comparison of music and ambient noise cancellation in patients undergoing total knee arthroplasty (tka)

Conditions: Knee Osteoarthritis; Anxiety; Post Operative Pain; Noise Exposure

Summary: 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.

osteoarthritis is a degenerative and progressive knee disease that causes progressive loss of articular cartilage. according to the study by harvey et al., osteoarthritis, the most common form of arthritis, is the most common cause of joint function limitation among the elderly. osteoarthritis is common in load-bearing joints and one of these joints is the knee joint. according to a study by dawson et al, the rate of symptomatic knee and hip osteoarthritis in individuals over 65 years of age was reported to be 40%. in patients with gonarthrosis (knee osteoarthritis), lifestyle changes, drug therapy and rehabilitation are recommended in the early stages (stages 1-2), while total knee arthroplasty comes to the fore in the later stages (stages 3-4). orthopaedic surgery operating rooms are generally known as noisy working environments. especially joint surgeries such as total knee arthroplasty and total hip arthroplasty have a close relationship with noise due to the cutting motors, hammers and osteophyte excision procedures used during surgery. this noise during surgery may be associated with anxiety and delayed onset of movement in the postoperative period. it is thought that the sympathetic nervous system, which is activated as a result of anxiety, may cause delayed wound healing and delay in the return of functional activity with the release of stress hormones. the use of music as a medical treatment has gained importance in recent years. according to the study of wu et al. it was observed that music in the environment during awake craniotomy decreased anxiety, pulse rate and blood pressure.
