Repair of the rotator cuff requires secure reattachment, but large chronic defects cause osteoporosis of the greater tuberosity which may then have insufficient strength to allow proper fixation of the tendon. Recently, suture anchors have been introduced, but have not been fully evaluated. We have investigated the strength of suture-to-anchor attachment, and the use of suture anchors in repairs of the rotator cuff either to the greater tuberosity or the lateral cortex of the humerus. The second method gave a significant increase in the strength of the repair (p = 0.014). The repairs were loaded cyclically and failed at low loads by cutting into bone and tendon, casting doubt on the integrity of the repair in early mobilisation after surgery. Repairs with suture anchors did not perform better than those with conventional transosseous attachment.
肩袖修复需要牢固的重新附着，但大的慢性缺损会导致大结节骨质疏松，进而可能没有足够的强度来实现肌腱的妥善固定。最近，缝合锚钉已被引入，但尚未得到充分评估。我们研究了缝合线与锚钉的附着强度，以及在肩袖修复中使用缝合锚钉将其固定于大结节或肱骨外侧皮质的情况。第二种方法显著提高了修复强度（p = 0.014）。修复部位进行循环加载，在低负荷时因切入骨和肌腱而失效，这使人对术后早期活动时修复的完整性产生怀疑。使用缝合锚钉的修复效果并不比传统的经骨附着修复更好。
