Hi Maddox, i'm asking the same question too! I've got an appointment to see the surgeon this wednesday, i'll tell you which one he recommends. Our issue is longevity! I don't care how long it takes to recover from the surgery as long as i am told that it and will last 20 years and maybe more!!! If the doctor garantie me that it will last that long i would do it without hesitation.
But then again garantie or not i need a hip replacement X2. It's the only solution to my problems! I'm sorry I can't be of any help at the moment because i am in the same boat so is everyone on this site. All the best. Sonia s.
