I had arthroscopic surgery in my right hip nearly 7 years ago. Things were extremely bad in there. The surgeon ended up removing all the cartilage and performing a micro fracture. The pain prior to surgery was so intense in my knee and back that I went from being an elite athlete to borderline invalid. The surgery worked, but it took me 4 years to get back to the point where I could compete (triathlon, rowing, running) again. Most people seem to come back faster. I was told I was just buying time until I needed a hip replacement, but so far so good. Wish I had Mobility WOD at the start of this. Good luck with your surgery. Take it slow on the recovery.
