This study aims to the functional outcomes of primary total knee arthroplasty (TKA) in Abha city and also to identify the effect of obesity on the development of primary TKA.
Methods: A retrospective cohort was conducted targeting all patients who underwent TKA in Abha city from July 2018 to November 2021 from the orthopedic department at Aseer Central Hospital and Khamis General Hospital. The questionnaire employed besides the demographic data covered TKA-relevant data, including side, post-surgical complications, and adherence to post-surgical physiotherapy. Knee arthroplasty was assessed based on the Oxford Knee Scale and a pre-existing medical record.
