My advice to anyone getting a TKR is to get on pain management and make arrangements for pain meds for as long as you need them. I am 7 weeks PO and am still on Hydrocodone and I couldn't be doing my PT without it. Please bear in mind that I am not breezing through this surgery like some people. I'm struggling to a 110 ROM. It's awful and I NEED the pain meds. I"m smart enough to wean myself off when the time is right and so you are and most other people who get TKR.
