Patellofemoral dislocation is when the patella jumps completely out of the walls of the groove in the femur bone, making the joint look horribly deformed.

dislocation of the patella with torn MPFL
The joint usually dislocates to the lateral side, often tearing the medial patellofemoral ligamen (MPFL) on the medial side.


Reduction of patellofemoral dislocation

The dislocation may reduce spontaneously at the time, or it may need to be reduced under sedation or anaesthesia.
