I don't know if it was anterior or posterior approach. But it is a complete replacement. I am familiar with the 90 degree rule. My mother has a hip replacement. I wouldn't let her sit in my car when I drove her up to see her a couple years ago. Her's had popped out a few times. It was replaced and hasn't happened since . But I didn't want to risk it.
It will be some time before he can ride and drive. We'll probably just take his Mercedes or maybe my wife's NX200 SUV.
Appreciate everyone's responses!
