Purpose The purpose of this paper is to study the roughness effect on the fixation of taper junction components and surfaces wear in terms of taper surface design. The roughness of the femoral heads’ taper and of the femoral stems’ trunnions can influence the fretting wear of the taper junction. Design/methodology/approach It was analysed whether a microgrooved taper surface of the femoral stem trunnion improves the fixation and reduces the wear rate at the taper junction of the hip prosthesis. Two models have studied: a femoral head with a smooth tapered surface combined with a microgrooved stem trunnion and a femoral head with a smooth tapered surface combined with a trunnion that had a smooth surface of the tapered. To compare the wear evolution between these two models, a computerised finite element model of the wear was used. Findings The results obtained after analysis carried out during millions of loading cycles showed that the depth of the linear wear and the total material loss were higher for the femoral heads joined with microgrooved trunnions. The main conclusion of this paper is that the smooth surfaces of the taper and of the trunnions will ensure a better fixation at the taper junction, and therefore, will reduce the volumetric wear rates. Originality/value A higher fixation of the taper junction will reduce the total hip prosthesis failure and, finally, it will improve the quality and durability of modular hip prostheses.

Pre‐clinical evaluation of fretting‐corrosion at stem‐head and stem‐cement interfaces of hip implants using in vitro and in silico models

Prior to clinical use, the corrosion resistance of new prosthesis system must be verified. The fretting‐corrosion mechanisms of total hip arthroplasty (THA) implants generate metal debris and ions that can increase the incidence of adverse tissue reactions. For cemented stems, there are at least two interfaces that can be damaged by fretting‐corrosion: stem‐head and stem‐cement. This investigation aimed to evaluate, through in vitro and in silico analyses, fretting‐corrosion at the stem‐head and stem‐cement interfaces, to determine which surface is most affected in pre‐clinical testing and identify the causes associated with the observed behavior. Unimodular stems and femoral heads of three different groups were evaluated, defined according to the head/stem material as group I (SS/SS), group II (CoCr/SS), and group III (CoCr/CoCr). Seven pairs of stems and heads per group were tested: three pairs were subjected to material characterization, three pairs to in vitro fretting‐corrosion testing, and one pair to geometric modeling in the in silico analysis. The absolute area of the stem body degraded was more than three times higher compared with the trunnion, for all groups. These results were corroborated by the in silico analysis results, which revealed that the average micromotion at the stem‐cement interface (9.65–15.66 μm) was higher than that at the stem‐head interface (0.55–1.08 μm). In conclusion, the degradation of the stem‐cement interface is predominant in the pre‐clinical set, indicating the need to consider the fretting‐corrosion at the stem‐cement interface during pre‐clinical implant evaluations.

“…These may subsequently reduce the probability of fluid ingress into the crevice-like gap of the junction due to the toggling effects, thus reducing the susceptibility to corrosion. The presence of such microgrooves is believed to partly compensate for the influence of unavoidable taper angle mismatch which results in a smaller contact area and possible drop in integrity [ 26 , 27 , 28 ]. Although modern junctions are mostly designed and manufactured with microgrooves, research confirms that there is a limited understanding of how these microgrooves affect the junction performance, as evident in the inconsistent and often contradictory results reported by researchers.…”

“…Although modern junctions are mostly designed and manufactured with microgrooves, research confirms that there is a limited understanding of how these microgrooves affect the junction performance, as evident in the inconsistent and often contradictory results reported by researchers. Some research studies confirm no significant role played by these microgrooves in the interface damage [ 29 , 30 ] but some others report higher/lower interfacial damage for these junctions [ 26 , 27 , 28 ]. There is also disagreement on the influence of these microgrooves on the pull/twist-off strength [ 24 , 28 ].…”

An Overview of the Stability and Fretting Corrosion of Microgrooved Necks in the Taper Junction of Hip Implants

Fretting corrosion at the head–neck interface of modular hip implants, scientifically termed trunnionosis/taperosis, may cause regional inflammation, metallosis, and adverse local tissue reactions. The severity of such a deleterious process depends on various design parameters. In this review, the influence of surface topography (in some cases, called microgrooves/ridges) on the overall performance of the microgrooved head–neck junctions is investigated. The methodologies together with the assumptions and simplifications, as well as the findings from both the experimental observations (retrieval and in vitro) and the numerical approaches used in previous studies, are presented and discussed. The performance of the microgrooved junctions is compared to those with a smooth surface finish in two main categories: stability and integrity; wear, corrosion, and material loss. Existing contradictions and disagreements among the reported results are reported and discussed in order to present a comprehensive picture of the microgrooved junctions. The current research needs and possible future research directions on the microgrooved junctions are also identified and presented.
