Background: The quadriceps angle (Q angle) is actually the alignment of the quadriceps femoris muscle. A perpendicular line from anterior superior iliac spine to centre of the patella, another line from centre of patella to tibial tuberosity and the point of intersection of these lines forms an angle known as Q angle. Aim and objective; Determining the value, bilateral variability and relationship of Quadriceps angle with Height Weight and BMI in supine position in female population of hilly and plain region of Uttarakhand. Methods: 370 healthy females 200 from hilly region and 170 from plain region of age group 18-65 were included in the study. A perpendicular line was drawn from anterior superior iliac spine to centre of the patella, another line from centre of patella to tibial tuberosity and the point of intersection of these lines forms an angle which was measured with the help of goniometer. Result and interpretation: Q angle was bilaterally significant, high in plains than hills, left and right a Q angle in hills was 11.49 and 12.02. In plains left and right Q angle was 12.62 and 13.27. Angle had strong positive correlation with each other and weak positive correlation with BMI and weight. Height may not be a predictor of Q angle.
