Aims Fractures of the distal femur are an important cause of morbidity. Their optimal management remains controversial. Contemporary implants include angular-stable anatomical locking plates and locked intramedullary nails (IMNs). We compared the long-term patient-reported functional outcome of fixation of fractures of the distal femur using these two methods of treatment. Patients and Methods A total of 297 patients were retrospectively identified from a State-wide trauma registry in Australia: 195 had been treated with a locking plate and 102 with an IMN. Baseline characteristics of the patients and their fractures were recorded. Health-related quality-of-life, functional and radiographic outcomes were compared using mixed effects regression models at six months and one year. Results There was a clinically relevant and significant difference in quality-of-life at six months in favour of fixation with an IMN (mean difference in EuroQol-5 Dimensions Score (EQ-5D) = 0.12; 95% CI 0.02 to 0.22; p = 0.025). There was weak evidence that this trend continued to one year (mean difference EQ-5D = 0.09; 95% CI -0.01 to 0.19; p = 0.073). There was a significant although very small reduction in angular deformity using an IMN (mean difference -1.02; 95% CI -1.99 to -0.06; p = 0.073). There was no evidence that there was a difference in any other outcomes at any time point.
