Objective: This study aimed to investigate the relationship between kinesiophobia and pain catastrophizing with pain, range of motion, muscle strength, and function in patients with knee osteoarthritis. Methods: 18 female knee osteoarthritis patients between the ages of 50-70 who were found to have kinesiophobia and pain catastrophizing were included in the study. Kinesiophobia, pain catastrophizing, pain, range of motion, muscle strength, and functional status were evaluated within the scope of the study. Results: A statistically significant strong positive correlation between kinesiophobia and pain intensity during activity (r=0.80, p<0.001); a statistically significant moderate negative correlation between kinesiophobia and active knee flexion angle (r=-0.48, p<0.05); a statistically significant moderate positive correlation between kinesiophobia and the Five Times Sit to Stand Test time and the Stair Climb Test time (r=0.51, p<0.05; r=0.67, p<0.05, respectively) was found. A statistically significant moderate positive correlation between pain catastrophizing and resting pain intensity, pain intensity at night, pain intensity during activity, and passive knee extension angle (r=0.66, p<0.01; r=0.61, p<0.01; r=0.47, p<0.05; r=0.48, p<0.05, respectively); a statistically significant moderate negative correlation between pain catastrophizing and active knee flexion angle (r=-0.49, p<0.05) was found. Conclusions: It was determined that as kinesiophobia increased in patients with knee osteoarthritis, pain, range of motion, muscle strength, and functional status worsened, and the increase in pain catastrophizing was associated with worsening in pain and range of motion. Therefore, it was concluded that reducing kinesiophobia, and pain catastrophizing levels would contribute to improving functions in patients with knee osteoarthritis
