Objectives To examine associations of knee symptoms with self-reported physical function of individuals with knee osteoarthritis (OA).
Methods We examined differences in pain, pain sensitivity, function, psychosocial variables, and physical activity between women and men with knee osteoarthritis. The knee symptoms was defined as pain, aching, or stiffness at least 3 months before inclusion into study. Physical function was assessed by the RAPID 3 (Routine Assessment of Patient Index Data) is a index of only the three Core Data Set patient self-report measures—physical function (from 0- to 3) converted to 0-10, pain 0-10, and patient global estimate (0- 10) for a total of 0-30 points. Separate multivariable logistic regression models examined associations between knee symptoms and physical function measures, by age, sex and geografic locality. The study was approved by local institutional review board, and all subjects gave written informed consent.
Results In study cohort were included 123 patients with OA aged 40 years or older. Patients completed the RAPID 3 questionaire and visual analog scale for pain (VAS). Patient characteristics: the mean age was 64.3 years, 69,2% was female. For the entire sample, pain was present in 90.6% of patients. Women had significantly worse pain than men, VAS pain was 61.3 mm and men 58,6 mm, respectivily (p>0.05). The level of physical function did not differ significantly between women 3.7 and men - 4.1 points (p<0.05). The total RAPID 3 score was for men 19.1, and for women -16.0 points (p<0.05).
Conclusions Pain is very common in this sample of patients with knee osteoarthritis. Women continue to be as physically active as men even though higher levels of pain. The knee osteoarthritis estimate negatively affect the patient’s condition scoring RAPID 3 generally men worse than women.
