Background: Floating knee is a condition resulting from high energy trauma usually associated with minor to life threatening injuries making it challanging to treat There are no studies available in literature describing cross leg sitting and squatting after surgical management of floating knee. This study analyzes prognostic factors, plan of management, functional outcomes (special attention to squatting and cross legged sitting), complications. Materials and Methods: 52 patients with floating knee injuries treated over a period of 3 years were included in this study. The study followed an algorithmic approach for the management. Femur fractures were fixed before fixing the tibia according to fracture type that was classified by Fraser classification after the stabilization of patient. The mean followup duration was 21 ± 6 months. The outcome was assessed using Karlstrom criteria after bony union. Results: The study consists of majority (46) of male. Thirty three patients had some types of significantly associated injury. The mean postoperative range of motion of the knee was observed to be 97° ± 27°. Twenty one patients showed excellent results, whereas 17, 8, and 6 patients had good, fair, and poor results, respectively, as per Karlstrom criteria. Knee pain, stiffness, infection, nerve palsy, delayed union, and nonunion were some of the complications observed. Cross legged sitting was possible in 40 patients and squatting in 31. Conclusion: The prognosis of floating knee injury is dependent on factors such as type of fracture, soft tissue condition, and management. Excellent outcomes following these injuries can be achieved with individualized plan of management by multidisciplinary team.
