To evaluate the effect of newly designed arthroscopic reconstruction of posterior cruciate ligament (PCL) using tibial tendon bolt.
The effects of embedded tendon pin were observed by X-ray of knee joint. From October 2010 to September 2015, 51 PCL injury patients who met the inclusion criteria were enrolled in this retrospective study. The arthroscopically assisted reconstruction of the PCL with tibial tendon bolt was performed on all patients. Visual Analog Scale (VAS) pain score, Tegner activity score, Lysholm score, International Knee Documentation Committee (IKDC) assessment, posterior drawer test (PDT), and KT-1000 activity score were evaluated preoperatively and at 1-year postoperative and 3-year postoperative.
The preoperative, 1-year postoperative, and 3-year postoperative IKDC score (15.8% ± 14.8%, 89.6% ± 5.8%, and 86.8% ± 5.4%), Lysholm score (17.4 ± 10.7, 91.2 ± 2.8, and 88.2 ± 3.1), VAS score (5.8 ± 1.2, 1.3 ± 0.5, and 0.6 ± 0.5), Tegner activity score (1.2 ± 0.8, 8.1 ± 0.8, and 7.4 ± 0.8), and KT-1000 score (15.6 ± 3.6, 4.5 ± 2.4, and 5.4 ± 1.8) were obtained. There were significant differences in these outcomes among preoperative, 1-year postoperative, and 3-year postoperative (all P < 0.0001). After 1- and 3-year surgery, 31 (60.8%) and 26 (51.0%) patients had the negative PDT, indicating that the PCL injury was improved. There were no postoperative complications.
The application of tendon pin fixed by tibial inlay 8-shaped tibial tunnel to reconstruct PCL was an effective, simple, and safe surgical procedure for PCL injury.
评估使用胫骨肌腱螺栓进行新设计的关节镜后交叉韧带（PCL）重建的效果。
通过膝关节 X 射线观察嵌入式肌腱销的效果。2010 年 10 月至 2015 年 9 月，符合纳入标准的 51 例 PCL 损伤患者纳入本回顾性研究。所有患者均行关节镜辅助胫骨肌腱螺栓重建 PCL。术前、术后 1 年和术后 3 年分别采用视觉模拟评分（VAS）疼痛评分、Tegner 活动评分、Lysholm 评分、国际膝关节文献委员会（IKDC）评估、后抽屉试验（PDT）和 KT-1000 活动评分进行评估。
术前、术后 1 年和术后 3 年的 IKDC 评分（15.8%±14.8%、89.6%±5.8%和 86.8%±5.4%）、Lysholm 评分（17.4±10.7、91.2±2.8 和 88.2±3.1）、VAS 评分（5.8±1.2、1.3±0.5 和 0.6±0.5）、Tegner 活动评分（1.2±0.8、8.1±0.8 和 7.4±0.8）和 KT-1000 评分（15.6±3.6、4.5±2.4 和 5.4±1.8）均有显著差异（均 P<0.0001）。术后 1 年和 3 年，31 例（60.8%）和 26 例（51.0%）患者出现阴性 PDT，表明 PCL 损伤得到改善。术后无并发症。
胫骨嵌入式 8 字形胫骨隧道固定肌腱销重建 PCL 是一种治疗 PCL 损伤的有效、简单、安全的手术方法。
