My senior year in college I had to have one removed. I don't remember recovery being all that long. Although I was supposed to still be in the boot for graduation and refused to wear it. I was in a bit of pain that afternoon.
My surgeon swam at the pool where I was a lifeguard. That was cool because she okayed me getting back in the water pretty quickly. As long as I didn't push off with that foot.
Mine was caused by a biomechanical issue. My ankles tend to lean in and my foot stays flexible when I push off as I walk. I don't use anything special, but have focused on the ankle thing to keep the one on the other foot from becoming an issue.
It's been 15 years since my surgery.
