For lateral knee positioning, how should the unaffected leg be positioned?

In a lateral knee positioning, the proper placement of the unaffected leg is crucial for achieving accurate imaging and minimizing patient discomfort. Positioning the unaffected leg crossed over anteriorly allows for better visibility of the knee joint and minimizes any superimposition that could obscure the area of interest. This helps in obtaining a clear lateral view of the knee, which is essential for assessing its structures, including the femur, tibia, fibula, and surrounding soft tissues.

This option also provides stability and comfort to the patient, aiding in maintaining the required position during the imaging process. It positions the knee in a way that allows for optimal alignment and lessens the risk of motion artifacts.
