- Anterior cruciate ligament tear
- Displaced avulsion fracture of the tibial spine
- Meniscal tear
The image shows oval-shaped bone density projecting in the intercondylar notch region. This is a displaced avulsion fracture of the tibial spine, also known as a tibial eminence fracture or ACL avulsion fracture.
- ACL avulsion fractures are often associated with sports or other vigorous physical activity in children 8─13 years of age
- The fracture occurs secondary to relative weakness of incompletely ossified tibial eminence compared to native ACL fibers
Pearls for Urgent Care Management
- Evaluate and document neurovascular status
- Evaluate for more serious considerations such as open fracture, compartment syndrome, or fracture/dislocation in the proximal or distal joint
- Pain medication should be administered, with consideration to potential emergent surgical repair which would require NPO status
- The knee should be immobilized prior to transfer
