I had my right hip replaced 5 years ago. I was out of the hospital in a few days, driving in 2 weeks and back to work in 4 weeks.
I live on Long Island and work in NYC, so my commute was not easy the first week back to work. My commute consists of driving to train station, taking LIRR to Penn Station and then walking one avenue to get a subway and do it all over again in reverse after work. I did all of this while using two crutches. Needless to say I was exhausted at the end of the day.
If my doctor told me I have to have my left hip replaced, I'd do it again in a heartbeat.
