Abstract :
Background: Noise levels in the operating theatre (OT) during Total Knee Replacement (TKR) surgeries can impact surgical precision, communication, and staff well-being. This study evaluates the effects of noise-reducing interventions on surgical outcomes and staff satisfaction in TKR procedures and trying to achieve as much Silent TKR as possible.Materials and Methods: A total of 104 TKR surgeries were performed, with 50 conducted using conventional OT practices and 54 using noise-reducing interventions during Jan 1st 2023 to Dec 31st 2024. The noise reducing interventions included minimal verbal exchanges, the use of noise-isolating ear pods, reduced but optimal staff presence, and minimized instrument handling. Verbal communication was observed using modified OTAS based checklist. Intraoperative noise levels were measured, and post-operative complications, surgical time, and staff-reported satisfaction were assessed.Results: The noise-reducing group demonstrated lower intraoperative noise levels (mean reduction of 27.5 dB%, p
