Methods The success of ACL reconstruction surgery depends mainly on similarities between the graft morphology, tension, position, and orientation compared to the native ACL. Traditionally, a transtibial (TT) technique of the femoral tunnel is the most common method used in single-bundle ACL reconstruction [8, 9, 10]. Recently, many researchers have presumed that the SB transtibial ACL reconstruction places the graft in a non-anatomical femoral insertion site, which largely is considered the most common cause of ACL reconstruction failure. 2–9 To avoid this common complication, the use of the anteromedial portal (AMP) for drilling the femoral tunnel was suggested as a method to place the graft in an 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 The transtibial technique has been shown to produce successful outcomes and was previously the most commonly used option for ACL reconstruction. 5, 6) However, the transtibial technique does not fully place the ACL at its anatomic footprints and tends to place the graft in a more vertical orientation due to anatomic constraints of the tibial 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.
Our study compared the early postoperative period functional and clinical outcomes of patients who had ACL reconstruction with TT and patients who had ACL … 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. However, in our clinical practice, we have found that anatomic DBACLR can be performed easily and exactly through transtibial tunnels just by 2021-02-02 Keywords ACL Anatomy Transtibial Anterior cruciate ligament 3D CT Introduction It has been reported in cadaveric and clinical studies that anatomically placed tunnels better restore normal knee kinematics [24, 25]. In spite of its popularity, the ability of the transtibial technique to reliably position bone tunnels 2016-01-18 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 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.

Medial portal femoral tunnel techniques facilitate drilling of femoral tunnels that are more anatomic than those made with transtibial techniques. The transtibial ACL reconstruction technique has the potential to result in non-anatomically positioned bone tunnels (Figure 3), which might be responsible for abnormal kinematics1 and thus, for early onset of

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.

The angle of the ACL tibial tunnel does not have to be compromised to accommodate drilling of the ACL femoral tunnel. The Pathfinder™ ACL System enables the surgeon to achieve anatomic femoral tunnel positioning in a simple, reproducible way that preserves the technical ease of a traditional transtibial approach.

A medial A number of studies have demonstrated the importance of anatomic graft placement during anterior cruciate ligament (ACL) reconstruction, with biomechanical and clinical outcomes optimized when grafts are placed in the center of both femoral and tibial ACL insertions. 4,5,9,11,19,27,34,36 While a transtibial (TT) technique remains the most common femoral tunnel positioning technique worldwide, numerous publications have demonstrated how tibial tunnel constraint on the femoral drill guide ACL Reconstruction: Antero-Medial and Transtibial Techniques - YouTube.
