Patient lies supine, leg externally rotated, knee 20-30 flexed.
Place the transducer on a oblique plane in orientation of the medial collateral ligament over the femoro tibial joint.
MM: medial meniscus
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.
