“…Thus, the entire set of modern endoprostheses for THR is divided into two subsets: cemented and cementless, each of which is represented by a wide range of product sizes that differ, among other things, in the materials from which the main components are made, including the femoral head and modular cup liner forming a friction pair. Currently, the following friction pairs are mainly used in modular endoprostheses for THR [28][29][30]:…”

“…The advantages and disadvantages of each of these pairs are described in the literature, for example [30]. Nevertheless, in the context of this article, it is necessary to note the main drawback inherent in all artificial friction pairs, which consists in the fact that, as a result of wear, a large number of the smallest particles from the materials of the pair accumulate in the periprosthetic tissues.…”

“…A systematic analysis of the observed complications allows us to conclude that in order to improve the quality of THR, it is necessary to develop navigational and robotic surgical technologies, minimally invasive surgery, manufacturing methods, and materials and designs of endoprostheses (including their friction pairs) [23,57]. From our point of view, therapy, rehabilitation and monitoring of the patient's condition in the perioperative period are also significant factors that require priority attention [30].…”

Since the end of the 19th and the beginning of the 20th centuries, technological equipment, implant designs (endoprosthesis) and the surgical technique of total hip replacement (THR) have been constantly improved and reached a high level of functionality and quality. Therefore, at present, THR is one of the most high-tech, reliable and popular surgical operations that allow a large number of people suffering from osteoarthritis and other serious diseases of the hip joint to return to an active lifestyle. At the same time, it is known that even operations at this level do not always guarantee the achievement of the desired result and can lead to various complications. The question arises: are there potential opportunities for creating an “ideal endoprosthesis” that allows one to perform an “ideal THR”? In this paper, based on a critical analysis of modern endoprosthesis designs for THR, technologies for their implantation and systemic postoperative complications, the most probable, according to the authors, ways of their development are formulated, which allow asymptotically approaching the “ideal”.

“…Numerous biomaterials are being developed for used in bearing of total hip prosthesis. Metals 4 , ceramics 5 , and polyethylene 6 materials are frequently employed in implant preparation. Due to their excellent wear resistance, bearing combination such as metal-on-metal 7 , metal-on-polyethylene 8 , ceramic-on-ceramic 9 , and ceramic-on-polyethylene 10 has been developed.…”

The single mobility bearing as a previous bearing design of total hip prosthesis has severe mobility constraints that can result in dislocation during Muslim (people who follow the Islam as religion) prayer movements, specifically shalat that requires intense movement. There are five intense movements (i.e., bowing, prostration, sitting, transition from standing to prostration, and final sitting) during Muslim prayer that may generate an impingement problem for patients with total hip prosthesis. In this work, textured dual mobility total hip prosthesis with two textured cases (i.e., textured femoral head and textured inner liner) are presented and their performances are numerically evaluated against untextured surface model during Muslim prayer movement. The concave dimple design is chosen for surface texturing, while for simulating femoral head materials, SS 316L and CoCrMo is choosen. To represent the real condition, three-dimensional computational fluid dynamics (CFD) coupled with two-way fluid–structure interaction (FSI) methods are employed to analyze elastohydrodynamic lubrication problem with non-Newtonian synovial fluid model. The main aim of the present study is to investigate the tribological performance on dual mobility total hip prosthesis with applied textured surface with concave dimple in femoral head and inner liner surface under Muslim prayer movements. It is found that applying surface texturing has a beneficial effect on the lubrication performance for some intense movements. The textured femoral head model performs better than textured inner liner model and untextured model (both femoral head and inner liner). The numerical results also indicate superior performance of CoCrMo femoral head compared to SS 316L femoral head. These findings can be used as a reference for biomedical engineers and orthopedic surgeons in designing and choosing suitable total hip prosthesis for Muslims makes they can carry out Muslim prayer movements like humans in general who have normal hip joints.
