My wife had a partial knee replacement last February. She was diligent in her exercises and rehab. First couple of days was rough but it's amazing at how quickly she recovered from it. She's like a new woman now and glad she had it done.
Enough folks have said "rehab" and do your exercises at home - ice packs will help.
I'll just add one more thing . . . good luck with the compression stockings! We had a nurse show us a trick - put a plastic bag over the foot, bunch the stocking down, slide it over the foot in the plastic bag and then roll the foot of the stocking up to remove the plastic bag, then roll foot of stocking back down. I'm a pro now at putting them on. LOL It certainly made it easier though with the plastic bag over the foot trick.
