Rodrigues PT et al. – The use of medial-wedge insoles was highly effective in reducing pain at rest and on movement and promoted a functional improvement of valgus knee OA. Methods
Aim was to assess the efficacy of medial-wedge insoles in valgus knee OA
30 consecutive women with valgus-deformity knee OA 8 degrees were randomized into 2 groups: medial insole and neutral insole
Both groups also wore ankle supports
A blinded examiner assessed pain on movement, at rest, and at night
Femorotibial, talocalcaneal, and talar tilt angles were evaluated at baseline and after 8 wks of insole use
Results
Significant reductions in the medial insole group were observed for pain on movement, at rest, and at night
In addition, a decrease in Lequesne and WOMAC scores was observed for the medial insole group
In the neutral insole group, a significant reduction was observed only for night pain
An increase in femorotibial angle occurred only in the medial insole group
Moreover, the difference in measured femorotibial angles pre- and postintervention was 1.84 ± 1.42 vs -0.18 ± 0.67 for the medial and neutral insole groups
