Hello, for advanced femoral head necrosis, of course, it is better to perform joint replacement to solve the problem, conservative treatment can only symptomatically stop the pain, can not improve the function, can not solve the problem at the root, so I strongly recommend hip replacement surgery. The patient is 61 years old, relatively young, and should undergo hip replacement surgery instead of just femoral head replacement surgery. Total hip replacement surgery requires about RMB 55,000-60,000 for imported general joints and about RMB 40,000-50,000 for femoral head replacement. A good hip replacement can last 15-20 years, while a femoral head replacement may last 10-15 years.
