Development and validation of an acoustic emission device to measure wear in total hip replacements in-vitro and in-vivo

摘要

An increasing demand for total joint replacement surgeries has provided a great need for more effective diagnostic procedures for monitoring and identifying wear, loosening, and other failure modes in total joint replacement implants. Significant recent research attention has been focussed on the contributing factors to wear and audible squeaking of total hip replacement (THR) implants and in particular those with hard-on-hard bearing combinations. An acoustic emission (AE) monitoring prototype diagnostic device has been developed for the assessment of implant wear and stability in THR patients.
