Background: Shortcomings to tibial-side fixation have been reported as causes of failure after anterior cruciate ligament reconstruction. Adjustable-loop suspensory devices have become popular; however, no comparison with hybrid fixation (ie, interference screw and cortical button) exists to our knowledge. Purpose: The purpose of this study was to compare the biomechanical properties of adjustable loop devices (ALDs) in full-tunnel and closed-socket configurations in relation to hybrid fixation. We hypothesized that primary stability of fixation by a tibial ALD will not be inferior to hybrid fixation. Study Design: Controlled laboratory study. Methods: Tibial fixation of a quadrupled tendon graft was biomechanically investigated in a porcine tibia–bovine tendon model using 5 techniques (n = 6 specimens each). The tested constructs included hybrid fixation with a cortical fixation button and interference screw (group 1), single cortical fixation with the full-tunnel technique using an open-suture strand button (group 2) or an ALD (group 3), or closed-socket fixation using 2 different types of ALDs (groups 4 and 5). Each specimen was evaluated using a materials testing machine (1000 cycles from 50-250 N and pull to failure). Force at failure, cyclic displacement, stiffness, and ability to pretension the graft during insertion were compared among the groups. Results: No differences in ultimate load to failure were found between the ALD constructs (groups 3, 4, and 5) and hybrid fixation (group 1). Cyclic displacement was significantly higher in group 2 vs all other groups ( P < .001); however, no difference was observed in groups 3, 4, and 5 as compared with group 1. The remaining tension on the construct after fixation was significantly higher in groups 3 and 4 vs groups 1, 2, and 5 ( P < .02 for all comparisons), irrespective of whether a full-tunnel or closed-socket approach was used. Conclusion: Tibial anterior cruciate ligament graft fixation with knotless ALDs achieved comparable results with hybrid fixation in the full-tunnel and closed-socket techniques. The retention of graft tension appears to be biomechanically more relevant than tunnel type. Clinical Relevance: The study findings emphasize the importance of the tension at which fixation is performed.

Achilles tendon reconstruction is an effective method of repairing Achilles tendon rupture defects. We introduce a new approach for Achilles tendon reconstruction using transversal calcaneal anchored autogenous semitendinosus tendon graft. The study aimed to evaluate the clinical role of this new Achilles tendon reconstruction. We retrospectively enrolled patients who underwent Achilles tendon reconstruction using transversal calcaneal anchored autogenous semitendinosus tendon graft for acute Achilles tendon rupture defects from 2016 to 2021. The clinical and radiological results were assessed at the preoperative and the final postoperative follow-up with Visual Analog Score (VAS) scores, American Orthopaedic Foot & Ankle Society (AOFAS) scores and Achilles tendon Total Rupture Scores (ATRS). Besides, at the last postoperative follow-up, the difference in ankle range of motion between the two side of the patients and the incidence of postoperative complications were recorded. Results revealed patients had significantly lower VAS and higher AOFAS and ATRS ( P < 0.01). Compared to the healthy ankle, the operative ankle showed significant deficits in ankle range of motion ( P < 0.01). Additionally, radiological results showed no noticeable signs of tunnel enlargement in the calcaneus and no patient had re-rupture. Transversal calcaneal anchored Achilles tendon reconstruction with free semitendinosus tendon autograft is an effective treatment option for patients with acute Achilles tendon rupture with large defects and have high postoperative exercise demands.
