Sounds like we had some of the same criteria for TKA. Even with all the research and stuff...things will happen. I don't think there is a "textbook" TKA..Everyone has some quirks of some sort...And I had about the best surgery and recovery I know about. I have had absolutely great recovery and now have about 150 ROM.
Remember this is a good place to find support. I have tried to keep my post-op diary up to date. Be sure to start one on the post op diary board. It has been very helpful to have it as a reference. There are lots of readers that don't post and it is helpful to them as well.
I don't think you will need luck because you are ready. Rest well and Post soon.
WORDS TO THE WISE
Anticipate that you will have pain.
Take all meds given when you can (ie..every 4-6 hours as needed...take it every 4 hours)
Don't let the pain get ahead of you
Work as hard as you can in PT (take pain med 30 mins before)
Rest and Ice ICE ICE ICE
Get an elevated toilet seat
Use walker not crutches
My #1 "must have" CRYOTHERAPY UNIT
If you don't get a cryotherapy unit when you have the surgery GET ONE...I prefer Breg because it has a a warranty. It is the best money you can spend. Beg Borrow or Steal one
