OK Guys, School me on crossbows

[Rottweiler]

After 2 months the doc has finally let my right arm out of the sling. I still have a buncha therapy to go through. I asked him if he thought I'd be able to draw my bow NEXT season knowing this year wasn't going to happen. His reply was "Just sell the bow, You won't be using it anymore. I'll write you an exemption."

Stopped by Bass Pro to look at crossbows on the way home. The "salespeople" weren't much help. Gave me their archery catalog to look over. Not much help there either.

How much is the same between my bow and a crossbow? What am I looking for in a crossbow? How quiet are they compared to my bow?

Right now the only thing I know for sure is I'm going to need one with the winch-looking thing to draw it. Beyond that I'm lost. Advice please
