Please don't delay it, I followed that route and it backfired big time. When I did try to schedule the op they delayed me so much that by the time I got in I was no longer able to work and struggled to even walk, I was on the max dosage of pain meds (about 30/day). That is one of the reasons my recovery was so slow.
Build up your fitness in the meantime but try to get the ball rolling asap
