Patient Positioning
Patient lies supine, leg internally rotated, knee 20-30 flexed.
Probe Positioning
Place the transducer on a sagittal plane over the peroneal head (easy to palpate) in orientation of the medial collateral ligament over the femorotibial joint.
Note: Examine the entire length of the ligament by sweeping the probe cranially and distally. Check the medial collateral ligament during valgus stress (integrity?) and compare it with the opposite knee.
