CONTEXTO E OBJETIVO: O manejo ideal da osteoartrite de joelhos requer combinação entre modalida-des farmacológicas e não farmacológicas. O uso de palmilhas valgizantes no tratamento da osteoartrite medial do joelho é recomendado, mas sua eficácia ainda é controversa. Este estudo objetiva verificar se o uso da palmilha valgizante pode diminuir a dor e melhorar a função dos pacientes com osteoartrite medial dos joelhos. DESENHO E LOCAL: Ensaio clínico prospectivo e randomizado conduzido em hospital de atenção terciária. MÉTODOS: Alocamos prospectivamente 58 pacientes com osteoartrite medial dos joelhos que foram randomizados para fazer uso de palmilha valgizante com amarrilho subtalar (Grupo W) ou palmilha neutra com amarrilho subtalar (Grupo N - controle). Todos os pacientes foram orientados a utilizar a palmilha en-tre cinco e dez horas por dia. Foram aplicados os questionários Western Ontario and McMaster Universities Arthritis Index (WOMAC) e Lequesne, além da escala visual analógica da dor, nos momentos pré e após 2, 8 e 24 semanas. RESULTADOS: Após 8 e 24 semanas, ambos os grupos apresentaram redução dos valores de WOMAC (P = 0,023 e P = 0,012 respectivamente). Não houve diferença estatisticamente significativa entre os grupos nos resultados de WOMAC, Lequesne e escala visual analógica de dor, em nenhum dos momentos avaliados. CONCLUSÃO: O uso de palmilha valgizante com amarrilho subtalar melhorou os sintomas e a função dos pacientes, mas não foi melhor que placebo. REGISTRO DE ENSAIO CLÍNICO: NCT01739296.
