As an ortho PA, I would second the notion of tons of communication with your surgeon's team, including the PA. I would also recommend against solutions here in this forum, when you have experts already caring for you who know you in particular and have a formal caring professional relationship established. If you feel you're not getting enough answers, keep calling, and if that doesn't do it, show up in clinic. They will want to help you.
Some times all the discussion about postoperative care that happens while planning the surgery can get mixed up. There's a lot of information that gets thrown at patients all at once, and it would be very unusual for all of it to be retained in memory. Needing to hear the plan again (and again) is normal, as a stressful event can make planning and understanding a few steps ahead very difficult. So, check in regularly.
I always tell patients that their coming by for an extra appointment is not getting in the way of me doing my job; it IS me doing my job.
