Patellofemoral Pain Syndrome
A condition characterized by anterior knee pain originating from the patellofemoral joint without specific structural pathology.
Full Definition
Patellofemoral pain syndrome (PFPS) is a common overuse condition affecting the patellofemoral joint, characterized by diffuse anterior knee pain that worsens with activities involving knee flexion under load, such as squatting, stair climbing, or prolonged sitting. Previously known as 'chondromalacia patellae' or 'runner's knee,' PFPS is now understood as a multifactorial condition involving biomechanical dysfunction, muscle imbalances, and altered movement patterns rather than specific cartilage pathology. Treatment focuses on addressing contributing factors through strengthening, movement retraining, and activity modification.
Usage
Usage note: Preferred term over outdated 'chondromalacia patellae' which implies specific cartilage pathology that may not be present.
