It's been almost a year and it is doing well. I got off of the pain meds around the three week mark (one of the conditions for driving to work). There were periods of discomfort while sitting at my desk. Getting up and moving around really helped.
On the trip we stopped every couple of hours so I could walk a bit. But to be truthful, two hours is about all I've ever been able to do without needing to stretch my legs.
One note: My doctor did not recommend flying at that juncture. There is an enhanced threat of blood clots after the surgery that dissipates over time. I was fortunate and my place of business accommodated my needs.
I will state again that it was probably three months before I was able to sleep through the night. It would just kind of throb after a while, get up walk around and go for the next round of sleep. Benadryl helped a lot but tends to make me "fuzzy" when I first awaken.
I had to endure 6 weeks of physical therapy when my knee first became painful (sudden). I attribute my speedy recovery to the physical therapists advice that if I did end up needing a knee replacement that doing the exercises BEFORE the surgery would make it easier to recover post surgery.
All that being said, I am most definitely not looking forward to having my other knee replaced!
