Comparable Biomechanical Results for a Modified Single-Row Rotator Cuff Reconstruction Using Triple-Loaded Suture Anchors Versus a Suture-Bridging Double-Row Repair

The Influence of Rotator Cuff Tear Size and Repair Technique on Creation and Management of Dog Ear Deformities in a Transosseous Equivalent Rotator Cuff Repair Model

“…Alternatively, Kim et al 11 reported on a technique of using the suture tails from the lateral row anchors to create an additional site of compression in the marginal dog ear deformity, the so-called modified suture bridge. Other authors have purported using additional anchors 11 or a triple-mattress repair with a single row of triple-loaded suture anchors 12,13 to manage these deformities. However, there is no literature to quantify the size of these dog ear deformities before and after these various repair techniques.…”

“…4 Despite the inherent advantages of this technique, the transosseous-equivalent rotator cuff repair also possesses some frequently encountered shortcomings, notably redundancies in the rotator cuff tissue, which are commonly referred to as ''dog ear'' deformities. Various suture patterns [10][11][12][13] have been created to minimize the occurrence of these deformities or manage them once they are formed, as consequences may include inadequate footprint restoration and impaired healing of the cuff to the greater tuberosity. Commonly encountered in other surgical wounds as well, dog ear deformities are the result of an asymmetric puckering or accumulation of tissue, typically in the center or at the apices of an incision.…”

Advances in biology and mechanics of rotator cuff repair

“…However, the biomechanical properties did not show a significant improvement compared to single-row repairs using modified suture configurations [72][73][74][75][76]. Furthermore, the potential benefit of improved footprint coverage could not be transferred in the clinical setting as the clinical results of double-row repairs are still comparable to single-row repairs concerning clinical scores as well as failure rates [15,18,34,44,68,116].…”

Aktuelle Nahttechniken zur Rekonstruktion der Rotatorenmanschette

“…Es konnte in mehreren biomechanischen Arbeiten bereits gezeigt werden, dass "Single-row-Rekonstruktionen" unter der Verwendung von modifizierten Nahttechniken vergleichbare biomechanische Ergebnisse erreichen konnten wie die getesteten "Double-row-Rekonstruktionen", sowohl in der maximalen Versagenslast, als auch bezüglich der Elongation unter zyklischer Belastung [24,25,[27][28][29][30][31][32]35].…”

“…Auch die "Transosseous-equivalent-" oder "Suturebridge-Technik" konnte biomechanisch im Vergleich zu Einreihenrekonstruktionen unter der Verwendung von modifizierten Nachtechniken nicht überzeugen [24,25,[27][28][29]. Darüber hinaus führen die Vorteile des "footprint coverage" aus biomechanischen Arbeiten bisher zu keiner signifikanten Verbesserung der klinischen Ergebnisse -weder in den klinischen Scores, noch in einer eindeutigen Reduktion der Rerupturrate [3,5,9,17,23,42].…”
