“…FG longitudinal and radial prostheses with a volume fraction exponent of zero (conventional material (Ti)) and three exhibited the minimum and maximum strain energies at the proximal part of the femur, respectively. These finding are compatible with the presented results for THR by Kuiper and Huiskes [19], Hedia et al [20,21], Gong et al [22], and Enab and Bondok [18] for THR. In the cemented THR, a part of the loads was absorbed by the cement layer by transferring the loads to the bone [11].…”

“…For example, the acetabular cup and femoral prostheses' head fabricated of FGM showed higher fracture toughness and wear resistance compared with that of their monolithic ceramic or metallic counterparts [16,17]. Enab and Bondok [18] conducted finite element analysis (FEA) on a tibia tray made by FGMs and found less stress shielding in the bony structures around the tibia try. Kuiper and Huiskes [19], Hedia et al [20,21], and Gong et al [22] presented the stress shielding and interface shear stresses reduction by employing FG prostheses in THR.…”

This study focused on developing a 3D finite element model of functionally graded femoral prostheses to decrease stress shielding and to improve total hip replacement performance. The mechanical properties of the modeled functionally graded femoral prostheses were adjusted in the sagittal and transverse planes by changing the volume fraction gradient exponent. Prostheses with material changes in the sagittal and transverse planes were considered longitudinal and radial prostheses, respectively. The effects of cemented and noncemented implantation methods were also considered in this study. Strain energy and von Mises stresses were determined at the femoral proximal metaphysis and interfaces of the implanted femur components, respectively. Results demonstrated that the strain energy increased proportionally with increasing volume fraction gradient exponent, whereas the interface stresses decreased on the prostheses surfaces. A limited increase was also observed at the surfaces of the bone and cement. The periprosthetic femur with a noncemented prosthesis exhibited higher strain energy than with a cemented prosthesis. Radial prostheses implantation displayed more strain energy than longitudinal prostheses implantation in the femoral proximal part. Functionally graded materials also increased strain energy and exhibited promising potentials as substitutes of conventional materials to decrease stress shielding and to enhance total hip replacement lifespan.

“…The appropriate design of femoral prostheses is complicated. Implants should be mechanically compatible with the host bone, and its material should tolerate harsh biological environments of the body . The mechanical compatibility of the prosthesis with the bone is a function of prosthetic stiffness.…”

Effect of Geometrical Parameters on the Performance of Longitudinal Functionally Graded Femoral Prostheses

This study aimed to assess the performance of different longitudinal functionally graded femoral prostheses. This study was also designed to develop an appropriate prosthetic geometric design for longitudinal functionally graded materials. Three-dimensional models of the femur and prostheses were developed and analyzed. The elastic modulus of these prostheses in the sagittal plane was adjusted along a gradient direction from the distal end to the proximal end. Furthermore, these prostheses were composed of titanium alloy and hydroxyapatite. Results revealed that strain energy, interface stress, and developed stress in the femoral prosthesis and the bone were influenced by prosthetic geometry and gradient index. In all of the prostheses with different geometries, strain energy increased as gradient index increased. Interface stress and developed stress decreased. The minimum principal stress and the maximum principal stress of the bone slightly increased as gradient index increased. Hence, the combination of the femoral prosthetic geometry and functionally graded materials can be employed to decrease stress shielding. Such a combination can also be utilized to achieve equilibrium in terms of the stress applied on the implanted femur constituents; thus, the lifespan of total hip replacement can be prolonged.

“…Finally, at direct contact areas of the prosthesis and bone, a bioactive material to reduce the micro-motions is suggested. The use of functionally graded biomaterials in medical prosthetics has been considered in recent researches (Sadollah and Bahreininejad, 2011;Gong et al, 2012;Enab and Bondok, 2013). Some works on the use of these materials in knee prostheses have also been reported in the literature (Bahraminasab et al, 2013a,b); however, the bioactivity that prevents micro-motions, the reduction in the effects of shielding stress, and establishing strength have not been sufficiently taken into consideration.…”

To Improve Total Knee Prostheses Performance Using Three-Phase Ceramic-Based Functionally Graded Biomaterials

et al. 2019

One of the common issues that occur after total knee replacement surgery is the aseptic loosening. The problem usually occurs after about 15 years from the surgery. The destructive effects of residual particles due to wear, the stress shielding effect, and micro-movements are the causative factors for this type of loosening. In this research, using the advantages of functionally graded biomaterials (FGBM), it is tried to design a prosthetic system that can reduce the above-mentioned effects. For this purpose, the materials used in the most important part of the prosthesis system, i.e., the femoral part are redesigned so that the bioactivity between the prosthesis and bone, and the stress applied to the adjacent tissues increase simultaneously. In addition, to reduce the effect of wear at contact areas, wear-resistant biocompatible ceramics such as alumina and zirconia are used. The value of stress at the bone-prosthesis interface and adjacent tissues is the most important parameters. Two types of three-phase ceramic-based FGBMs are recommended. The prosthesis with three-phase hydroxyapatite-titanium-zirconia has increased the average stress in the bone tissues around high-risk areas up to 71.8% with respect to a commonly used Cr-Co prosthesis. The result for the prosthesis with three-phase hydroxyapatite-titanium-alumina is up to 65%, respectively. At bone-prosthesis interfaces, an increase of 92% in the stress for both zirconia-based and alumina-based is seen. Briefly, the recommended FGBMs can improve the bone-prosthesis performance in all desired indices.
