Chronic Ankle Instability  Treatment Adelaide

Ankle Pain Physiotherapy St Marys

Does your ankle keep rolling, even on flat ground? Do you feel like it could give way at any moment, or find yourself taping it “just in case”? Chronic ankle instability is common after an ankle sprain, especially if the first injury wasn’t fully rehabbed. It can knock your confidence and keep you from playing sport or moving freely. At Active Balance, we focus on rebuilding strength, balance and control in your ankle so it feels stable and reliable again.

What Is Chronic Ankle Instability?

Chronic ankle instability (CAI) is a condition where the ankle repeatedly gives way or rolls, usually on the outside. It most often develops after one or more lateral ankle sprains.

When you sprain your ankle, the ligaments on the outside of the ankle are stretched or torn. Up to 40% of people go on to develop ongoing instability after a sprain. This is usually due to a combination of:

  • Mechanical instability, where the ligaments have healed in a stretched or weakened position and provide less support
  • Functional instability, where the ankle’s balance, joint awareness (proprioception) and muscle reactions have been affected by the injury

Most cases involve both, and both respond well to targeted rehab.

Contributing Factors & Causes

  • Previous ankle sprains, which is the biggest risk factor
  • Incomplete rehab after an earlier injury

  • Reduced ankle mobility, especially after a sprain
  • Returning to sport too soon
  • Uneven surfaces and high-risk sports

Symptoms & Signs

  • Ankle repeatedly rolling or giving way
  • A feeling that the ankle is weak or unstable
  • Recurring sprains, sometimes from small missteps
  • Ongoing pain or aching on the outside of the ankle

How Physiotherapy Can Help Manage Chronic Ankle Instability?

Physiotherapy is the first-line treatment for chronic ankle instability, and most people improve without needing surgery.

  • A thorough assessment looks at your ligament stability, strength, balance, mobility and movement patterns, and rules out other injuries that may be adding to your symptoms.
  • Balance and proprioception training is the cornerstone of treatment. We progress from simple balance exercises to more challenging, sport-specific drills, retraining your ankle to react quickly and stay stable.
  • Strengthening targets the peroneals, calf, foot muscles and hips to improve support and control around the ankle.
  • Mobility work and hands-on treatment, including joint mobilisation and soft tissue work, can restore lost ankle movement and ease stiffness.
  • Hopping, landing and agility training prepare your ankle for the demands of your sport, with drills progressed as your control improves.
  • Taping and bracing can provide extra support while you’re rebuilding strength and during return to sport.
  • Return to sport testing helps make sure your ankle is ready before you return to full training and games, reducing your risk of another sprain.

How Massage & Myotherapy Can Help

Repeated ankle sprains and altered movement often lead to tension in the calves, shins and feet. Remedial massage and myotherapy can ease this tightness, improve comfort, and support your movement.

Our massage and myotherapy team works with your physio so soft tissue treatment complements your rehab program.

When to Seek Further Medical Advice

Most people with chronic ankle instability improve with physiotherapy. However, some injuries need further investigation. See a doctor or get a prompt assessment if you have:

  • Severe pain, swelling or bruising after a sprain, or being unable to put weight on your foot, which may indicate a fracture
  • Pain higher up between the shin bones, which may indicate a high ankle sprain (syndesmosis injury)
  • Deep, aching ankle pain with ongoing swelling, catching or locking, which may indicate a cartilage injury
  • Pain, clicking or snapping behind the outer ankle bone, which may indicate a peroneal tendon injury
  • Numbness, tingling or weakness in the foot
  • Ongoing instability despite consistent, well-structured rehab
  • If any of these apply, we’ll identify them at your assessment and refer you for imaging or to an orthopaedic specialist.

Prognosis

The outlook for chronic ankle instability is good with the right rehab.

  • Many people notice improvement within six to twelve weeks of consistent balance and strength training
  • Continuing a maintenance program helps reduce the risk of further sprains
  • For people with significant ligament laxity who don’t improve with rehab, surgical repair may be considered. If surgery is needed, a structured rehab program afterwards is essential

The most common reason for ongoing problems is stopping rehab once the pain settles, before balance and strength have fully returned.

Frequently Asked Questions

Q: Did I cause this by not rehabbing my sprain properly?
Not necessarily, and it’s a really common situation. Many people are told to just rest a sprain and are never given a rehab program. Some ankles also have more ligament damage than others. The good news is it’s not too late. Even years after the original sprain, targeted rehab can make a big difference.

Q: Should I keep taping or bracing my ankle?
Taping and bracing can be helpful, especially during sport while you’re rebuilding strength. However, they shouldn’t replace rehab. The goal is for your ankle to feel stable on its own, with tape or a brace as extra support if needed.

Q: Do I need a scan?
Not always. Chronic ankle instability is usually diagnosed through your history and a physical assessment. An X-ray, ultrasound or MRI may be recommended if another injury is suspected or you aren’t improving as expected.

Q: Will I need surgery?
Most people don’t. Surgery is usually only considered when there’s significant ligament laxity and symptoms haven’t improved after a good trial of rehab.

Q: Can I keep playing sport?
Often, yes, with some modifications, and with taping or bracing while you rebuild. Your physio will help you work out what’s safe and guide your return to full sport.
