Biomechanical studies showing no effects of valgus unloader braces on the knee adduction moment

References	Number, brace, methods	Primary outcome measure
Duivenvoorden et al. [7]	80, conventional knee unloader brace, gait analysis, patients with medial OA	No reduction of knee adduction moment, in the brace group at baseline and after 6 weeks
Ebert et al. [8]	20, conventional knee unloader brace, gait analysis, normally aligned knees	Valgus bracing increased knee adduction moments
Gaasbeek et al. [14]	15, conventional knee unloader brace, gait analysis, patients with medial OA	Gait analysis showed that the brace had a tendency of lowering peak varus moment about the knee. This effect was more profound in the presence of higher initial varus deformity angle of the knee
Hewett et al. [16]	18, conventional knee unloader brace, gait analysis, patients with medial OA	Results while wearing a brace showed no significant change in the adduction moment
