[The Influence of Foot Orthoses on Patellofemoral Pain Syndrome: A Systematic Analysis of the Literature].

The patellofemoral pain syndrome (PFPS) is one of the most commonly encountered disorders involving the knee. The symptoms often lead to a reduction of physical activities resulting in sport- and job-related disabilities and the potential occurrence of severe disorders. Different theories for the development of the syndrome exist which result in different therapy modalities. A change in foot posture and its effect on lower limb kinematics seem to be one potential risk factor for the development of the syndrome. This leads to the assumption that foot orthoses might be a potential therapy device.
