AB  - Dislocation  of  the  patella  generally  results  from  a  traumatic  event.1–9  It  is  most  commonly  due  to  a  direct  blow  to  the  flexed  knee.  It  may  also  occur  from  a  forceful  quadriceps  contraction  while  the  femur  is  internally  rotated  on  the  tibia.  Many  patients  may  not  notice  the  dislocation  as  it  may  spontaneously  reduce  immediately  after  the  injury.  There  are  numerous  theories  as  to  the  predisposition,  if  any,  to  a  patella  dislocation.1,2  These  include  adolescents,  females,  flat  intercondylar  groove,  joint  laxity,  “knock-knees”  or  genu  valgus,  large  Q-angles,  obesity,  and  vastus  medialis  muscle  atrophy.  This  condition  is  most  commonly  seen  in  adolescents  and  females.
