Patients with persistent lateral knee pain and instability should always be evaluated closely, so today we’re sharing a simple 4-step guide to scanning the lateral patellotibial ligament.

1. Place the patient in a supine position with the knee flexed 90°.
2. Position the transducer longitudinal on the lateral aspect of the knee, bridging the patella and tibia. 
3. Identify the lateral patellotibial ligament and its trilaminar appearance running from the patella to the tibia.
4. Other anatomical structures in this view are the synovium and Hoffa’s fat pad, which is located underneath the patellotibial ligament.
