Just like climbing roses, pruning rules for Knock Outs are similar, but with a few exceptions.

Knock Outs tend to grow in phases bloom - rest - bloom. If a mid-season trim is in order, it is best done following a blooming period while in the resting phase. Deadheading will also help to stimulate new bloom clusters and overall growth.
Knock Outs tend to produce a lot of rose hips that inhibit flowering triggering dormancy , so trimming these off will keep your Knock Out blooming.
