Rabbit Achilles tendons were transsected at the muscle-tendon junction (Group 1), midtendon (Group 2), or at the calcaneus insertion (Group 3). Treatment consisted of immobilization in a long leg cast without surgical repair. The contralateral leg served as a control. Tensile testing was performed at four weeks. Groups 1 and 2 failed most often in the proximal muscle rather than at the healing site. In contrast, Group 3 failed more often at the healing site than in the muscle and was statistically superior to Groups 1 and 2 with respect to strength and stiffness. Statistically, control specimens showed failure at the musculotendinous junction at greater loads and were stiff compared to the experimental groups.
将兔跟腱在肌腱与肌肉交界处（第1组）、肌腱中部（第2组）或跟骨附着处（第3组）横断。治疗方法为长腿石膏固定，不进行手术修复。对侧腿作为对照。四周后进行拉伸试验。第1组和第2组大多在近端肌肉处而非愈合部位失效。相比之下，第3组在愈合部位失效的情况比在肌肉处更常见，并且在强度和刚度方面在统计学上优于第1组和第2组。从统计学上看，对照样本在更高负荷下在肌腱与肌肉交界处失效，并且与实验组相比更硬。
