Patient: Hi doctor, I am 22 years old, what is the success rate of hip replacement in terms of the surgery? Would having this surgery at an older age have a higher success rate than it does now? Once when I went to the hospital the doctor said the bones were still opening and still opening the body. I would mind having it done later. What is the success rate of joint replacement surgery now? Hospital orthopedic department: Hip replacement is a very mature surgery, surgery technically now there is no problem, the key is that artificial joints have a life span, subject to a variety of factors, if your current symptoms do not affect your activities very much, the surgery should be done later, if not, I suggest you come to the outpatient clinic, I need to do an assessment of you to decide whether to operate. Patient: Doctor, my symptoms are not affecting my activities, but my feet are 5 cm unequal in length. Can I have surgery to make them normal? Why should I do it later? How long do artificial joints usually last? Hospital orthopedic department: The life span of artificial joints is affected by many factors, for young patients to do this surgery should be cautious, especially your symptoms are not very serious, if the problem is simply because of unequal length, I suggest you do not do this surgery, or wait until it affects the function. replacement.
