Common peroneal nerve (CPN) injury associated with multiple-ligament knee injury is relatively rare. A 38-year-old male presented with left knee pain occurred during ssireum (Korean wrestling). The patient exhibited positive Lachman, grade 3 varus stress, and also positive dial testing at 30°. Sensory loss of some area of left foot and foot drop were observed. Magnetic resonance imaging showed complete anterior cruciate ligament (ACL) rupture and posterolateral corner (PLC) injury. Motor nerve conduction velocity indicated left CPN palsy. ACL and PLC reconstructions were performed 10 days after injury and nerve exploration was done simultaneously. Neurolysis and primary repair were also performed. At 26 months after injury, muscle power of the tibialis anterior and extensor hallucis longus improved to grade 3, and sensation in CPN area recovered to about 60%. There was good stability in injured knee. To the best of our knowledge, this is the first case report describing CPN palsy with multiple-ligament knee injury during ssireum.
