Skilled knee surgeons?

Hi everyone, I need to find a skilled orthopedic surgeon who specializes in knees. Even better if they are familiar/skilled with revisions. I've had 8 surgeries on my right knee including a partial knee replacement and have actually been turned away from places because they view it as too complicated/too much history. All of my previous surgeries were done elsewhere, I am not familiar with anyone in the Tucson area.
