ABSTRACT
Abstract Objective To evaluate and compare clinically and functionally patients undergoing primary total knee arthroplasty (TKA) with preservation or replacement of the patella. Methods In a cross-sectional study, the functional results were evaluated and compared, using the Western Ontario and McMaster Universities (WOMAC) and Lequesne scores, of 158 patients undergoing primary TKA (162 knees); in 81 knees the patella was submitted to arthroplasty and in 81 the joint surface of the patella was preserved. Results No significant differences were identified in terms of the Lequesne score (p = 0.585), global WOMAC score (p = 0.169), nor in terms of its subdivisions regarding stiffness (p = 0.796) and functional capacity (p = 0.190). There was a significant difference only in terms of the subdivision that evaluates pain in the WOMAC score, being lower in the group undergoing patellar arthroplasty (p = 0.036). Conclusion In the present study, there was no difference in functional assessment in patients who underwent or not patellar replacement during primary knee arthroplasty surgery. However, individuals in whom the patella was preserved reported more pain.
RESUMO
Resumo Objetivo Avaliar e comparar clínica e funcionalmente pacientes submetidos a artroplastia total primária do joelho (ATJ) com preservação ou substituição da patela. Métodos Em um estudo transversal, foram avaliados e comparados os resultados funcionais, usando escores de Western Ontario and McMaster Universities (WOMAC, na sigla em inglês) e Lequesne, de 158 pacientes submetidos a artroplastia total primária o joelho (162 joelhos), sendo que em 81 joelhos a patela foi submetidaa artroplastiae em 81 a superfície articular da patela foi preservada. Resultados Não foram identificadas diferenças significativas quanto ao escore de Lequesne (p = 0,585), escore global de WOMAC (p = 0,169), nem quanto às subdivisões deste quanto a rigidez (p = 0,796) e a capacidade funcional (p= 0,190). Evidenciou-se diferença significativa apenas quanto à subdivisão que avalia a dor no escore de WOMAC, sendo menor no grupo submetido a artroplastia patelar (p = 0,036). Conclusão No presente estudo, não houve diferença na avaliação funcional em pacientes submetidos a substituição ou não da patela durante a cirurgia de artroplastia primária do joelho. Entretanto, os indivíduos nos quais a patela foi preservada relataram mais dor.
