“…In conclusion, the present results represent additional evidence on short-term MPC-grafted retrieved liners, which sums up to those of our previous study of three short-term retrievals (Jay & Waller, 2014) and to a number of additional short-term retrievals presented by other researchers (Stewart, 2010;Zhu et al, 2017).…”

MPC‐grafted highly cross‐linked polyethylene liners retrieved from short‐term total hip arthroplasty: Further evidences for the unsuitability of the MPC method

An analysis is presented of four short‐term retrieved highly crosslinked polyethylene (HXLPE) hip liners grafted with 2‐methacryloyloxyethyl phosphorylcholine (MPC) on their bearing surfaces, which were recently commercialized as a new generation of artificial hip joints. Straightforward evidences by X‐ray photoelectron spectroscopy (XPS) confirmed that the MPC layer peeled off on the bearing surface of all short‐term liners in both main wear and nonwear zones. Analyses by Fourier‐transform infrared spectroscopy with attenuated total reflection assessed the extent of surface oxidation and revealed the type of oxidative species. Electron spin resonance analyses, which compared retrievals and as‐received samples, revealed the presence of different species of alkoxyl CO• radicals. This study suggests that MPC grafts on polyethylene do not offer any additional protection from oxidation and can delaminate prematurely after short‐term in vivo exposure.

“…Wear occurs during interaction of surfaces under relative motion and includes abrasion where a harder surface wears against a softer surface, adhesion from shear stresses, and fatigue from exceeding the material’s fatigue strength. Corrosion occurs when metal comes into contact with air and undergoes oxidation [1] . Wimmer et al.…”

“…[22] demonstrated that corrosion can be beneficial, as oxidation of the metal components before implantation forms a protective tribochemical film that reduces wear through lubrication. However, the same oxide film's relative softness results in fretting wear and repeat oxidation, causing generation and delamination of the film, and potentiating a vicious cycle of protection and wear, causing deposition of local metal debris of varying microscopic and macroscopic sizes [1] , [22] .…”

“…Metallosis is a well-described complication of metal-on-metal (MoM) hip resurfacing and can precipitate systemic toxicity. Metallosis results from wear and corrosion of metal-containing implants causing deposition of metal particles into the local tissue; this can be seen at any bearing joint including the head-acetabulum junction and trunnion [1] , [2] . Prior reports have articulated a distinction between local and systemic deposition of metal debris.…”

Systemic cobaltism manifesting as oral mucosal discoloration and metallic gustation after metal-on-metal hip resurfacing

Systemic cobaltism is a debilitating complication of metal-on-metal (MoM) arthroplasty. In this report, we review a case of a 54-year-old female with metallosis from a MoM hip resurfacing and varying degrees of black discoloration of her tongue and metallic gustation as a result of systemic cobaltism. After explanting the metal components, thorough debridement, and conversion to ceramic-on-polyethylene arthroplasty, the patient’s oral mucosal discoloration and metallic gustation resolved. This represents the first documentation of systemic cobaltism from MoM hip resurfacing manifesting as oral mucosal discoloration and metallic gustation with resolution after explant, debridement, and conversion to ceramic-on-polyethylene total hip arthroplasty.

“…Investigations into lubricin are also being made by Alexandra et al [23] to synthesize and characterize a libricin mimic which will be able to behave similar to lubricin in synovial fluids and be able to reduce friction and adhesion on articular cartilage surface. Recently, many such research concerning role of lubricin and boundary layer lubrication have been analyzed with respect to the lubrication and wear mechanisms observed in synovial joints and articular joints in general [24][25][26][27][28][29][30][31]. These researches are aimed to help better understand the technology behind one of nature's most effective lubrication mechanism.…”

Bio-inspired tribology is an interdisciplinary field of science where scientists and engineers seek to investigate and incorporate tribological properties encountered in biological beings into engineering applications. In this paper, bio-inspired tribological research that are speculated to have a huge impact on tribological applications have been reviewed. These research involve (1) investigations related to replication of lubricin found in synovial fluids of mammalian joints which have super-low friction values that can be utilized in IC engines, (2) surface replication concerning to superhydrophobic properties of gecko skin which is seen to have anti-wetting and selfcleaning properties, (3) friction-reducing shark skin through specialized nanoparticle coatings that is seen to give a different perspective on surface texturing, (4) new techniques, such as soft lithography to replicate surfaces of lotus leaf and air lubrication phenomenon inspired by emperor penguins that is being applied to propel boats, ships, and torpedoes faster by reducing skin friction underwater. Further, an investigation in self-healing materials inspired from pitcher plant that has led to the innovation of self-healing and slippery liquid-infused porous surfaces has been discussed. These research works reviewed not only provide a deep insight into the current advances in bio-inspired tribology but also helps understand the plausibility of the research applications in the future and the practicality of innovations possible.
