The authors devised a double-bundle posterior cruciate ligament reconstruction technique in combination with a single-sling method. However, the double-bundle technique needs more simplicity and a decreased possibility of failure.
A novel surgical technique of transtibial double-bundle posterior cruciate ligament reconstruction using a single-sling method with a tibialis anterior allograft, previously introduced, produces satisfactory results.
Case series; Level of evidence, 4.
Twenty-one patients who underwent double-bundle transtibial isolated posterior cruciate ligament reconstruction using a single-sling method between July 2003 and September 2007 were enrolled in this study. The exclusion criteria applied were (1) a multiligamentous injury, (2) posterior cruciate ligament reconstruction previously performed using another technique, and (3) the presence of any additional injury capable of affecting knee stability. The Lysholm and International Knee Documentation Committee (IKDC) knee scales were used for the clinical outcome evaluation. Stability was evaluated using a KT-2000 arthrometer. The evaluation was performed by comparing preoperative and last follow-up results.
Nineteen men and 2 women were enrolled, with a mean follow-up of 49.2 months (range, 25-73 months). The mean Lysholm score was 53 ± 5.3 (range, 34-68) preoperatively and improved to 83.5 ± 13 (range, 61-97) at the last follow-up after surgery (P < .001). The IKDC score also improved from preoperative (0 A, 0 B, 7 C, 14 D) to final follow-up (8 A, 9 B, 3 C, 1 D; P < .001). Mean side-to-side difference in posterior translation, measured using the KT-2000 arthrometer, was 13.5 ± 1.2 mm preoperatively and 3.4 ± 0.8 mm at last follow-up evaluations (mean 51.7 months postoperatively).
After follow-up for longer than 24 months, the transtibial double-bundle posterior cruciate ligament reconstruction with a single sling was found to produce satisfactory clinical and stability results, which indicates that the described technique should be viewed as a viable alternative.
作者设计了一种结合单吊带法的后十字韧带（PCL）双束重建技术。然而，双束技术需要更加简化，并且降低失败的可能性。
先前介绍的一种经胫骨双束 PC L 重建的新型手术技术，采用胫骨前肌同种异体移植物的单吊带方法，可产生满意的结果。
病例系列；证据水平，4 级。
2003 年 7 月至 2007 年 9 月期间，21 例患者接受了经胫骨双束单吊带法孤立性 PCL 重建，排除标准为：（1）多韧带损伤；（2）先前采用其他技术进行的 PCL 重建；（3）存在任何其他可能影响膝关节稳定性的损伤。临床结果评估采用 Lysholm 和国际膝关节文献委员会（IKDC）膝关节评分。采用 KT-2000 关节测量仪评估稳定性。通过比较术前和末次随访结果进行评估。
纳入 19 名男性和 2 名女性，平均随访 49.2 个月（范围 25-73 个月）。术前 Lysholm 评分为 53 ± 5.3（范围 34-68），术后末次随访时改善至 83.5 ± 13（范围 61-97）（P<.001）。IKDC 评分也从术前（0 A、0 B、7 C、14 D）改善至末次随访（8 A、9 B、3 C、1 D；P<.001）。使用 KT-2000 关节测量仪测量的后向平移侧间差值，术前为 13.5 ± 1.2 mm，末次随访时为 3.4 ± 0.8 mm（平均术后 51.7 个月）。
随访时间超过 24 个月后，发现经胫骨双束 PC L 重建结合单吊带可获得满意的临床和稳定性结果，表明该技术可作为一种可行的替代方法。
