Strength tests of human tendons following prolonged storage

Abstract

: This work presents investigations into tendons of human origin used for the reconstruction of ligaments in the knee joint. The scope of tests included a static tensile test using strength testing machine MTS Criterion Model 43 (MTS Systems, Eden Prairie, MN, USA). Samples of long peroneal muscle (peroneus longus) tendons and short peroneal muscle (peroneus brevis) tendons were subjected to testing. The main objective of the research was to determine mechanical properties of tendons after a prolonged period of storage, which lasted 9 years. The following mechanical properties of tendons were obtained: maximum breaking force Fmax , maximum stress σmax [MPa] and Young’s modulus E [MPa].
