Six months after ankle fracture surgery, you can run if the fracture end is in good condition. If the fracture heals poorly or even has delayed healing, then running should be delayed. Since the foot is a weight-bearing part, weight-bearing should be avoided in the early period after ankle fracture to avoid displacement of the fracture. Generally speaking, 4-6 weeks after the reset, the bone scab can be formed, and the fracture is relatively stable, so you can start to walk partially with weight bearing with the help of auxiliary tools, such as crutches. After ankle fracture surgery, it usually takes 10-12 weeks to achieve basic bone healing, the fracture line disappears, and the fracture is able to bear all the weight, so you can gradually take off the crutches and walk independently, but at this time you should avoid strenuous exercise. After another 8-12 weeks of rehabilitation, that is, six months after the ankle fracture surgery, the muscle strength is gradually recovered and the bone is completely healed, at this time you can start running. If the displacement of comminuted ankle fracture is serious or the elderly osteoporosis patients, if the fracture healing is not good or even delayed healing phenomenon half a year after the operation, then running time should be delayed, activity time should be based on the specific conditions of consulting a specialist to determine.
