Abstract：
OBJECTIVE: To assess the clinical efficacy of arthroscopic treatment for posterior cruciate ligament (PCL) tibial avulsion fractures using high-intensity suture binding combined with button plate suspension fixation.
METHODS: We retrospectively analyzed clinical data from 32 patients with PCL tibial avulsion fractures treated at our hospital from July 2020 to August 2023. We recorded operation time, intraoperative and postoperative complications, and used imaging to assess fracture reduction and healing. Pain and knee function were evaluated using the Visual Analogue Scale (VAS), range of knee motion, Lysholm score, and International Knee Documentation Committee (IKDC) score.
METHODS: Case series; Level of evidence, 4.
RESULTS: All patients were followed for 6 to 18 months, averaging 13.6 months. All incisions healed successfully without postoperative complications. X-rays taken on the first postoperative day showed satisfactory fracture reduction. Three-month post-surgery imaging confirmed healed fractures and no internal fixation failures. At the final follow-up, knee function was well recovered, with only one patient exhibiting a positive posterior drawer test of degree I. Furthermore, the mean VAS score was 0. 5 (range 0.0 to 1.0), active knee extension was 2. 2° (range 0.0 to 5.0), and active knee flexion was 137.7° (range 130.0 to 145.0). The mean Lysholm score was 91.5(range 89.3 to 94.0), and the IKDC score averaged 83.8 ± 3.7, and these outcomes showed statistically significant improvement from preoperative levels (P < 0.001).
CONCLUSIONS: Arthroscopic high-intensity suture binding combined with button plate suspension fixation for PCL tibial avulsion fractures offers several benefits: it is minimally invasive, results in less postoperative pain, enables earlier functional exercise, and provides satisfactory clinical outcomes with fewer complications.

摘要：
目的：评价关节镜下高强度缝线结合纽扣钢板悬吊固定治疗后交叉韧带(PCL)胫骨止点撕脱骨折的临床疗效。
方法：我们回顾性分析了2020年7月至2023年8月在我院接受治疗的32例PCL胫骨撕脱骨折患者的临床资料。我们记录了手术时间,术中和术后并发症，并使用影像学评估骨折复位和愈合。使用视觉模拟评分法(VAS)评估疼痛和膝关节功能,膝盖运动范围,Lysholm得分,国际膝关节文献委员会（IKDC）评分。
方法：案例系列；证据水平，4.
结果：所有患者随访6~18个月，平均13.6个月。所有切口均成功愈合，无术后并发症。术后第一天的X线片显示骨折复位满意。术后3个月影像学证实骨折愈合，没有内固定失败。在最后的后续行动中，膝关节功能恢复良好,只有一名患者表现出I度后部抽屉试验阳性。此外，平均VAS评分为0。5（范围为0.0到1.0），积极的膝盖伸展是2。2°（范围0.0到5.0），膝关节活动度为137.7°（范围130.0至145.0）。Lysholm平均得分为91.5（范围为89.3至94.0），IKDC评分平均为83.8±3.7，这些结果与术前水平相比有统计学意义的改善（P<0.001）。
结论：关节镜下高强度缝合结合纽扣钢板悬吊固定治疗PCL胫骨止点撕脱骨折有几个好处：微创，减少术后疼痛，启用早期功能锻炼，并提供令人满意的临床结果，并发症较少。
