This MRI case demonstrates many of the important injuries seen in association with complete ACL tear including;

• ACL instability - anterior tibial translation
• impaction contusions of the lateral femoral sulcus and posterior tibial plateau
• high-grade posterolateral corner injury including arcuate ligament complex injury, popliteus tendon strain, soleus tendon and biceps femoris fibular avulsions.
• high-grade lateral and anterolateral capsular injury with Segond fracture
• high-grade tear of the medial collateral ligament with the meniscotibial attachment remaining intact
• discontinuous bucket-handle tear of the medial meniscus
• lateral meniscal tears including an outer fragment of the meniscal body flipped into the tibial recess
• 7 mm region of posterior tibial delaminated cartilage underlying the posterior horn of the lateral meniscus
