Abstract：
UNASSIGNED: A disadvantage of using hamstring tendon autograft consisting of the semitendinosus and gracilis tendons for anterior cruciate ligament reconstruction is pain from tendon harvesting and persistent hamstring weakness. In the tendon-sparing all-inside technique, a quadrupled semitendinosus graft and adjustable-loop cortical fixation are suggested to give less postoperative flexion deficits while displaying overall similar clinical results to the traditional hamstring technique. However, there are a limited number of high-quality studies comparing these techniques with inconsistent results.
UNASSIGNED: To investigate differences between the all-inside (quadrupled semitendinosus) and traditional hamstring (double-stranded semitendinosus and gracilis) technique regarding (1) self-reported function, (2) hamstring strength, and (3) knee laxity.
UNASSIGNED: Randomized controlled trial; Level of evidence, 1.
UNASSIGNED: A total of 98 patients were randomized to either the all-inside or the traditional hamstring technique. Perioperatively, duration of surgery and graft size were obtained. The International Knee Documentation Committee 2000 Subjective Knee Form score, Knee injury and Osteoarthritis Outcome Score, Tegner Activity Scale score, knee laxity (KT-1000 arthrometer side-to-side difference and pivot shift), range of motion, isokinetic knee strength, and hop test score were collected preoperatively and 2 years postoperatively. Return-to-sport readiness was evaluated 9 months postoperatively.
UNASSIGNED: A total of 89 patients completed 2-year follow-up, 45 patients with the all-inside technique and 44 patients with the traditional hamstring technique. There were no significant differences between groups in any of the outcome measures 2 years after surgery, but there was a tendency in the all-inside group toward having increased anterior translation (mean, 3.6 mm vs 2.7 mm), a higher number of revision surgeries (5 patients vs 2 patients), and more patients having +1 and +2 pivot-shift values (29 vs 18 patients) when compared with the traditional group.
UNASSIGNED: The all-inside technique yields equivalent results to the traditional hamstring technique 2 years after surgery and should be considered a reliable technique to use for ACL reconstruction. Sparing the gracilis tendon does not lead to less persistent hamstring weakness. Long-term follow-up is needed to further determine whether the tendency of increased anterior translation seen at 2 years postoperatively will lead to a higher risk of graft failure.

摘要：
■使用由半腱肌和股薄肌腱组成的自体绳肌腱移植进行前交叉韧带重建的缺点是肌腱收获引起的疼痛和持续的绳肌无力。在保留肌腱的全内技术中，建议采用4倍半腱肌移植和可调节的皮质环固定术可减少术后屈曲缺陷，同时显示出与传统腿筋技术相似的总体临床结果。然而,有数量有限的高质量研究比较这些技术与不一致的结果.
■为了研究全内（四倍半腱肌）和传统腿筋（双链半腱肌和股薄肌）技术之间的差异，关于（1）自我报告的功能，(2)腿筋力量,和（3）膝盖松弛。
■随机对照试验；证据水平，1.
■总共98名患者被随机分配到全内或传统的腿筋技术。围手术期,获得手术持续时间和移植物大小。国际膝关节文献委员会2000年主观膝关节形式评分，膝关节损伤和骨关节炎结果评分，Tegner活动量表评分,膝关节松弛度（KT-1000关节计左右差和枢轴移位），运动范围,等速膝关节强度，收集术前和术后2年的跳跃测试评分。术后9个月评估恢复运动准备情况。
■共有89名患者完成了2年的随访，45例患者采用全内技术，44例患者采用传统腿筋技术。手术后2年，两组之间的任何结果指标均无显着差异，但是在全内组中有一种趋势是前平移增加(平均，3.6毫米vs2.7毫米），修正手术数量较高（5例vs2例），与传统组相比，更多的患者具有+1和+2枢轴移位值(29例vs18例)。
■全内技术在手术后2年产生与传统的腿筋技术相当的结果，应被视为用于ACL重建的可靠技术。保留股薄肌腱不会导致不太持久的腿筋无力。需要长期随访，以进一步确定术后2年出现的前平移增加的趋势是否会导致更高的移植失败风险。
