After the fracture of the lower leg, usually in 6-8 weeks when the fracture reaches clinical healing, you can start to walk down to the ground for functional exercise, but the standard of clinical healing is usually no local pressure pain, and no longitudinal percussion pain. In addition, the most important thing is to review the X-ray, if you see a fracture line blurred, or even a bone scab growth, to achieve the standard of clinical healing, and then try to walk on the ground without pain, you can rest assured to walk on the ground for functional exercise. However, it is important to note that the lower 1/3 of the tibia fracture has less soft tissue around the fracture, so the local blood flow is not as good as other areas, and healing is relatively slow, so special attention must be paid. In addition, there is also a tibial plateau fracture, and if it is a collapsed fracture, bone grafting is necessary during the surgery, and the time to walk on the ground must be longer, which must be about 2.5-3 months.
