Purpose: To evaluate the biomechanical properties of 3 scapholunate repair techniques.
Methods: In 51 cadavers, the scapholunate ligament was exposed through a dorsal approach, incised at its scaphoid insertion, and repaired using 1 of 3 techniques: 2 single-loaded suture anchors, 2 double-loaded suture anchors, or 2 transosseous sutures. Twenty-four repaired specimens underwent load to failure (LTF) testing using tensile distraction on a servo-hydraulic machine. Twenty-seven specimens underwent cyclical testing to measure gap formation at the scapholunate joint.
Results: The mode of failure was suture pullout through the substance of the ligament in 22 specimens, failure at the bone suture interface in 1, and anchor pullout in 1. Double-loaded anchor repairs demonstrated a significantly higher mean ultimate LTF compared with single-loaded anchor (91 N vs 35 N) and transosseous (91 N vs 60 N) repairs. Transosseous repairs demonstrated a higher mean ultimate LTF compared with single-loaded suture repairs (60 N vs 35 N). After 300 cycles, the average gap for the transosseous repair group was double that for the single- and double-loaded repairs, although not statistically significant.
Conclusions: Primary scapholunate ligament repairs using double-loaded suture anchors demonstrated significantly higher strength compared with single-loaded anchors and transosseous repairs. On cyclic loading, transosseous repairs demonstrated the greatest gap formation with no measurable difference between single- and double-loaded repairs.
Clinical Relevance: In a cadaveric model for primary repairs, double-loaded suture anchors demonstrated the highest LTF and offer a similar but unproven performance in vivo.

The clinicopathologic conditions of the long head of the biceps tendon vary, encompassing tendinitis, peritendinous inflammation, hypertrophy, and partial or complete tears. These symptoms are typically linked with SLAP tears and instability of the long head of the biceps tendon, often resulting in partial displacement or complete dislocation. The choice between tenotomy and tenodesis depends on varied factors.

Acute, traumatic distal biceps tendon ruptures are a common injury in the middle-aged athletic male population, with direct anatomic surgical repair being the most effective technique to restore maximal strength. Multiple techniques for distal biceps tendon repair have been described, including single- or dual-incision approaches and tendon fixation with cortical buttons, interference screws, suture anchors, and transosseous sutures. In this Technical Note, we demonstrate an anatomic distal biceps tendon repair technique with a single-incision approach using 2 all-suture cortical buttons.

Remplissage is a procedure that decreases the rate of recurrent instability after arthroscopic stabilization in patients with an engaging Hill-Sachs lesion. This technique involves capsulotenodesis of the infraspinatus tendon and posterior capsule into the Hill-Sachs lesion using 2 knotless anchors with suture passage through the infraspinatus tendon guided by a percutaneous needle. Previously described techniques use knots or anchor placement through the infraspinatus, which can be challenging to control and irreversible if tendon penetration occurs in an undesirable location.

Background: The Latarjet and other bony augmentation procedures are commonly used to treat anterior shoulder instability in the setting of significant glenoid bone loss. Although several fixation strategies have been reported, the biomechanical strength of these techniques remains poorly understood.
Purpose: To perform a systematic review of the biomechanical strength of glenoid bony augmentation procedures for anterior shoulder instability.
