Abstract
in English, Portuguese

Objective: To evaluate the efficacy and safety of sliding osteotomy of the lateral epicondyle in correcting rigid valgus deformity in knee arthroplasty.

Methods: A retrospective study of patients undergoing total knee arthroplasty with lateral epicondyle sliding osteotomy between 2006 and 2018. The main outcome was the incidence of complications and adverse events. Secondary outcomes were Visual Analog Scale for Pain, varus stress test, and varus knee thrust during gait.

Results: 19 knees (19 participants) were included in the study. The mean follow-up was 4.2 years. There were no cases of infection or reoperation due to instability. Two participants (10.5%) had mild or moderate knee pain (VAS pain = 4.6 ± 1.9). Two arthroplasties (10.5%) had mild varus stress. No participant presented varus thrust.

Conclusion: Sliding osteotomy of the lateral epicondyle allows fast and safe ligament balance of knee valgus deformities. Level of Evidence I, Case series.

Avaliar a eficácia e a segurança da osteotomia de deslizamento do epicôndilo lateral na correção da deformidade em valgo rígida na artroplastia de joelho. Métodos: Estudo retrospectivo de pacientes submetidos à artroplastia total do joelho com osteotomia de deslizamento do epicôndilo lateral entre 2006 e 2018. O principal desfecho foi a incidência de complicações e eventos adversos. Os desfechos secundários foram escala visual analógica para dor, teste de estresse em varo e flambagem em varo do joelho durante a marcha. Resultados: Foram incluídos no estudo 19 joelhos (19 participantes). O seguimento médio foi de 4,2 anos. Não houve nenhum caso de infecção ou reoperação devido à instabilidade. Dois participantes (10,5%) apresentaram algum tipo de dor leve ou moderada no joelho (EVA = 4,6 ± 1,9). Duas artroplastias (10,5%) apresentaram estresse em varo leve. Nenhum participante apresentou flambagem em varo. Conclusão: A osteotomia de deslizamento do epicôndilo lateral possibilitou o balanço ligamentar das deformidades em valgo do joelho de forma rápida e segura. Nível de Evidência IV, Série de Casos.
