FO vs hip replacement

After several months of having to modify in crossfit because of hip pain/lack of mobility I decided to fly up to Boston to see Dr. Millis. The PAO that was done almost 10 years ago has kept my hip socket good. However, my femoral head is not round, is pointed up instead of into the socket and besides arthritis I have developed bone spurs and have loss of cartilage. My choices are to do nothing and let my hip continue to deteriorate until I need a total hip replacement (which would most likely be within a year). The other option is FO - Femoral Osteotomy. Similar to PAO, this surgery cuts the femur, rotates the femoral head and hardware is installed. The recovery is about the same as PAO - about 3 months walking with some kind of assistance. I do not want to keep living with the pain
