Risk factors

By Mayo Clinic staff

Runners and other people who routinely do a lot of exercise involving their lower legs may have a greater risk of developing patellofemoral pain. And, women are more likely to develop this condition than are men.

Other risk factors for developing patellofemoral pain include:

  • Weakness of hip muscles, especially the muscles on the outside of the hip (hip abductors)
  • Malalignment of the lower extremity
  • Trauma to the kneecap, such as a dislocation or fracture
  • Wearing worn-out shoes or shoes that don't fit properly
