摘　　要：目的前瞻性评估保留残端对于前交叉韧带重建临床疗效的意义。方法2008年8月至2009年9月共70例有韧带残端存留的前交叉韧带损伤患者人选本研究组，随机分为保留残端组（n=35）和对照组（n=35）。分别采取关节镜下保留残端重建前交叉韧带和切除残端的前交叉韧带重建手术技术，移植物均使用同种异体肌腱。术后随访分别进行膝关节功能评分（IKDC分级和Lysholm评分）、客观稳定性评估（Lachman试验、轴移试验和KT-1000测量）、本体感觉功能测量和二次关节镜手术探查。结果70例患者中共61例（87％）获得随访，平均随访时间13．1个月。两组的功能评分无显著差异：Lysholm评分：保留残端组96．4分，对照组94．9分（P=0．71）；IKDC分级中A和B级：保留残端组30例，对照组29例（P=0．586）。两组的客观稳定性评估无显著差异：KT-1000测量的侧一侧差值：保留残端组1．69mm，对照组1．65mm（P=0．83）；Lachman试验阴性例数：保留残端组29例，对照组28例（P=1．00）；轴移试验阴性例数：保留残端组31例，对照组27例（P=0．225）。本体感觉的角度重复试验结果无显著差异：保留残端组4．56°，对照组4．28°（P=0．522）。二次手术探查时发现的移植物滑膜覆盖率无显著差异：保留残端组85％，对照组84．2％。结论保留残端同时使用异体肌腱移植重建前交叉韧带，对术后膝关节主观功能评分、稳定性和本体感觉和移植物滑膜覆盖程度并无促进作用。Objective To evaluate the clinical significance of arthroscopic anterior cruciate ligament （ACL） reconstruction using the remnant-preserved technique. Methods From August 2008 to September 2009, 70 cases with the remnant of injured ACL were included in the trials, which were randomized into the remnant preservation （RP） group and the control group, 35 cases in each group. All patients in the two groups underwent arthroscopic ACL reconstruction surgeries, with ACL-remnant preserving technique in RP group and ACL-remnant resection in control group, respectively. The injured ACL was reconstructed with allograft in all cases. Postoperative follow-up assessment included the International Knee Documentation Committee（IKDC） grading and Lyshohn score, Lachman test, pivot shift test and KT-1000 measurement, proprioception measurements and the arthroscopic second look evaluation. Results Sixty-one （61/70, 87% ） cases were available for an average of 13.1 months follow-up assessment postoperatively. There were no significant differences between the RP and control group in functional outcome as evaluated with Lysholm score （96. 4 vs. 94.9, P =0. 71） and IKDC grading （cases with A and B gradings ： 30 vs. 29,P =0. 586）. Regarding objective stability, there were no differences between the 2 group in mean side-to-side difference of KT-1000（ 1.69 mm vs. 1.65 mm, P =0. 83）, Lachman test （ negative cases： 29 vs. 28, P = 1.00） and pivot shift test （negative cases： 31 vs. 27, P =0. 225）. There was also no difference between the groups in proprioception evaluation measured with angle repetitive test （4. 56°vs. 4. 28 °, P = 0. 522）. During second look arthroscopic examination, the grafts synoveal coverage rates were found to be 85% in the RP group and 84. 2% in the control group, without significant difference （ P 〉 0. 05 ）. Conclusions Arthroscopic ACLreconstruction with the remnant preserving technique using tendon allograft do not improve the postoperative knee-joint function sco
