Artificial joints are like a car, a machine, cherished, loved and maintained. It will last longer, otherwise it will be damaged in a short time. The artificial knee joint has the possibility of wear and loosening after long-term use. This affects the life of the artificial joint. The life of the artificial joint is a matter of concern for every patient, who wants his or her artificial joint to last longer. What should I do to maintain my artificial joint after replacement? Infection, obesity, osteoporosis and overuse are all causes of artificial joint failure. Maintenance measures include reducing wear and tear, preventing osteoporosis, avoiding injury, avoiding infection, and regular follow-up visits. First, reduce wear and tear: is the most important. Specifically, weight reduction, patients who have received artificial joint replacement must maintain and control their weight. Since most of the force on the hip joint comes from our weight, reducing weight will reduce wear and tear on the artificial joint. Patients after joint replacement should reduce their activities appropriately. Long distance walking or inappropriate weight bearing will undoubtedly increase the wear and tear of the artificial joint prosthesis and should be avoided as much as possible. Long time walking or standing, climbing hills and stairs should be avoided. Swimming, bicycling and other activities are not only good for health, is relatively little wear and tear on the joint prosthesis of sports activities, it is not recommended to engage in heavy physical labor, and strenuous sports. However, general sports and work can be carried out. Second, prevention and control of osteoporosis Patients should prevent and control osteoporosis, osteoporosis is not conducive to the fixation of the artificial joint, a long time may occur the artificial joint loosening and subsidence. Therefore, patients should actively prevent and control osteoporosis from diet, medicine, sunshine and proper exercise. Some calcium supplements can be taken to regulate it. Timely detection and timely treatment. Avoid injury Under the guidance of the doctor, “train muscles to protect joints”, sitting on a low stool or squatting may cause the artificial joints to hit, which may lead to loosening or even dislocation of the artificial joints. Patients need to strengthen their muscles. Good muscle strength not only allows the patient to move freely and enhance the coordination and sensitivity of the limbs, but also reduces the forces on the joint to a certain extent. If a traumatic fracture occurs around the artificial joint, the fracture will not heal easily and will easily lead to loosening of the artificial joint, so more attention should be paid to avoid trauma and falls. Fourth, prevention and control of infection late artificial joints may still occur joint infection, which is due to the possibility of transferring bacteria from other parts of the body to the artificial joint parts, causing joint infection. Therefore, it is important to effectively prevent infections in all parts of the body and to provide timely treatment when infections occur in other parts of the body (such as colds, pneumonia, boils, etc.). Fifth, pay attention to follow-up visits The surgeon is like a car “4S” store, need to go to “maintenance” regularly. Be sure to pay attention to the lifelong follow-up system, in accordance with the requirements of the doctor to do their own surgery for review, check the function of the prosthesis, check the bone density for osteoporosis, to understand the patient’s functional exercise and recovery, so that early detection of artificial joint loosening and other adverse tendencies. If there is any discomfort, you should communicate with your own doctor in time to remove hidden problems. Regular follow-up visits are good for early detection of problems and timely treatment. It helps to prolong the life of the joint. Early post-surgery review should be done diligently so that the doctor can guide the patient’s rehabilitation exercises.
