Aw gee, Beth! I missed out when you first posted about your doggie and your accident (I'm so sorry for both!) and just want to send warm wishes. What a way to start a new year in a new place. Do you have someone available to help take you to PT after you have your surgery? Until you can get back on your feet? I'm really sorry your knee is messed up but on the bright side there have been major advancements in knee surgery just within the last 5 years. Patients are recovering quicker with less pain. So if you had to mess it up, better now than say 10 years ago.
Any chance you have access to a knee surgical center that your ortho participates with? I've found that they offer the best pre- and post-op care specific to your needs and the nursing staff is pretty johnny on the spot with the pain meds.
