BACKGROUND
Distal femoral fracture is a rare, but significant, postoperative complication of anterior cruciate ligament reconstruction. However, there has not been a reported case of periprosthetic total knee arthroplasty fracture associated with a previous anterior cruciate ligament repair.
CASE PRESENTATION
We report the case of a 51-year-old white man with a history of total knee arthroplasty and remote anterior cruciate ligament reconstruction, who presented with a distal femoral periprosthetic fracture at the site of a previous anterior cruciate ligament augmentation staple.
CONCLUSIONS
Based on these findings, it may be important to consider removal of previous anterior cruciate ligament hardware prior to total knee arthroplasty to reduce risk of periprosthetic fracture, which should be determined on a patient-specific basis.
背景
股骨远端骨折是前交叉韧带重建术后一种罕见但严重的并发症。然而，此前尚无关于与既往前交叉韧带修复相关的假体周围全膝关节置换骨折的报道。
病例报告
我们报告了一例51岁白人男性病例，该患者有全膝关节置换和既往前交叉韧带重建史，其股骨远端假体周围骨折发生在既往前交叉韧带增强钉的位置。
结论
基于这些发现，在进行全膝关节置换之前考虑移除既往前交叉韧带固定装置以降低假体周围骨折风险可能很重要，这应根据患者具体情况确定。
