Boy that's tough. I saw my wife go through hip replacement and know how hard that rehab was but it was successful. I can't imagine waiting 4 months to find out you have to do it again. If you haven't done so, run a little recon on you surgeron and see if any negative comes up. You cannot afford not to have the best doctor available.

How are you fixed for reading material, I can send you some antique paperback that are buried somewhere here in the basement.
