Abstract
V nalogi je prikazan razvoj biomehaničega modela človeškega kolena za uporabo v numeričnih analizah z možnostjo aktivacije mišic. Za realni napetostno-deformacijski odziv modela potrebujemo natančne materialne lastnosti kolenskih ligamentov in podatke o poteku aktivacije mišic. Z izvedbo nateznih preizkusov v simuliranih fizioloških pogojih želimo pridobiti materialne lastnosti patelarnega ligamenta, z izvedbo izokinetičnih meritev in uporabo MC-zaznaval pa napetostni odziv glav štiriglave stegenske mišice. Rezultati nateznih meritev patelarnega ligamenta so primerljivi z drugimi raziskavami. Napetostni odziv MC-zaznaval ne odraža dejanskega poteka aktivacije mišic. Razvili smo aktivni numerični model kolena.

Title:Biomechanical model of the human knee at active loading
Abstract:
The goal of this thesis is the development of a biomechanical model of the human knee for use in numerical simulations with the option of muscle activation. For an accurate stress strain response of the model, we need accurate mechanical properties of the knee ligaments and function of muscle activation. We want to gather mechanical properties of the patellar ligament by means of tensile testing in simulated physiological conditions and measure the muscle activation response using the MC sensors in isokinetic measurements. The results of the patellar ligament tensile response are in the scope of other research findings. The MC sensor response does not represent isolated muscle activity. We have developed the active knee model that continues to evolve.

Keywords:knee, patellar ligament, muscle activation, numerical model, finite element, lower extremity
