Has anyone had a PAO (Periacetabular Osteotomy)?

Hello,

I had an encephalomyelitis when I was 7 (I am 24 now) and due to that I developed hip dysplasia for which I had surgery at 12 (at least the traumatologist thought that the hip dysplasia was because I have an hemiparsesis and I have an abnormal movement in my right half body). The surgery is called acetabuloplasty.
I have been visiting another doctor for a while (recommended by the last one) and on the last visit, he told me that maybe I can benefit from a modern surgery that "moves my hip" in order to prevent having a total hip replacement. He wants me to do some tests first to see the condition of my hip joint and acetabulum. He didn't mention the name of the surgery, but I have been investigating the surgeon he mentioned, a specialist on this kind of surgery, and the surgery is a PAO.
I will visit the doctor in a month with the tests results, but I am gathering information and experiences about this kind of surgery and the outcomes. Most of the experiences I read are positive but there are others that are catastrophic. I would like to know if any member of this group has had a surgery of this kind and their experience. I have seen that mayo clinic perform this surgery.
