Just be thankful it’s not your knee is all I can say. I had my hip replaced 2 years ago, wife had her knee 4 months later, I was only 53 at the time (had it done on my 53 birthday actually) and I pray my knees stay healthy after watching her.
I went home, sat for 3 days, said screw this, drove to work and that was it. It’s scary as hell, but sooo worth it in the end.
On a side note, I don’t know how old you are, but my Dr. went a little extra and put one in that the ball and socket are replaceable, like changing a tire. If I wear it out he cut me open, replace them, and never touch the bones, you might want to ask about that.
Same thing happened to me.
After the first one, I woke up with less pain than I had before the operation. The rehab was routine and uneventful.
Then my wife had knee replacement a few years later. I’ve never felt so sorry for her. They eventually had to knock her out and do a manipulation to break up the scar tissue so she could move it correctly. Needless to say she’s not enthusiastic about having another one, even though the other knee is starting to bother her.
Lots of differences between the hip and knee joints.
