Patellofemoral Pain Syndrome

Patellofemoral pain syndrome is a syndrome characterized by pain ranging from severe to mild discomfort seemingly originating from the contact of the posterior surface of the patella with the femur. The causes of PFPS are unclear, but there are several theories. Which tissues give rise to the pain is debated. Equally, there is no agreement as to what is the best method of treating PFPS, and there is not sufficient evidence to support any particular management approach.
