Chronic ankle instability is a condition where the ankle repeatedly gives out or feels unstable, particularly during physical activity or when walking on uneven ground. It often develops after repeated ankle sprains that haven’t healed properly or were not fully rehabilitated.
The most common cause is an incomplete recovery from a previous ankle sprain. Over time, the supporting ligaments may become stretched or weakened, reducing stability. Factors like ligament laxity, poor ankle strength, or improper footwear can also contribute to ongoing instability.
Patients often report a persistent feeling that the ankle might “roll,” along with frequent swelling, tenderness, or discomfort. There may be difficulty with certain activities, such as sports or walking on uneven surfaces. Diagnosis involves a thorough physical exam, review of your injury history, and often X-rays or advanced imaging to evaluate ligament integrity and rule out joint damage.
