“…The first involves sound that is generated by extra-articular impingement of the femoral neck on the acetabular component. 59,60 A second process is said to be dependent on increased friction of the bearing couple, causing resonance and the production of audible noise 61 (Fig. 3).…”

Squeaking arising from a ceramic-on-ceramic (CoC) total hip replacement (THR) may cause patient concern and in some cases causes patients to seek revision surgery. We performed a meta-analysis to determine the incidence of squeaking and the incidence of revision surgery for squeaking. A total of 43 studies including 16,828 CoC THR that reported squeaking, or revision for squeaking, were entered into the analysis. The incidence of squeaking was 4.2% and the incidence of revision for squeaking was 0.2%. The incidence of squeaking in patients receiving the Accolade femoral stem was 8.3%, and the incidence of revision for squeaking in these patients was 1.3%.

“…Both femoral heads and acetabular cups fabricated from ceramic materials have been used, mainly due to the high hardness, chemical inertness, low coefficient of friction and tolerance by the organism 45 . It should be pointed out that, despite the expected superior wear performance, retrieved ceramic couples in some cases have shown a long, narrow area of damage, which has been called stripe wear 46 . Stripe wear is associated with edge loading, which is the contact between the head and the edge of the liner.…”

“…This contact results from misalignment between the center of femoral head and the center of the acetabular cup. It is related to the migration of the femoral component, producing distal translation and internal rotation, in such way that the final position of the component is retroverted 46 . Variation in translational positioning of the centers of the head and cup, which is not detected on radiographs, is a frequent clinically occurrence and can result in substantial increase in wear rate 35 .…”

Total hip arthroplasty (THA) is a surgical procedure that involves the replacement of the damaged joint of the hip by an artificial device. Despite the recognized clinical success of hip implants, wear of the articulating surfaces remains as one of the critical issues influencing performance. Common material combinations used in hip designs comprise metal-on-polymer (MoP), ceramic-on-polymer (CoP), metal-on-metal (MoM), and ceramic-on-ceramic (CoC). However, when the design of the hip implant is concerned besides the materials used, several parameters can influence its wear performance. In this scenario, where the safety and efficacy for the patient are the main issues, it is fundamental to evaluate and predict the wear rate of the hip implant design before its use in THA. This is one of the issues that should be taken into account in the preclinical evaluation step of the product, in which simulated laboratory tests are necessary. However, it is fundamental that the applied motions and loads can reproduce the wear mechanisms physiologically observed in the patient. To replicate the in vivo angular displacements and loadings, special machines known as joint simulators are employed. This article focuses on the main characteristics related to the wear simulation of hip implants using mechanical simulators, giving information to surgeons, researchers, regulatory bodies, etc., about the importance of preclinical wear evaluation. A critical analysis is performed on the differences in the principles of operation of simulators and their effects on the final results, and about future trends in wear simulation.

“…No patients in our series reported any squeaking. Squeaking can be caused by extra-articular impingement of the femoral neck on the acetabular component or by increased friction of the bearing couple (41). A meta-analysis of 43 studies including 16,828 CoC hip replacements reported the incidence of squeaking to be 4.2% (42).…”
