Complications are common, and functional outcomes are often poor. This study aimed to evaluate bone healing and to identify factors influencing nonunion and functional results.\n                    <jats:italic>Methods<\/jats:italic>\n                    : This retrospective study included 72 knees, with a mean follow-up of 4.5 years. The primary outcome was bone union. Neurological, vascular and meniscoligamentous injuries were analyzed. Follow-up parameters were clinical, radiological and functional, including the Karlstr\u00f6m and Olerud score.\n                    <jats:italic>Results<\/jats:italic>\n                    : At least one fracture was open in 69% of cases. Mean time to union was 10.5 months for the femur, 7.5 months for the tibia, and 4.4 months for the patella. Nonunion occurred in 68% of femoral fractures, 57% of tibial fractures, and 42% of patellar fractures. Open fractures and tibial vascular injuries were significant predictors of nonunion. Meniscoligamentous injuries were diagnosed in 32% of cases and were more frequent with increasing Ran stage (\n                    <jats:italic>p<\/jats:italic>\n                    = 0.004). Surgical site infection occurred in 30.6% of cases and was significantly associated with open fractures (\n                    <jats:italic>p<\/jats:italic>\n                    &lt; 0.001). Functional outcomes worsened with increasing Ran stage, meniscoligamentous injuries, open fractures, and infection.\n                    <jats:italic>Conclusion<\/jats:italic>\n                    : Floating knee injuries are characterized by prolonged healing, high rates of nonunion and infection, and limited functional outcomes.\n
