Evaluation of Risk Factors for Knee Osteoarthritis in Patients with Knee Pain Complaints

Background & objectives: Knee osteoarthritis is an important cause of pain and disability in the community. The present study investigated the risk factors for primary osteoarthritis of the knee in patients with knee pain and their relationship with knee osteoarthritis. Methods: 87 patients were included in the study and were matched in terms of age. Cases consisted of female patients less than 50 years of age with knee pain and the control group was selected from patients under 50 years of age with knee pain and no radiographic findings of osteoarthritis. Results: This study showed that the rate of osteoarthritis of the knee was significantly related to body mass index ( p =0.001). The relationship between knee osteoarthritis and ESR was not significant, but an increase in CRP with a p -value of 0.01 was associated with a risk of approximately a 3.5-fold increase in knee osteoarthritis. With increasing education, the rate of knee osteoarthritis decreased ( p =0.022). The Increased circadian outpatient activity was significantly associated with increased knee osteoarthritis ( p =0.032). In performed assessments on osteoarthritis of the knee, there was no statistically significant relationship between the type of bathroom used, the use of stairs, and residential houses. Conclusion: Knee osteoarthritis has a relationship with body mass index, Education level, CRP index, and circadian activity level. it is recommended to lose weight in people with abnormal body mass index, exercise, and improve their lifestyle to reduce the incidence of knee osteoarthritis and disability.
