title: Noise production in ceramic-on-ceramic total hip arthroplasty is associated with lower patient satisfaction and hip scores.
abstract: Ceramic-on-ceramic total hip arthroplasties (THA) are commonly implanted. We investigated the incidence of noise in ceramic-on-ceramic and determined any association with patient satisfaction and hip scores.
  We recruited 140 THA. Questionnaires were completed to assess the incidence and frequency of noise, and satisfaction level. Hip and SF-12 scores were recorded.
  Forty-two patients (30%) were aware of noise production. Patients with noise production had lower satisfaction, mean hip and SF-12 scores than those with silent hips.
  Given the high incidence of noise in ceramic-on-ceramic THA, patients should be counselled on this risk pre-operatively.
