Which of the following techniques measures the Q angle?

Question

Quizplus · Accepted Answer

The Q angle measures the degree of lateral deviation of the patella from its normal track in the femoral groove. It is defined as the angle between a line drawn from the anterior superior iliac spine (ASIS) to the center of the patella and a line drawn from the center of the patella to the tibial tuberosity. Therefore, B is the correct choice as it uses the ASIS and midpoint of the patella for the proximal arm and axis, respectively, and the tibial tuberosity for the distal arm.
