I'll add a little about the clunk. I'm 5 weeks post op and I still have a very slight "clunk" in the hip/pelvis when I do a deep knee bend, I'm pretty sure its from the implant. It's just barely there and it bugged me at first, but I'm used to it now. It might go away, I'm not too worried about it.
I think the overall key to this whole thing is that you don't have much of a choice, if your hip joint is shot from OA, you're in pain, you've lost ROM,....I could go on. Resurfacing is the best option for fixing all of that. Sure we're gonna have some issues here and there, but I think most folks will agree that fixing the joint with HR is way better than not doing anything. For a few days after surgery I'd say to myself, "what happens if I don't want this thing in me anymore?" not sure why I would say that, probabaly a standard mental thing when you get a prosthesis, but I'd answer to myself, "what the hell can you do about it?" nothing.
Basically, the joint disease is part of us, the surgery becomes part of us, the implant becomes part of us, recovery,,.. part of us, so and so forth. After awhile, I simply just got used to all of it. This is part of my life and having a BHR in my left hip makes my life way better than it used to be.
