Anatomic anterior cruciate ligament reconstruction using two double-looped hamstring tendon grafts via twin femoral and triple tibial tunnels

Integración tendinosa de plastias autólogas en túneles de diferente calibre. Estudio experimental en ovejas

“…Aparecen aglomeraciones de células en la periferia del injerto sobre la 6ª semana con grandes zonas acelulares en el centro del injerto. Estas regiones hipercelulares son MSC [218] y fibroblastos activados [140] que secretan factores de crecimiento para mantener la remodelación del injerto. El pico de producción de estos factores es entre la 3ª y 6ª semana y cesa completamente a partir de la 12ª semana.…”

Die Zwei-Bündel-Technik – eine anatomische Rekonstruktion des vorderen Kreuzbandes

“…Dies wurde von mehreren Autoren bestä-tigt [5,8,9,22,26]. Seit dem biomechanischen Nachweis, dass die Zwei-Bündel-Rekonstruktion (VierKanal-Technik) sowohl hinsichtlich der anterioren Translation als auch der anterioren Translation in Innenrotation der Ein-Bündel-Technik überlegen ist [31], wird die Zwei-Bündel-Technik zunehmend empfohlen [1,10,20,23,30,32]. Yagi et al konnten zudem in objektiven klinischen Untersuchungen einen Vorteil der Zwei-Bündel-Rekonstruktion (Vier-KanalTechnik) bezüglich der Rotationsstabilität nachweisen [29].…”

“…Other authors have also described the bundles [5,8,9,22,26]. Some biomechanical evidence shows that double-bundle reconstruction with two double-looped grafts is superior to one-bundle technique with regard to both anterior translation and anterior translation in internal rotation [31], thus the two-bundle technique is being increasingly recommended [1,10,20,23,30,32]. In a clinical study, Yagi et al were also able to show improved rotatory stability with the double-bundle technique [29].…”

MRI depiction and 3D visualization of three anterior cruciate ligament bundles

“…The goal of ACL reconstruction is not only to obtain the knee stability without loss of motion, but also to restore the same kinematics as the native knee. Therefore, more anatomical reconstructions in which tendon grafts were placed at original attachment sites of each fiber bundle to mimic the native anatomy as closely as possible, were developed (Odensten and Gillquist, 1985;Muneta et al, 1999;Shino et al, 2005;Zantop et al, 2006;Otsubo et al, 2007;Siebold et al, 2008). Actually, the multiple bundle ACL reconstruction such as double bundle reconstruction has been increasingly popular in the clinical settings (Muneta et al, 1999;Otsubo et al, 2007).…”

“…Actually, the multiple bundle ACL reconstruction such as double bundle reconstruction has been increasingly popular in the clinical settings (Muneta et al, 1999;Otsubo et al, 2007). In 2005, Shino et al (2005 developed the anatomic triple-bundle method to reconstruct the three bundles by dividing the AM bundle in conventional double-bundle reconstruction into medial and lateral bundles. In addition, favorable short-term clinical outcomes of this method were reported (Mae et al, 2013).…”
