I had mine done a couple of years ago with the Superpath method by the primary inventor of that method -- Jimmy Chow. It is supposed to be an improvement on the Anterior method. I had zero pain after the surgery.

Recently I was chatting with Dr. Chow and mentioned that I had two basic requirements: use the best current method to protect muscles, tendons, etc. and be very experienced in that method. Of the two requirements, I told him i believed that the experience requirement was the most important. Despite the fact that he is an engineer trained inventor of the Superpath method, he completely agreed with me. For example, we both would prefer a surgeon who has done thousands of hip replacements using the posterior methodology (the oldest) vs a surgeon using Superpath who has done it only a handful of times.

Of course, the best answer is to have a surgeon who is using the best current muscle sparing approach and who has done it thousands of times.
