It's been over 1 year since rod removal. Most folks who did the surgery around the same time as me also have gotten their rods removed. Life is fully back to usual. I snowboarded this season for the first time since the surgery, and it was great. I am no athlete, so not really sure how much it impacts my sports, but I was able to pick up most of my snowboarding skills after about 3 green runs and 1 blue run, since my center of weight has changed post-surgery. I do think I walk faster than before now that my strides are slightly bigger. Nobody could tell I did this surgery, so they are usually surprised when I tell them.
I still recommend that you save up enough money before doing the surgery, like at least the amount of (the surgery + room and board + care giver cost for 2 weeks) * 1.5. You don't want to be stressed during the recovery time, which will really hurt your mental state and then potentially physical state. And there's not really "too late to do it". I've seen/heard of people in 30s, 40s, and even 50s go through it. You really want to make sure that the other aspects of your life, friends, family, career, financial states, etc, are in a good and healthy place before doing this procedure.
