Bilateral Floating Knee Injuries in an Infant: A Case Report and Literature Review

Background: Floating knee injury is defined as ipsilateral fractures of the femur and tibia. It was mostly seen among young men and is generally caused by high-velocity trauma such as motor vehicle accidents and falling from height. Although isolated fractures of the femur or tibia are relatively common in children, floating knee injuries are rare in adolescents and even less frequent in younger children. Case Report: In this study, we reported a case of bilateral floating knee injuries of a 10-month old girl infant. Radiographic examinations revealed diaphyseal fracture of the left femur and proximal metaphyseal fracture of tibia compatible with floating knee injury type B according to the classification proposed by Letts et al. To the best of our knowledge, there was not any previous report of bilateral infantile floating knee injury in the literature. Conclusion: Pediatric floating knee injuries are relatively uncommon and extremely rare among infants. The preferred method of treatment is a surgical fixation for all fractures of all ages.

A retrospective analysis of twenty two cases of floating knee

<p class="abstract"><strong>Background:</strong> With increase in road traffic accidents, incidence of floating knee injuries is increasing day by day. Along with bony injuries, multiorgan injuries are generally present which require urgent intervention. Despite advance in surgical management and implants, achieving a good functional knee still remains a challenge to the surgeons.</p><p class="abstract"><strong>Methods:</strong> This retrospective study was conducted to assess management, functional outcome and complications of patient presenting with floating knee injury to a tertiary care centre. 22 patients with floating knee injury admitted in trauma centre from 2017 to 2019 were analysed and functional assessment was done.<strong></strong></p><p class="abstract"><strong>Results:</strong> Males with mean age 33.5 years were exclusively victims of road traffic accident. 14 patients presented with multisystem injury. After stabilization fractures were fixed with nails/plates/screws. Knee stiffness was most common complication seen in 37% cases. Functional assessment was done using modified Karlstrom Olerud criteria which revealed excellent results in 22.7% cases while poor results in 18.2% cases.</p><p><strong>Conclusions:</strong>Floating knee injury is not merely bony injury but a multisystem injury and should be managed on principles of Damage control Orthopaedics. Regarding bony injuries, achieving union and acceptable range of motion remains the prime target. </p>

Bilateral floating knee: a rare case report with review of literature

<p class="abstract">Floating knee injuries are commonly seen nowadays due to increase in road traffic accidents. However, bilateral presentation of floating knee is a rare injury and challenging to orthopaedicians for a good functional outcome. We hereby present a rare case of bilateral floating knee injury in a 45 year old male treated with open reduction and internal fixation in a staged procedure. Functional assessment was done using modified Karlstrom-Olerud criteria which showed excellent outcome. Union was achieved in approximately 7 months. Decreased knee movements over left side as compared to right side was only complication seen.</p>

Homolateral Hip Dislocation, Floating Hip Injury, and Floating Knee Injury: A Unique Presentation of a Rare Injury

Introduction: Floating joint injury is an unusual injury pattern that is hard to deal with and often caused by high-energy trauma. In this report, a patient had a homolateral floating hip injury (FHI), floating knee injury (FKI), and hip dislocation at our hospital, and there was no case reported before. Case Presentation: A 48-year-old driver who encountered a traffic accident was seen. Radiologic examination revealed acetabulum comminuted fractures and hip joint posterior dislocation with some fracture pieces in the joint space on the left side. The femur, tibia, and fibula were simultaneously disrupted with open trauma of the left calf. Open reduction and screw-plate fixation of the acetabulum fracture, intramedullary nail fixation of the femoral fracture, and external fixator for his tibia and fibula fracture were carried out. Conclusion: The treatment of multiple fractures should focus on life-threatening injuries above all, and then deal with the fractures according to the situation of the patient. Open reduction and internal fixation are priority choices except in some special cases like where soft tissue is in poor condition. Individual therapy and early rehabilitation are effective for homolateral FHI and FKI.
