Patellofemoral Syndrome: Most Common Demographic and Presentation
Patellofemoral syndrome, also known as runner's knee, is most common among adolescents and young adults, and it is more commonly found in females. This overuse injury is often seen in runners, but it can also affect athletes who perform activities that involve repetitive knee bending, such as jumpers, skiers, cyclists, weight lifters, and soccer players.
Patients with patellofemoral syndrome typically experience a dull, aching pain in the front of the knee and deep to the patella. This pain can be felt during activities like walking, running, going up or down stairs, kneeling or squatting, or after prolonged periods of sitting with the knee bent.
