Final answer:
The Q angle is the angle between a line connecting the most distal aspects of the medial and lateral femoral condyles and a plane perpendicular to the long axis of the femur. It is used to assess knee joint alignment and potential injury risk.
Step-by-step explanation:
The question refers to the angle between a line connecting the most distal aspects of the medial and lateral femoral condyles and a plane that is perpendicular to the long axis of the femur. This angle is known as the Q angle. The Q angle is measured to assess the alignment and stress on the knee joint. It is used in biomechanics and orthopedics to evaluate joint stability and potential injury risk. The average Q angle for males is between 10 to 14 degrees, while for females it is between 15 to 17 degrees.
