melk,

I cannot answer your question, but, from those I have talked to that have had the surgery, your best advise from everyone here is this one:
"Mike,

One of the main answers to your question is all about you----Do the required rehab and do it faithfully. If it hurts, too bad, do it. The pain will eventually stop and you should have great movement in your hip. Sit on your duff because 'it hurts' and you will limit yourself. So, do what the doctor and physical therapist say and you should be alright.
