There are an estimated , ACL repairs in the US each year: most ACL tears occurs from noncontact injuries. The % of the knee ligament injuries. Among femoral cortical suspension devices, the EndoButton CL . to confirm the position of the EndoButton after ACL reconstruction (Fig 3). One device used for femoral fixation of ACL grafts is the EndoButton Continuous Loop (Smith & Nephew. Endoscopy, Andover, Mass). This device has been well.

Three femoral fixation devices for anterior cruciate ligament reconstruction: The laxity is related to loss of fixation by elongation of the graft, graft slippage, and plastic deformation of device.

Services on Demand Journal. The Bio Cross-Pin broke in all cases tested. No fixation devices failed during the cyclic loading test. B Anteroposterior radiograph of a right Rt knee showing reduced position of migrated EndoButtons after arthroscopic reduction.

Displacement at failure mm. All-inside anterior cruciate ligament graft-link technique: The arrowhead indicates the Vulcan probe. Seating of TightRope RT button under direct arthroscopic aacl in anterior cruciate ligament reconstruction to prevent potential complications. Care is taken to ensure that the femoral and tibial tunnels are created anatomically in every patient.

Over the top or endobutton for ACL reconstruction?

A standardized postoperative protocol is implemented for each patient. Journal nedobutton Arthroscopy and Related Surgery. On the Bio Cross-Pin fixation a 9 mm tunnel diameter was drilled for the graft positioning. Switch the shaver to a Vulcan probe to remove any interposed soft tissue beneath the EndoButton. National Center for Biotechnology InformationU. The advantages of this arthroscopic technique include small incisions and direct visualization that can help remove any soft-tissue interposition and reduce a migrated EndoButton.

The diameter of Cross-Pin is higher than Endotape, increasing the volume when the tendon loops. Endoobutton anchor point, however, is different. The method used in our study did not represent the functional loading applied to the graft during flexion-extension movement Zhang et al.

Knee Surg Sports Traumatol Arthrosc. Find articles by Angela Chang. Suture button—based femoral cortical suspension fixation of anterior cruciate ligament ACL grafts can facilitate a fast and secure graft fixation for ACL reconstruction.

Biomechanical analysis of human ligament grafts used in knee-ligament repairs and reconstructions. Our hypothesis was that different mechanical principle to secure the graft inside the bone tunnel results in different performances not being able to support post-operative loading. The Wilcoxon rank sum test was used to compare the linear stiffness variable.

Am J Sports Med. These grafts were then fixed to the femurs by the two fixation techniques: Injury to arteries, such as the lateral superior genicular artery, is possible.

Find articles by Hajime Utsunomiya. The yield point was located away from the failure load. This technique may assist surgeons in understanding how to deal with endobuttin potentially avoid EndoButton migration during anterior cruciate ligament reconstruction.


This factor makes the early postoperative period a critical time for successful surgery Becker et al.

Comparison of fixation on the lateral cortex versus the anterior cortex. A porcine model was used to compare the laxity, the strength, the linear stiffness and the energy associated with each technique.

The procedure was rndobutton accurate for the purposes of this study, in accordance with clinical practice Kousa et al.

Over the top or endobutton for ACL reconstruction?

The yield load has been advocated as the most important variable to be evaluated in the performance of fixation Kousa et al. Footnotes The authors report the following potential conflict of interest or source of funding: EndoButton external cortical support point.

Tendon healing in a bone tunnel differs at endobtuton tunnel entrance versus the tunnel exit: The American Journal of Sports Medicine. Tendon healing in a bone tunnel. The authors report the following potential conflict of interest or source of funding: A biomechanical comparison of anterior cruciate ligament suspensory fixation devices in a porcine cadaver model. Migration of EndoButton after anatomic double-bundle endobuttton cruciate ligament reconstruction.
