Nonoperative treatment for patellofemoral pain.

Patellofemoral pain, often called patellofemoral stress syndrome or patellofemoral joint dysfunction, is a commonly seen knee pain syndrome in patients of all ages. It is often a frustrating problem for both the patient and the clinician, as the source of pain can be elusive, making treatment choices difficult. Strategies have been proposed based upon potential sources of pain, including both operative techniques as well as conservative management. Current nonoperative treatment strategies and techniques in the treatment of patellofemoral pain are reviewed. Recommendations and criteria for progression of rehabilitation and suggestions for future research regarding patellofemoral pain are suggested.
