Title: A comparison of the healing properties of rabbit Achilles tendon injuries at different levels. Author: Kuschner SH, Orlando CA, McKellop HA, Sarmiento A. Journal: Clin Orthop Relat Res; 1991 Nov; (272):268-73. PubMed ID: 1934743. Abstract: 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.[Abstract] [Full Text] [Related] [New Search]
