Pearls

  • Abrupt reduction can cause cartilage injury on the patella.
  • Reduce patella by gently extending the knee and simultaneously applying gentle lateral-to-medial directed force to push patella medially.
  • Obtain "sunrise" radiographs to evaluate for fracture.
  • First time dislocations are generally treated conservatively.
  • Physical therapy and range of motion at around 2-weeks improve long term function.
  • Repeat dislocations may require surgical stabilization.
