Floating knee injury or ipsilateral fractures of both femur and tibia is a severe injury caused by high-velocity trauma and is often associated with significant and occasionally life-threatening complications. The objectives of this study were to evaluate the early clinical outcomes of acute floating knee injury and to observe the complications related to the treatment.
A total of 15 patients with acute floating knee injuries were included in the study. Baseline data were noted, including demographic details, type of fracture, mode of injury, surgery performed, associated injuries, and complications. For a total duration of 18 months, all the patients were followed up. Karlström and Orleud's criteria assessed the clinical outcome at the final follow-up.
Most (66.7%) patients were Fraser's type I fractures. The mean duration of the bone union of the femur was 7.79 months, whereas for the tibia, it was 8.21 months. The mean time for weight bearing was 9.71 months. Fraser's type I had the highest mean range of motion (115.50°). The most common early complication was knee haemarthrosis, and the most common late complication was delayed union.
Floating knee injury is a severe and rare injury associated with significant morbidity. An individualised approach in management results in a satisfactory outcome.
浮动膝损伤，即同侧股骨和胫骨骨折，是一种由高速创伤导致的严重损伤，常伴有严重且偶尔会危及生命的并发症。本研究的目的是评估急性浮动膝损伤的早期临床结果，并观察与治疗相关的并发症。
本研究共纳入15例急性浮动膝损伤患者。记录基线数据，包括人口统计学细节、骨折类型、损伤方式、所进行的手术、相关损伤和并发症。对所有患者进行了为期18个月的随访。在最后一次随访时，采用卡尔斯特伦和奥勒德标准评估临床结果。
大多数（66.7%）患者为弗雷泽I型骨折。股骨骨愈合的平均时间为7.79个月，而胫骨为8.21个月。平均负重时间为9.71个月。弗雷泽I型的平均活动范围最大（115.50°）。最常见的早期并发症是膝关节血肿，最常见的晚期并发症是骨不连。
浮动膝损伤是一种严重且罕见的损伤，伴有明显的发病率。个体化的治疗方法可取得满意的结果。
