Background: Improved biomechanical and clinical outcomes are seen when the femoral tunnels of the anterior cruciate ligament (ACL) are placed in the center of the femoral insertion. The transtibial (TT) technique has been shown to be less capable of this than an anteromedial (AM) portal approach but is more familiar to surgeons and less technically challenging. A hybrid transtibial (HTT
traditional transtibial technique: 1. The ACL femoral tunnel is drilled independently of the tibial tunnel, which results in consistent placement of the femoral tunnel within the native ACL femoral attachment site. 2. The angle of the ACL tibial tunnel does not have to be compromised to accommodate drilling of the ACL femoral tunnel.
Background: Improved biomechanical and clinical outcomes are seen when the femoral tunnels of the anterior cruciate ligament (ACL) are placed in the center of the femoral insertion. The transtibial (TT) technique has been shown to be less capable of this than an anteromedial (AM) portal approach but is more familiar to surgeons and less technically challenging. An ACL graft placed in a 65˚ tibial tunnel with the transtibial technique replicates the low tension- flexion pattern of the native ACL because the boundary of the femoral tunnel is within the green zone (a). Double-bundle anterior cruciate ligament (ACL) reconstruction (DBACLR) is a reasonable transition from single-bundle ACL reconstruction to obtain better clinical outcomes, and most authors believe that it can only be performed through a medial portal. Comparison of Anteromedial and Transtibial ACL Reconstruction Using Expandable Fixation. Ozel O, Yucel B, Orman O, Demircay E, Mutlu S. The influence of anatomical or nonanatomical femoral tunnel position on tunnel widening and clinical outcomes in patients undergoing anterior cruciate ligament (ACL) reconstruction is not fully understood. In the transtibial technique, positioning the ACL tibial tunnel in the posterior half of the ACL tibial attachment site is dictated by the need for the endoscopic drill bit to reach the region of the ACL femoral attachment site and the desire for the ACL graft to avoid impingement against the roof of the intercondylar notch when the knee is in full extension.

Anterior cruciate ligament reconstruction hamstring method is a surgical procedure to replace the torn ACL with part of the The aim of this operation is to achieve anatomic ACL reconstruction using autologous (patient's tendon) under arthroscopic control.
ligament (ACL) reconstruction, it is important to make tibial and femoral entrances in the anatomic location. Techniques such as modified transtibial tech-nique, transanteromedial portal technique, and outside-in technique have been employed for anatomic single-bundle ACL reconstruction.1 Although the transtibial technique is familiar to most
The transtibial (TT) technique has been shown to be less capable of this than an anteromedial (AM) portal approach but is more familiar to surgeons and less technically challenging. 2016-05-01 · Most of the ACL reconstruction is done with isometric single-bundle technique.
The transtibial tunnel technique achieves equal length reconstruction of the anterior cruciate ligament (ACL). This study aimed to investigate whether transtibial tunnel technique can achieve anatomical reconstruction of ACL. For 25 corpses, the anterior soft tissue of the knee joint was detached so that the ligamentous surface was fully exposed, then the knee joint was fixed at 90° with an
The hamstring tendons are harvested to make two 4-stranded grafts. The femoral tunnels are located at the center of the distal and proximal halves of the footprint and marked with a radiofrequency probe. An ACL graft placed in a 65˚ tibial tunnel with the transtibial technique replicates the low tension- flexion pattern of the native ACL because the boundary of the femoral tunnel is within the green zone (a). Transtibial ACL femoral tunnel preparation increases odds of repeat ipsilateral knee surgery.

While results from ACL reconstruction have been highly successful in restoring knee stability and allowing patients to return to sports, a debate continues as to which technique is best for restoring native anatomy and biomechanics. 2013-11-20 · BACKGROUND: Recent efforts to improve the results of anterior cruciate ligament (ACL) reconstruction have focused on placing the femoral tunnel anatomically. Medial portal femoral tunnel techniques facilitate drilling of femoral tunnels that are more anatomic than those made with transtibial techniques. 2013-03-01 · Despite recent criticism of the transtibial technique, it continues to be the most familiar method of ACL reconstruction and with a proven track record of excellent results. Given the comfort level most surgeons have with this approach, we feel simple modifications of this traditional technique may be safer and more reliable for many surgeons than adoption of more unfamiliar methods.

ACL tibial tunnel anatomy during transtibial ACL femoral reaming in the “over-the-top” position with a full femoral reamer versus a half femoral reamer, in comparison to the native tibial ACL footprint. Background Anterior cruciate ligament (ACL) reconstruction using a single-bundle transtibial technique can achieve good or excellent results in more than 90% of patients, but anatomical and Abstract. Background: Transtibial tunneling technique has been the gold standard for arthroscopic ACL reconstruction for many years,. Despite this high level of success, a growing body of literature has questioned whether this technique sufficiently re-creates the anatomy and function of the native ACL.This created a vogue amongst the arthoscopists for anatomical ACL reconstruction using the BACKGROUND Recent efforts to improve the results of anterior cruciate ligament (ACL) reconstruction have focused on placing the femoral tunnel anatomically.
