Body Mass Index and its Correlation with Knee Pain in Osteoarthritis Patients

ABSTRACT

Background: The goal of this study was to evaluate the correlation between body mass index (BMI) and severity of knee pain. Methods: Total 105 OA patients with knee pain selected on the basis of radiological diagnosis of OA knee were included. Evaluation of OA was done by using Kallgren and Lawrence grading along with numerical pain rating scale (NPRS). Results: Findings of the present study showed that number of OA patients 12 (11.4%), 40(38.09%), 30 (28.57%) and 33 (31.4%) were suffering with grade1 to 4 OA severities respectively. Further, Pearson correlation coefficient showed a positive correlation between BMI and NPRS (r=0.237, p>0.001). Conclusion: Findings of the current study show that BMI is significantly correlated with severity of pain of knee in OA patients as higher the BMI greater the pain of knee. Therefore, pain in knee patients with higher BMI should be advised to decrease weight via suitable exercise program.
