| Summary: | Metaphyseal cones are frequently used in revision total knee arthroplasties (TKAs). However, during subsequent aseptic re-revisions, removing a well-fixed cone can be difficult. One innovative option is to retain the well-fixed cone and cement a new, stemmed revision component through the retained cone, yet minimal data exist on this technique. We describe a technique for retaining a well-fixed cone during re-revision TKA and report outcomes in 6 patients with 6 well-fixed metaphyseal cones. At a mean of 4 years follow-up, no retained cones with a new femoral or tibial component with stems were revised and there was no radiographic evidence of aseptic loosening. These early data suggest that retaining a well-fixed cone can be safe in re-revision TKA to minimize morbidity associated with cone removal. Level of evidence: IV (retrospective study). |
