Interesting to learn about the "Superpath" methodology. It sounds like a promising approach for many.
But...there is definitely a place in the surgeon's toolbox for the posterior approach so please do not dismiss it completely. My original THR's were done with a posterior approach because the surgeon needed a complete view of the femur and capsule due to concerns about the very small size of my bones, extensive bone erosion and concerns about exact placement. My revisions were done posterior as well due to extensive tissue erosion and a need to completely debride and clean the area.

I think the key to success in hip replacement is the experienced surgeon, as you recommended.
