title: Open bicondylar Hoffa fracture associated with extensor mechanism injury.
abstract: Two cases of open bicondylar Hoffa fracture of the knee associated with extensor mechanism injury are described in two active young patients with multiple fractures. The level of the fracture was determined by the proximal insertion of the posterior cruciate ligament and anterior cruciate ligament in the medial and lateral condyle. The level of the extensor mechanism injury was determined by the degree of flexion of the knee at the moment of impact. No ligament or meniscal tears were found. Open reduction and internal fixation with four lag screws and bone-to-tendon repair of the patellar and quadriceps tendon gave excellent results after more than 2 years of follow-up. The mechanism of injury and the therapeutic implications are discussed, and the literature is reviewed.
