Passive medial rotation in prone position

The subject lies in the prone position with both knees flexed to a right angle. The examiner encircles both heels and performs a bilateral medial rotation. The range of movement is assessed by the twisted position of the feet.This test compares the range of internal rotation.

Common pathological situations:

• Lateral pain usually indicates a lesion of the lateral coronary ligament.
• An increased range of movement in the prone position is indicative of laxity of the anterior and posterior cruciate ligaments and of the dorsolateral part of the joint capsule.
