no those landings don't hurt. it took me a while to gain the confidence to do them. The only moves I'm wary of doing is most hyper tricks and spinning kicks where I land on my right leg. Since I am twisting and landing at the same time I have to be cautious. But it has a lot to do...
I plan to post lots more videos in the future. Just of me working on tricks or maybe talking and explaining what my years were like when I wasn't tricking. Stay tuned :)

I use a donjoy sports brace. It costs a lot but I had the insurance for it. It's fitted to my knee and provides A LOT of support.
