Abstract (sommario):

A new generation of hip replacements has been designed incorporating compliant layers to promote fluid film lubrication when the joints are implanted in patients. Tests in the Durham hip function simulator show that the friction in these joints is up to an order of magnitude lower than in currently used prostheses, and because this is due to complete separation of the rubbing surfaces, wear ought to be vastly reduced. Experiments have shown that the best results are achieved with compliant surfaces of hardness between 4 and 8 N/mm2. Such surfaces produce coefficients of friction of the order o

Abstract (sommario):

With the increasing market demand for artificial hip joints, total hip joint replacement has gradually become an effective means of treating a series of hip joint diseases. In order to improve the service life of artificial hip joints, some new artificial hip joint materials, including polyetheretherketone (PEEK) and carbon fiber reinforced polyetheretherketone (CFR-PEEK), have been developed. In this paper, pin-on-plate wear tests under different cross-shear ratios and contact pressures were carried out to study the wear mechanism and worn surface topography of PEEK and CFR-PEEK.

Abstract (sommario):

An extremely small roughness of constant height magnitude is considered on the femoral head of an artificial hip joint in order to determine the consequences of various regular shapes and clearances on the mechanical performance of this hip prosthesis via a properly coupled finite and boundary element method. In addition, different material combinations typical for widely used hard-on-hard and hard-on-soft hip joint replacements are also taken into account. By analysing the calculated pressure distribution and contact area between the femoral head and the acetabular cup in frictionless dry con

Abstract (sommario):

Hip simulators are designed to reproduce the forces and motion patterns of normal walking. In vivo demands on total hip replacements, however, are varied and often more severe than normal walking conditions. It is these severe conditions that often lead to implant failure. This is clinically based research aimed at understanding some of the more severe conditions in hips and the effect that these have on the performance of the total hip replacement. The polyethylene liner can act as a pump in an acetabular component, forcing fluid and wear particles through the holes to the retroacetabular bon

Abstract (sommario):

The excellent hip function and potential degeneration are closely linked with the unique structure of the joint cartilage that is principally composed of a solid phase and a fluid phase. Once damaged, the joint may need to be replaced by prosthesis in order to restore function in hip kinematics and kinetics. However, to what extent this can be achieved has yet to be quantified. On the other hand, the role of fluid pressurisation which plays in hip function has been poorly understood. The aim of this thesis was to address these issues. To evaluate the gait abnormality, particularly in terms of

Abstract (sommario):

The aim of this thesis was to determine if the size of the femoral head can influ-ence corrosion at the head-neck taper interface of total hip arthroplasty (THA) prosthe-ses. A hypothesis was developed that large head sizes could result in a greater toggling torque at the head-neck taper interface by increasing the distance between the centre of the femoral head to the centre of the neck taper. This could result in increased micromotion and deteriorate the passive oxide film along the head-neck taper interface; thus, making the taper interface vulnerable to corrosion.

Abstract (sommario):

Hip joint is one of the most important human joints that should be fully understood. The present research work aims at improving the tribological performance of the human artificial hip joint prostheses to help in producing reliable ones using design charts. An elasto-hydrodynamic model of the hip joint is proposed and numerical solution of the governing equations using finite difference technique is used to predict the elasto-hydrodynamic behavior of such joint. Parametric study has been conducted and results have shown that, thicker cup gives better tribological performance and the increase

Abstract (sommario):

The occurrence of primary and revision total hip and knee arthoplasty in the United States is increasing [1] due to several factors which include aging population and longer life expectancies [2]. The hip joint is one of the most commonly replaced joints with more than 120,000 artificial hip joints being implanted in the United States [3]. Complications associated with hip replacements include aseptic failure and prosthetic-joint infection [4]. Implant failure is known to cause significant morbidity, pain on weight-bearing, and increased health care costs [2, 5].

Some open questions raised by the reaction of tissue on particles require the knowledge of the acting wear mechanisms. These have to be clarified within the macro-, micro-, and nanoscale. Thus, this contribution focuses on the wear mechanisms of hard-hard artificial hip joints which have been verified to act both in clinical application and both during laboratory simulation. Some aspects of novel developments will be discussed on the basis of these findings.

This paper investigates swing-phase cavitation formation and collapse in a novel artificial hip joint using a well-established transient mass-conserving finite element cavitation algorithm. Elastic elements and ellipsoidal cup surface geometry are incorporated into the new design to promote and enhance ‘squeeze-film’ action over ‘wedge-film’ action employed in conventional artificial hip joints. During the swing phase of the gait cycle, the lubricant film undergoes cavitation from normal separation of ball and cup surfaces. Reformation of a complete lubricant film is predicted over a wide rang

Abstract The development of the hip prosthesis is a result of extensive collaboration between the medical and engineering fields. Although the technology to replace ailing human joints with artificial replicas is quite advanced, these remarkable advances require additional attention. In particular, extending the service life of a hip prosthesis is a primary consideration. An artificial hip joint may require revision surgery due to a number of contributions, one of which is extensive wear. Within the first few years following hip implantation, high amounts of wear particles form due to the cont

The Phan-Thien Tanner (PTT) model is one of the most widely used rheological models. It can properly describe all the common characteristics of viscoelastic non-Newtonian fluids. Synovial fluid of human joints, which also lubricates artificial joints, is well known to be highly viscoelastic. Thus it is reasonable to attempt to describe such joint behavior using non-Newtonian flow models. Modeling the geometry of the total hip replacement, the PTT model is applied in spherical coordinates to a thin confined fluid film.

Abstract Total artificial joint replacements are one of the most effective treatments for arthritis. Artificial joints are used to replace damaged cartilage and act as low-friction articulating materials in joints. During normal human walking, some of the materials used for artificial knee and hip replacements are subjected to both sliding articulation (relative motion) and cyclic loading. A common example is the CoCrMo alloy femoral surface of an artificial knee that articulates against an ultra-high-molecular-weight-polyethylene (UHMWPE) component.
