29. Ben Ashworth 2009 Paul Thawley foot strikes the ground in a toe-to-heel pattern to produce an extension moment at the knee In the PFP group, initial contact of the foot with the ground during gait occurred more on the lateral side of the foot, and the center of pressure shifted more slowly from the lateral to the medial side of the foot during foot rollover; this could cause less shock absorption in the foot. Consequently, a greater part of the ground-reaction forces are transferred to the more proximal joints, including the knee. This could result in a higher load on the patellofemoral joint and, consequently, overloading of the patellofemoral joint, which would lead to patellofemoral pain. In addition, the more laterally directed pressure suggests a less pronated position of the foot during the rollover pattern during gait, which could lead to less internal rotation of the tibia. This could place the tibial tuberosity in a more lateral A recent study has shown that subjects with PFP have a delayed onset of gluteus medius relative to control subjects. Strength of the gluteal muscles is also decreased in patellofemoral sufferers where hip abductor and external rotator strength is 26% to 36% lower in females with PFP than age and activity matched controls
