The number of years an artificial hip joint will last is determined by wear and tear and the materials used. Generally ranging from 10 to 40 years. 1. If it is metal to polyethylene friction material interface generally use about 10 to 15 years. 2. If it is a ceramic-to-polyethylene friction interface, it can generally last about 20 to 25 years. 3. In the case of ceramic-to-ceramic friction interfaces, they generally last about 30 to 40 years. 4. If you engage in heavy physical activities after the artificial hip replacement surgery, the wear and tear speed will be accelerated, affecting the use of joint time, if you pay attention to maintenance after the surgery, just walking or engaging in general physical activities, the use of time will be prolonged. Therefore, how many years the artificial hip joint can be used is determined by many factors, such as the degree of wear and tear and the use of materials.
