The best time to exercise for a fractured ankle will depend on the individual patient and their condition. If the fracture is treated conservatively, exercise is usually started when the fracture is clinically healed. For surgical treatment, exercise can usually be performed 3 weeks after surgery for patients with less severe fractures, while severe patients need to be delayed until after 6~8 weeks. 1. Individual situation: In similar cases, young people with good physical condition can usually start exercise 3 weeks after surgery. For elderly patients with osteoporosis, exercise needs to be delayed to 6~8 weeks later. 2. Fracture severity: patients with mild fracture can start exercise 3 weeks after surgery, while those with severe fracture usually start functional exercise 6~8 weeks after surgery. 3. Fracture recovery: For patients with good fracture recovery, exercise can be started 3 weeks after surgery after reaching the standard of exercise, while patients with poor recovery need to wait for the fracture to recover. It is recommended that patients with ankle fracture should consult a doctor in time and under the guidance of a professional doctor, do not exercise blindly to avoid adverse consequences.
