Most ankle sprains heal fully in a few weeks. But if the ankle keeps giving way, feels unsteady on uneven ground or swells again and again, the ligaments on the outer side may have healed loose. This is called chronic lateral ankle instability.
Why does it matter?
An ankle that keeps rolling can damage the cartilage inside the joint, injure tendons, and in time lead to arthritis. Treating it early protects the joint.
How is it assessed?
Examination checks how loose the joint is and whether there is a high-arched foot or other cause. X-rays and sometimes an MRI look at the ligaments, the tendons and the cartilage.
What treatment is available?
- Physiotherapy and bracing: strengthening and balance training are the first step for most people.
- Ankle arthroscopy: a keyhole look inside the joint can treat cartilage damage, scar tissue and impingement at the same time.
- Ligament repair (Broström): the stretched ligament is tightened and reattached.
- Anatomic reconstruction: when the ligament is too weak, it is rebuilt with a graft.
- Percutaneous reconstruction: smaller-incision techniques may suit selected patients.
The right option depends on your ankle, your activity level and your goals, and is agreed with you after assessment.
