My trees are 10 years old and the knots on each branch where they have been pruned every year have gotten very large and sprout dozens of new branches each spring. Can I trim below these knots [closer to the ground] to reshape the trees?

You should be able to, but without knowing the exact shape of the tree, we would not be able to tell you how this would affect the future shape of the tree. It would be worth it to have a landscaper who is experienced with crepe myrtles come and look to make sure that the tree will retain a pleasing shape if this sort of pruning is done.
