Kneed a Diagnosis
This shows bone bruising (arrows) which is highly suggestive of an ACL tear where the anterior femoral condyle hits the posterior tibia. ACL tears are often seen in direct trauma and noncontact athletic injuries. Typical mechanisms include rotation and lateral bending (valgus stress) on the knee or sudden deceleration and direction change (cutting).
