I hosted Christmas Eve a month from infection surgery and 2 months TKR, the key is to balance activity with rest/ice/elevation. I'd put meat on the stove to brown for lasagna, then elevate for a while, put together the lasagna, then elevate. On another day I'd dust, but rest between rooms, another day I'd vacuum and most importantly, let everyone know I wasn't waiting on them. I put everything out, sat to run my antibiotics through the PICC line and someone brought ME a plate!
Remember 3 months to begin feeling normal and 12 months until you're totally recovered. You can get back to normal life slowly by balancing activity with rest.
