Joe, Every individual's recovery is different depending on your age, general health, cooperation with therapy after surgery, etc. But there should be absolutely no reason you couldn't return to trike riding once you have recovered! In my karate class there is a man in his late 40s who had a hip replacement last year (repairing an old injury from his days of jumping out airplanes in the military), and in six weeks he was right back in karate class and doing better with it than ever!
