My TKR was on May 15th, so I'm day 12 or 13. I've had deteriorating knees since my last pregnancy, 30 years ago. There's been nothing unusual (so far) in my recovery process, though I had a terrible time with the oxycontin and had to stop taking it after three days. I've continued with the oxycodone and Tylenol. I still battle swelling quite a bit and of course the pain. My question right now has to do with activity. I do the stretches three times a day and walk when I need to, but what about cardio health? As my knee heals, I'm worried now about the rest of me, particularly cardio health. I'm trying to take a couple of five minute walks a day, but when I do that the knee swells so it's harder to do the stretching for ROM. And when there's swelling, there's pain and so I need to continue the oxycodone every four hours and would like to start cutting back. Thank you!
