I broke my hip in a bike crash a couple of years ago at 69 and had it pinned (sort of like a post and beam inserted into the bones). I was off the bike from the crash in late August until I took a bike trip in February. I was fine on my bike trip, no pain and no major loss in speed or distance (but I am a recreational rider in the 20-30 mile range). For what its worth, the docs and PTs told me that the surgery for the repair was a bit tougher to rehab than a hip replacement. A friend who is 68 had a hip replaced in November and was back golfing this spring and is doing fine. He was more mobile a bit faster than I was. Bottom line is if you are like me you won't even be aware of it in a few months.
