Distal tibial metaphyseal allograft cone for proximal tibial bone loss in revision knee arthroplasty – A novel technique

摘要

Large bone defects in femur or tibia are common at the setting of revision knee arthroplasty. Filling up the defect remains a challenging problem to the orthopaedic surgeons. A variety of options are available to fill up these defects depending upon the type of defect. We report a case of large contained defect in proximal tibia managed with distal tibial metaphyseal allograft cone. We also discuss the operative details and the advantages of using the allograft.
