Non-invasive vibrometry-based diagnostic detection of acetabular cup loosening in total hip replacement (THR)

Total hip replacement (THR) is aimed at relieving pain and restoring function. The procedure has come a long way since it was introduced by Charnley in the early 1960  s, and was nominated as the operation of the century [1]. The high success rate of THR has contributed to the rapid increase in its use, with well over one million operations performed annually worldwide [2]. However, approximately about 4%–10% of all the involved implants are expected to fail in their first decade [3,4], mostly due to aseptic loosening, which has been identified as the primary THR failure factor since 1979 [5].
