How long can the artificial femoral head after femoral head replacement be used?

We select patients for femoral head replacement. Generally, we select patients who are older than 65 years old. In addition, if the patient's activity is relatively small, it can prolong the service life of the femoral head. In clinical practice, the service life of the femoral head can be used for more than 20 years. For the elderly, if the acetabular side is relatively normal, artificial femoral head replacement is performed.
