“…Besides biomechanical improvements (Lorbach et al, 2008;Mahar et al, 2007;Pauly et al, 2010), recent approaches have suggested an influence of growth factors on tendon cell behaviour and their potential value in rotator cuff repair.…”

“…To improve outcome results, biomechanical approaches for new surgical techniques have led to increased use of strong synthetic materials in order to reattach the torn tendon stump (Mahar et al, 2007;Lorbach et al, 2008;Pauly et al, 2010). However, the assumption of tissue damage and tendon strangulation through strong tissue adaption to the bony insertion is possible and might even deteriorate regeneration (Gerber et al, 1994;Flatow, 1996).…”

Rotator cuff tears are common soft tissue injuries of the musculoskeletal system that heal by formation of repair tissue and may lead to high retear rates and joint dysfunction. In particular, tissue from chronic, large tendon tears is of such degenerative nature that it may be prone to retear after surgical repair. Besides several biomechanical approaches, biologically based strategies such as application of growth factors may be promising for increasing cell activity and production of extracellular tendon matrix at the tendon-to-bone unit. As a precondition for subsequent experimental growth factor application, the aim of the present study was to establish and characterize a human rotator cuff tendon cell culture.Long head biceps (LHB)-and supraspinatus muscle (SSP)-tendon samples from donor patients undergoing shoulder surgery were cultivated and examined at the RNA level for expression of collagen type-I, -II and -III, biglycan, decorin, tenascin-C, aggrecan, osteocalcin, tenomodulin and scleraxis (by Real-time PCR). Finally, results were compared to chondrocytes and osteoblasts as control cells.An expression pattern was found which may reflect a human rotator cuff tenocyte-like cell culture. Both SSP and LHB tenocyte-like cells differed from chondrocyte cell cultures in terms of reduced expression of collagen type-II (p≤0.05) and decorin while higher levels of collagen type-I were seen (p≤0.05). With respect to osteoblasts, tenocytelike cells expressed lower levels of osteocalcin (p≤0.05) as well as tenascin C, biglycan and collagen type-III. Expression of scleraxis, tenomodulin and aggrecan was similar between all cell types.This study represents a characterization of tenocytelike cells from the human rotator cuff as close as possible. It helps analyzing their biological properties and allows further studies to improve production of tendon matrix and osteofibroblastic integration at the tendon-bone unit following tendon repair.

“…These advantages ultimately have been shown to lead to greater structural integrity of the cuff repair. [17][18][19][20][21] Despite the plethora of evidence that the double-row technique is anatomically and biomechanically superior to single-row and transosseous, results regarding clinical outcomes remains equivocal. Three Level I studies by Franceschi et al, 22 Burks et al, 23 Recent meta-analyses report that single-row repairs result in higher rates of retear than double-row techniques (25.9% vs 14.2%, P < .001), 25 with double-row methods demonstrating a greater degree of structural healing than single-row.…”

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.
