The recovery time of ankle fracture usually takes three months, and the recovery process includes cast braking, cast removal and clinical healing, as follows: 1. Cast braking: In the early stage of fracture, cast braking should be applied, and the braking time is about six weeks, during which the lower limb must be elevated, which is conducive to the decreasing of limb swelling, and the isometric functional training of the foot and ankle muscles should be carried out. 2. Cast removal: At If it is clear that there is continuous bone scab at the fracture end, it means that the fracture has the initial stability, so you can remove the external cast and gradually put weight on the ground with the support of double crutches. If the fracture line is blurred, disappears and the local symptoms disappear, it means the fracture has reached clinical healing, so you can abandon the crutches and walk with full weight.
