The PCL is fan-shaped, being narrowest in the midportion and fanning out superiorly and, to a lesser extent, inferiorly. The PCL originates on the posterior surface of the tibia and passes superiorly and anteriomedically to insert on the lateral wall of the medial femoral condyle. The PCL consists of a larger anterior band, which is taut in flexion and relaxed in extension, and a smaller posterior band, which is taut in extension and relaxed in flexion.

• A posteriorly directed force on the upper front of a flexed knee

  while the foot is in dorsiflexion.
• Sudden, unexpected hyperextension of the knee
• Patellofemoral pain and recurrent instability
• Mild hemarthrosis (blood in the knee).
