The rotator cuff repair is a procedure often perform by the orthopedic surgeon. There are multiple techniques and suture configurations for this type of repairs. The double row configuration is one of the most used and consider very effective for mid-size and large size rotator cuff tears. The parachute configuration for this repair is a novel technique that may be useful for mid-size and large size tears, for this repair two medial double row anchors are used and one knotless lateral anchor. Our porpoise was to compare biomechanical performance and footprint coverage of a conventional suture-bridge double-row rotator cuff repair configuration versus a double-row-parachute.  Methods:  This paper shows the biomechanical behavior on a cadaver model of the parachute configuration, and also compares this conformation with a double row in a suture-bridge fashion. Our hipothesis was that the Parachute configuration&#8217;s biomechanical performance is equivalent to the suture-bridging double-row technique.  Results:  The parachute configuration advantages show the advantage of using less anchors, which will decrease the surgical time and also the risks of using multiple hardware in the humeral head.]]></p></abstract>
<abstract abstract-type="short" xml:lang="es"><p><![CDATA[Resumen:  Introducción:  La lesión del manguito rotador es una patología común cuya reparación es un procedimiento realizado por los cirujanos ortopedistas. Existen muchas técnicas de reparación, así como múltiples configuraciones de anclas y suturas para realizar estos procedimientos. La técnica de doble fila es una de las más usadas para rupturas de tamaño mediano y grande con buenos resultados. La configuración en «paracaídas» para la reparación del manguito rotador puede llegar a ser útil para éstas, en este tipo de configuración se utilizan dos anclas mediales y un ancla sin nudos lateral. Nuestro objetivo fue la comparación de la eficiencia biomecánica y cobertura de la huella de una configuración convencional de doble fila «suture bridge» frente a una configuración en «paracaídas».  Métodos:  Este trabajo revisó el comportamiento biomecánico, en piezas cadavéricas, de la configuración de paracaídas y se comparó con la configuración de doble fila tipo «suture-bridge». Nuestra hipótesis era que el rendimiento biomecánico de la configuración de Parachute es equivalente a la técnica de doble fila «suture bridge».  Resultados:  Las posibles ventajas de la configuración de paracaídas son el uso de menos anclas, disminuyendo el tiempo quirúrgico y los riesgos de tener múltiples implantes en la cabeza humeral.]]></p></abstract>
