Based on the radiographic findings and clinical evaluation, the orthopaedic specialist will refer eligible patients to a physiotherapist, who will assign them to the TG or CG. The physiotherapist will provide both verbal and written explanations of the study procedures. Patients will be included in the study after providing written informed consent. Baseline Assessments The physiotherapist will collect baseline data, including: Sociodemographic characteristics, Anthropometric measurements: height (cm), weight (kg), body mass index (BMI) (kg/m²), Educational background and employment status, Knee joint mobility assessment using a goniometer, Pain intensity measurement using the Numerical Rating Scale (NRS), Physical function, stiffness, and pain assessment using the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), Physical activity evaluation using the International Physical Activity Questionnaire (IPAQ), Health-related quality of life assessment using the 12-Item Short Form Health Survey (SF-12), OA severity classification based on recent knee radiographs (≤ 4 months old), graded using the Kellgren-Lawrence classification system.
