At 51 (now 57) I had a complete left hip replacement and my life has never been better. I switched from mountain biking to road biking and love it. I do not have a full range of motion so getting down into the drops is not possible but I sure can do everything else without a problem. I usually bike 17 to 21 miles everyday after work and longer on the weekends, and (thank you goddess!) have had no issues with my hip. My quality of life has totally improved and believe me I'm living it at the fullest!
