Highlights & Basics
- Patellofemoral pain syndrome is one of the most common disorders of the knee, accounting for 25% of knee injuries seen in a sports medicine clinic.
- The causes of patellofemoral problems are multifactorial, including abnormal patellofemoral joint mechanics, lower kinetic chain alterations, and overuse.
- Patients typically note the insidious onset of an ill-defined ache localized to the anterior knee behind the patella.
- There is no one physical exam or imaging test that is a standard for diagnosis.
- Treatment is focused on activity modification and correction of specific risk factors.
