Chronic ankle instability (CAI) is a condition that not only hampers your daily activities, but also impacts athletic performance significantly. CAI is exactly what it sounds like—ankle instability which occurs chronically, or over a considerable length of time. This can arise from repetitive ankle injuries, often because of inadequate healing from sprains. This leads to weakened or damaged ligaments. It can also occur from hypermobility disorders, including Ehlers-Danlos Syndromes (EDS). Chronic ankle instability doesn’t just rob you of your confidence during movement. It also brings a constant worry of reinjury and can affect both physical health and mental wellbeing. This post will review various causes of CAI, different treatment options, and ways to help manage your CAI.

Understanding the Causes of Chronic Ankle Instability
Understanding the cause of CAI makes it easier to determine your course of action when it comes to managing your ankle instability. Luckily, ankle instabilities have to be treated in similar manners, regardless of the cause of it. At the heart lies poor ligament stability and possibly even ligament damage.
Ankle health relies heavily on ankle stability and the strength of the supporting musculature. CAI can arise from repetitive ankle injuries. This leads to weakened or damaged ligaments. Poor rehab or lack of rehab after injury can also lead to CAI. EDS, a hypermobility disorder, can also be a cause of chronic ankle instability.
Without proper physical therapy for the ankle after injury, weakened or poorly healed ligaments can struggle to support the joint. This leads to increased susceptibility to sprains and a frustrating cycle of repetitive injury. This narrative is all too common among athletes and individuals leading an active lifestyle. Recognizing the critical role early and effective intervention can be pivotal in breaking the cycle of CAI.
Identifying the Symptoms of CAI
The ankle ligaments are designed to support and stabilize the ankle throughout its normal range of motion. When the ankle has too much range of motion, the ligaments have to work even more to stabilize. If you have already suffered from multiple ankle sprains, the ligaments can sometimes become “loose” or overlengthened. Because ligaments are non-contractile soft tissue, they cannot contract and “tighten up.” At this point, training the muscles of the ankle and foot to become stronger and provide the support that the ankle ligaments are lacking is paramount.
Symptoms of ankle instability are multiple ankle sprains or a sensation of the ankle feeling like it wants to roll. These symptoms don’t just affect daily activities. If you do not seek treatment, over time, the need for surgery after multiple injuries increases.
Importance of Early Diagnosis
Ensuring ankle sprains receive the care they need after injury, the easier the road to recovery becomes. Ankle sprains, if left untreated, can escalate into chronic ankle instability. Now, this does not mean that every single time an ankle is sprained that it will develop chronic ankle instability. But every subsequent ankle sprain that is sustained on the same side puts you closer and closer to developing CAI. If you suffer from multiple ankle sprains and feel like it is easy for you to roll your ankles, then you most likely have CAI.
One of the best things you can do is take care of your sprained ankle initially when the injury happens. This reduces your chances of developing any subsequent issues. You’ll want to work on strengthening the stabilizers of the foot and ankle through various balance exercises. Also, strengthening the intrinsic muscles of the foot and calf will be important. If you are uncertain with how to properly rehab your ankle back from an injury, seeking help from a physical therapist can drastically help.
Conservative Treatment Options for Chronic Ankle Instability
The pathway to managing ankle instability varies greatly from on individual to another. Most treatment will involve conservative treatment, but there are those few cases that will require a surgical option. While most minor ankle sprains will heal on their own, more serious injuries and CAI should follow a rehabilitation plan in physical therapy for the best outcomes. Embracing a proactive approach to treatment and prevention is key to overcoming chronic ankle instability.
Physical Therapy and Chronic Ankle Instability
Physical therapy plays a pivotal role in navigating through ankle sprains and CAI. It focuses on restoring ankle mobility, strengthening the muscles of the foot and ankle, as well as re-establishing balance and proprioceptive feedback. For athletes returning to sport, the ankle needs to withstand the forces involved with running, jumping, and cutting. The foot and ankle complex needs to be able to handle the forces involved with these types of quick reaction movements (and quite literally, not buckle under pressure). For this, having a watchful eye under a physical therapist is paramount for returning to your usual game play and reducing any risk of reinjury.
