Hi Alan,
As far as I know there have been no individuals who are members of the site who have pursued the PRP approach. If you decide to do it, you will be the first and we will appreciate your input. I have heard that the most rugged solution for the hip is ceramic on ceramic. The only side effect I have heard is the occasional squeak. This site is specifically for people to report their progress through the years. As the site matures, you’ll get the real low-down on the effect that running has had on the hip. 5 years in, mine is still doing fine. Will keep you posted though.
