Supracondylar femoral fractures above total knee arthroplasty remain a treatment challenge. Complication rates as high as 30% are associated with both nonoperative and operative treatment. Conventional plate fixation and rigid intramedullary nail fixation has improved the treatment of these fractures. However, problems still exist in the setting of a short distal femoral block and/or significant osteoporosis. Less Invasive Stabilization System (L.I.S.S.) fixation has been utili/ed for the treatment of supracondylar femoral fractures above total knee arthroplasty. Multiple fixed angle screws give optimal fixation around the femoral component. Advantages appear to include maintenance of distal femoral fixation, low infection, and low need for bone grafting.
