| dc.description.abstract | Objective: The objective of the article was to do a comparative study between Smith & Nephew ® prosthesis with constricted polyethylene against the standard in patients submitted to total knee arthroplasty surgery during a short-term follow-up. The aim was to analyze the survival of the related implants due to the range of movement and radiographic aspect. Methods: The sample was divided into two different groups: constricted polyethylene and standard polyethylene. A clinical analysis of the patients was carried out, and it was verified whether implant loosening had occurred. Results: This study evaluated 61 patients in a period of 2 years, 29 in the constricted polyethylene group. The pre-operative deformities were predominantly considered severe. In the postoperative, the tibial-femoral angle varied on average between 5 – 6° of valgus. The total range of movement in the post-operative was above 101° in both groups. One loosened implant in the constricted polyethylene group was observed. Conclusion: The patients treated with constricted polyethylene had the same range of movement as the control group. There was no significant difference between both groups related to loosened implants in short-term follow-up. Level of evidence III; Retrospective study. Objetivo: O objetivo da pesquisa foi realizar um estudo comparativo entre as próteses Smith & Nephew ® com polietileno constrito contra o standard, em pacientes submetidos à artroplastia total do joelho, durante um seguimento de curto prazo. Dessa forma, objetivou-se analisar a sobrevida dos implantes em questão sob o arco de movimento e o aspecto radiográfico. Métodos: A amostra foi dividida em grupos de polietileno constrito e polietileno standard. Foi realizada análise clínica dos pacientes e verificado se ocorreu soltura dos implantes. Resultados: No total, foram avaliados 61 pacientes pelo período de 2 anos, sendo 29 no grupo do polietileno constrito e 32 no polietileno standard. As deformidades pré- -operatórias foram predominantemente consideradas graves. No pós-operatório o ângulo tíbio-femoral oscilou na média entre 5 e 6° de valgo. O arco de movimento total no pós-operatório foi acima de 101° nos dois grupos. Foi observada uma soltura do implante no grupo com polietileno constrito. Conclusão: Os pacientes tratados com o polietileno constrito apresentaram o mesmo arco de movimento do grupo controle. Não há diferença significativa na soltura dos implantes nos dois grupos nesse seguimento de curto prazo. Nível de evidência III; Estudo retrospectivo. | |
