What is Patellofemoral pain syndrome commonly known as?

Patellofemoral pain syndrome is commonly referred to as "runner's knee" because it frequently affects runners and those who engage in activities that involve repetitive knee motion. This condition is characterized by pain around or behind the kneecap (patella) and can arise from overuse, improper alignment, or weak hip and thigh muscles. The term "runner's knee" captures not only the demographic that often experiences this issue but also the mechanics involved in running that can lead to the development of patellofemoral pain. The other options provided refer to different conditions associated with knee or lower leg pain but do not relate specifically to the pain around the kneecap connected with patellofemoral pain syndrome.
