Supplementary Data Video 1: Dressings are applied and the patient is returned to the recovery area. The American Journal fechnique Sports Medicine. Use a motorised shaver blade to contour and flatten the wall of the notch. Tendon healing in a bone tunnel differs at the tunnel entrance versus the tunnel exit: Indications and contraindications for the medial portal technique The medial portal technique is versatile and can be used with any ACL graft type and for any primary, revision, single- or double-bundle ACL reconstruction.

ACL Technique: Endoscopic Hamstring Graft with Endobutton

Measure the tibial guide pin position using the method of Amis and Jakob Fig. Attach a padded L-shaped foot rest to the rail clamp along the operative side of the operating table. The force x displacement curves was used to calculate these variables because we are not focusing scl graft strain but the mechanical behavior of the whole system bone-graft-implant. Tendon healing in a bone tunnel.

Similar to any surgical technique, there is a learning curve to the medial portal technique for ACL reconstruction. Tendon-healing in a bone tunnel: Quality assurance in cruciate ligament surgery.

ACL Technique: Endoscopic Hamstring Graft with Endobutton

This is positioned slightly higher than the normal position for standard arthroscopic procedures. Identify the bifurcate ridge as a shelf or prominence perpendicular to the intercondylar ridge in the mid part of the footprint insertion area.

One of the most common orthopedic clinic visits endboutton direct and indirect knee trauma leading to rupture of anterior cruciate ligament ACL. A 6 mm diameter bone tunnel was drilled in inside-out technique to the EndoButton fixation. Mechanical testing Immediately after the graft fixation, each femur was clamped to a custom device with bone cement PMMA and screws.

Hamstring anterior cruciate ligament reconstruction: The mean displacement at ultimate failure load and displacement endobitton yield load for Bio Cross-Pin was significantly lower than EndoButton. This failure mode occurred in 5 cases. Remove soft-tissue interposition and confirm the accurate reduction of the migrated EndoButton. Unlike the transtibial technique where the ACL femoral and tibial bone tunnels are collinear, drilling the ACL femoral tunnel through a medial portal results in divergence of the two tunnels.

The Journal of Surgical Research. Measuring tibial attachment site length. In general, suspension of the EndoButton over soft tissue, such as the ITB, was weaker than that on the femoral cortex.

This minimally invasive approach assists in the correction of the migrated EndoButton to the femoral cortex to the proper position. Anatomy and cryosections in vitro complemented by magnetic resonance arthrography in vivo. Inserting the ruler through the AL portal allows a microfracture awl to be inserted through the AAM portal, giving the surgeon the ability to measure and simultaneously mark the Tecnique femoral attachment site.

The mid- to long-term results of the anterior cruciate ligament reconstruction with hamstring tendons using Transfix technique.

Placement of the accessory anteromedial portal Proper placement of the AAM portal is also critical to the success of the procedure, as it is the most important factor affecting the length of the ACL femoral tunnel.

Our arthroscopic reduction technique allows the surgeon to assess for malpositioning and migration of the EndoButton directly through the LF portal and remove any soft tissue endobtuton between the EndoButton and the lateral cortex of the femur.

Accelerated rehabilitation after anterior cruciate ligament reconstruction. Bone tunnel enlargement after anterior cruciate ligament reconstruction with semitendinosus tendon using Endobutton fixation on the femoral side.

Fourteen porcine knees of Landrace specimens with 2 years old and kg weight were purchased from a commercial slaughterhouse in the state ready for consumption. The medial and lateral tibial tubercles spines with the interconnecting ACL ridge and the medial intercondylar ridge of the tibia are well seen.

Tibial attachment area of the anterior cruciate ligament in the extended knee position. When present, the lateral intercondylar ridge is critical to anatomical ACL femoral tunnel placement since the ACL femoral attachment site always lies below or inferior to this ridge.

The length of the side wall of the notch is measured where the ACL ruler touches the shallow margin of the articular cartilage Fig. Mechanical comparison of biodegradable femoral fixation devices for hamstring tendon graft – A biomechanical study in a porcine model. A 6 mm over-the-top guiding device was used to locate the anatomical ACL insertion.

We believe this arthroscopic reduction technique could be beneficial in the case of a migrated EndoButton during ACL reconstruction of the knee; however, studies on long-term clinical outcomes with a larger cohort will be necessary to determine its efficacy. Preserve some of the remaining native ACL fibres at the tibial and femoral attachment sites to aid with anatomical placement of the ACL bone tunnels.
