In brief
Anterior cruciate ligament (ACL) avulsion at the intercondylar eminence, though well recognized in the pediatric population, is uncommon in skeletally mature people. Unlike in children, this injury in adults is often associated with soft-tissue trauma such as tears of the meniscus and of other ligaments. X-rays are often diagnostic for avulsion, but MRI is often required to identify concomitant injuries. In adults, surgical repair restores normal ACL function.
