背景：全内半月板修复无需额外切口，降低神经血管损伤风险。生物力学测试可以帮助描述全内装置使用的效果。假设：4种周围半月板修复技术和3种不同设备之间没有组间差异。研究设计：实验室对照研究。方法：将同等大小的半月板与附着胫骨随机分为4组，每组8例，分别为：1组，Fast-Fix，采用0号编织涤纶缝线；第2组，由内向外修复，采用2-0编织涤纶缝线；第3组，序贯采用0号超高分子量聚乙烯（UHMWPE）连续“N”形缝合；第4组，连续使用中断配置的0号UHMWPE缝线。放置在夹钳中后，试样进行5 - 20 N 10次循环（0.1 Hz）的预处理，500次5 - 20 N （0.5 Hz）的次最大加载循环，以及12.5 mm/s的加载-失效测试。在10次预处理循环和10次、100次和500次次最大加载循环后暂停30秒，可以拍摄用于间隙测量的数字照片。记录故障模式。结果：与1、4组相比，3组试件承受的破坏载荷更大(P
Background: All-inside meniscus repair eliminates the need for an extra incision and decreases neurovascular injury risk. Biomechanical testing can help delineate the efficacy of all-inside device use.Hypothesis: There would be no group differences between 4 peripheral meniscus repair techniques and 3 different devices tested.Study Design: Controlled laboratory study.Methods: Equivalent-sized menisci with attached tibiae were randomly assigned to 1 of 4 test groups (8 specimens each), as follows: group 1, Fast-Fix using No. 0 braided polyester suture; group 2, inside-out repair using 2-0 braided polyester suture; group 3, Sequent using No. 0 ultra-high molecular weight polyethylene (UHMWPE) suture in a continuous "N" configuration; and group 4, Sequent using No. 0 UHMWPE suture in an interrupted configuration. After placement in a clamp, specimens underwent preconditioning from 5 to 20 N for 10 cycles (0.1 Hz), 500 submaximal loading cycles from 5 to 20 N (0.5 Hz), and load-to-failure testing at 12.5 mm/s. A 30-second pause after 10 preconditioning cycles and after 10, 100, and 500 submaximal loading cycles enabled digital photographs to be taken for gapping measurements. Failure mode was recorded.Results: Specimens in group 3 withstood greater failure loads than did those in groups 1 and 4 (P
