that's a lot of decision-making to do in a week. I do know that there is a window for success for every surgery and you are wise to be thinking ahead to have the best outcome.
If you haven't already started researching, I would suggest you start here with a search of each of the terms. Keep in mind that this website has a lot of information and people helping people, but the folks with the ordinary, boring complete recoveries don't tend to do as much posting as those with the problems. Remember they wouldn't be doing a procedure unless most people had a successful outcome. Also, try googling the terms and it will pull up a whole bunch of orthopedic websites like AAOS that will explain the procedures. Hopefully, being well informed will let you formulate good questions to ask your OS and make a good decision.
