history and physical examination will be done by an orthopaedic doctor to assess the ankle’s stability and range of motion.
- Clinical Examination: Specific tests to evaluate ligament integrity and ankle stability.
- Other Potential Examinations: MRI or X-ray may be used to rule out other injuries or assess the severity of ligament damage.
Treatment Options for Ankle Sprains
When it comes to treating ankle sprains, early and appropriate intervention can make a significant difference in recovery time and long-term ankle health. Let’s delve deeper into the treatment options available for ankle sprains.
Common Treatments
R.I.C.E (Rest, Ice, Compression, Elevation)
The R.I.C.E protocol is a widely recommended initial treatment for acute ankle sprains.
- Rest: It’s essential to give your injured ankle adequate rest to allow the ligaments to heal. Avoid putting weight on the injured ankle and limit activities that exacerbate the pain.
- Ice: Applying ice to the injured ankle helps reduce swelling and pain. Use an ice pack wrapped in a cloth and apply it to the affected area for 15-20 minutes every 2-3 hours during the initial 48 hours post-injury.
- Compression: Wrapping the ankle with a compression bandage can help reduce swelling and provide support to the injured ligaments. Ensure that the bandage is snug but not too tight to avoid cutting off circulation.
- Elevation: Elevating your ankle above the level of your heart can help reduce swelling. Prop your ankle up on a pillow or cushion whenever possible, especially during the first few days post-injury.
Physiotherapy
Physiotherapy plays a crucial role in the rehabilitation process after an ankle sprain.
- Strengthening Exercises: Physiotherapists prescribe specific exercises to strengthen the muscles around the ankle joint, improving its stability. These exercises often include calf raises, ankle dorsiflexion/plantarflexion exercises, and resistance band exercises.
- Range of Motion Exercises: Gentle exercises to improve the ankle’s range of motion are essential for restoring normal joint function. This may include ankle circles, ankle alphabet exercises, and passive stretching.
- Proprioceptive Training: Proprioception refers to the body’s ability to sense its position in space. Proprioceptive training exercises, such as balance exercises on a wobble board or foam pad, help improve ankle stability and reduce the risk of recurrent ankle sprains.
Ankle Brace
An ankle brace or support can provide external support to the injured ankle, reducing the risk of recurrent ankle sprains.
- Types of Ankle Braces: There are various types of ankle braces available, including lace-up braces, stirrup braces, and hinged braces. The type of brace recommended depends on the severity of the sprain and the individual’s activity level.
- Wearing Schedule: Initially, you may need to wear the ankle brace all the time to provide maximum support. As the ankle heals and becomes stronger, you can gradually reduce the wearing time.
- Custom Orthotics: In some cases, custom orthotic devices may be prescribed to provide additional support and correct any biomechanical issues contributing to ankle instability.
Rare Treatments
Surgery
In severe cases of ankle sprains where there is significant ligament damage or if conservative treatments fail to provide relief, surgical intervention may be necessary.
- Arthroscopy: Minimally invasive arthroscopic surgery may be performed to repair the damaged ligaments and remove any loose fragments of tissue or bone.
- Open Surgery: In cases of severe ligament tears or complete ligament ruptures, open surgery may be required to reconstruct the ligament using grafts from other tendons or ligaments.
- Recovery and Rehabilitation: Following surgery, a comprehensive rehabilitation program supervised by a physiotherapist is crucial to regain strength, flexibility, and function of the ankle joint. This may include a combination of strengthening exercises, range of motion exercises, and proprioceptive training.
Complications of Chronic Ankle Instability
Frequent Complications:
- Recurrent Ankle Sprains: Recurrent ankle instability leading to recurrent injuries.
- Chronic Pain: Persistent ankle pain despite treatment.
Occasional Complications:
- Ankle Fracture: Increased risk due to weakened ligaments.
- Arthritis: Development of arthritis in the ankle joint over time.
Prevention of Recurrent Ankle Injuries
- Proper Rehabilitation: Complete a full physiotherapy program after an ankle sprain.
- Wear Supportive Footwear: Shoes with good ankle support and stability.
- Neuromuscular Training: Exercises to improve muscle strength and coordination around the ankle.
How to Work Out with Chronic Ankle Instability
While it’s important to avoid activities that aggravate your ankle, you can still work on strengthening other muscles around your ankle. Focus on exercises that target the calf, shin, and foot muscles to provide additional support to the injured ankle.
Managing Ankle Sprains
- Regular Exercise: Continue with strengthening exercises and activities to maintain ankle stability.
- Pain Management: Use anti-inflammatory drugs as prescribed to manage pain and swelling.
- Regular Check-ups: Visit your foot and ankle surgeon for regular follow-ups to monitor your ankle’s progress.
