In general, as long as the indications are strictly grasped, adequate preoperative evaluation and preparation are made, good surgical techniques are available, and close postoperative observation and appropriate management are performed, the complication rate is still very low. Complications include intraoperative complications and postoperative complications, and also include local complications and other organ complications. The most important thing to prevent the occurrence of complications is to do the relevant examination carefully before surgery, and to promptly manage and control the existing or potential diseases, including hypertension, coronary heart disease, diabetes, and potential infection lesions. Excellent surgical techniques and comprehensive anesthesia techniques can minimize intraoperative complications. Close postoperative observation and effective preventive measures, including infection prevention, prevention of venous embolism, pain control, close observation of vital signs, and timely detection and treatment of the first signs of complications will lead to a smooth recovery. Once complications occur, timely treatment must be given according to the nature and type of complications, which often requires close cooperation of related departments such as anesthesiology, monitoring room, cardiovascular department, respiratory department, gastroenterology department, etc. to control the complications in the bud in time. Therefore, a strong group of disciplines is a guarantee for maximum safety in artificial joint replacement surgery. Therefore, total hip replacement surgery is not just a matter of putting the joint prosthesis on, but involves scientific handling of all aspects of the entire perioperative period, prevention and management of various complications, various surgical techniques, and also includes the cooperation and collaboration of related disciplines in order to obtain a well-functioning and safe and secure outcome.
