“…One of the main reasons for the necessity to conduct reimplantation procedures is the mechanical destruction of the elements of the artificial bio-bearing. For various combinations of friction pairs used in endoprostheses, the elements made of UHMW-PE polyethylene are most frequently damaged [13,14].…”

The influence of dynamic loads resulting from human motor activity and electrocorrosion inside the human body on the strength parameters of artificial joint elements has not yet been investigated. Hip joint arthroplasty is the most common surgical procedure in the world that allows doctors to remove pain and restore motor skills in people with severe hip diseases, after accidents, and in the elderly. Based on the reports, this article assesses changes in the number of implanted endoprostheses in the years 2005–2019 and determines the trends and estimated changes in the number of implanted hip prostheses in the following decades. The study assesses changes in selected strength parameters of UHMW-PE polyethylene inserts of hip joint endoprostheses during their use in the human body. The research was carried out on appropriately collected samples from UHMW-PE cups removed from the human body with a known history and lifetime from 4 to 10 years. Patients’ body weight ranged from 735 [N] to 820 [N], and the declared physical activity was similar in the entire research group. As part of the research, the values of changes in dynamic modules and the mechanical loss coefficient were determined in relation to the share of the crystalline and amorphous phases of artificial UHMW-PE cups, removed from the human body after different periods of exploitation under similar operating conditions. The analysis of selected strength parameters was performed at a temperature of 40 °C, which corresponds to the working conditions inside the human body. On the basis of numerical studies, the influence of changes in material parameters on the deformation of the artificial acetabulum during the patient’s motor activity, which is one of the causes of fatigue destruction, was determined.

“…However, this should be done with eyes ‘wide open’ and without ignoring, de‐emphasizing or dismissing XLPE, at least in their literature review. Similar comments can be made with regard to retrieval studies [2] and studies proposing theoretical or analytical procedures [3, 4]. It seems clear to the current author that XLPE is the new gold (reference) standard bearing material for THA, which means that the biotribological and clinical performance of any other bearing material should be compared with it.…”

“…A few research studies expressed engineering concerns regarding the use of XLPE in THA or did not find convincing clinical support for its use in place of CPE. This was also evident from studies mentioned in the Introduction [2][3][4]. Thus, despite the overwhelming use of XLPE, the debate mentioned by Jasty et al [18] in 2005 is apparently not over.…”

Conventional polyethylene is not used much in total hip arthroplasty (THA); it has been supplanted by oxidation-resistant cross-linked polyethylene (≥50 kGy irradiation). However, studies persist that de-emphasize or ignore cross-linked polyethylene. A selective literature review is used briefly to present the early use of conventional polyethylene and its implication in wear particle-induced osteolysis leading to premature revision surgeries. The current situation is established based on Australian registry data and other studies that advocate the use of cross-linked polyethylene in preference to conventional polyethylene. Although some studies suggest caution in using cross-linked polyethylene, overall it is strongly supported. In the author's opinion, cross-linked polyethylene is the new reference standard bearing material in THA.This is an open access article under the terms of the Creative Commons Attribution-NonCommercial-NoDerivs License, which permits use and distribution in any medium, provided the original work is properly cited, the use is non-commercial and no modifications or adaptations are made.

“…In any case, Figure 9b shows that this lateral area is not correlated with microhardness and therefore with plastic deformation. Creep deformation could be the mechanical property involved in the presence of this material above the base line, according to the study of PE acetabular cups of retrieved prostheses (Choudhury et al, 2018;Kumakura et al, 2009). In our opinion, the material at the edges of the wear (Figure 7h) seems more like accumulated material dislodged from the track and then attached to the lateral parts, than a creep effect, although both mechanisms could be operating.…”
