Hi Maria,
Welcome!
I had knee surgery in the Summer of 2000. I fell in the basement over some gym equipment. Landed smack on the knee. I thought I broke my leg.
I had to do the PT thing too in the hot weather, not fun. I have A/C and the place does too, but getting there and back was hard. It was my driving leg too.
I ended up with a removable cast for 3 months. I couldn't put any weight on it.
I see your weather forecast on TV. It is hot where you are. Just take it easy and give yourself some time to heal. I had a relapse after mine so don't overdo things. I hope you feel better soon. Take care.
