Short-term Clinical Outcome of Surgically Managed Acute Floating Knee Injury.

INTRODUCTION

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.

MATERIALS AND

METHODS

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.

RESULTS

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.

CONCLUSION

Floating knee injury is a severe and rare injury associated with significant morbidity. An individualised approach in management results in a satisfactory outcome.
