Abstract Objective To assess the efficacy of medial‐wedge insoles in valgus knee osteoarthritis (OA). Methods Thirty consecutive women with valgus‐deformity knee OA ≥8 degrees were randomized into 2 groups: medial insole (insoles with 8‐mm medial elevation at the rearfoot [n = 16]) and neutral insole (similar insole without elevation [n = 14]). Both groups also wore ankle supports. A blinded examiner assessed pain on movement, at rest, and at night with a visual analog scale (VAS), the Lequesne index, and Western Ontario and McMaster Universities Osteoarthritis (WOMAC) Index. Femorotibial, talocalcaneal, and talar tilt angles were evaluated at baseline and after 8 weeks of insole use. Results Significant reductions in the medial insole group were observed for pain on movement (mean ± SD VAS pre‐ and postintervention 8.1 ± 1.5 versus 4.2 ± 2.4; P = 0.001), at rest (5.1 ± 2.3 versus 2.7 ± 2.4; P = 0.002), and at night (6.1 ± 2.7 versus 3.1 ± 2.1; P = 0.001). In addition, a decrease in Lequesne (14.7 ± 3.4 versus 9.6 ± 3.8; P = 0.001) and WOMAC scores (74.1 ± 14.2 versus 56.1 ± 14.9; P = 0.001) was observed for the medial insole group. In the neutral insole group, a significant reduction was observed only for night pain (mean ± SD VAS pre‐ and postintervention 5.8 ± 2.4 versus 4.6 ± 2.4; P = 0.019). An increase in femorotibial angle (169.0 ± 3.4 versus 170.8 ± 3.7; P = 0.001) occurred only in the medial insole group. Moreover, the difference in measured femorotibial angles pre‐ and postintervention was 1.84 ± 1.42 versus −0.18 ± 0.67 ( P < 0.001) for the medial and neutral insole groups. Conclusion 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.
