PURPOSE
The purpose of this study was to compare the load-to-failure of different common suturing techniques with a new technique for the medial meniscus posterior root tear (MMPRT).
METHODS
Thirty porcine medial menisci were randomly assigned to three suturing techniques used for transtibial pullout repair of the MMPRT (n = 10 per group). Three different meniscal suture configurations were studied: the two simple suture (TSS) technique, the conventional modified Mason-Allen suture (MMA) technique, and the new MMA technique using the FasT-Fix combined with the Ultrabraid (F-MMA). The ultimate failure load was tested using a tensile testing machine.
RESULTS
The MMA and F-MMA groups demonstrated significantly higher failure loads than the TSS group (P = 0.0003 and P = 0.0005, respectively). No significant differences were observed between the MMA and F-MMA groups (P = 0.734).
CONCLUSIONS
The ultimate failure load was significantly greater in the F-MMA than the TSS group and similar to the conventional MMA technique.
目的
本研究的目的是比较不同常见缝合技术与一种用于内侧半月板后根撕裂（MMPRT）的新技术的失效负荷。
方法
30个猪内侧半月板被随机分配至用于MMPRT经胫骨拉出修复的三种缝合技术（每组n = 10）。研究了三种不同的半月板缝合构型：两种单纯缝合（TSS）技术、传统改良梅森-艾伦缝合（MMA）技术以及使用FasT-Fix联合UltraBraid的新型MMA技术（F-MMA）。使用拉伸试验机测试极限失效负荷。
结果
MMA组和F-MMA组的失效负荷显著高于TSS组（分别为P = 0.0003和P = 0.0005）。MMA组和F-MMA组之间未观察到显著差异（P = 0.734）。
结论
F-MMA组的极限失效负荷显著高于TSS组，且与传统MMA技术相似。
