INTRODUCTION
To compare the strength between the Achilles tendons repaired with the "Giftbox" and the Krackow techniques in New Zealand white rabbits post six weeks of tendon healing.
MATERIALS AND METHODS
Eight rabbits were randomized into Giftbox and Krackow groups. Tenotomy was performed on the Achilles tendon of one side of the lower limb and repaired with the respective techniques. The contralateral limb served as control. Subjects were euthanized six weeks post-operative, and both repaired and control Achilles tendons were harvested for biomechanical tensile test.
RESULTS
The means of maximum load to rupture and tenacity in the Giftbox group (156.89 ± 38.49 N and 159.98 ± 39.25 gf/tex) were significantly different than Krackow's (103.55 ± 27.48 N and 104.91 ± 26.96 gf/tex, both p = 0.043).
CONCLUSION
The tendons repaired with Giftbox technique were biomechanically stronger than those repaired with Krackow technique after six weeks of tendon healing.
简介
比较新西兰白兔跟腱修复后 6 周时“礼盒”法与 Krackow 法的腱强度。
材料与方法
8 只兔子随机分为礼盒组和 Krackow 组。一侧后肢跟腱行腱切断术并用相应技术修复。对侧肢体作为对照。术后 6 周处死所有动物，获取修复和对照跟腱行生物力学拉伸试验。
结果
礼盒组的最大断裂载荷和断裂韧性分别为（156.89±38.49N 和 159.98±39.25gf/tex），明显高于 Krackow 组（103.55±27.48N 和 104.91±26.96gf/tex，均 p=0.043）。
结论
跟腱修复后 6 周时，礼盒法修复的跟腱在生物力学上比 Krackow 法修复的更牢固。
