I also work in closed chain in order to achieve good dynamic stability of the lower limb which is often at the root of patellofemoral pain. If the source of the problem appears to be VMO/TFL imbalance with a tight ITB then I would be paying attention to glut med, VMO and tib post in standing. Alternatively the problem may be due to a lack of control of tibial external rotation which can cause maltracking. In this case I would address popliteus recruitment. Since I have been using this approach I have rarely used orthotics and haven't needed to resort to taping.
