The aim of this clinical trial is to compare the effects of music and ambient noise cancellation during total knee arthroplasty and to analyse the effects on patients. The study will also collect information on patients' functional knee scores and anxiety levels. The main questions to be answered are the following: Does the blocking of music or ambient noise, which is predicted to reduce anxiety, reduce people's anxiety levels? To what extent are participants affected by ambient noise? Does music or ambient noise blocking lead to an improvement in patients' functional scores? The researchers will work with 3 groups of patients who will be exposed to ambient noise blocking, music playing and ambient noise during knee replacement surgery. Participants will do the following: Be asked questions about anxiety and knee function scores before and after surgery. Attend clinical examinations at specified times for checks and tests. Outcomes will be assessed and recorded at appropriate times.
