Chronic Ankle Instability Treatment
at Foot Foundation

If your ankle keeps “giving way,” it may be chronic ankle instability from repeated sprains.

At Foot Foundation, we provide specialist care combining strengthening, balance training, orthotics, and rehabilitation to restore confidence and prevent further sprains.

What is Chronic Ankle Instability?

Chronic ankle instability (CAI) is a condition where the ankle repeatedly “gives way” following one or more ankle sprains. It results from a combination of ligament laxity, proprioceptive deficits, and muscular weakness, leading to recurrent sprains, persistent instability, and long-term joint changes.

Without specialist care, CAI can progress to early ankle arthritis, cartilage injury (osteochondral lesions), and permanent loss of stability.

At Foot Foundation, we provide specialist-level assessment and rehabilitation for CAI, addressing both the structural ligament damage and the neuromuscular deficits that cause ongoing problems.

Causes & Risk Factors

  • History of ankle sprains (most common cause)

  • Incomplete or poor rehabilitation following an acute sprain

  • Generalised ligament laxity or hypermobility

  • Weak peroneal muscles or poor balance

  • Foot and ankle biomechanics (excessive pronation, cavus foot)

  • High-risk sports (netball, basketball, football, rugby, trail running)

  • Poor footwear lacking lateral support

  • Walking or training on uneven ground

Treatment at Foot Foundation

  • Balance and proprioception training – essential for restoring joint control

  • Strengthening programs – peroneals, calf, and intrinsic foot muscles

  • Custom orthotics – improve biomechanics and reduce recurrence risk

  • Functional bracing or strapping – for short-term support in sport

  • Manual therapy – mobilisation and soft tissue release

  • Shockwave therapy – in cases of chronic ligament pain or scar tissue

  • Return-to-sport rehabilitation – progressive, sport-specific drills

  • Referral to orthopaedics – if surgical ligament reconstruction is required in severe cases

Symptoms

  • Recurrent ankle sprains, often during sport or daily activity

  • Sensation of ankle “giving way” or instability

  • Ongoing ankle pain, swelling, or stiffness after activity

  • Difficulty with balance and uneven surfaces

  • Reduced confidence in ankle stability, leading to activity avoidance

Diagnosis

At Foot Foundation, diagnosis is made through:

  • Detailed injury history (number of sprains, mechanism of injury)

  • Ligament stability testing (ATFL, CFL, PTFL)

  • Functional strength and balance testing

  • Gait and biomechanical assessment

  • Ultrasound or MRI if structural damage or cartilage injury is suspected

Podiatrist pricing and availability

Pricing for Chronic Ankle Instability assessment and treatment can vary depending on your consultation, the severity of your instability, the treatment approach recommended, and whether ongoing podiatry or rehabilitation care is required.

Your Foot Foundation clinician will assess your ankle stability, movement patterns, strength, and contributing biomechanical factors, then explain the most appropriate treatment plan based on your symptoms, activity level, and recovery goals.

Chronic Ankle Instability -
Frequently Asked Questions

What is Chronic Ankle Instability?

Chronic Ankle Instability is a condition where the ankle repeatedly gives way following one or more sprains. It develops when ligament laxity, weakness, and poor neuromuscular control leave the ankle unable to stabilise properly.

Why does my ankle keep rolling after a sprain?

The most common reason is incomplete recovery after an ankle sprain. If the ligaments heal in a weakened or lengthened state and rehabilitation is not fully completed, the ankle can remain unstable and more likely to roll again.

How is Chronic Ankle Instability different from a single ankle sprain?

A single ankle sprain is an acute injury to the ligaments. Chronic Ankle Instability is a longer-term condition where the ankle continues to feel unstable or repeatedly gives way because strength, balance, and ligament support have not fully recovered.

Can Chronic Ankle Instability cause long-term problems?

Yes. If left untreated, Chronic Ankle Instability can increase the risk of repeated sprains, cartilage damage inside the ankle joint, and early ankle arthritis due to ongoing joint trauma.

How long does it take to recover from Chronic Ankle Instability?

With structured rehabilitation, many patients improve within 8 to 12 weeks. More severe or long-standing instability can take longer, and some cases may need surgical opinion if conservative treatment is not enough.

What is the best treatment for Chronic Ankle Instability?

The most effective treatment usually combines balance and proprioception training, strengthening of the ankle stabilisers, orthotics where needed, and functional bracing or strapping during higher-risk activity.

Do orthotics help with Chronic Ankle Instability?

Yes. Orthotics can help improve foot biomechanics, reduce abnormal movement patterns, and improve ankle stability, especially when used alongside strengthening and balance rehabilitation.

Do I need surgery for Chronic Ankle Instability?

Most patients improve with conservative care. Surgery may be considered if instability continues despite good rehabilitation or if there is severe ligament damage with ongoing mechanical laxity.

Can I play sport with Chronic Ankle Instability?

Yes, but it should be managed properly. Functional bracing, strapping, strengthening, and a graded return-to-sport programme can help reduce the risk of further injury.

When should I see a podiatrist for ankle instability?

If your ankle gives way repeatedly, you have had two or more sprains in a year, or you feel ongoing weakness or instability, it is a good idea to seek specialist assessment early.

Our approach to Chronic Ankle Instability

At Foot Foundation, our approach to Chronic Ankle Instability begins with a thorough assessment to identify the extent of ligament laxity, weakness, balance deficits, and biomechanical factors contributing to your instability.

Once the diagnosis is confirmed, we create a personalised treatment plan focused on restoring stability, improving strength and joint control, and reducing the risk of further sprains. Depending on your presentation, treatment may include balance and proprioception training, strengthening programmes, custom orthotics, functional bracing or strapping, manual therapy, shockwave therapy for persistent ligament pain, and a structured return-to-sport rehabilitation plan where appropriate. In more severe cases, we may also recommend imaging or referral for orthopaedic opinion.

Our goal is not only to improve ankle stability now, but also to reduce long-term joint damage, improve confidence in movement, and help you return to daily activity and sport more safely.
