The purpose of this study was to determine the outcomes of the placement of a pin tracker in the distal femur in robotic-assisted total knee arthroplasty (TKA) over a minimum follow-up period of 1 year. A consecutive series of 81 TKAs were performed in 59 patients using a robotic-assisted system (Mako) at our hospital. The mean follow-up period was 1.1 years (range, 1–1.2 years). No periprosthetic fracture at a pin tracker site was reported at a minimum of 1 year of follow-up. No patients reported minor or major complications associated with the distal femoral pins. In addition, unicortical pin-site drilling marks in all patients disappeared on one-postoperative-year follow-up radiographs. Our technique, which used unicortical pin placement in the distal femur in robotic-assisted TKA, demonstrated that it was a safe and reliable method at a minimum follow-up period of 1 year. The level of evidence is IV.

远端股骨跟踪器销钉放置可防止机器人辅助全膝关节置换术中延迟销钉束引起的骨折:至少 1 年随访结果

本研究的目的是确定在机器人辅助全膝关节置换术 (TKA) 中在股骨远端放置钉跟踪器在最短 1 年的随访期内的结果。我们医院使用机器人辅助系统 (Mako) 对 59 名患者进行了连续 81 次 TKA。平均随访时间为 1.1 年(范围:1-1.2 年)。在至少 1 年的随访中,未报告针追踪器部位发生假体周围骨折。没有患者报告与远端股骨钉相关的轻微或严重并发症。此外,所有患者的单皮质针位钻孔痕迹在术后一年的随访X光照片中消失。我们的技术在机器人辅助 TKA 中使用单皮质针放置在股骨远端,在至少 1 年的随访期内证明这是一种安全可靠的方法。证据级别为IV。
