“…The concept of performing and augmenting repairs of specific syndesmotic ligaments has begun to receive increasing attention clinically 24,33 and in biomechanics research. 1,26 As reproduction of the native soft-tissue constraints represents the best option for reproducing original bony kinematics, this approach holds great potential for improving patient outcomes and reducing complications. The purpose of this study was to compare the mechanical behavior of existing methods for syndesmosis fixation with new techniques incorporating various repair augmentations, and to determine which approaches would return the rotational ankle mechanics closer to those of an intact ankle.…”

“…Several authors have previously described techniques using autograft or allograft tendon. 6,12,16,25,31,32,48,53,55 Nonabsorbable suture-tape material has been progressively used for the treatment of ankle instability. The use of the InternalBrace (Arthrex, Naples, FL) for ankle lateral ligament reconstruction has been well described in the literature.…”

Syndesmotic instability is a source of significant pain and disability. Both subtle instability and gross diastasis, whether acute or chronic, require stabilization and may benefit from reconstruction with ligamentous augmentation. The use of nonabsorbable suture-tape has emerged as a promising operative strategy, allowing surgeons to anatomically reconstruct the syndesmosis, in particular the anterior inferior tibiofibular ligament. The current work provides a detailed description of the technique and preliminary results of a patient cohort treated using nonabsorbable suture-tape for syndesmotic augmentation. Level of Evidence: Level V, expert opinion.

Background: This study aims to investigate the malreduction of syndesmosis and its effects on stability. Methods: The biomechanical tests, including the three-dimensional (3D) displacement of the syndesmotic incisura, fibular rotation angle, and torque resistance, were performed on six cadaver legs. These specimens were first tested intact (intact group), then cut all the syndesmotic ligaments and fixed in anatomical position (anatomical model group) and test again. After that, syndesmosis was fixed in 1 cm malreduction (anterior and posterior displacement group) to do the same test. Results: In internal or external load, there were significant differences in torque resistance and fibular rotation angle (internal t = 2.412, P = 0.036; external t = 2.412, P = 0.039) between the intact and post-malreduction groups. In internal rotation load, there were significant differences in sagittal displacement between the intact and postmalreduction groups (P = 0.011), and between the anatomical and post-malreduction groups (P = 0.020). In external rotation load, significant differences existed between the intact and ant-malreduction group (P = 0.034) in sagittal (anterior-posterior) displacement. Significant differences also existed between the intact and post-malreduction groups (P = 0.013), and between the anatomical and post-malreduction groups (P = 0.038) in coronal (medial-lateral) displacement.Conclusions: Malreduction in different conditions does affect the stability of the syndesmotic fixation. The result of the study may reveal the biomechanical mechanism of poor clinical outcome in syndesmosis malreduction patients and pathological displacement patterns of the ankle under syndesmotic malreduction conditions. Level of evidence: III
