Variation of the Q angle with sex in adult population.
The data revealed a remarkable difference in the Q angle between males and females with higher values in females. Each column represents the mean Q angle ± standard error of the mean (SE). **P<0.01 (t-test).
Fig 3.
Variation of Q angle with respect to height in males (A) and females (B). A columnar representation for the relationship between the mean Q and the height of in males (A) and in females (B). Values are mean Q angle ± standard error (SE). There is a significant increase in Q angle as the condylar distance increases in both sides. *P<0.05, **P<0.01.

Variation of the Q angle with dominant side in adult population.
(A) right side dominant volunteers showed no significant differences. (B) left side dominant volunteer with the results displayed no significant difference. Each column represents the mean Q angle ± standard error of the mean (SE).
Fig 5.
Variation of Q angle with condylar distance in males (A) and females (B). A columnar representation for the relationship between the mean Q and the condylar distance of the femur in males (A) and in females (B). Values are mean Q angle ± standard error (SE). There is a significant increase in Q angle as the condylar distance increases in both sides. *P<0.05, **P<0.01.
