Many people do not pay attention to ankle sprains and think that they can recover in a few days. In fact, ankle sprains need timely and correct treatment, otherwise the injury will be prolonged and the ankle joint will be in a subhealthy state for a long time, with common symptoms such as local swelling of the ankle joint, soreness and pain when walking, reduced joint strength and limited range of motion, which can affect the quality of daily life to varying degrees. Rest is necessary after ankle sprain, but rest is not the whole treatment. Patients without formal treatment are two to four times more likely to re-injure the ankle than those with formal treatment. If the injury does not involve ligamentous tissues, the majority of patients with initial acute injuries can be treated satisfactorily with regular conservative treatment under the guidance of a specialist, according to the principles of ice, rest and braking, compression bandaging and elevation of the affected limb. In the acute stage, ice packs can be applied for 20 minutes each time within 12~24 hours, once every 6 hours, and then changed to hot packs for 3~5 days after 24 hours to promote the absorption of local tissue exudate as soon as possible and relieve pain. If necessary, the ankle joint can be fixed with an “8” bandage for 2~3 weeks. Conservative treatment for patients with chronic injuries is relatively slow, and the aim of treatment is to improve chronic pain and soft tissue inflammation adhesions, and to eliminate painful factors such as synovial inflammation, joint capsule contracture and ligament adhesions by minimally invasive release and decompression.
