If the fracture has entered the recovery period, for example, the bone scab is fully grown and stable, and the fracture is basically fine, it is good to walk more because how long it takes to walk can promote the muscle contraction of the lower limb, thus restoring the function of the lower limb. In addition, it can also stimulate the fracture end and make the fracture grow faster, but it must be decided according to the actual limb condition. If walking more leads to obvious swelling or even pain in the lower limb, it proves that the blood circulation of the limb has not been fully restored, so walking for a period of time to elevate the affected limb and rest, and then continue walking after the swelling subsides, can exercise the blood circulation of the lower limb. But if there is no swelling and pain with more walking, active functional exercise is fine.