Exercises should focus on strengthening, stabilizing, and balance training. The goal is to enhance overall joint stability. Your joints get their inherent structural stability from the ligaments. When those ligaments are injured or damaged, you need to strengthen the muscles around the joint to them provide the stability that is lacking from the ligaments. You also lose some proprioceptive ability every time you roll your ankle. Proprioception is a fancy word that means you know where you are in space. This is key to balance. You need to retrain your ankle to be able to tell where it is at in space so you have better balance and help prevent reinjury in the future. You do this through many different balancing exercises.
Home Management Strategies
Home management strategies will be crucial whether you have a mild injury or decide to have physical therapy. Physical therapists utilize home programs to supplement what they can do with you in clinic. And if you don’t choose to have physical therapy, working on your own home exercises is even more important.
Dealing with chronic ankle instability is more than a minor inconvenience. It’s a recurring condition that can significantly impact your day, from simple tasks to your athletic performance. However, the journey towards better ankle health and stability doesn’t necessarily demand constant medical intervention, PT included. Surprisingly, a substantial part of managing CAI successfully boils down to home management strategies. Let’s dive into some actionable ways you can take charge of your CAI from the comfort of your home.
- Ankle Strengthening Exercises: Reinforcing the muscles around your ankle not only accelerates recovery from ligament injury, but also fortifies your ankles against future sprains and strains. Consider incorporating exercises like double limb or single limb heel raises. 4-way resisted ankle exercises are also useful, especially in early stage recovery.
- Proximal Leg Strengthening Exercises: Don’t forget all of the other muscles of your leg! Just because you injured your ankle doesn’t mean you get to forget about your quads, hamstrings, and glutes. All of these muscles are used when you stand from a chair, go up and down stairs, and when you run. If you injure you ankle and are hobbling around, then guess what…the muscles further up your leg are getting weaker from not using them, too. Fun fact: working on your glutes will help with balance too!
- Proprioception/Balance Training: Enhancing your body’s awareness of ankle positioning can greatly reduce the likelihood of repetitive injuries. Simple balance training, like standing on one foot or using a balance board, can significantly improve your proprioception.
By embracing these practical home management strategies, you’re taking a proactive role in preventing future ankle injuries, setting the stage for a more active lifestyle.
A Little Extra Support (Footwear and Braces)
Aside from PT and exercises, supportive footwear and ankle braces can provide additional support and minimize the risk of injury. Wearing the right footwear when doing things like hiking can help stabilize your ankles. If you are returning to sport after injury and your ankle needs a little extra support, ankle braces can provide that support until your ankle is fully healed and ready to not rely on the brace.
For cases where conservative treatment fails to provide the necessary relief and stability, ankle surgery may be recommended. This option is typically considered for individuals with significant ligament damage. Post-surgery, a comprehensive rehabilitation plan is vital to ensure a successful recovery and to restore optimal ankle mobility. Physical therapy is a requirement after surgery if you are looking for optimal recovery.
The Role of Surgery in Chronic Ankle Instability
When you’ve tried all other conservative options, surgery may become a path worth considering. This option is typically reserved for those experiencing significant ligament damage which often involves frequent ankle sprains due to poor structural support of the ankle. The types of surgical procedures will vary depending on what specific problem you are dealing with. You have to look at which ligament(s) is/are damaged and which option will provide the most sound structural support for your ankle. Your surgeon can help determine which option is right for you.
Post-surgery, the expectation is a return to a more stable, active lifestyle free from the constant worry of chronic instability. However, surgery is not a silver bullet. It requires a commitment to a rehabilitation program with physical therapy. The surgery fixes the structural problems related to your instability, but it does not retrain the muscles to provide support or gain their strength back. This is why physical therapy is crucial post-surgery.
Preventing Reinjury
When it comes to preventing reinjury, you’ll want to take the principles you applied during your rehabilitation process and continue them beyond your recovery. You might not have to perform ankle strengthening and balance exercises as frequently as you did during rehab. But, you don’t want to forget about these exercises completely once you are fully recovered.
Try working a few balance exercises into your weekly gym routine. You could add in a few ankle strengthening exercises during your leg day. Or, picking one day per week to focus on your more advanced ankle exercises from your rehabilitation program will ensure you give your foot and ankle the moment it deserves. By mindfully embedding these preventive measures, you are equipping your body with the necessary tools to help prevent reinjury and maintain your ankle health.
