Changes in Axial Compression Parameters of the Sutured Human Meniscal Horn Subjected to Axial Compression and Circumferential Traction: Experimental–Computational Analysis [English translation]

This work deals with the study of the influence of circumferential traction on sutured meniscal horns subjected to indentation tests, as well as the suitability of using material properties obtained from isolated compression tests versus those from combined load tests in finite element (FE) models subjected to combined loading. Non-destructive indentation tests were performed on 27 sutured human meniscal horns at three circumferential load levels: 0N, 10N and 20N. Eighty-four FE models were developed from one specimen with the same experimental setup and with experimentally obtained material properties at the different tensile states. Circumferential tension generated significant differences between the maximum force at indentation and the instantaneous modulus with respect to the state without circumferential loading. Simulations under combined loading provided more accurate results when using material properties obtained from tests under the same stress state.
