Avulsion fracture of knee




A 22 year old woman came complaint of pain on the left knee for 1 week. 
She was actually fell down and knee hit the road surface. 
Patient have difficulty in walking & taking the staircase. 

Discussion:

Routine AP & Lateral knee x-ray was done. 
The x-ray showed possibility of avulsion fracture of anterior cruciate ligament. 
The anterior cruciate ligament tearing cause small fragment of bone to break. In this case it involves the bone in the intercondylar notch. 
It is evidence by 2 bony pieces - one large (11mm) and one small (2mm) - seen in the intercondylar notch (red circle).
