Query: Awesome for my knee surgery and same one used by PT

I got this ColPac to prepare for my knee surgery. It was the same one they used at my PT when we were trying to avoid surgery. I got the big on (12.5 x 18.5)so i could wrap it around my knee and get the under side of my knee also. Actually came to purchase another for my Mom who will have same surgery in a few days.
