AbstractKnee injuries are common in children, but epiphyseal and physeal injuries involving the distal femur and proximal tibia are relatively rare. This can make diagnosis and evaluation of pediatric knee injuries challenging. Pediatric knee physeal injuries can also be complicated by vascular injuries with potentially devastating consequences, and thus, a heightened suspicion for these injuries is indicated. Distal femoral and proximal tibial physeal injuries can be diagnosed with plain radiographs or with advanced imaging if the initial findings are equivocal. Physeal fractures of the distal femur and proximal tibia can be managed nonsurgically if nondisplaced or surgically with cannulated screw fixation or smooth, percutaneous pin fixation. Tibial tubercle injuries can have point tenderness or an extensor lag, are diagnosed with plain radiographs, and are often managed with physeal-sparing cannulated screw fixation. These injuries have an increased risk of compartment syndrome. Tibial eminence fractures are epiphyseal avulsion injuries caused by traction from the anterior cruciate ligament. Arthroscopic and open techniques for reduction and stable fixation yield good outcomes. Patellar sleeve injuries are often misdiagnosed and may require advanced imaging for diagnosis. They represent pediatric extensor mechanism injuries that often necessitate open reduction and fixation or patellar tendon advancement. Understanding the relevant anatomy, diagnosis, and management options can help guide the treating physician in the management of the fractures of the pediatric knee.
