The aim of this study was to compare new knotless single-row and double-row suture anchor techniques with traditional transosseous suture techniques for different sized rotator cuff tears in an animal model.
The study included 56 cadaveric sheep shoulders. Supraspinatus cuff tears of 1 cm repaired with new knotless single-row suture anchor technique and supraspinatus and infraspinatus rotator cuff tears of 3 cm repaired with double-row suture anchor technique were compared to traditional transosseous suture techniques and control groups. The repaired tendons were loaded with 5 mm/min static velocity with 2.5 kgN load cell in Instron 8874 machine until the repair failure.
The 1 cm transosseous group was statistically superior to 1 cm control group (p=0.021, p<0.05) and the 3 cm SpeedBridge group was statistically superior to the 1 cm SpeedFix group (p=0.012, p<0.05). The differences between the other groups were not statistically significant.
No significant difference was found between the new knotless suture anchor techniques and traditional transosseous suture techniques.
本研究旨在通过动物模型，比较新型无结单排和双排缝合锚钉技术与传统骨内缝合技术对不同大小肩袖撕裂的治疗效果。
本研究纳入56个尸体羊肩标本。将采用新型无结单排缝合锚钉技术修复的1厘米大小的冈上肌肌腱撕裂，以及采用双排缝合锚钉技术修复的3厘米大小的冈上肌和冈下肌肌腱撕裂，与传统骨内缝合技术及对照组进行比较。在Instron 8874机器上，使用2.5 kgN的测力传感器以5毫米/分钟的静态速度对修复后的肌腱加载，直至修复失败。
1厘米大小的骨内缝合组在统计学上优于1厘米大小的对照组（p=0.021，p<0.05）；3厘米大小的SpeedBridge组在统计学上优于1厘米大小的SpeedFix组（p=0.012，p<0.05）。其他组之间的差异无统计学意义。
新型无结缝合锚钉技术与传统骨内缝合技术之间未发现显著差异。
