I'm thinking of trying Pilates. What is it like these days?

I used to do a lot of yoga and Pilates when I exercised. It's been a while since I've done them, so I'm curious how they are these days.

First of all, I have some injuries from the past, so my back hurts and one of my feet hurts, making it difficult to support myself on one leg. I am worried about getting hurt unnecessarily, so I am writing this to ask in advance before my consultation tomorrow.
