Abstract：
OBJECTIVE: To determine whether femoral tunnel length (FTL) affects clinical or functional outcomes following primary Anterior cruciate ligament reconstruction (ACLR) with single-bundle quadriceps tendon autograft, both with and without a patellar bone block.
METHODS: An electronic search of MEDLINE, EMBASE, and Cochrane databases was carried out via OVID. Data pertaining to study characteristics, patient demographics, surgical techniques, femoral tunnel length, and subjective/objective clinical outcomes was abstracted. Studies were stratified into two groups based on FTL; a short femoral tunnel (S-FT) group of ≤25 mm, and a long femoral tunnel (L-FT) group of >25 mm. There was a high degree of heterogeneity between studies, prohibiting meta-analysis.
RESULTS: Seven studies comprising 368 total patients with a mean age of 30.3 years (range: 23.4-34 years) were included for analysis. The S-FT group included 126 patients and the L-FT group 242 patients. Both groups demonstrated statistically significant postoperative improvements across both subjective and objective clinical and functional outcomes. Average complication rates were 11.9% (range: 0%-29%) in the S-FT group and 4.5% (range: 1%-14%) in the L-FT group. Ranges of re-rupture rates were 0%-2% and 0%-3% for the S-FT and L-FT groups, respectively (n.s.).
CONCLUSIONS: Both S-FT and L-FT groups demonstrated comparable postoperative outcomes following primary ACLR with single bundle quadriceps tendon autograft. There were slightly superior, although non-significant, outcomes reported with short femoral tunnel length, however, this may have been confounded by the variation in surgical technique used.
METHODS: IV.

摘要：
目的：为了确定股骨隧道长度（FTL）是否影响原发性前交叉韧带重建（ACLR）与单束股四头肌腱自体移植后的临床或功能结果，有和没有髌骨块。
方法：MEDLINE的电子搜索，EMBASE,Cochrane数据库是通过OVID进行的。与研究特征有关的数据，患者人口统计学，外科技术,股骨隧道长度,并提取主观/客观临床结果。根据FTL将研究分为两组；短股骨隧道（S-FT）组≤25mm，和>25mm的长股骨隧道(L-FT)组。研究之间存在高度异质性，禁止荟萃分析。
结果：包括368名平均年龄为30.3岁（范围：23.4-34岁）的患者的7项研究被纳入分析。S-FT组包括126例患者,L-FT组包括242例患者。两组在主观和客观临床和功能结果方面均显示出统计学上显着的术后改善。S-FT组的平均并发症发生率为11.9%（范围：0%-29%），L-FT组为4.5%（范围：1%-14%）。S-FT组和L-FT组的再破裂率范围分别为0%-2%和0%-3%,分别（n.s.）。
结论：S-FT组和L-FT组在采用单束股四头肌腱自体移植的原发性ACLR术后结果相当。有稍微优越的，虽然不重要，结果报告与短股骨隧道长度，然而,这可能与所用手术技术的变化有关.
