Rotator cuff tears are increasing in frequency in the aging population and are a common issue seen by orthopaedic surgeons. In patients with large, multi-tendon rotator cuff tears or retears, treatment can be challenging. Failure rates of up to 90% have been reported for rotator cuff repair (RCR) of large, multi-tendon tears. Biological augmentation has been an area of interest because of the distinctly different biology of the repaired tendon compared with the native tendon. These biological differences affect the ultimate tensile properties of the repair and may contribute to gap formation and the high failure rate of repairs. RCR with allograft augmentation is a technique that shows potential benefit to healing and preventing retears. Arthroscopic augmentation of RCRs can be challenging. The technique described in this Technical Note illustrates a simple and easily reproducible method for augmenting RCRs with human acellular dermal allograft.
肩袖撕裂在老年人群中的发生率正在上升,是骨科医生常见的问题。对于大型、多肌腱肩袖撕裂或再撕裂的患者,治疗可能具有挑战性。据报道,大型、多肌腱撕裂的肩袖修复(RCR)失败率高达90%。由于修复后的肌腱与天然肌腱在生物学上有明显不同,生物增强一直是一个受关注的领域。这些生物学差异会影响修复的最终拉伸性能,并可能导致间隙形成和修复的高失败率。同种异体移植增强的RCR是一种显示出对愈合和预防再撕裂有潜在益处的技术。关节镜下增强RCR可能具有挑战性。本技术说明中描述的技术展示了一种用人类脱细胞真皮同种异体移植增强RCR的简单且易于重复的方法。
