Retrieval analysis of squeaking alumina ceramic-on-ceramic bearings.
This multicentre study analysed 12 alumina ceramic-on-ceramic components retrieved from squeaking total hip replacements after a mean of 23 months in situ (11 to 61). The rates and patterns of wear seen in these squeaking hips were compared with those seen in matched controls using retrieval data from 33 'silent' hip replacements with similar ceramic bearings. All 12 bearings showed evidence ch...
متن کاملThe role of patient factors and implant position in squeaking of ceramic-on-ceramic total hip replacements.
We investigated factors that were thought to be associated with an increased incidence of squeaking of ceramic-on-ceramic total hip replacements. Between June 1997 and December 2008 the three senior authors implanted 2406 primary total hip replacements with a ceramic-on-ceramic bearing surface. The mean follow-up was 10.6 years. The diagnosis was primary osteoarthritis in each case, and no pati...
متن کاملFunctional orientation of the acetabular component in ceramic-on-ceramic total hip arthroplasty and its relevance to squeaking.
AIMS Long-term clinical outcomes for ceramic-on-ceramic (CoC) bearings are encouraging. However, there is a risk of squeaking. Guidelines for the orientation of the acetabular component are defined from static imaging, but the position of the pelvis and thus the acetabular component during activities associated with edge-loading are likely to be very different from those measured when the patie...
متن کاملCeramic liner fractures presenting as squeaking after primary total hip arthroplasty.
BACKGROUND Squeaking after ceramic-on-ceramic total hip arthroplasty is a relatively uncommon phenomenon. It usually does not require treatment in the absence of pain, mechanical symptoms, and/or relentless squeaking. The purpose of this investigation was to report on four patients who presented with hip pain and squeaking due to fractured ceramic liners after ceramic-on-ceramic total hip arthr...
متن کاملIn Vitro and in Vivo Analysis of Squeaking Frequencies in Ceramic-on-ceramic Total Hip Prosthesis
INTRODUCTION: Squeaking after total hip replacement has been reported in up to 10% of patients (1). Some authors proposed that sound emissions from squeaking hips result from resonance of one or other or both of the metal parts and not the bearing surfaces (2). There is no reported in vitro study about the squeaking frequencies under lubricated regime. The goal of the study was to reproduce the...
