BackgroundThere is no consensus on the best treatment of distal femoral fractures.Patients And MethodsIn a prospective study, we treated 29 patients with 30 distal femoral fractures with the Less Invasive Stabilization System (LISS) from 1997 to 2000. Almost 1/2 of them had open fractures, 1/3 extraarticular type A and 2/3 articular fractures type C (AO classification) and these had been caused by high-energy trauma with concomitant severe injuries or osteoporosis.ResultsThe follow-up examinations after mean 20 (13-42) months consisted of radiographs, and determination of the Lysholm Knee Score and Knee Society Score (KSS). The outcome correlated with the severity of the fracture, anatomic reduction, exact positioning and fixation of the LISS and concomitant injuries.InterpretationWe found the LISS for treatment of distal femoral fractures of all types to be a safe procedure with good results after careful planning and experience with this surgical technique. There is usually no need for primary cancellous bone grafting.
