RESUMOObjetivo: Avaliar os resultados em longo prazo da osteotomia femoral distal de varização e procurar estabelecer critérios preditivos que possam auxiliar na seleção dos pacientes a serem submetidos a essa técnica. Métodos: Quinze pacientes portadores de osteoartrose do compartimento lateral e deformidade em valgo do joelho foram submetidos à osteotomia femoral distal de varização em "V" e fixação com placa-lâmina lateral, procurando-se alinhar o joelho a 0º no eixo anatômico. O seguimento médio foi de 81,4 meses, variando de 43 a 132 meses. Utilizou-se o protocolo da Knee Society Rating System. Foram consideradas ainda as variáveis: idade do paciente, tempo de seguimento e ângulo anatômico pós-operatórios. Resultados: Foram obtidos 11 resultados excelentes e bons (73%) e quatro regulares e ruins (27%). Conclusão: A osteotomia femoral distal de varização em "V" constitui boa opção para o tratamento de pacientes com osteoartrose do compartimento lateral e valgismo do joelho. Não se confirmaram as variáveis idade do paciente na data de cirurgia, tempo de seguimento e ângulo anatômico pós-operatórios como fatores preditivos dos resultados.

Objective: Assess the long-term results of distal femoral varusing osteotomy and try to establish predictive criteria that could help on selecting patients to be submitted to this technique. Methods: Fifteen patients with lateral compartment osteoarthritis and valgus deformity of the knee were submitted to distal femoral “V” varusing osteotomy fixated with lateral plate, pursuing knee alignment at 0° on the anatomical axis. The mean follow-up period was 81.4 months, ranging from 43 to 132 months. The Knee Society Rating System protocol was employed. Additional assessed variables were the following: patient age, follow-up time, and postoperative anatomical angle. Results: 11 results were regarded as excellent or good (73%) and four as fair or poor (27%). Conclusion: Distal femoral “V” varusing osteotomy constitutes a good treatment alternative for patients with lateral compartment osteoarthritis and valgus knee. The following variables have not been confirmed: patient age at the time of surgery, follow-up time, and postoperative anatomical angle as predictive factors for the results.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
