UNLABELLED
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.

干骺端锥体常用于全膝关节置换翻修术（TKA）。然而，在随后的无菌翻修中，取出固定良好的锥体可能会很困难。一种创新的选择是保留固定良好的锥体，并通过保留的锥体用骨水泥固定一个新的带柄翻修部件，但关于该技术的数据极少。我们描述了一种在TKA翻修术中保留固定良好的锥体的技术，并报告了6例保留了6个固定良好的干骺端锥体患者的结果。平均随访4年，没有对带有新的带柄股骨或胫骨部件的保留锥体进行翻修，也没有影像学证据表明存在无菌性松动。这些早期数据表明，在TKA翻修术中保留固定良好的锥体可能是安全的，可将与锥体取出相关的发病率降至最低。
