Development of an acoustic measurement protocol to monitor acetabular implant fixation in cementless total hip Arthroplasty: A preliminary study

A large number of total hip arthroplasties (THA) are performed each year, during which the hip joint is replaced by an artificial joint. Over the past 30 years the number of THA increased by almost 200% in Sweden [1]. 12% –13% of all performed THA is revision surgery, for which aseptic loosening is reported to be the most common diagnosis [1]. Besides the design, material composition and surface characteristics, obtaining a proper intra-operative initial stability is one of the crucial factors necessary for a long term secondary stability [2].
