摘　　要：BACKGROUND The phrase “floating knee is a flail knee joint,” referring to ipsilateral femoral and tibial fractures,was first used by Blake and Mc Bryde in 1975.This condition is often caused by a high-energy trauma with often extensive injury to the soft tissues,and is accompanied by life-threatening systemic complications,including head,chest or abdominal injuries and a high incidence of fat embolism.Floating knee is a severe and uncommon injury pattern.CASE SUMMARY A 27-year-old man sustained multiple injuries when the electric motorcycle he was riding was hit by a van.His injuries included traumatic hypovolemic shock,comminuted and open type II fractures of the left femoral shaft,fracture of the right femoral shaft,comminuted fracture of the bilateral tibial and fibular shaft,and multiple lacerations and abrasions on his forehead,lower lip,neck and limbs.The diagnosis was simultaneous bilateral floating knee complicated with soft tissue injuries.After emergency treatment and the exclusion of life-threating complications,open reduction and internal fixation were successfully performed using plates and screws in the bilateral femoral and tibial shafts.CONCLUSION Simultaneous bilateral floating knee is a rare and severe injury pattern.The treatment is challenging,and complications.We present a case report of a young adult who suffered from bilateral floating knees during road traffic accident.We also offer our treatment experience of this complex injury and review past literature.
