This study aims to describe a novel minimally invasive technique for the treatment of acute tibial posterior cruciate ligament (PCL) avulsion fracture.
This retrospective study included seven patients who underwent ultrasound-guided fixation for acute PCL tibial avulsion fractures by using an adjustable-loop device between January 2021 and January 2023. Before the surgery, the maximum diameter, area and displacement distance of the fragments were measured using computed tomography examination. All patients were followed up for at least 12 months, and clinical outcomes were assessed on the basis of range of motion, the International Knee Documentation Committee Score and the Lysholm score.
For the seven patients, the mean maximum diameter, area and displacement distance of preoperative avulsion fragments were 12.7 mm (range, 9.0-48.3), 128 mm (range, 63-256.2) and 5.9 mm (range, 3.8-7.2), respectively. These fractures were fixed using an adjustable-loop suspensory device under ultrasound guidance. Based on x-ray examination during the post-operative follow-up period, all patients had no fracture displacement and fracture unions were confirmed, with a mean union time of 10.28 ± 2.13 weeks (range, 8-14). Based on the knee function assessment at 12-month post-operative follow-up visit, all patients demonstrated excellent clinical outcomes.
Ultrasound-assisted internal fixation using an adjustable-loop device demonstrated satisfactory clinical and radiographic results. This technique has the advantages of being minimally invasive, safe, stable, convenient to operate and thus could be considered as a feasible alternative for the treatment of acute tibial PCL avulsion fractures.

本研究旨在描述一种治疗急性胫骨后交叉韧带（PCL）撕脱骨折的新型微创技术。
这项回顾性研究纳入了2021年1月至2023年1月期间接受超声引导下使用可调环装置固定急性PCL胫骨撕脱骨折的7例患者。术前，通过计算机断层扫描检查测量骨折块的最大直径、面积和移位距离。所有患者均随访至少12个月，并根据活动范围、国际膝关节文献委员会评分和Lysholm评分评估临床结果。
7例患者术前撕脱骨折块的平均最大直径、面积和移位距离分别为12.7毫米（范围9.0 - 48.3）、128平方毫米（范围63 - 256.2）和5.9毫米（范围3.8 - 7.2）。这些骨折在超声引导下使用可调环悬吊装置进行固定。根据术后随访期间的X线检查，所有患者均无骨折移位，确认骨折愈合，平均愈合时间为10.28 ± 2.13周（范围8 - 14周）。根据术后12个月随访时的膝关节功能评估，所有患者均显示出优异的临床结果。
使用可调环装置进行超声辅助内固定显示出令人满意的临床和影像学结果。该技术具有微创、安全、稳定、操作方便等优点，因此可被视为治疗急性胫骨PCL撕脱骨折的一种可行替代方法。
