What is the best way to find a competent physician?

I found a doctor who does Endoscopic Carpal Tunnel Surgery on line. He had favorable ratings. Unfortunately he also was arrested for drunk driving.
I notice that many Plastic Surgeons do the procedure and some Orthopedic Surgeons also do it.
Some call themselves hand Surgeons.
The Hospital For Special Surgery in Manhattan recommends the more invasive surgery over Endoscopic.
I don’t live in Manhattan and I am unsure how to choice the right doctor.
I would appreciate any information you have.
Thank you.
