BackgroundGonarthrosis is a chronic degenerative joint disease characterised by prolonged pain, affecting ~10% of men and 18% of women aged 60 and older worldwide. Surgical interventions are commonly employed in patients with gonarthrosis to minimise disability, alleviate pain, and improve overall quality of life. However, surgical treatment remains a feared experience. This study was conducted to identify the levels of spiritual well‐being and surgical anxiety in elderly patients diagnosed with gonarthrosis who are scheduled for surgical intervention. The aim was to examine the relationship between these factors and identify influencing elements.MethodsThis descriptive and correlational study was conducted between September 2022 and June 2023 in the orthopaedics and traumatology service of a state hospital, involving 105 patients aged 65 and above with gonarthrosis and admitted for treatment. Data were collected using the Personal Information Form, Surgical Fear Questionnaire, and Three‐Factor Spiritual Well‐being Scale. Data were analyzed with descriptive statistical tests, Mann–Whitney U‐test, Kruskal–Wallis test, and Spearman correlation analysis.ResultsThe short‐term surgical fear of patients was 11.69 ± 7.55, the long‐term surgical fear was 10.70 ± 9.53, and the total surgical fear was 22.40 ± 14.69 points, indicating a low level. Single and inexperienced elderly patients had higher levels of surgical fear (P < 0.05). The spiritual well‐being levels of elderly patients (transcendence, 59.65 ± 12.20; harmony with nature, 29.10 ± 4.65; anomy, 26.34 ± 5.28; total score, 115.10 ± 17.83) were high. The spiritual well‐being levels of elderly individuals whose income matched their expenses were higher (P < 0.05). There was a statistically significant negative relationship between the level of anomy in elderly patients with gonarthrosis and surgical fear (P < 0.05).ConclusionsIn elderly patients with planned surgical interventions for gonarthrosis. It was determined that the levels of surgical fear were low, and the levels of spiritual well‐being were high. The study identified that the level of anomy had an impact on surgical fear. It is recommended that healthcare professionals be aware of the influence of spiritual well‐being on surgical fear and provide spiritual support to elderly patients.
