Whoa dude, a little young for that! But, my knee is so bad, that's the next step for me on that. The lubrication injections finally lost their effectiveness.
Doubt you'll be down as long as you think though....if u got a good ortho and do your therapy and push it, you'll be able to at least sit in a ground blind in a comfy chair in a couple weeks....won't be climbing no trees!
My neighbor, who has you by 25 years, was out golfing 2 weeks after his first hip replacement.
Good luck with everything.
