“…5 ). However, measurement of retrieved ceramic implants revealed much higher wear rates than above (≥ 1 mm 3 / yr.) and a characteristic "ceramic" wear pattern was noted [6][7][8] . The reason for these differences could lie in different biomechanical conditions in vitro and in vivo, with the latter being exposed to edge loading, recurrent separation of bearing surfaces and even direct impingement of the ceramic implant on the neck of the stem, that increase the total wear of the implant in vivo.…”

Background. Ceramic on ceramic (COC) total hip arthroplasty (THA) was developed to reduce wear debris and accordingly, the occurrence of osteolysis and aseptic loosening especially in younger patients. Based on the excellent tribological behavior of current COC bearings and the relatively low biological activity of ceramic particles, significant improvement in survivorship of these implants is expected. Methods. We used manual search to identify all relevant studies reporting clinical data on COC THAs in PubMed. The objective was to determine whether current COC THA offers a better clinical outcome and survivorship than non-COC THA. Results. Studies with early generation ceramic bearings yielded 68% to 84% mean survivorship at 20 years follow-up which is comparable with the survivorship of non-COC THAs. Studies on current ceramic bearings report a 10-year revision-free interval of 92% to 99%. These outcomes are comparable to the survivorship of the best non-COC THAs. However, there are still concerns regarding fracture of sandwich ceramic liners, squeaking, and impingement of the femoral neck on the rim of the ceramic liner leading to chipping, especially in younger and physically active patients. Conclusion. Current COC THA leads to equivalent but not improved survivorship at 10 years follow-up in comparison to the best non-COC THA. Based on this review, we recommend that surgeons weigh the potential advantages and disadvantages of current COC THA in comparison to other bearing surfaces when considering young very active patients who are candidates for THA.

“…Similarly, for ceramic-on-ceramic (COC) THA articulations, in some studies, edge wear has been associated with squeaking [9,11,23,29] and/or stripe wear [26,30] of either the femoral head or the acetabular component or both, and in some situations, it can be associated with accelerated wear of the whole joint [17]. In view of the evidence showing edge Massachusetts General Hospital has received, in any 1 year, funding from Biomet, Inc (Warsaw, IN, USA), Zimmer, Inc (Warsaw, IN, USA), and DePuy Orthopaedics, Inc (Warsaw, IN, USA).…”

Edge Loading Has a Paradoxical Effect on Wear in Metal-on-Polyethylene Total Hip Arthroplasties

Background Edge wear is an adverse factor that can negatively impact certain THAs. In some metal-on-metal THAs, it can lead to adverse tissue reactions including aseptic lymphocytic vasculitis-associated lesions and even to pseudotumor formation. In some ceramic-on-ceramic THAs, it can lead to squeaking and/or stripe wear. Edge wear in metal-on-metal and ceramic-on-ceramic THAs can also be associated with accelerated wear across the articulation of these joints. Questions/purposes I asked: Does edge wear occur in metal-on-polyethylene (MOP) articulations? And if so, does it increase joint wear? Methods I examined the evidence in the literature for edge wear occurring in MOP THA and then assessed the evidence in the literature for data supporting the concept that edge wear in MOP hips could accelerate wear across the articulation over time.

“…At present, all patients undergoing total hip replacement should be counseled about the risk of squeaking, but ceramic-on-ceramic bearing surfaces in particular remain an attractive option because of the extremely low wear rates and low prevalence of osteolysis [47].…”

This review aims to update the reader with current thinking and research related to the well documented phenomenon of squeaking hip arthroplasties. The etiology of squeaking is multifactorial and still not well understood. We aim to share our own experience and views on the combination of factors we believe increases the likelihood of squeaking, along with mechanisms by which the sound may be generated. Recent published findings from other groups are summarized along with an appropriate management algorithm we recommend for this cohort of patients.
