Abstract

Aim: The aim of this study was to evaluate the effect (6 weeks) of the use of a knee brace and a lateral wedge insole, both in isolation and combined, on the knee adduction moment (KAM), pain levels, kinematics (velocity, stride length, cadence), knee ROM, function, and satisfaction in patients with knee osteoarthritis (OA). Methods: Twenty-one patients with medial compartment knee OA were participated in this study. A relatively light three-point valgus knee brace (VB) and full length custom-made lateral wedge insole with arch support were prepared for each subject. Patients divided into three groups at random. Results: The use of a custom fit valgus brace with lateral edge insole concurrently can reduce a greater peak KAM than use in isolation (30%). In addition, the use of both interventions can improve walking velocity, cadence, and reduce levels of pain in patients with medial compartment OA. Conclusion: All parameters except stride length and KAM in comparison with first day of wearing interventions improved significantly in the combined, concurrent usage group. The use of a lateral wedge insole and a valgus knee brace in combination can improve the kinetic and kinematic parameters in patients with medial compartment knee OA. © 2019 RESNA.
