For hip rotation testing, where is the fulcrum placed?

Explanation:
The measurement uses a goniometer with the fulcrum placed at the anterior knee, right over the patellofemoral joint (anterior aspect of the patella). This location lines up with the hip’s axis of rotation when the knee is bent to about 90 degrees, so rotating the thigh internal or external causes a clear angular change that the goniometer can capture. Placing the fulcrum elsewhere would not align with the hip’s rotation in this position, whereas options like the femoral neck, medial malleolus, or ASIS would measure a different joint action or produce incorrect angles.
