Journal ArticleDOI

Hip contact forces and gait patterns from routine activities.

TL;DR: The paper focuses on the loading of the femoral implant component but complete data are additionally stored on an associated compact disc that contains complete gait and hip contact force data as well as calculated muscle activities during walking and stair climbing and the frequencies of daily activities observed in hip patients.
Journal ArticleDOI

Musculo-skeletal loading conditions at the hip during walking and stair climbing.

TL;DR: The presented approach is considered as a useful means to determine valid conditions for the analysis of prosthesis loading, bone modeling or remodeling processes around implants and fracture stability following internal fixation.
Journal ArticleDOI

A survey of formal methods for determining the centre of rotation of ball joints.

TL;DR: A new method is proposed, the symmetrical CoR estimation or SCoRE, in which the coordinates of the joint centre must only remain constant relative to each segment, thus not requiring the assumption that one segment should remain at rest.
Journal ArticleDOI

Tibio-femoral loading during human gait and stair climbing.

TL;DR: The data demonstrate that high contact and shear forces are generated during weight bearing combined with knee flexion angles greater than approximately 15° and Clinically, the conditions that produce these larger contact forces should be avoided during post‐operative rehabilitation.
Journal ArticleDOI

Influence of muscle forces on femoral strain distribution

TL;DR: The importance of an ensemble of muscle forces to reproduce a physiological strain distribution in the femur is demonstrated by using a finite element model to calculate stresses and strains of a femur with all thigh muscle and joint contact forces.
