Artificial Joint Replacement

　　Generally, due to severe osteoarthritis or rheumatoid arthritis, etc., patients may experience difficulty in movement, and may require artificial joint replacement surgery. It should be noted that not all patients are suitable for this surgery. Whether it is suitable for surgery or not needs to be strictly followed according to the specific situation and medical advice.

　　The common complications of artificial joint replacement surgery can be divided into several aspects. Some complications are related to the patient's disease and physical condition, some are related to the doctor's surgical technique, and some are related to the artificial joint prosthesis itself. Often, the complications and failures that occur in clinical work are the result of the combined effect of multiple factors. Common complications include:

　　1, Loosening of artificial joint prosthesis.

　　2, Mechanical failure of artificial joint, such as dislocation, wear, failure of locking mechanism, and prosthesis fracture, etc.

　　3, Formation of deep vein thrombosis and pulmonary embolism.

　　4, Infection around the prosthesis after artificial joint replacement.

　　5, Postoperative nerve injury, vascular injury, and fracture around the prosthesis.

　　6, Instability and stiffness of the joint after artificial joint replacement.

　　7. Pain after artificial joint replacement.

　　For patients who have undergone artificial joint replacement, they generally do not show other symptoms, and some patients may occasionally experience infection, leading to joint pain. If patients who have undergone artificial joint replacement feel uncomfortable, they must seek medical attention promptly to reduce the occurrence of complications from this surgery.

　　Reasonable prevention is the key to reducing the occurrence of diseases. To reduce the occurrence of joint diseases, it is recommended that everyone pay attention to reducing strenuous exercise in daily life, especially for sports that have a great impact on the joints, and to do it moderately. If joint discomfort occurs, it is important to seek medical attention promptly to reduce the possibility of the恶化 of joint diseases.

　　Artificial joint replacement surgery may only be used for severe joint problems, and whether the patient meets the surgical criteria needs to be comprehensively evaluated by the doctor through various examination methods, such as arthroscopy, X-ray, joint CT, etc., in order to finally determine whether to perform this surgery.

　　There are no special dietary requirements for patients undergoing artificial joint replacement; general normal diet is sufficient. It is important to ensure a rich and balanced diet, and to meet the needs of calories, proteins, and vitamins required for normal human metabolism. Appropriate increase in the intake of vegetables and fruits. In terms of health care, it is important to relax the mind, build confidence, maintain a good attitude, and actively cooperate with the doctor's treatment.

　　For early joint infections, surgery should be performed without hesitation to remove infected blood clots, clear infected tissue, and place irrigation and aspiration tubes for continuous irrigation and aspiration. After such treatment, it is often possible to eliminate superficial infections and save artificial joints. However, infections often involve the surrounding tissues of the prosthesis, and the retention rate of prostheses is less than 20%. If the infection cannot be controlled or delayed infections occur after the above treatment, it is generally necessary to remove the prosthesis and bone cement. After the infection is completely eliminated, joint arthroplasty can be performed after about one year, or osteotomy can be used to improve the patient's gait.
