Metaphyseal Fixation for Revision Total Knee Arthroplasty

Initial and long-term metaphyseal fixation is critical for implant survivorship after revision total knee arthroplasty. When bone loss is encountered following removal of primary components or with osteolysis, reconstructive options for small defects include allograft, cement, or augments. Cemented stems may provide early fixation but may not be sufficient in isolation for long-term durability in the setting of metaphyseal bone loss. Bulk allograft, sleeves and cones are the most commonly utilized modalities for metaphyseal fixation in the revision setting, each with their own advantages and disadvantages, with promising results in decreasing the risk of aseptic loosening.
