The purpose of this study was to compare clinical results of arthroscopic posterior cruciate ligament (PCL) reconstructions using double-loop hamstring tendon autograft and Achilles tendon allograft while preserving the original PCL remnant.
Case-control study of results of treatment.
From September 1997 to December 2000, 36 patients who received only PCL reconstruction were reviewed retrospectively. Of these, 18 patients received autogenous double-loop hamstring tendon reconstruction (group I) and 18 received Achilles tendon allograft reconstruction (group II). The same PCL reconstruction procedure was performed in both groups. At final follow-up at a minimum of 2 years, patients were evaluated by 4 measures: the International Knee Documentation Committee (IKDC) evaluation, Lysholm knee scores, the posterior draw test, and Telos stress radiography.
Between the 2 groups, preoperative demographic factors (age, gender, activity level, and mean duration to surgery) showed no statistically significant difference (P > .05). According to IKDC evaluation of group I, 16 of the 18 knees rated normal or nearly normal, whereas 2 fell into the abnormal category. By the same criteria, 14 of the 18 knees in group II were normal to nearly normal, 3 were abnormal, and 1 was severely abnormal. IKDC scores showed no statistical difference between the 2 groups (P = .98). Postoperative mean Lysholm knee scores were 90 points (range, 78-100) for group I and 85 (range, 70-95) for group II; improvements of 22 and 17 points, respectively. According to the Lysholm knee scores, group I showed slightly better results than did group II, with a statistical significance of P < .01. Telos stress radiography showed the mean difference in posterior translation between the injured and uninjured knees to be 2.2 mm (range, 0 to 7.0 mm) for group I and 2.9 mm (range, 1.0 to 7.0 mm) for group II. The Telos stress test showed no statistical difference between the 2 groups (P = .14).
The clinical outcome was the same for both groups. Despite its comparatively short length and small diameter, the double-loop hamstring tendon autograft was as good as Achilles tendon allograft in PCL reconstruction.

本研究旨在比较在保留原始后交叉韧带（PCL）残端的情况下，使用双股绳肌腱自体移植和跟腱异体移植进行关节镜下PCL重建的临床效果。
治疗结果的病例对照研究。
回顾性分析1997年9月至2000年12月期间仅接受PCL重建的36例患者。其中，18例接受自体双股绳肌腱重建（I组），18例接受跟腱异体移植重建（II组）。两组均采用相同的PCL重建手术。在至少2年的最终随访中，通过4项指标对患者进行评估：国际膝关节文献委员会（IKDC）评估、Lysholm膝关节评分、后抽屉试验和Telos应力放射摄影。
两组术前人口统计学因素（年龄、性别、活动水平和平均手术时间）无统计学显著差异（P>.05）。根据IKDC对I组的评估，18例膝关节中有16例评定为正常或接近正常，2例为异常。按照相同标准，II组18例膝关节中有14例正常至接近正常，3例异常，1例严重异常。IKDC评分在两组间无统计学差异（P =.98）。I组术后平均Lysholm膝关节评分为90分（范围78 - 100），II组为85分（范围70 - 95）；分别改善了22分和17分。根据Lysholm膝关节评分，I组结果略优于II组，具有统计学显著性（P<.01）。Telos应力放射摄影显示，I组患侧与健侧膝关节后移的平均差异为2.2 mm（范围0至7.0 mm），II组为2.9 mm（范围1.0至7.0 mm）。Telos应力试验在两组间无统计学差异（P =.
