Objectives: Many patients with knee osteoarthritis refuse to undergo total knee replacement (TKR) and would rather tolerate the symptoms. This study aimed to collect information that described patients' perceptions of TKR and to identify factors that influenced decision-making about TKR and other available treatment options. Methods: This descriptive cross-sectional study was conducted in a hospital's orthopedic outpatient clinic. The study began in 2018 and used a self-administered questionnaire that comprised 16 questions and four domains, namely, activity expectations, current difficulties, expected complications, and general health. The questionnaire was completed by patients who had been advised to undergo TKR, who were aged ≥30 years, and who could read and understand Arabic. Patients with histories of orthopedic surgery were excluded. Results: A total of 362 patients participated in the study. The level of education was significantly associated with activity expectations (P < 0.025) and current difficulties (P < 0.012) negatively. The body mass index (BMI) was significantly associated with current difficulties (P < 0.002) and general health (P < 0.001). Age, gender, and marital status were not associated with the questionnaire's domains. Conclusion: The BMI and the level of education affected patients' perceptions of TKR. Low levels of expectation in relation to surgery impact upon patients' decision-making processes and could affect their quality of life.
