Foot Orthoses in Patellofemoral Pain Syndrome: a Prospective Randomized Study of Morpho-specific Versus Placebo Orthoses

Not Applicable
Conditions
Patellofemoral Pain Syndrome
Interventions
Device: Foot orthoses
Registration Number
NCT02250144
Lead Sponsor
University Hospital, Strasbourg, France
Brief Summary

Patellofemoral pain syndrome is one of the most common musculoskeletal disorders. It is defined as an anterior knee pain. Its origin is a conflict during patellar tracking, due to patellofemoral malalignment and soft tissue overload.

A few recent studies seem to show a benefit of prefabricated feet orthoses in patellofemoral pain syndrome, alone or in association with rehabilitation. However, no one has analyzed the outcome of morpho-specific foot orthoses in a prospective randomized study.

The purpose of this prospective randomized study is to compare clinical outcomes in daily living and in sports activities, between morpho-specific and placebo foot orthoses.

Morpho-specific foot orthoses are designed according to the patient's morphotype. They are intended to correct structural defects of the hindfoot, midfoot and forefoot, in the aim to correct abnormal overload during patellofemoral tracking.

GroupInterventionDescription
Morpho-specific foot orthosesFoot orthosesMorpho-specific thermo-molded foot orthoses are designed according to the patient's morphotype. Orthoses are custom-molded from different materials such as BIOFLUX resin, Covercuir MF, EVA300/60, EVA400/70, PE255/55, ABSORB Dur and CAPITON PU.
Placebo foot orthosesFoot orthosesThe placebo foot orthoses will be made with the same principle of molding and with the same materials as for the experimental group. The only difference is that they involve no active corrective insert element : they will be made without morphotype correction.
