The oak is shooting these deformed acorns. What is the cause and what can be done? Thanks

Do they look like the acorns on this page?

You might have knopper galls, a symptom of a certain kind of wasp. There are actually wasp larvae growing inside the acorns. It may look really weird, but the presence of the galls won't harm the tree.
