After surgery, functional training of the joint should be carried out under the supervision of the doctor. For cemented joints, weight bearing is usually allowed for 2-3 days after surgery, and for uncemented joints, a stronger fixation can be obtained only after three months after surgery. Continuous prophylaxis of deep vein thrombosis is required for up to 6-8 weeks after surgery. If an infection is detected elsewhere in the body, it needs to be treated promptly to avoid late infection after artificial joint replacement. After artificial joint replacement, the range of motion of the joint is generally less than that of a normal joint. Deep squatting, sitting on a short bench, short sofa, sitting cross-legged, crossing legs, etc. should be avoided to avoid dislocation of the artificial hip joint. Avoid strenuous exercise such as running and jumping after artificial joint replacement to prevent fracture. After the artificial joint replacement surgery, the patient should be followed up for a long period of time, generally, the patient should be photographed every 3 months in the first year after the surgery, and then every 1-2 years after the surgery. In order to detect possible complications as early as possible, and actively take preventive and protective measures to prolong the life of the artificial joint.
