i should have had both hips replaced 4 years ago but with runing a small buisness and young family plus a nightmare divorce i havent been able to.being very fit and not knowing if surgeons read this but i am willing to be a guinea pig for a hip op that would allow me to do non contact sports and work manually without worrying to much about wearing the new implants out to quickly.
No need to be a guinea pig, any modern prosthesis should last 25yrs (depending on type and surgeon) with the conditions that you have given, or have I missed the point?
