The purpose of this study was to assess tibial post fracture between highly cross-linked polyethylene (HXPE) and conventional polyethylene inserts in consecutive posterior-stabilized (PS) total knee arthroplasty (TKA) over a minimum 10-years follow-up period.
Between July 2008 and December 2011, a consecutive series of 3264 primary TKAs was performed in 2098 patients using a PS total knee prosthesis at a single institution. The final cohort was classified into the HXPE group (792 cases) and the conventional group (2113 cases) according to insert material used during the procedure.
The mean follow-up period was 11.4 years in the HXPE group and 11.8 years in the conventional group. Both cases of tibial post fracture occurred in the HXPE group, a complication rate of 0.25%. These two cases required replacement with a thicker tibial insert with retention of the femoral and tibial components. There were no cases of tibial post fracture in the conventional group.
There was no difference in tibial post fracture rate between the HXPE group and the conventional group in PS TKA on long-term follow-up.

本研究旨在评估在至少 10 年的随访期间，在后稳定型（PS）全膝关节置换术中连续使用高交联聚乙烯（HXPE）和传统聚乙烯衬垫的胫骨后柱骨折情况。
在 2008 年 7 月至 2011 年 12 月期间，在一家机构中对 2098 例患者连续进行了 3264 例初次全膝关节置换术，使用 PS 全膝关节假体。最终队列根据术中使用的插入物材料分为 HXPE 组（792 例）和传统组（2113 例）。
在 HXPE 组的平均随访期为 11.4 年，在传统组的平均随访期为 11.8 年。两例胫骨后柱骨折均发生在 HXPE 组，发生率为 0.25%。这两例需要更换更厚的胫骨衬垫，保留股骨和胫骨组件。在传统组中没有胫骨后柱骨折的病例。
在 PS TKA 的长期随访中，HXPE 组和传统组的胫骨后柱骨折率没有差异。
