Habitual sprain is a sprain that occurs repeatedly in the same location. If the ankle sprain is not treated promptly or not completely healed, it can lead to habitual ankle sprain and the patient will have pain, swelling and limited movement of the ankle joint. Taking an MRI can reveal that the medial collateral ligament and lateral collateral ligament of the ankle joint become elongated, or a severe rupture occurs, and the stability of the ankle joint decreases, which can lead to habitual ankle sprains in daily life. Surgery is usually needed to restore the integrity and continuity of the ligaments, improve the stability of the joint and avoid habitual sprains. You should also strengthen the muscle strength and intensity training around the joint to prevent sprains from occurring.
