Overview
Some patients complain of articular noise (such as clicking, snapping, cracking or popping) after a total knee replacement. Controversy remains about whether there is a correlation between articular noise and worse outcomes following a knee replacement. A study by Nam et al. on 1540 patients revealed an association between noise and residual symptoms 30 days after they received a total knee replacement. Conversely, a study by Kuriyama et al. on 60 patients revealed no correlation between noise and patient satisfaction after 1 year of receiving a total knee replacement. The incidence of noise following a knee replacement has rarely been studied as a primary outcome. Like pain, it could be considered an important patient-reported outcome to assess patient satisfaction. The study aims to compare the prevalence of patient-perceived noise of an ultra-congruent total knee prosthesis (Score 2, Amplitude) versus a posterior-stabilized total knee prosthesis (Anatomic, Amplitude).
