dc.description.abstractObjetives: Determine the stability of tibial and femoral components of 20 cementless knee arthroplasties with rotating platform. Methods: The 20 patients (20 knees) underwent an analysis of dynamic radiographs with an image amplifier and maneuvers of varus and valgus which were compared to static frontal and lateral radiographs of the knees and analyzed by two experienced surgeons in a double-blind way. Results: We could observe in this study that both methods showed very similar results for the stability of the tibial and femoral components (p<0.001) using the Kappa method for comparison. Conclusion: The tibial component was more unstable in relation to the femoral component in both static and dynamic studies. Level of Evidence IV, Case Series.
dc.description.abstractObjetivo: Comparar dois métodos de avaliação da estabilidade dosdcomponentes tibial e femoral nas artroplastias de joelho não cimentadas com plataforma rotatória. Métodos: Para isso foram avaliados 20 pacientes (20 joelhos) através de uma análise de radiografias dinâmicas com intensificador de imagem e manobras de estress e em varo e valgo, que foram comparadas com radiografias estáticas em frente e perfil dos joelhos, analisadas por dois cirurgiões experientes, cegos um em relação ao outro. Resultados: Os resultados das análises estáticas e dinâmicas foram comparados e demonstraram forte correlação estatística (p<0,001), utilizando-se o método Kappa de comparação. Conclusão: O componente tibial mostrouse mais instável quando comparado com o componente femoral, tanto na análise estática, quanto na dinâmica. Nível de evidência IV, Série de Casos.
