With the knee over the side of the examining table, one hand stabilizes the thigh while the other applies an external rotation force across the knee, through the foot / ankle.
Indication of a posterolateral knee injury is best visualized by tibial tubercle motion. An increase of posterolateral rotation should be compared to the normal contralateral side. Increases of 10° - 15° are indicative of a severe PLC injury.

Externally rotate the leg while watching for external rotation of the tibia tubercle in relation to femur.
