I had knee surgery about 5 months ago and now a new MRI shows that I have a menicus root displacement. How can that be? It wasn't there during surger?

In brief: Retear
We are at a disadvantage because we were not there at the surgery, but it is not uncommon to retear a meniscus or extend a preexisting tear. The fact that you had surgery presumably for a tear speaks of the underlying weakness of the meniscus.
So a new displaced meniscus root tear most likely represents a new tear after the surgery.

In brief: Not too unusal
Several things happen with surgery.
Some areas are harder to see with arthroscopy than others, and without any indications of additional injury, that area may have been overlooked. Your meniscal root displacement may have been present in the prior study, or may not. You can ask your Doctor to have the two studies compared. Remember that changes in stress after surgery can cause additional injury.
