Rehabilitation training after lower third of tibia surgery can be carried out according to early and middle-late rehabilitation stages, which mainly includes joint mobility training and muscle strength training, balance training, etc. 1. Early rehabilitation: eliminate swelling and inflammation through general measures such as elevation of the affected limb, braking, warming therapy, infrared therapy, etc. Perform full-range passive and active joint movements on non-fixed joints to prevent muscle atrophy, venous thrombosis, etc., and promote fracture healing. 2. Intermediate and late rehabilitation: the main goal is to restore joint mobility and muscle strength, to restore the length of the lower leg and to correct the angular and rotational displacement between the fracture ends, so as not to affect the weight-bearing function of the knee and ankle joints and the occurrence of traumatic arthritis in the future. (1) Flexion, extension, internal and external rotation and circular rotation of the ankle joints: increase the range of motion of the joints through active and passive activities. (2) Knee and ankle peripheral muscle training: quadriceps isometric contraction exercises, ankle dorsiflexion, extension, internal and external rotation and circular rotation resistance muscle training, and ankle pump exercises. Step by step, gradually improve the muscle strength. (3) Balance training: with the assistance of double crutches, gradually carry out graded weight-bearing exercises, gradually increase the standing training of the lower limbs, and carry out dynamic and static balance training, including one-legged standing, etc. During the training, pay attention to the knee joint to keep the knee joint in extension. When training, pay attention to the knee joint to keep straight and neutral, prevent rotation, and avoid practicing straight leg raising in the lying position, or practicing active knee extension in the bent knee position, so as to prevent generating shear force, angulation, and torsion stress at the fracture end, which will affect the healing of the fracture. It is recommended that patients go to regular hospitals in time, and carry out standardized treatment and rehabilitation training under the guidance of doctors, so as to avoid delaying the condition.
