Patients with moderate to severe OA have persistent pain that significantly affects their functional status, activity participation, and quality of life. As with mild OA, non-pharmacological interventions that focus on education, exercise, and weight management are first-line treatments for patients with moderate to severe knee OA.~Exercise is recommended for all patients with moderate to severe knee OA to reduce pain and protect the joint. A meta-analysis showed that exercise has beneficial effects on pain, even in patients with severe disease and awaiting total knee replacement.~The aim of this study was to compare the effects of anti-gravity treadmill training and traditional treadmill training treatments combined with strengthening exercises on patients' pain levels, quality of life, distal femoral cartilage thickness, and functional capacity in patients with moderate and severe knee OA. In addition, it was aimed to compare the compliance of the patients to aerobic exercise.
