Chronic ankle laxity is ongoing looseness and instability in the ankle joint, usually the result of one or more severe ankle sprains. Each significant sprain stretches or tears the ligaments a bit further, so the ankle loses some of its natural support — which makes it easier to sprain again, a cycle that tends to compound over time.
Recognizing it
A feeling that the ankle is loose or “gives way,” recurrent swelling, and pain, often noticeably worse than a single fresh sprain would produce. Imaging (X-ray, sometimes MRI or CT) helps confirm the extent of ligament damage.
Treatment
The first approach is the same rehab progression used for an acute ankle sprain — range of motion, resisted strengthening, then balance and agility work — alongside a supportive brace and anti-inflammatory medication as needed. What’s different here is that many people with chronic laxity benefit from continuing balance and strengthening work long-term, not just until symptoms resolve. If the ankle stays loose and unstable despite consistent rehab, surgery to reconstruct the damaged ligaments is an option worth discussing, since repeated twisting on an unstable ankle can gradually wear down the joint itself.
Rehab progression
- Mobility: towel stretch and standing calf/soleus stretches.
- Strength in every direction: resistance band work for dorsiflexion, plantarflexion, inversion, and eversion — the same four directions covered in the ankle sprain guide.
- Balance and proprioception: single-leg balance (eyes open, then closed, then on an unstable surface) is especially important here, since it’s the reflexive control — not just strength — that tends to stay deficient after repeated sprains.
Taping or bracing during sport is often recommended on an ongoing basis for a chronically unstable ankle, not just during recovery.
