You are right but here we are lucky to have the National Joint Registry. It's really a numbers game. For me it was finding the surgeon with the highest rate of THRs per year local to me. Then a consultation to see if there was a "fit". For both THRs I had a private consultation and then got on the surgeon's NHS list.I guess what I was saying was that sometimes we laypeople don't really know how to choose the 'best' doctor.
