Many highly excellent surgeons work in this way.
It’s the modern world, to get the top guy at a price you can afford. He does the surgery in 30 minutes, but his assistants do all the other work.
My knee surgeon told me he did 4 operations per morning on Mondays and Wednesdays. He was really into it, wanted me to watch on the monitor. He went so fast I couldn’t tell what he was doing, but it was obvious that he was very experienced.
I’m debating having knee surgery. I’ve been doing physical therapy, but I stopped a few weeks ago when I got the flu.
I need to go back, and start doing more exercise at home.
Anyway, if my knee isn’t significantly better by summer, then I’ll have knee surgery.
