To be honest, 'knees up' means nothing to me, either. It is a purely British idiom. The Oxford says:

knees-up

• noun Brit. informal a lively party.

Hi Crocodile Babyc,

This expression refers to an occasion when everyone enjoys themselves often in the form of a celebration. As it suggests, knees go up and down because people are dancing in a very animated way.
