I had both knees done 3 years ago (aged 51) and surgeries were about 2 months apart. recovery was pretty quick, couple of days it was all healed up.
one knee was much better the other, not so much. for people saying physical therapy helped, BS. my physical therapy was stupid.
just stretch on your own, don't be stupid and strain it for a couple of months but keep moving. that's about it.
