Modified fixations for distal femur fractures following total knee arthroplasty: a biomechanical and clinical relevance study

Purpose Distal femur fractures adjacent to total knee arthroplasty are a rare yet complex problem. Recently, extramedullary locking plate and retrograde intramedullary nail fixations have become popular options, but the complication rates associated with these procedures are 15–20 %. Modified fixations were assessed in an effort to reduce complications from unstable periprosthetic fractures.
