Materials and Method: We included 145 patients (age, 55.9±8 years) diagnosed with osteoarthritis of the knee in this study. Kinesiophobia, pain intensity, quadriceps muscle strength, disability and quality of life were evaluated using Tampa Scale for Kinesiophobia, visual analogue scale, hand-held dynamometer, Lysholm scale and short form-36, respectively.
Results: There was a significant relationship between pain at rest (p= .028), pain during activity (p=.015), disability (p=.019), vitality (p=.03) and social function (p=.036) of short form-36 and quadriceps muscle strength in females. No significant relationship was found between the test variables and quadriceps muscle strength (p> .05) in males. There was a significant relationship between pain during activity (p=.021), quadriceps muscle strength (p=.017), vitality (p=.026) and social function (p=.007) parameters of quality of life and kinesiophobia in females. There was a significant association between quadriceps muscle strength and kinesiophobia (p=.001) in males.
Conclusion: Quadriceps muscle weakness was associated with increased pain intensity and disability and reduced quality of life in females but not in males with osteoarthritis. Additionally, kinesiophobia was associated with higher pain intensity during activity, quadriceps muscle weakness and poorer quality of life in females. In males, level of kinesiophobia was associated with quadriceps muscle weakness.
