1. Pay attention to the isometric contraction of the gluteus, quadriceps and gastrocnemius muscles, the passive activities of the knee and ankle joints, and the activities of the metatarsophalangeal and interphalangeal joints of the foot as soon as possible after the pain is slightly reduced in the early post-injury period, so as to prepare for walking in the future. 2. Pay attention to increasing the stability of the fracture end and the broken bone block to avoid poor rectification due to poor rehabilitation action, angular deformity resulting in non-parallel knee and ankle joint surfaces, improper weight-bearing line of the limb, and an increase in bone discontinuity. 3.Full weight-bearing functional exercise as early as possible after surgery, and avoid bending stress and rotational stress during exercise. 4, in the case of continuous traction of the heel bone, in addition to pay attention to avoid excessive traction will cause delayed healing, with appropriate hands to support the hip lift method for muscle isometric contraction exercises, that is, practice with both hands to support the hip and will be able-bodied limb stirrups up, the patient hard tense the injured leg muscles, empty stirrups heel, and then relax, a stirrups a loose, repeated exercises, generally more than 300 times a day in the cast, until the cast until the cast is removed. However, it should be noted that the injured limb should not be stretched by force alone, so as not to make the fracture forward at an angle by the influence of traction. 5. Patients with splint fixation can practice knee flexion and extension and ankle internal and external swing activities at an early stage (after 2 weeks). The method is to make the ankle joint dorsiflexion (extension), plantar flexion and extension and flexion of the toes, more than 300 times a day, while doing ankle joint massage and moving the ankle and toe joints until the cast is removed.
