What causes a knee to slip out of place?

In brief: Patella

Usually this refers to knee cap instability.
This is caused from 1) muscle weakness/imbalance 2) trauma causing ligament/capsule laxity or 3) bone deformity usually from a shallow trochlear groove (the groove in the femur that the patella sits in).
