缝线-肌腱界面被证明是修复的肩袖的薄弱点。开发了一种双重防撕裂（DRS）技术，以增强缝线-肌腱界面的强度。本研究的第一个目的是比较补片缝线与临床常用的2号FiberWire（FW）之间的缝线-肌腱界面强度。第二个目的是使用典型的缝合桥（SB）和DRS技术比较网状缝线和2号FiberWire之间肩袖修复的生物力学性能。将18只猪肩胛下肌腱（SST）随机分配至补片肌腱组和FiberWire肌腱组。使用补片缝线或FiberWire将一个缝线环穿过SST。将32例冈下肌肌腱（IST）随机分为4组：SB-Mesh组：SB技术与Mesh缝线，SB-FW组：SB技术与FiberWire，DRS-Mesh组：DRS技术与Mesh缝线，DRS-FW组：DRS技术与FiberWire。所有修复后的试件均进行了失效试验。比较失效模式、产生3 mm间隙的载荷、失效载荷和刚度。在失效载荷、刚度和极限应力方面，网片-肌腱组和FiberWire-肌腱组之间没有显著差异。当使用相同的技术时，与FiberWire相比，使用网状缝线修复的肩袖具有相似的载荷，以产生3 mm的间隙、失效载荷和刚度。当使用相同缝线时，DRS技术产生3 mm间隙形成的载荷和失效载荷显著高于SB技术。无论采用何种修复技术，使用补片缝线的修复失效强度和刚度均与FiberWire缝线相似。然而，当使用相同的缝线材料时，DRS技术的修复强度明显强于SB技术。
The suture-tendon interface turned out to be the weak point of a repaired rotator cuff. A double rip-stop (DRS) technique was developed to enhance the strength of the suture-tendon interface. The first aim of this study was to compare the suture-tendon interface strength between mesh suture and the No. 2 FiberWire (FW), which is commonly used in the clinic. The second aim was to compare the biomechanical properties of rotator cuff repair between mesh suture and No. 2 FiberWire using a typical suture-bridge (SB) and DRS techniques. Eighteen porcine subscapularis tendon (SST) was randomly assigned to the Mesh-tendon group and FiberWire-tendon group. A single suture loop was passed through the SST with a Mesh suture or FiberWire. Thirty-two infraspinatus tendons (ISTs) were randomly assigned to four groups: SB-Mesh group: SB technique with Mesh suture, SB-FW group: SB technique with FiberWire, DRS-Mesh group: DRS technique with Mesh suture, and DRS-FW group: DRS technique with FiberWire. All repaired specimens were underwent failure testing. Failure modes, load to create a 3-mm gap, failure load, and stiffness were compared. There were no significant differences between the Mesh-tendon group and FiberWire-tendon group regarding the failure load, stiffness, and ultimate stress. When the same technique was used, the rotator cuff repaired with a mesh suture had the similar load to create a 3-mm gap, failure load, and stiffness compared with FiberWire. When the same suture was used, the DRS technique had a significantly higher load to create a 3-mm gap formation and failure load compared with the SB technique. The repair failure strength and stiffness using the mesh suture were similar to the FiberWire suture regardless of the repair techniques. However, the repair strength in the DRS technique was significantly stronger than the SB technique when the same suture material was used.
