Rotator cuff tear is one of the most common upper-extremity pathologies and often requires repair. The pursuit of optimal arthroscopic rotator cuff repair has spurred numerous technical innovations and stitch-pattern refinements. First, the double-pulley construct can increase tendon-bone compression and provide a joint seal. Second, the rip-stop configuration can reduce the possibility of tendon cut-through and improve the biomechanical properties of the fixation. Thus, an alternative method is introduced by incorporating both techniques simultaneously into arthroscopic suture-bridge repair, in which the medial double-pulley construct assumes the function of a rip-stop. This method may improve the biology of tendon healing and reduce the retear rate after rotator cuff repair.
肩袖撕裂是最常见的上肢疾病之一，通常需要进行修复。对最佳关节镜下肩袖修复的追求推动了众多技术创新和缝线模式的改进。首先，双滑车结构可以增加肌腱与骨的压缩力并提供关节密封。其次，防撕裂结构可以降低肌腱切断的可能性并改善固定的生物力学性能。因此，引入了一种替代方法，即将这两种技术同时纳入关节镜下缝合桥修复，其中内侧双滑车结构承担防撕裂的功能。这种方法可能会改善肌腱愈合的生物学过程并降低肩袖修复后的再撕裂率。
