Abstract

Objectives: Elderly people with knee OSTEOARTHRITIS are more likely to become disabled than others. We aimed to explore the association between two treatments and pain severity in women aged 50-75 years who suffered from knee OSTEOARTHRITIS.Methods & Materials: 40 women with knee OSTEOARTHRITIS were randomized into two groups: to either received common treatment or common treatment accompanied by knee traction. The binary response variable was pain severity. Participants were followed up for 10 times. Because of missing data, the multiple-imputation-based GENERALIZED ESTIMATING EQUATIONS (MI-GEE) method was used to estimate the odds of a pain as a function of the treatment groups adjusted for age and body mass index. Data were analyzed by R software. Adjusted ODDS RATIOs and 95% confidence intervals were estimated.Results: In multivariate model, we found an association between pain severity and treatment (P=0.004). The pain ODDS RATIOs was 0.28 (95% CI: 0.12-0.65) for common treatment accompanied by knee traction group.Conclusion: The pain was found to be lower among patients treated with common treatment accompanied by knee traction than patients treated with only common treatment.
