To compare mechanical stability between a novel polypropylene mesh repair (Mesh), a modified 3-loop pulley suture (Suture), and a combination of the techniques (Suture+Mesh) for the repair of distal canine Achilles' tendon ruptures.
In vitro mechanical evaluation.
Cadaveric canine Achilles' tendon/calcaneus units (n=34).
Constructs were loaded under tension to failure in a materials testing machine with synchronized kinematic analysis. Ultimate load to failure, global construct stiffness, and force required to reach 1 and 3 mm gap formation was recorded.
Ultimate load to failure was greatest for the Suture+Mesh group and lowest for the Suture group. The Suture+Mesh technique afforded a significantly greater global stiffness than the Suture or Mesh treatments. Force to generate 1 and 3 mm gap formation was greatest with the Suture group.
The Suture+Mesh group had the highest ultimate load to failure and afforded the greatest global stiffness though it had no added benefit to resist local gap formation at the repair.
Achilles' ruptures repaired with suture can be augmented with mesh to increase the ultimate load to failure, but as currently tested, there was a decrease in resistance to gap formation At this time we cannot recommend Mesh or the Suture+Mesh techniques without further testing.
比较一种新型聚丙烯网片修复术（网片组）、改良三环滑轮缝合术（缝合组）以及两种技术联合应用（缝合 + 网片组）修复犬跟腱远端断裂时的力学稳定性。
体外力学评估。
尸体犬跟腱/跟骨单元（n = 34）。
在材料试验机上对构建物进行拉伸加载直至破坏，并同步进行运动学分析。记录破坏时的极限载荷、整体构建物刚度以及形成1毫米和3毫米间隙所需的力。
缝合 + 网片组的破坏极限载荷最大，缝合组最小。缝合 + 网片技术提供的整体刚度显著高于缝合组或网片组。缝合组形成1毫米和3毫米间隙所需的力最大。
缝合 + 网片组具有最高的破坏极限载荷和最大的整体刚度，尽管在修复处抵抗局部间隙形成方面没有额外益处。
用缝合修复的跟腱断裂可用网片增强，以增加破坏极限载荷，但按照目前的测试，抵抗间隙形成的能力会降低。目前在没有进一步测试的情况下，我们不能推荐网片或缝合 + 网片技术。
