Patellofemoral Pain Syndrome (PFPS)

Front Knee Pain / Runner's Knee

Pain around or behind the patella aggravated by activities that load the patellofemoral joint (stairs, squatting, running, prolonged sitting). The MOST common cause of knee pain in adolescents and young adults (25% of all knee presentations). Multifactorial aetiology: NOT simply "patellar maltracking." Treatment: exercise (quad + hip strengthening) has strongest evidence.
