ACL Reconstruction With Attachment-Sparing Hamstring Autograft Results in Earlier Graft Maturation and Better Short-Term Clinical Outcome in Comparison to Free Graft: A Randomized Controlled Trial.

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

56 patients with anterior cruciate ligament (ACL) tears were randomized to undergo ACL reconstruction (ACLR) using either an attachment-sparing hamstring autograft or a free hamstring autograft. The primary outcome of interest was graft maturation, assessed using magnetic resonance imaging (MRI) and Figueroa scores. Secondary outcomes included graft swelling, tibial tunnel widening, knee function measured using Lysholm and International Knee Documentation Committee (IKDC) scores, activity levels measured using Tegner scores, and anterior tibial translation (ATT). MRI outcomes were assessed at 3, 6, and 9 months, while clinical outcomes were assessed up to 12 months. Overall, the results revealed that attachment-sparing grafts demonstrated significantly earlier maturation and less graft swelling compared with free hamstring grafts. Attachment-sparing grafts also produced better IKDC scores at 6 and 12 months, although most other clinical outcomes were comparable. These findings suggested that preserving the tibial attachment of hamstring grafts could improve early biological healing and selected short-term functional outcomes following ACLR.
