It is incorrect to believe that artificial joint replacement surgery can only be performed once. It is not necessary to delay the artificial joint replacement surgery because of concerns about its longevity. Modern artificial joint replacements are much more advanced than before, both in terms of artificial joint prostheses and surgical techniques. The majority of patients can use the normal use of many years after surgery (85% of patients can use more than 20 years), or even use lifelong. 1, modern artificial joint development so far, whether the prosthesis design, materials, processing technology and long-term clinical results are very good. The clinical long-term follow-up results of many artificial joint prostheses can be used for more than 20 years for the majority of patients. Therefore, some middle-aged and elderly patients (between the ages of 55 and 65) have also been relieved of their pain by artificial joint replacement, and the clinical results have been excellent. The vast majority of patients are able to use it for more than twenty years. As a result, the age limit for surgery is constantly being advanced. The life expectancy is very long. Now we use artificial joint prosthesis, more advanced than the previous generation of prosthesis, more durable. 2. Now our operating rooms are cleaner, which greatly reduces the infection rate of artificial joint replacement surgery, and our infection rate is even lower than that of foreign countries. 3. The surgical instruments used in our surgeries are now very well matched and smooth, which can guarantee a smooth operation. 4.Our current surgical techniques are much better than the previous surgical techniques, which can guarantee a high success rate of surgery. 5.Even if there is a problem with the artificial joint after the artificial joint replacement surgery, according to the current revision prosthesis and surgical techniques, the majority of patients can still resume normal life again. Not to mention that artificial joints continue to develop and progress.
