What is the first treatment for chronic ankle instability?

Chronic ankle instability means the ankle repeatedly gives way or feels unreliable, often after one or more sprains. Rehabilitation targets the muscles around the ankle and the body's ability to sense joint position. A therapist may work on range of movement, calf and foot strength, single-leg control and gradual return to walking, work or sport.

An ankle brace or taping may be suggested during activities while control improves. The programme is adjusted if pain, swelling or balance changes. Improvement is usually built through repeated practice rather than a single session.

Arrange an assessment with a physiotherapist who can check ankle movement, strength, balance and the way you walk. Follow the home exercises at the prescribed level, wear supportive footwear and avoid activities that repeatedly cause the ankle to roll. Do not force exercises through sharp pain or marked swelling.

If instability continues despite a well-supervised rehabilitation plan, an orthopaedic clinician may discuss [Ankle Ligament Reconstruction](/treatments/sports-and-arthroscopic-surgery/ankle-ligament-reconstruction/).

Seek urgent assessment after an ankle injury if the foot looks deformed, you cannot bear weight, numbness develops, the foot becomes unusually cold or pale, or swelling and pain are severe. Arrange a clinical review for repeated giving-way, persistent swelling or pain that is not settling, because another injury or a cartilage problem may need assessment.

Ask whether your ankle needs imaging, which exercises are safe now, whether a brace is suitable for your activities, and how progress will be measured before returning to running or pivoting sports.
