A parametric analysis of fixation post shape in tibial knee prostheses.
TL;DR: A 3D finite element model developed to study bone and interface stresses for four different tibial prosthesis designs indicates that stress distribution is affected by the incorporation of anisotropy and spatial variation of bone properties.

A three-dimensional finite element stress analysis for tunnel placement and buttons in anterior cruciate ligament reconstructions
TL;DR: A three-dimensional finite element model of stresses in a surgically altered femur and tibia incorporated a novel approach in implementing orthotropic and inhomogeneous bone properties and non-uniform distributed loading to compare well with experimental principal compressive strains from the literature.

TL;DR: A semi-automatic non-uniform rational B-spline (NURBS) technique is introduced to construct knee bone geometries from computed tomography (CT) images using a combination of edge extraction and CAD surface generation.

Representation of bone heterogeneity in subject-specific finite element models for knee
TL;DR: An innovative application of an image processing technique in the context of material properties modeling was introduced to facilitate an objective grouping strategy, which gathered together bone based not only on density but also on location thus capturing the natural variation of bone density seen in CT images.

Investigation of a hybrid method of soft tissue graft fixation for anterior cruciate ligament reconstruction.
TL;DR: Assessment of the initial pullout force, stiffness of fixation, and failure modes for a novel hybrid fixation method combining periosteal and direct fixation using porcine femoral bone indicates that initial pull out force of soft tissue grafts can be increased by using the suggested novel hybrids method.
