In a recently published article we reviewed our long term outcomes of TKA in young patients (<55) with end stage OA. The purpose of this study was to identify what additional factors may predict aseptic failure in these young patients.
A retrospective review of all patients in our young TKA database was performed, and included failure only for mechanical wear and loosening.
The IB-II prosthesis, a thin polyethylene (<9 mm), and higher Knee Society functional class at midterm follow-up was associated with higher failure rate.
This study helps better identify the etiology of failed young patient TKA.
在最近发表的一篇文章中，我们回顾了年轻患者（<55岁）终末期骨关节炎全膝关节置换术（TKA）的长期疗效。本研究的目的是确定哪些其他因素可能预测这些年轻患者的无菌性失败。
对我们年轻TKA数据库中的所有患者进行回顾性分析，纳入仅因机械磨损和松动导致的失败病例。
IB-II型假体、薄聚乙烯（<9mm）以及中期随访时较高的膝关节协会功能分级与较高的失败率相关。
本研究有助于更好地确定年轻患者TKA失败的病因。
