Is Patella Resurfacing Associated With Postoperative Extensor Mechanism Disruption After Total Knee Arthroplasty? A Systematic Review and Meta-Analysis.

Este estudio ha sido identificado como potencialmente de alto impacto. La métrica de alto impacto de OE, basada en la inteligencia artificial, estima la influencia que puede tener un artículo integrando señales procedentes tanto de la revista en la que se publica como del contenido científico del propio artículo. Desarrollado mediante el procesamiento del lenguaje natural más avanzado, el modelo de Alto Impacto de OE predice con mayor precisión el futuro rendimiento de las citas de un estudio que el factor de impacto de la revista por sí solo. Esto permite reconocer antes las investigaciones clínicamente significativas y ayuda a los lectores a centrarse en los artículos con más probabilidades de configurar la práctica futura.

Resumen del estudio

Nine randomized controlled trials comprising of1569 patients undergoing primary total knee arthroplasty (TKA) had two groups; one whom 773 (49%) patients underwent patella resurfacing and another group with 796 (51%) patients who did not. All included studies had a minimum follow-up of two years (mean 6.4 ± 2.5 years). The outcomes were the incidence of extensor mechanism disruption–related complications (patellar fracture, quadriceps tendon tear, patellar tendon tear) and the need for surgical intervention for extensor mechanism disruption. Overall, the results demonstrated that extensor mechanism disruption after TKA was rare (overall incidence 0.4%), and patella resurfacing was not associated with an increased risk of extensor mechanism disruption or surgery for extensor mechanism disruption compared with nonresurfacing. These findings suggest that concerns about extensor mechanism failure should not be a primary determinant when deciding whether to resurface the patella during TKA.
