Factors that may increase your risk include:

  • Age. Patellofemoral pain syndrome typically affects adolescents and young adults. Knee problems in older populations are more commonly caused by arthritis.
  • Sex. Women are twice as likely as men are to develop patellofemoral pain. This may be because a woman's wider pelvis increases the angle at which the bones in the knee joint meet.
  • Certain sports. Participation in running and jumping sports can put extra stress on your knees, especially if you've recently increased your training level.
