Hi AH,
This extensive forum is loaded with success stories going from recent patients to those who underwent surgeries 15+ years ago. Spend some time reading here and your worries should be lessened. There's no doubt that you're going to have some reservations. Surgery of any kind is always a little daunting. I'm certainly no tough guy, but I almost had zero worries going into this (had bilateral surgeries 10 months ago, and am very satisfied).
I believe my perusing here for several months, hearing about other patients successes and return to much loved activities had an impact on my attitude going into this. Of course, all the stories weren't without issues and problems, but it appeared the majority of those who chose experienced surgeons (like you have) ended up with more than satisfactory results long-term (even those who had initial setbacks). The driving force which provided me a comfortableness in my decision was looking past the surgery and recovery periods (which actually wasn't that bad at all), and envisioning all the great stuff I would be able to do again.
And I'm doing everything I thought I could, and more. I frankly don't even think about my hips anymore.
