Chronic ankle instability

An ankle that keeps giving way usually traces back to a sprain that healed loose, and every repeat sprain does a little more damage to the joint surface. Rebuilding the stability is what prevents arthritis later.

What's Involved

Stability testing — Examination of the lateral ligaments and assessment of proprioception.
Imaging — X-ray and ultrasound to rule out fracture and grade ligament damage.
Rehabilitation or repair — Bracing and balance training first, ligament reconstruction if it fails.

When to Come In

Repeated rolling — Turning the ankle on uneven ground or even flat surfaces.
A feeling of giving way — Lack of confidence on stairs, kerbs, or slopes.
Persistent swelling — An ankle that never fully settles between episodes.
