The quality of the ceramic joint is relatively the best in the hip replacement process, with a small coefficient of friction and excellent pressure matching of the entire bone and all joint surfaces, but the specific service life is not entirely determined by the quality of the joint prosthesis itself. Although statistically 15-20 years should be fine, there is a relationship with daily use and the weight of the person. No matter how good the quality of the joint is, even if it is a 4th generation ceramic hip joint, if there is a large amount of exercise or heavy lifting every day after the surgery, or even if the person’s weight causes a large load on the hip joint, it is possible that the joint prosthesis will wear very badly in 5-10 years and will need to be replaced. On the other hand, the usual maintenance is very good, the weight is not large, simply to meet the daily life may use more than 20 years, so the decisive factor is to see how to use itself after the surgery, not how good the quality of the joint prosthesis used.
