“…The results showed that independent of kinematic conditions, the MoM combination exhibits the highest friction; however, this effect was significant mainly under negative sliding, when the friction at the end of the experiment reached almost 0.6. By contrast, the lowest friction was detected for MoP and CoP, while in the case of CoP, the friction level was less than 0.1, particularly around 0.05 for the dominant period of the experiments, which is in a good correlation with previous observations [ 11 , 19 , 20 ]. CoC frictional behaviour was found to be somewhere between, while the friction reached about 0.25.…”

“…The last point arising could be the effect of temperature on frictional behaviour. However, an increase of temperature of around 15 °C should not cause any change in terms of lubrication performance [ 18 ], and also conformational changes potentially influencing the results [ 11 ] are not expected. Considering the aforementioned limitations, the motivation for future study should be the necessity of applying complex model fluids containing all the synovial constituents together with attention to the real conformity of rubbing surfaces.…”

“…The authors showed that hydrophilic nature of the surfaces supports adsorption of the proteins in a native state, forming thicker lubricating film leading to lower friction between the components. An extensive investigation of the effect of model fluid composition on CoF dependent on kinematic conditions was provided in our previous study [ 11 ]. Reciprocating pin-on-plate (metal-UHMWPE) test was conducted, showing that the kinematic conditions have a crucial impact on the conformational changes of proteins, thus influencing frictional behaviour of the contact pair.…”

“…The opposite behaviour occurred at higher loads. Based on the above references [ 11 , 12 ], it can be concluded that friction between the rubbing surfaces is affected by both kinematic and loading conditions.…”

The paper introduces an experimental investigation of frictional behaviour of materials used for joint replacements. The measurements were performed using a ball-on-disc tribometer, while four material combinations were tested; metal-on-metal, ceramic-on-ceramic, metal-on-polyethylene, and ceramic-on-polyethylene, respectively. The contact was lubricated by pure saline and various protein solutions. The experiments were realized at two mean speeds equal to 5.7 mm/s and 22 mm/s and two slide-to-roll ratios, −150% and 150%. It was found that the implant material is the fundamental parameter affecting friction. In general, the metal pair exhibited approximately two times higher friction compared to the ceramic. In particular, the friction in the case of the metal varied between 0.3 and 0.6 while the ceramic pair exhibited friction within the range from 0.15 to 0.3 at the end of the test. The lowest friction was observed for polyethylene while it decreased to 0.05 under some conditions. It can be also concluded that adding proteins to the lubricant has a positive impact on friction in the case of hard-on-hard pairs. For hard-on-soft pairs, no substantial influence of proteins was observed. The effect of kinematic conditions was found to be negligible in most cases.

“…Subsequently, the contact was lubricated by the designed model SF. It is well known that the proteins significantly influence frictional behaviour of metal/ceramic-on-PE pair [30,31]. Composition of simulated SF was as follows: albumin = 20 mg/ml, γ-globulin = 3.6 mg/ml, hyaluronic acid (HA) = 2.5 mg/ml, phospholipids (PH) = 0.15 mg/ml; which fits to a physiological SF composition.…”

Running-in friction of hip joint replacements can be significantly reduced: The effect of surface-textured acetabular cup

et al. 2020

Hip joint replacements represent the most effective way of treatment for patients suffering from joint diseases. Despite the rapid improvement of implant materials over the last few decades, limited longevity associated with wear-related complications persists as the main drawback. Therefore, improved tribological performance is required in order to extend the service life of replacements. The effect of surface texturing of ultrahigh molecular weight polyethylene (UHMWPE) acetabular cup was investigated in the present study. Unique tilling method was utilized for manufacturing the dimples with controlled diameter and depths on the contact surface of the cup. The experiments with four commercial femoral components and two model lubricants were realized. The main attention was paid to a coefficient of friction considering the differences between the original and the dimpled cups. Results showed remarkable lowering of friction, in general. Focusing on the simulated human synovial fluid, friction was reduced by 40% (alumina ceramic), 38.8% (zirconia toughened ceramic), 25.5% (metal), and 9.9% (oxinium). In addition, the dimples helped to keep the friction stable without fluctuations. To conclude, the paper brings a new insight into frictional behaviour of the hip replacements during running-in phase which is essential for overall implant lifespan. It is believed that proper surface texturing may rapidly improve the life quality of millions of patients and may lead to considerable financial savings.

The tribological behavior between orthopedic implants and cortical bone is important but usually neglected. Poly(ether‐ether‐ketone) (PEEK) is a promising material for orthopedic applications. To further understand and improve the interfacial tribological properties between PEEK implant and host bone tissue, a PEEK‐cortical bone tribo‐pair is designed and fabricated. The frictional and wear performance of such tribo‐pair is investigated under different lubricants, i.e., simulated body fluid (SBF), calf serum (CS), hyaluronic acid (HA), and mucin (MUC). The results suggest that MUC solution can be utilized as an artificial natural synovial fluid to improve the tribological properties of PEEK‐based implants.
