Rest, ice, compression, elevation.
As a junior installer with 30 yrs in, I also recommend bourbon and ibuprofen.
Get some ProKnees.
I seldom get on my knees anymore, just supervise my help.
That is good to hear, I just lost an old partner of mine that was on his knees til he was 65. Watching him walk hurt.
Try a compression sleeve for your knee, they are cheap feel good.
PS, get your crews ProKnees.
