Since, unfortunately, there is not yet a viable way to replace cartilage, those of us with arthritic hips ultimately have but two options--thr or resurfacing. If, like me(and many thousand others), you wish to remain highly active, with no restrictions, there is only one choice, resurfacing. The survival rates of resurfaced hips, performed by the experienced surgeons, actually exceed those of thr's, in the high 90's after ten years. I myself am 13 years out on my first, having had the second one done just recently. The risk you're taking is minimal given the alternative, and if that very small risk is realized, and something does go wrong, you can always be revised to a thr. I agree with Dr. Gross, and others, that all eligible candidates for resurfacing should have it done, in lieu of thr. The entrenched orthopedic community, in my view, has done a terrible disservice to perhaps hundreds of thousands of potential resurfacing candidates, by either not even presenting the option of resurfacing, or actively dissuading persons from undergoing the procedure. I, and many others on this forum and elsewhere, had to do our own research, just as you are doing now, to have discovered hip resurfacing. You are fortunate that you will now have this option.
