Background: American rheumatism association has defined OA as a heterogeneous group of condition that leads to joint symptoms & sign which are associated with defective integrity of articular cartilage, in addition to related changes in underlying bones & at the joint margins. It is mainly found in weight bearing joints. A high Q-angle interferes with the smooth gliding movement between the patella & the knee & over time eventually knee become degenerative & develop OA. Increased knee joint loads are present in patients with knee OA & interaction between axial alignment & dynamic knee joint loading is especially pronounced in patients with high BMI. The WHR suggests that truncal obesity is the greatest contributor to the relation between body habitus & chronic disease. So aim of this study was to find the correlation between BMI, WHR & Q-ANGLE in subjects with primary OA knee.
Methods: Total 185 subjects with age more than 38 years (male & female) were assessed of which out them 150 subjects were included in this study as per inclusion & exclusion criteria after detail assessment. Informed consent was taken in their preferred language.
Results: Mean & standard deviation of BMI , WHR & Q-ANGLE were 27.28 ± 4.05 kg/m2 , 0.91 ± 0.07 , 19.7° ± 2.06° respectively. Among these three variables, there was significant positive correlation between BMI & Q-ANGLE (p≤ 0.05) only where as insignificant positive correlation between BMI & WHR, insignificant negative correlation between WHR & Q-ANGLE was (p≥0.05) found.
Conclusion: These 3 independent parameters as risk factors for primary OA were also a risk factors for the same interdependently.

Key words: Primary OA, BMI, WHR, Q-ANGLE
