Yes. Dr. Alvin Ong at Rothman. He's known in the area as the guy you go to if you need a joint replaced. I know so, so many people that had hips or knees replaced by him, and they've all had positive experiences. I've never heard a bad word about the man. I'm now 3+ years out from my knee replacement, and aside from it occasionally getting stiff on rainy/cold days, I have zero problems with it.
