“…21 Suture-tendon cut through is usually considered the weakest link of the tendon-to-bone RCR and therefore one of the most important reasons for failure in aRCR, 12,22 and abrasiveness of the suture material used may be an essential biomechanical factor. 15,16,23 Contrary to observations of previously published studies, 15,17,19,23 we could not find significantly less tendon cut through of tapes versus sutures. However, our findings may be related to the high number of tapes tested in this study, which have shown considerably and significantly different results.…”

“…A further weakness of this in vitro study is that we did not perform the tests in an aqueous test setup, which could have had a potential beneficial effect on the results of the Dynacord sutures. 15 However, we decided to test all tapes and sutures under standardized conditions to provide adequate comparability of all products, as performed in previous biomechanical studies. 6 , 17 , 19 , 26 To reduce the risk of operator bias, all knots were tied in a standardized open fashion by an experienced shoulder surgeon.…”

“…2 Dynacord suture (DePuy Mitek, Raynham, MA) was introduced, and less tendon cut through was found compared with FiberWire. 15 Dynacord incorporates a silicone- and salt-filled core within a UHMWPE sheath. 15 Another popular high-strength suture is Ultrabraid (Smith & Nephew, Andover, MA), which has previously been shown to be less abrasive than FiberWire.…”

“…However, this study was performed on an acute rotator cuff tear model. To date, biomechanical comparisons of suture cut-through (13), the influence of knot location (14), and the suture absorbability (7) of different suture materials in acute rotator cuff healing have been studied; however, whether the type of suture material used in surgery would affect chronic rotator cuff healing on histological and molecular levels remains unknown. Therefore, this study aims to compare the healing effect of repair with two different suture materials, specifically Ethibond and Ultrabraid, at different intervals (at two and six weeks after repair) using histologic and western blot analysis.…”

Background. Previous studies have evaluated the biomechanical, histological, and clinical effects of rotator cuff repair with different suture materials. However, a histological and western blot analysis after repair comparing nonabsorbable polyester and polyethylene suture materials in a chronic rotator cuff tear model has not been conducted in any previous studies. The aim of this study is to evaluate the effect the two different suture materials, specifically Ethibond and Ultrabraid, have on repair based on a histological evaluation and protein expression by means of a western blot analysis. Methods. Twenty-six rabbits were included in the study. Two rabbits served as normal controls (control group). A bilateral tenotomy of the subscapularis tendon was performed in the remaining 24 rabbits. Six weeks after the tenotomy, the animals were randomly divided into four repair groups (five rabbits in each group) according to the suture material used and the sacrifice time (Ultrabraid two weeks after repair, Ethibond two weeks after repair, Ultrabraid six weeks after repair, and Ethibond six weeks after repair). Two sham-operated groups with two rabbits each were sacrificed at eight and 12 weeks after the tenotomy without repair. Both shoulders of all the animals were used for a western blot (collagen type 1-3, MMP-2, TGF-beta-1, IGF-1, COX-2) analysis and a histological evaluation (fibrocartilage formation, inflammation, vascularisation, collagen density). Results. All groups showed minimal-to-mild histological changes irrespective of the type of suture material used. There was no statistically significant difference in histological scores (p > 0.05). Fibrocartilage formation was greater at six weeks in the polyester suture repair groups without statistical significance (p > 0.05). Collagen type 1-3, MMP-2, TGF-beta-1, IGF-1, and COX-2 were significantly upregulated at two weeks compared to six weeks after repair (p < 0.05). Protein expression levels were statistically significantly higher in the Ultrabraid groups compared to the Ethibond groups (p < 0.05). Conclusions. Changes in the expression of the markers related to rotator cuff healing were demonstrated when repairing with different suture materials, with these being in favour of polyester sutures; however, the histological findings are similar. This finding could influence the design of new suture materials.

Aging‐Related Rotator Cuff Tears: Molecular Mechanisms and Implications for Clinical Management

Shoulder pain and disabilities are prevalent issues among the elderly population, with rotator cuff tear (RCT) being one of the leading causes. Although surgical treatment has shown some success, high postoperative retear rates remain a great challenge, particularly in elderly patients. Aging‐related degeneration of muscle, tendon, tendon‐to‐bone enthesis, and bone plays a critical role in the development and prognosis of RCT. Studies have demonstrated that aging worsens muscle atrophy and fatty infiltration, alters tendon structure and biomechanical properties, exacerbates enthesis degeneration, and reduces bone density. Although recent researches have contributed to understanding the pathophysiological mechanisms of aging‐related RCT, a comprehensive systematic review of this topic is still lacking. Therefore, this article aims to present a review of the pathophysiological changes and their clinical significance, as well as the molecular mechanisms underlying aging‐related RCT, with the goal of shedding light on new therapeutic approaches to reduce the occurrence of aging‐related RCT and improve postoperative prognosis in elderly patients.
