Introduction: The success of ceramic implants is attributed to the excellent properties of this material associated
with superior wear rates and a chemically inert nature which grants it biocompatibility and greater longevity compared
with the traditional metal-on-polyethylene bearing surface. However, there have been an increasing number of reports
on audible noises that seemed linked to these hard bearing surfaces, leading some to believe the implant material or
design was still to blame.
Case report: In this paper is presented the case of an unusual noise which occurred in a 73 year old woman 6
years after THA implant.
Discussion: We hypothesized that the possible cause of this “click” was the impingement of the neck of the
stem against the acetabulum ream or as an other possibility some sort of movement between the metal back and the
acetabular ceramic liner. During the revision surgery the first hypothesis have been confirmed. Thus, we believed that
correcting the position of the cup could reduce the possibility of the clicking caused from the impingement.
Conclusion: Noise in ceramic-on-ceramic THRs is not a single factor related event but rather it is a multifactorial
phenomenon. Although several theories have been suggested, the mechanisms responsible has not yet clearly
