Fretting corrosion at the head–neck interface of modular hip implants, entailsscientifically termed trunnionosis/taperosis, may cause regional inflammation a, metallosis, and adverse local tissue reactions. Surface topography is one key factor which can The severity of such a deleterious process depends on various design parameters. In this review, the influence the severity of this damage mechanismof 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 main simplifications, as well as the findings from both the experimental and nobservations (retrieval and in vitro) and the numerical sapproaches used in previous studies, are presented to evaluate tand discussed. The performance of the microgrooved junctions using two criteria as is compared to those with a smooth surface finish in two main categories: stability and integrity; wear, corrosion, and material loss. CExisting 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 foron the microgrooved junctions are thenalso identified and presented.
