The total recovery time for full use of an ankle after surgery to repair an ankle fracture is 12 months, according to Kaiser Permanente. This includes the time spent wearing a cast, receiving physical therapy and returning the ankle to pre-fracture functionality.
Patients who receive an ankle surgery can expect to remain in a cast for as long as eight weeks. After two weeks, the patient receives a below-the-knee cast and begins to add weight to the ankle. The cast removal occurs six to eight weeks after surgery, and the hardware imbedded in the knee receives a checkup at approximately 12 weeks following the surgery, explains Kaiser Permanente.
