Sutlive et al. Identification of individuals with patellofemoral pain whose symptoms improved after a combined program of foot orthosis use and modified activity: a preliminary investigation. Phys Ther. 2004 Jan;84(1):49-61.

“Based on the results of this exploratory study, we suggest that clinicians consider prescribing off-the-shelf foot orthoses combined with a modified physical training regimen as an intervention strategy for patients with long-standing [Patellofemoral Pain Syndrome] who have one or more of the characteristics identified in this study. However, validation of the proposed clinical prediction rule is still needed and should be the goal of a future RCT in which the effectiveness of off-the-shelf foot orthoses is compared with that of customized orthoses (or a placebo) in patients who have been identified using the predictors we found.”Sutlive et al.
