BACKGROUND: This study evaluated the outcomes of surgical management of ipsilateral femoral and tibial fractures in adults. METHODS: Fifteen patients (13 men, 2 women; mean age, 34.8 years; range, 18 to 65 years) were enrolled in this study. The fractures types were classified according to the classification by Fraser et al. as follows: type I (5), type IIa (3), IIb (4), IIc (3). Femur fractures were treated using locked intramedullary nails, plate-screws, or dynamic condylar screws, and tibia fractures were treated with an external fixator (in open fractures), or plate-screws, and locked intramedullary nailing. The mean follow-up duration was 2.2 years (range, 1.3 to 4 years). RESULTS: The extent of bony union according to the Karlstrom criteria was as follows: excellent, 8; good, 4; acceptable, 2; poor, 1. CONCLUSIONS: The associated injuries and type of fracture (open, intra-articular, comminution) are prognostic factors in a floating knee. The best management of the associated injuries for good final outcome involves intramedullary nailing of both the fractures and postoperative rehabilitation.
