We evaluated the functional and radiologic outcomes after stabilization of distal femoral fractures using the distal femoral nail and a less invasive stabilization system to determine if the new implants are superior to other implants (especially the condylar blade plate) regarding the rates of axial deviation, nonunion, and infection and if one of these new implants (Less Invasive Stabilization System, or distal femoral nail) is superior to the other. Two groups, each with 16 patients, were documented prospectively and the results were compared. To record the findings objectively, the Lysholm-Gillquist score was used. A conversion procedure was done in two patients in the plate group and one patient of the nail group. At the 1-year followup mobility of the knee was on average 110 degrees in the plate group and 103 degrees in the nail group. The Lysholm-Gillquist score did not show any significant differences between the groups. There were clinically relevant varus or outer rotation deviations in three patients in the plate group and two patients in the nail group. The two minimally invasive implants used were good in terms of technique and outcome for treatment of distal femoral fractures and did not differ significantly for epidemiology, fracture type, conversion procedures, infection rate, malalignments, and subjective and objective findings at the 1-year followup. They were also superior to the condylar plate in terms of infection and axial malalignments.
