RESUMO

For the purpose of analyzing the influence of the freezing phenomenon and cryopreservation time over the biomechanical properties of tendons, the authors studied 40 Achilles tendons from 20 human cadavers. Each cadaver had two tendons removed, one of which was tested whilst fresh and its contralateral whilst frozen at - 85o C, for a period of six or 12 weeks. The trial items were submitted to tensile testing in order to analyze their biomechanical properties. The results were compared statistically using the T-Student method, with a significance ratio of 0.05, there being no significant difference between the frozen group and the fresh group
