Evaluation of a geometry-based knee joint compared to a planar knee joint

Abstract

Today neuromuscular simulations are used in several fields, such as diagnostics and planing of surgery, to get a deeper understanding of the musculoskeletal system. During the last year new models and datasets have been presented which can provide us with more in-depth simulations and results. The same kind of development has occurred in the field of studying the human knee joint using complex three dimensional finite element models and simulations. In the field of musculoskeletal simulations, no such knee joints can be used. Instead the most common knee joint description is an idealized knee joint with limited accuracy or a planar knee joint which only describes the knee motion in a plan. In this paper, a new knee joint based on both equations and geometry is introduced and compared to a common clinical planar knee joint. The two kinematical models are analyzed using a gait motion, and are evaluated using the muscle activation and joint reaction forces which are compared to in-vivo measured forces. We show that we are able to predict the lateral, anterior and longitudinal moments, and that we are able to prediction better knee and hip joint reaction forces.

Loads in the hip joint during physically demanding occupational tasks: A motion analysis study

“…Still the 1 DOF knee joint is widely used as the standard configuration for the simulation software. It is possible that the forces in the hip joint are slightly overestimated as a consequence of the simplified knee joint (Sandholm et al, 2011).…”

Gender effect on the scapular 3D posture and kinematic in healthy subjects

“…The differences of the kinematic between men and women are probably the consequence of various parameters. Musculoskeletal modelling (Damsgaard et al, 2006;Delp et al, 2007;Sandholm et al, 2011) may facilitate the investigation of the origin of these differences. Indeed, musculoskeletal modelling is a mechanical description of (at least) bony segments, joints and muscles.…”

The Morphometry of Soft Tissue Insertions on the Tibial Plateau: Data Acquisition and Statistical Shape Analysis

“…Most prior knee models employed the subject-specific geometry of bone and soft tissues from imaging data (e.g., CT and/or MRI) [46]–[48]. It can however be challenging to obtain accurate shape and location information for the ligament insertion sites and meniscal root attachments from MRI: specific MRI sequences and configurations may be required for different tissue structures [6], [37], [49].…”
