Posterior cruciate ligament (PCL) injury has a reported incidence of 3-20 %. PCL reconstruction is aimed at reducing onset of premature articular degeneration and improving function. Numerous operative techniques have been described with varying degrees of result consistency.
We evaluated 15 patients treated for isolated primary posterior cruciate ligament injury with a mean follow-up of 4.1 years (range one to nine). Post-reconstruction clinical assessment included the Lysholm and Tegner knee scoring scale, international knee documentation committee (IKDC) ligament evaluation, and KT2000 arthrometer assessment.
On the Lysholm knee score 11 patients (73 %) had excellent results, three patients (20 %) had good results and one patient (7 %) had a poor result. On the Tegner activity score the majority of patients scored 7-8 with a return to high level sports. At the final follow-up, the post-reconstruction IKDC score was normal or nearly normal (A and B) in 14 (93 %) patients, and abnormal (C) in one (7 %) patient. According to KT-2000 arthrometer measurements at final follow-up review, 11 patients (73 %) were rated as normal (A, 0-2 mm), and four patients (27 %) as nearly normal (B, 3-5 mm). These results were independent of age, mechanism of injury, time elapsed to surgical reconstruction, and length of follow-up.
Despite being a technically demanding procedure, the outcomes reported in this study show that single bundle transtibial arthroscopic PCL repair using four strands hamstring autograft provides satisfactory and consistent functional outcomes.
后交叉韧带（PCL）损伤的发病率为 3-20%。PCL 重建的目的是降低关节早期退变的发生率并改善功能。已经描述了许多手术技术，其结果一致性存在差异。
我们评估了 15 例因单纯初次后交叉韧带损伤而接受治疗的患者，平均随访时间为 4.1 年（1-9 年）。重建后的临床评估包括 Lysholm 和 Tegner 膝关节评分、国际膝关节文献委员会（IKDC）韧带评估和 KT2000 关节测量仪评估。
在 Lysholm 膝关节评分中，11 例患者（73%）结果为优，3 例患者（20%）结果为良，1 例患者（7%）结果为差。在 Tegner 活动评分中，大多数患者评分为 7-8 分，可恢复到高水平运动。在最终随访时，14 例患者（93%）的重建后 IKDC 评分正常或接近正常（A 和 B），1 例患者（7%）异常（C）。根据最终随访时 KT-2000 关节测量仪的测量结果，11 例患者（73%）评为正常（A，0-2mm），4 例患者（27%）评为接近正常（B，3-5mm）。这些结果与年龄、损伤机制、手术重建至随访的时间以及随访时间无关。
尽管该手术技术要求较高，但本研究报告的结果表明，采用四股腘绳肌腱自体移植物的单束经胫骨关节镜 PCL 修复术可提供满意且一致的功能结果。
