I'm a 60 yr old hip patient with a 40 yr old brain (my doc's words, not mine), about to enter the world of right side hip arthroplasty. I'm nervous and excited about the prospect of pain free sports enjoyment once again. My doc assures my new hip will last 40-45 years. He claims over 3,000 successful implants in his career, so I'm trusting him. His nurse calls him the "hip guru" I'll keep ya posted in here how things progress and when I ski my first double black diamond run after I'm back on skis after too much time off skis.
