Lateral Wedge Insoles With Arch Support in Knee Osteoarthritis

July 23, 2013 updated by: Laval University

Does it Exist a Relationship Between Inclination Angle of Foot Orthoses and Varus Angle of the Knee in the Relief of the Knee Osteoarthritis Symptoms?

The purpose of this is to test lateral foot orthoses with different amount of wedging to find a model that predicts the optimal lateral inclination of foot orthosis based on biomechanical or feelings measures. This study was a cross-sectional study with patients serving as their own control. The investigators recruited 24 knee osteoarthritis. Knee radiography and clinical angles measures was carried out before making orthoses, then motion analysis with an optoelectronic system was performed with each pair of foot orthoses. During motion analysis, five gait trials were carried out in each condition.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Knee pain
Time Frame: At time of device receipt
A 20-cm visual analog scale (0-100) is used to assess pain.
At time of device receipt
Knee adduction moment
Time Frame: At time of device receipt
Measure of the knee adduction moment is a non invasive technic to identify change in medial knee loading, major problem in medial knee osteoarthritis.
At time of device receipt

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Foot orthoses comfort
Time Frame: At time of device receipt
A 20-cm visual analog scale (0-100) is used to assess comfort.
