Evaluating Public Perceptions and Attitudes Toward Total Knee Arthroplasty: A Cross- Sectional Study in Saudi Arabia

Background: Total knee arthroplasty is a surgical procedure used to address knee conditions, including osteoarthritis, that cause persistent pain and impaired joint function. While total knee arthroplasty is effective, misconceptions and knowledge gaps exist among the general public, particularly in Saudi Arabia.Methods: This cross-sectional study, conducted in Al-Ahsa, Saudi Arabia, utilized an online survey to assess public perception of total knee arthroplasty. A questionnaire was developed, validated, and administered to participants aged 18 and above with a history of chronic knee pain. Data were analyzed for associations between knowledge and perception scores and sociodemographic factors.Results: Out of 704 participants, the majority exhibited poor knowledge (74.1%) of total knee arthroplasty. Factors influencing knowledge included age, education, income, knowing someone who had total knee arthroplasty, hearing about total knee arthroplasty, receiving total knee arthroplasty information, and awareness of total knee arthroplasty indications. Sociodemographic characteristics such as gender, marital status, and perceptions about total knee arthroplasty prevalence did not significantly impact knowledge scores.Conclusion: This study reveals a significant knowledge and perception gap among the public in Al-Ahsa, Saudi Arabia, regarding total knee arthroplasty. Tailored education initiatives for patients with chronic knee pain are urgently needed to dispel misconceptions and provide accurate information about total knee arthroplasty. Collaborative efforts between policymakers, healthcare providers, and public health authorities are essential for improving public understanding, enhancing healthcare decision-making, and reducing the burden on healthcare systems.
