“…Possible theories regarding the pathogenesis of rotator cuff disease include decreased tendon vascularity, mechanical impingement on the undersurface of the acromion, or intrinsic degeneration [1][2][3][4] . Recently, some authors have suggested a genetic etiology of tendinopathies including rotator cuff disease 5,6 .…”

Following a failed course of conservative management, arthroscopic rotator cuff repair (ARCR) has become the gold standard treatment for patients presenting with symptomatic rotator cuff (RC) tears. Traditionally, the single-row repair technique was used. Although most patients enjoy good to excellent clinical outcomes, structural healing to bone remains problematic. As a result, orthopaedic surgeons have sought to improve outcomes with various technological and technical advancements. One such possible advancement is the double-row technique. We present a method for repairing an RC tear using double-row suture anchors in a transosseous equivalent suture bridge technique. The doublerow technique is believed to more effectively re-create the anatomic footprint of the tendon, as well as increase tendon to bone surface area, and apposition for healing. However, it requires longer operating times and is costlier. This report highlights this technique for ARCR in an adult by using a double-row transosseous equivalent suture bridge.

“…Whereas intrinsic factors increase tendon susceptibility to injury, extrinsic factors are related to repetitive microtrauma associated with overuse [7,23,24,36,39]. A major factor contributing to this overuse tendinopathy is irritation of the tendon as it passes through a tunnel created by the coracoacromial arch during humeral elevation [5,13,29].…”

Background Recent evidence suggests that the rabbit subscapularis tendon may be anatomically, biomechanically, and histologically suitable to study rotator cuff pathology and repair. However, biomechanical comparisons of rotator cuff repairs in this model have not been evaluated and compared to those in human cadaveric specimens. Questions/purposes We quantified the biomechanical properties of the repaired rabbit subscapularis tendon after (1) single-row, (2) double-row, and (3) transosseousequivalent rotator cuff repair techniques and compared the ratios of repairs to previously published data for human repairs.Methods Tensile testing was performed on 21 New Zealand White rabbit subscapularis tendon-humerus complexes for single-row repair, double-row repair, and transosseous-equivalent repair (n = 7 for each group). Video digitizing software was used to quantify deformation. Load elongation data were then used to quantify structural properties. We compared the ratios of rotator cuff repairs for the rabbit data to data from human supraspinatus repair studies previously performed in our laboratory. For our primary end points (linear stiffness, yield load, ultimate load, and energy absorbed to failure), with the numbers available, our statistical power to detect a clinically important difference (defined as 15%) was 85%. Results The ratios of single-row/double-row repair were 0.72, 0.73, 0.71, and 0.66 for human supraspinatus and 0.77, 0.74, 0.79, and 0.89 for rabbit subscapularis repair for linear stiffness, yield load, ultimate load, and energy absorbed to failure, respectively. The ratios of double-row/transosseousequivalent repair were 1.0, 0.86, 0.70, and 0.41 for human supraspinatus and 1.22, 0.85, 0.76, and 0.60 for rabbit subscapularis for linear stiffness, yield load, ultimate load, and energy absorbed to failure, respectively. There were no differences comparing rabbit to human repair ratios for any parameter (p [ 0.09 for all comparisons). Conclusions Subscapularis repairs in the rabbit at Time 0 result in comparable ratios to human supraspinatus repairs. Clinical Relevance The biomechanical similarities between the different types of rotator cuff repair in the rabbit subscapularis and human supraspinatus at Time 0 provide more evidence that the rabbit subscapularis may be an appropriate model to study rotator cuff repairs.
