In the past, people did not know that atoms are made of sub-atomic particles. Some believed the atom was the smallest particle in existence and claimed this as knowledge. This was wrong. However, it was a state of knowledge, like the realization that 1+1=2, entirely different from the supposed "knowledge" that one wakes up on the following day.
If knowledge implies truth then whenever we use that word we are making a bold claim about the nature of the universe that might turn out false in the long run. Things that we once thought we knew get replaced by other things. That doesn't change the fact that, at that point in time, all phenomnological qualities that determine knowledge were met.
