title: Patellofemoral pain syndrome.
abstract: Patellofemoral pain (PFP) syndrome is a frequently encountered overuse disorder that involves the patellofemoral region and often presents as anterior knee pain. PFP can be difficult to diagnose. Not only do the etiology, diagnosis, and treatment remain challenging, but the terminology used to describe PFP is used inconsistently and can be confusing. Patellofemoral pain syndrome (PFPS) seems to be multifactorial, resulting from a complex interaction among intrinsic anatomic and external training factors. Although clinicians frequently make the diagnosis of PFPS, no consensus exists about its etiology or the factors most responsible for causing pain. This article discusses the pathophysiology, diagnosis, and management of PFP.
