FUNCTIONAL OUTCOME OF FLOATING KNEE INJURIES TREATED WITH DIFFERENT MODALITIES IN ADULT PATIENTS: A PROSPECTIVE OBSERVATIONAL STUDY FROM A TERTIARY CARE CENTRE

Abstract

Background: Floating knee injury is a complex high-energy trauma involving ipsilateral fractures of the femur and tibia. It is commonly associated with soft-tissue injury, complications, and prolonged rehabilitation. This study assessed the functional outcome of floating knee injuries treated with different modalities in adult patients. Methods: This prospective observational study was conducted in the Department of Orthopaedics, S.M.S. Medical College and Attached Hospitals, Jaipur. A total of 53 adult patients aged 18–60 years with floating knee injuries were included. Fractures were classified using Fraser classification, and open injuries were graded using Gustilo-Anderson classification. Treatment included intramedullary interlocking nailing, plate fixation, external fixation, or combined methods. Functional outcome was assessed using Karlström–Olerud criteria. Results: The mean age was 36.92 ± 10.48 years, and 84.9% patients were males. Road traffic accident was the commonest mode of injury. Fraser Type I injury was the most frequent pattern. Intramedullary nailing of both bones was the commonest treatment modality. Excellent and good outcomes were observed in 17.0% and 34.0% patients, respectively. Knee stiffness was the most common complication and was significantly associated with poorer outcome. Conclusion: Floating knee injuries commonly affect young males following road traffic accidents. Early stabilisation, appropriate fixation, and structured rehabilitation improve functional outcome.
