title: Floating knee injuries: a high complication rate.
abstract: Floating knee injuries are usually associated with complications and mortality, regardless of the treatment regimen. Orthopedic surgeons typically recommend various treatment regimens, especially aggressive and early stabilization of both femoral and tibial fractures. Some authors have reported that the complication and mortality rates remain high regardless of the treatment regimen used. The purpose of this retrospective study was to review the long-term results of treatments for floating knee injuries performed at our institution, and also to calculate the distribution of fracture types within patient age groups and the association with complications related to floating knee injury. We retrospectively reviewed medical records and radiographs of 419 floating knee injuries treated for postoperative complications from November 1987 to April 2003. Of the 419 patients with floating knee injuries, 104 (24.8%) developed complications. The result showed that the complication rate was associated with fracture type (open fracture [32.2%; P<.001], Fraser type IIc [36.8%; P<.001], tibial plateau [28.6%; P=.037], and distal tibia [28.6%; P=.035]). This study revealed that the complication rate associated with floating knee injuries remained high, regardless of the treatment regimen used. Surgeons should focus on reducing complications while treating floating knee injuries.
