Abstract:
Objective:It is difficult to achieve proper alignment after total knee arthroplasty (TKA) in patients with extra-articular deformity (EAD) because of altered anatomical axis and distorted landmarks. As of this writing, only case series have been reported with regard to the usefulness of computer-assisted navigation systems for TKA with EAD. This study therefore compared outcomes in TKA with EAD, with and without navigation. Methods:Fourteen osteoarthritis patients with EAD due to previous fracture malunion or operations were assessed. Seven TKAs were performed with navigation (navigation group) and another 7 were performed without navigation (manual group). Clinical and radiographic outcomes were compared before and two years after surgery. Results:The mean postoperative Knee Society function score was significantly higher in the navigation group. No significant difference was found in postoperative range of motion and Knee Society knee score. The rate of outliers in radiographic outcomes tended to be lower in the navigation group. Conclusion:Better clinical outcomes were achieved in cases in which navigation was used. Computer-assisted navigation is useful in TKA for patients with EAD. Level of Evidence III; Case control study. Objetivo:para pacientes com deformidade extra-articular (EAD), é difícil alcançar o alinhamento adequado após a artroplastia total do joelho (TKA) por causa de um eixo anatômico alterado e marcos distorcidos. Somente foram relatadas apenas séries de casos quanto à utilidade do sistema de navegação assistido por computador para TKA com a EAD até agora. Neste estudo, tentamos comparar resultados em TKA com EAD com e sem navegação. Métodos:Quatorze pacientes com osteoartrite com EAD devido a maluniões ou operações de fratura anteriores foram avaliadas. 7 TKAs foram realizados com navegação (navegação em grupo) e outros 7 TKAs foram realizados sem ele (manual de grupo). Antes e dpois anos após a cirurgia, os desfechos clínicos e radiográficos foram comparados. Resultados:O resultado médio da função Knee Society pós-operatório foi significativamente maior na navegação do grupo do que no manual do grupo. Não houve diferença significativa na amplitude de movimento pós-operatória e na pontuação do joelho na joia. A taxa de outliers em resultados radiográficos tende a ser menor na navegação do grupo do que no manual do grupo. Conclusão:foram obtidos melhores resultados clínicos na navegação em grupo. O sistema de navegação assistido por computador é útil em TKA para pacientes com EAD. Nível de Evidência III; Estudo de caso-controle.
