Hi: Some rhetorical questions for both you and your physician.
Why are you wearing a brace at all? I wore a brace until the femoral block wore off, then never again.
Why is your incision bandaged so heavily? Except for immediate post-op, mine was never bandaged.
Elevation results are best achieved by putting your leg on a big pillow so that your knee is higher than your heart.
For icing, I used frozen peas in 3 separate baggies - one for each side, one on top - with a cloth towel between skin and ice.
In your recovery, try to stay calm, take your medication and if your are still in pain, ask for more. The control of pain is essential to recovery because this is a painful operation.
Also, your recovery is your recovery meaning that it is unique to you. Don't worry about where you think you should be, but where you are! Do a little bit at a time, rest, relax and let yourself heal.
Take your meds on time, rest a lot, elevate and use ice to help reduce swelling. Soon enough, you'll be feeling much better and so glad you made the decision to fix your knee with a new one.
Good luck!
