ACL Injury Diagnosis

Orthopedic Surgery

How is an ACL injury diagnosed?

During your first visit, your doctor will talk to you about your symptoms and medical history. He or she will check all the structures of your injured knee, and compare them to your non-injured knee. Most ligament injuries can be diagnosed with a thorough physical examination of the knee.

Other tests which may help your doctor confirm your diagnosis include:

  • X-rays. Although they will not show any injury to your anterior cruciate ligament, x-rays can show whether the injury is associated with a broken bone.
  • Magnetic resonance imaging (MRI) scan. This study creates better images of soft tissues like the anterior cruciate ligament. However, an MRI is usually not required to make the diagnosis of a torn ACL.
