Patellofemoral syndrome or patellofemoral pain syndrome is a term used to describe pain around the patella or kneecap and in the front of the knee.

Also known as runner’s knee or jumper’s knee, it often affects athletes and those who engage in running, basketball, and other sports.

However, patellofemoral syndrome can also affect non-athletes and is frequently seen in adolescents, young people, manual workers, and older adults.

The American Academy of Family Physicians report that patellofemoral syndrome is the most common cause of knee pain in the population. It can be caused by overuse of the knee joint, physical trauma, or misalignment of the kneecap.
