My older brother had his third one about 15 months ago. (severe motorcycle accident at 18 caused his problems).
He just turned 53. I think he has a titanium hip now and they said this should be a 'life time' one for him.
Follow the Dr's. orders to the letter. He is very healthy and was as active as possible and it still took him months to heal to the stage where they would allow him to start rehab.
He feels like a champ. But in order to get the best (long term)results-his Dr. has advised him to cut back on his physical activity. Hiking, biking, heavy lifting, etc. literally wore the first two out. Low impact is his friend for the next 30+ years.
Oh, and he could not ride motorcycle or even the riding lawnmower for months due to the vibrations...
