BACKGROUND: Floating knee, referred to as ipsilateral fractures of the femur and tibia, is usually associated with several complications and mortality. This study was designed to present our experience with treatment of this injury throughout; age, sex, mechanism of injury, associated injuries, method and results of treatment, and complications of floating knee are discussed.
MATERIALS AND METHODS: This retrospective study was performed between January 2006 and December 2011. All patients with floating knee injuries who were admitted to the referral educational hospitals were included. The information about the 238 cases of floating knee injuries were gathered through the 254,620 trauma files and after excluding 18 patients who died within 6 months, the remaining files were studied and the target information was recorded.
RESULTS: The most frequent age group was 20-29 years (44.5%). The floating knee injuries were more common in males (85.5%). Type (D) according to "the classification of Letts and Vincent" was observed in 38.9% cases. The most frequent mechanism of injury was car to motorcycles accidents (48.2%). The most common associated injury was pelvic fractures (86.8%). Open reduction and internal fixation was the common type of treatment (70%). The most common early and late complications were knee hemarthrosis in 31 cases (14%) and knee osteoarthritis in 30 cases (13.6%), respectively. Death during the 5 years follow up was due to circulatory disruption, followed by deep vein thrombosis (61%). There was a significant relation between the age and outcomes as it worsens with age (P-value < 0.05).
CONCLUSION: This study revealed that the complication rate associated with floating knee injuries remained high, regardless of the used treatment regimen and surgeons should focus on reducing complications while treating it.
