Kevin's dad had both hips replaced; one in the 90s and the 2nd one last year. If your dad does the Physical Therapy, he'll recover a lot quicker. Kevin's dad didnt want it, so he was bed bound for awhile and had everyone waiting on him hand and food. He was in pain for awhile too. But the man was stubborn as hell and didnt do anything the Dr.s said to do. As long as your dad plays it easy and doesnt rush his covery, takes the pain meds and does teh PT, he should heal up pretty speedy and easily.
