It may be that you dislocated your knee cap. You should have an X-ray of your knee to ensure that there is no associated fracture
of your knee cap or your femur

followed by a period of physiotherapy
. Repeated dislocations occasionally require surgical intervention. The most commonly performed procedure is quickly becoming an MPFL ligament reconstruction.
