If you are willing to travel, come to Phoenix and see Dr. Jimmy Chow. Dr. Chow is the primary inventor of the Superpath method of minimally invasive hip replacement. He did mine three years ago and I had zero post surgery pain. He replaced my badly misaligned right knee October 1st and lo and behold, again no post surgery pain. He has an international practice. But be aware that he doesn't take Medicare nor insurance.

Where are you? There are other excellent options as well. The Hospital for Special Surgery in NY has some great hip surgeons. Also the Mayo Clinic, Cleveland Clinic, etc.
