Final answer:
The Q-angle is a measurement indicating femoral anteversion, which is the lateral deviation of the femur from the vertical line of the tibia. Females typically have a larger Q-angle due to their wider pelvis. A larger Q-angle in females may increase the risk of developing patellofemoral syndrome.
Step-by-step explanation:
The Q-angle is a measurement used to indicate femoral anteversion, which is the amount of lateral deviation of the femur from the vertical line of the tibia. The Q-angle is typically 10-15 degrees and is larger in females due to their wider pelvis. Females with a larger Q-angle may be more vulnerable to developing patellofemoral syndrome.
