Stacked-Cone Constructs for Extensive Tibial and/or Femoral Bone Loss in Complex Primary and Revision TKA: A Multicenter Analysis of 84 Cases

This study investigates the 5-year outcomes of stacked metaphyseal cone constructs used to manage extensive tibial and/or femoral bone loss during complex primary or revision total knee arthroplasty (TKA). The authors found that while the constructs demonstrated a high survivorship rate free from aseptic loosening (91.7%), all-cause reoperations and revisions were relatively common, highlighting the challenges associated with this patient population.
