The ankle fracture is still painful after three years. In this case, the following reasons should be considered: First, the fracture displacement is more obvious when the ankle fracture is fractured, and the fracture line involves the joint surface. When the joint surface is involved, the sequelae of traumatic arthritis will be left after the fracture heals. Therefore, in the late stage, especially when the weather is cold, it often causes joint pain at the fracture site. Second, in the ankle fracture accompanied by ligament tear, if the ligament tears after the fracture heals, it will become a chronic stale injury. Therefore, when straining, the part of the injured ligament often becomes swollen and painful, which is a manifestation of chronic ligament injury.
