A review of squeaking in ceramic total hip prostheses
The occurrence of audible squeaking in some patients with ceramic-on-ceramic (CoC) hip prostheses is a cause for concern. Great effort has been dedicated to understand the mechanics of the hip squeaking to gain a deeper insight into factors contributing to sound emission from CoC hip articulation. Disruption of fluid-film lubrication and friction were reported as the main potential cause, while...
متن کاملA Computational Analysis of Squeaking Hip Prostheses
A ceramic-on-ceramic (CoC) hip prosthesis with clearance is modeled as a multibody dynamics system for the purpose of studying hip squeaking. A continuous contact force model provides the intrajoint forces developed at the hip joint. Friction effects due to the relative motion are also considered. A FFT analysis of the audible sounds from CoC hip acceleration is carried out to analyze hip squea...
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...
متن کاملInfluence of prosthetic design on squeaking after ceramic-on-ceramic total hip arthroplasty.
Squeaky ceramic-on-ceramic (COC) total hips have received much recent publicity, and implant design may be implicated. We reviewed 270 consecutive COC total hip arthroplasties in 233 patients comparing 4 implant combinations representing 4 manufacturers. A cohort (n = 45) of Stryker Trident acetabular cups paired with Stryker Accolade femoral stems showed a dramatically higher incidence of "pro...
متن کاملTotal Hip Arthroplasty Using Ceramic-on-ceramic Bearing Surfaces: Long-term Assessment of Squeaking Sounds
Purpose This study was performed to characterize the natural history of squeaking sounds that occur following total hip arthroplasty (THA) using ceramic-on-ceramic bearing surfaces and its potential correlation with clinical and/or radiological results. Materials and Methods This study included 47 patients who underwent THA between April 1999 and April 2005, and had at least 10 years of follo...
