Hi, first I want to praise your ability to be open minded and research all possibilities. It's what got me to consider hip resurfacing instead of the alternative that was pushed to me (THR) in its stead.
I considered and partook of a lot of different possible therapies, from physical therapy to deep tissue massage, to holistic medicines, pain killers, different modes of training my muscles, etc. I even did a workout boot camp thinking to shock my system into correction. I think you'll find many inventive and inquisitive people here, all of whom did their own research into every avenue, since none of us wanted to have the surgery.
Ultimately, though, I came to realize that this was a structural issue at its most basic. Muscle strength, fitness and health probably kept many of us from succumbing earlier, but eventually, muscle can only do so much to overcome the structural defficiency. I lost the cushion between my leg bone and my hip socket, which provided the protection between the bones. Once that went, friction and the inexorable laws of physics take over, and I had to admit to myself that the only way to fix a stripped joint is to replace it with an artificial. The resurfacing replacements for me (two hips) have been great. I won't tell you it's easy, it requires strength (the mental kind) and perseverance, but in a comparatively quick time, you can get your life back.
Just my 2 cents, but I have been where you are, and I wish you good luck in getting to a decision in your own time.
