Abstract

Ceramic-on-ceramic bearings for total hip arthroplasty (THA) are considered to be the best choice to avoid problems such as osteolysis and wear, which are mainly caused by soft bearings. Recent concerns have been raised because of some clinical reports on the presence of audible noise (squeaking) in some ceramic-on-ceramic total hip replacements. The occurrence of squeaking in some patients is related to a complex of tribological and dynamical interactions in the prosthesis components. Such mechanisms include edge loading, stripe wear, impingement, synovial lubrication film ruptures, third body particles, ceramic fracture, and vibrational modes of the entire structure. The resonance of metallic parts can produce noise in the human audible frequencies range, hence the implant metallurgic composition, the design and the tribological behavior play a key role. The aim of this scoping review is to map and summarize the available scientific evidence on hip squeaking, highlighting the theoretical fundamentals on the genesis of the phenomenon with its causes and effects, the adopted numerical approaches together with in-situ experiments, results about squeaking analysis of total hip replacements listed in order of time so that it is easier follow the progress of science and the research future directions. Hence the scope is to provide a comprehensive but at the same time exhaustive document that could help researchers, students, etc. to study more deeply this field.
