No surgery required. Go conservative . Walking Cast for 6 weeks .

Hello, you may not need surgery if this is an acute tear. A recent one. However, it definitely needs immobilization for a few weeks. May be 3 to 4 weeks. Surgery is usually required for those who have chronic pain and instability from the ligament tear. This happens because the ligament had failed to heal. There are a few  exceptions which cannot be addressed in detail here.  These mainly involve injuries to associated structures in and around the ankle joint. Please take a formal consultation from an orthopedic surgeon or a sports injuries surgeon. Hope this helps.
