Postoperative education is crucial for improving physical function, daily activity participation, and quality of life after total hip arthroplasty (THA). The aim of our study was to examine the effects of patient education on function, quality of life, and activities of daily living after THA. Patients who underwent primary THA were randomized into three groups: online education, brochure, and control. Pain (VAS), function (WOMAC), quality of life (WHOQOL-BREF), and daily living activities (IADL) were evaluated online before education and four weeks after discharge.
