This biomechanical study compared suture anchors versus transosseous sutures for repair of quadriceps tendon ruptures using a force of 150 N at a frequency of 0.5 Hz. No significant difference in displacement was found between the 2 techniques with initial loading or with load or no load after 1000 cycles. Displacement after 1000 cycles for suture anchors and bone tunnels was 4.65 and 4.50 mm, respectively. These findings suggest a possible role for suture anchors in repairing quadriceps tendon ruptures. Suture anchors are relatively expensive but require less dissection over the patella and do not involve suture placement about the patella tendon.

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.
