Medial Coronary LigamentPositive Tests

Medial Coronary LigamentPositive Tests

MI: Passive Lateral Rotation is painful (this is a major indicator)

AUX: Passive Flexion of the Knee is painful and often limited

AUX: Passive Extension of the Knee is painful and often limited

Heat Test: The injured knee is often hot or at least warmer then the good knee

• Lateral coronary ligament is not attached to Lateral Collateral Ligament

• Lateral coronary injuries often mistaken for IT band strain, lateral hamstring injury, meniscus tear

• At times feels like the knee will collapse
