Background: Discordance between knee pain and radiologic osteoarthritis is well?known. This study was to investigate
factors associated with knee pain with different grades of knee osteoarthritis among Korean adults
aged 50 years or more.
Methods: Total 5,978 Korean aged 50 years or more who underwent the radiographs of the knees were analyzed
from Korean National Nutrition and Health Examination Survey conducted in 2010?11. Radiographs of the
knees were scored for osteoarthritis using the Kellgren?Lawrence scale. Multivariate logistic regression analysis
adjusting for sociodemographic factors, lifestyle factors, comorbidity and health status was used for
analysis.
Results: The prevalence of knee pain was higher in female compared to that of male (P<0.001), and increased
as increasing severity of radiologic knee osteoarthritis. Female was associated with increased risk of knee pain
in all of Kellgren?Lawrence degrees. In most of Kellgren?Lawrence degrees, depression was associated with increased
risk of knee pain, and those with high school diploma or higher were associated with decreased risk of
knee pain. A few factors (age, body mass index, and no alcohol drinking) were also associated with increased
risk of knee pain for particular grades of radiographic knee osteoarthritis.
Conclusions: Knee pain increased as increasing severity of radiologic knee osteoarthritis. Although there were
differences of risk factors associated with knee pain with different grades of knee osteoarthritis, female, depression
were associated with increased of knee pain, and those with high school diploma or higher were associated
with decreased risk of knee pain in most of Kellgren?Lawrence degrees.
