Good luck. I'm probably a few years away yet, but it's definitely letting me know that it's not that far off. Getting tougher for me to put a sock on my right foot, tie my right shoe, etc...
A golf buddy of mine struggled with a bum hip for several years, finally got it replaced four years or so ago. He had it done in the early part of the winter, so when the golf season started that April - he was 100 percent, no issues. So probably a three month recovery.
I don't play with him as much these days, but when I do I ask him how his new hip is doing. "Ah, man... it's great. It's like I'm a new person. Only regret I have is I wish I'd had it done sooner, I needlessly endured a lot of pain and discomfort putting it off as long as I did."
