Aseptic loosening has long been an associated etiology for revision total knee arthroplasty (TKA).
This case series investigates commonalities between 9 patients who underwent revision TKA and were found to have complete debonding at the cement-implant interface of a femoral and/or tibial component within the past 2 years.
Only 3 preoperative radiographs were indicative of aseptic loosening, and all patients had an infectious etiology ruled out.
This case series and other similar reports suggest that there may be a growing concern for debonding as a modern form of aseptic loosening. Further research through American Joint Replacement Registry and other national databases will need to be conducted to better understand if this is truly a new cause for concern after TKA and how it may be best prevented.
无菌性松动长期以来一直是翻修全膝关节置换术（TKA）的相关病因。
本病例系列研究了9例接受翻修TKA的患者的共同特征，这些患者在过去2年内被发现股骨和/或胫骨部件的骨水泥-植入物界面完全脱粘。
只有3张术前X光片显示无菌性松动，所有患者均排除感染病因。
本病例系列及其他类似报告表明，作为无菌性松动的一种现代形式，脱粘可能越来越受到关注。需要通过美国关节置换登记处和其他国家数据库进行进一步研究，以更好地了解这是否真的是TKA术后一个新的关注原因以及如何最好地预防它。
