Just two cents from me. I've flown with broken feet, toes and ankles, "replaced" knees and one hip. (Victim of a previous, "hard" career.) Unless you legs are really short, don't take a bulkhead row. You need space to stretch your leg and get the weight off the foot ankle. Ideally, get a boarding row seat (if there is mid-cabin boarding). Short of that, I'd rather have a seat in front of me - under which I can at least stretch out my legs - than a hard wall.
