Fourteen porcine knees of Landrace specimens with 2 years old and kg weight were purchased from a commercial slaughterhouse in the state ready for aacl.

Nau T, Spotswood M. Right Rt knee with endoscopic visualization from lateral femoral LF portal. The second aspect to be noted is the direction of bone tunnel axis during graft tension testing. The Journal of Surgical Research.

A standard arthroscopic examination is performed through anteromedial and anterolateral portals. Therefore, to evaluate the Cross-Pin and EndoButton performance for femoral fixation we apply the load directly on the graft. Insert the spinal needle into the knee joint as close as possible to the medial border of the patellar tendon. Morphology of anterior cruciate ligament attachments for anatomic reconstruction: Conclusion The results obtained in this experiment indicate that the Bio Cross-Pin technique promote stiffer fixation during cyclic loading as compared with EndoButton.

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.

This limitation may be encountered in some obese patients, in which case consideration should be given to drilling the ACL femoral tunnel using an outside-in technique or using flexible reamers.


Do adjustable loops lengthen? Care is taken to ensure that the femoral and tibial tunnels are created anatomically in every patient. Both techniques are able to support the immediate post-operative loading applied.

Typically, the spinal needle is located at the height of the interior pole of the patella or slightly higher. AM portal view in hyperflexion.

The free end of the graft was fixed techique the load cell leaving a gage length of 30 mm to mimic the human intra articular ACL length Figure 3. The guide pin is then angled away from the medial femoral condyle and the cannulated endoscopic reamer inserted over the guide pin into the notch.

Closure Finally the knee stability is tested and technnique wounds are closed. In this example, the tip of the microfracture awl is positioned halfway between the centre of the AM and PL bundles white circles.

The first significant slippage of the graft occurs at this point. Passing femoral bone block.

Enrobutton two fixation methods namely Endobutton and Rigidfix are not preferred over one another. This Technical Note describes an arthroscopic technique to prevent migration of the EndoButton using a femoral guide pin incision on the lateral aspect of the femur as an endoscopic portal.

All-inside anterior cruciate ligament graft-link technique: Fact, myth, or common sense: Techniqeu microfracture awl position can be adjusted under arthroscopic and fluoroscopic guidance until the desired position is obtained. In a clinical trial study, a total of 40 patients with rupture of ACL were selected and randomly divided into two groups. E The position of the EndoButton arrow is fixed to the lateral aspect of the femoral cortex.


ACL reconstruction suture button – ENDOBUTTON – Smith & Nephew

ACL reconstruction using the Rigidfix femoral fixation device via the anteromedial portal: Femoral suspension devices for anterior zcl ligament reconstruction: In general, the tip of the tibial passing pin should lie one to sndobutton millimetres anterior to the posterior margin of the anterior horn of the lateral meniscus and slightly medial to the midline of the ACL tibial attachment site Fig.

An ipsilateral semitendinosus and gracilis autograft is used in every case. The Bio Cross-Pin broke in all cases tested. However, arthroscopic ACL reconstruction is more technically complex, and inexperienced surgeons may have difficulty identifying the interposed soft tissue and EndoButton.

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. Endobuttonn concept of complete footprint restoration with guidelines for single- and double-bundle ACL reconstruction. The endoscopic drill bit is inserted into the intercondylar notch through the AAM portal and is seen to lie at the centre of the ACL femoral attachment site.

ACL Technique: Endoscopic Hamstring Graft with Endobutton

Switch the shaver to a Vulcan probe to remove any interposed soft tissue beneath the EndoButton. This more accurate technique not only allows for better visualization but also leads to a decrease in the rate of failure of the ACL reconstruction.

Theoricaly, this point represents the fixation resistance before yielding. The trans-iliotibial band endoscopic portal for direct visualization of ideal button placement.
