the tibial ACL insertion and then overreamed with a can-nulated, straight, fluted 10-mm rigid reamer. After tibial tunnel reaming, femoral tunnels were created using 1 of 3 techniques: 1. Transtibial technique:Withthekneemaintainedat90 of flexion, a 7-mm over-the-top guide (Arthrex) was passed retrograde through the tibial tunnel to position

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).

Methods This cohort study was based on data from a single surgeon’s registry. Patients who underwent primary single-bundle ACL reconstruction with hamstring tendon using the anteromedial 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 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. 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.

The femoral tunnels are located at the center of the distal and proximal halves of the footprint and marked with a radiofrequency probe. 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.

Hence, we introduce this special transtibial anatomical ACL reconstruction technique, in which the most critical step is the creation of a shallow tibial tunnel with a proximal projection to the anatomical location of the femoral tunnel. This technique is indicated for primary ACL reconstructions in skeletally mature patients. Anatomic transtibial double-bundle anterior cruciate ligament reconstruction in a right knee.

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

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. 2017-05-01 · The records of 80 patients (79 men and 1 woman) who underwent ACL reconstruction were evaluated.

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.

2013-11-20 2016-05-01 2017-05-01 2017-08-07 Traditionally, surgeons were trained to use the transtibial technique (TT) for drilling the femoral tunnel. Our study compared the early postoperative period functional and clinical outcomes of patients who had ACL reconstruction with TT and patients who had ACL … 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].

2017-08-07 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 osteoarthritis. 2 Figure 2: Position of bone tunnel center position s chematically drawn 2021-02-02 Dr. Timothy Hosea of University Orthopaedic Associates narrates this procedure.For more information please visitwww.uoanj.com 2020-03-07 2020-06-03 anterior cruciate ligament (ACL) reconstruction with transtibial versus anteromedial portal drilling of the femoraltunnel. Methods: Tenhumancadavericknees(5matchedpairs)withoutligamentinjuryorpre-existing arthritis underwent ACL reconstruction by either a transtibial or anteromedial portal technique. The ACL ToolBox is a comprehensive system that allows surgeons to drill using medial portal, transtibial, or RetroDrill ® techniques. Achieve accurate and reproducible tunnel preparation with this set, which contains marking hooks, drill guides, offset reference guides, dilators, and reamers.
