Welcome, Evan! I'm a newbie, too, and am coming off my 12th week, I think, from surgery.
By way of suggestions for surgery prep, I'd suggest getting in the best shape you can, without aggravating your condition. I think biking is good, works great after the surgery. Talk to your physical therapy folks - most of the exercises they have are for older, less fit people, so ask for some really good prep exercises. Swimming would be good, too, if you weren't in the frozen tundra of Alaska!
Once done with the surgery, follow instructions about rest, but do the work - all the exercises, the walking, the pain control. I used two trekking poles from Walmart from the day after I got home - they just seemed easier than canes. The walker was useless - used it to walk from my car to the door, 12 steps, when I came home from the hospital. It's been in the basement since I got home.
I've been pretty lucky - my surgery was May 12 2014, and last week, I rode my bike 80 miles, and today, played my first tennis on a soft court for an hour. Follow your restrictions, of course, and listen to what your hip is telling you!
At this early stage, almost all my referred knee pain is gone, and I can sleep in any position I want to. It's only been in the last couple of weeks that the knee stuff has gotten better. My back and the "good" side is a little sore today after tennis, but it's nothing more than a normal workout soreness.
I figure my BHR will last 15 years or more. By then, I won't care much! I'm 62. I have a 10 year old son, and I plan to teach him to drive by going around the little drop-off circle at the nursing home... over and over and over again. I won't know that the scenery isn't changing.
How many BHRs has your surgeon performed? The more the better, everyone says.
Best,
Jim
