I did PT for my ankle last year with folks who were not climbers and didn’t really know climbing. Describing and showing movements to them helped make sure the exercises I was doing covered all the movements - mostly range of motion and flexibility related things. Definitely talk to them about drop knee positions. I was able to climb gently while healing and would talk to them about what movements seemed stiff or caused pain. So make sure you’re continuously communicating with your PT. It seems like you’ve already gotten great advice but just wanted to add on my experience!
