Ankle laxity can be treated by conservative treatment, surgical treatment and minimally invasive surgery. 1. Conservative treatment: mainly limiting activities, the foot and ankle can be treated conservatively by ankle immobilization, such as plaster external immobilization, ankle brace immobilization and other conservative treatments. 2. Surgery: If the ligaments are still lax after 4 to 6 weeks of immobilization in a plaster or ankle brace and a normal life cannot be achieved, then surgical treatment is needed to tighten and suture the ligaments and strengthen the immobilization with anchors. 3. Minimally invasive surgery: Minimally invasive surgery involves arthroscopic tightening of loose ligaments or reinforcement with artificial ligaments or tendons. When the patient has a loose ankle, he should go to the hospital in time, and under the guidance of a professional doctor, choose the targeted treatment method according to the actual situation.
