I'm assuming that you're currently running a standard 175mm crank arm length. I don't know what the guys at your LBS told you, but worst case scenario you have to install a new bottom bracket, and that may be included with the crankset you decide to purchase. Good luck finding anything shorter that isn't a single-ring setup.

I once ran a 170mm double on a 7" AM/DH bike. Not for knee issues (which I have), but because I was experiencing excessive pedal strike. I honestly couldn't tell the difference between them and the 175mm cranks on my other trail bike.
