术后MRI移植物成熟度：单纯ACL重建与前外侧加强ACL重建的系统评价和Meta分析
简介
这项系统综述与荟萃分析纳入5项研究共450例患者，采用MRI信号噪声比（SNQ）评估移植物成熟度，比较前交叉韧带重建（ACLR）联合前外侧加强术（肌腱固定或前外侧韧带重建）与单纯ACLR的差异。结果显示，两组移植物成熟度未见显著差异（MD -0.77，95% CI -3.56~2.03，p=0.59），但异质性较高（I²=92%）。摘要同时指出，部分研究报告…
英文摘要
OBJECTIVES: This study aims to evaluate whether the association of an anterolateral extra-articular procedure (tenodesis or anterolateral ligament reconstruction) to anterior cruciate ligament reconstruction (ACLR) correlates with graft maturation time. METHODS: We systematically searched PubMed, Embase, and the Cochrane Central for studies comparing the graft maturation time between ACLR with anterolateral augmentation (ALA) and isolated ACLR. We assessed graft maturation, via Magnetic Resonance Imaging (MRI) using the signal-to-noise quotient (SNQ). Statistical analyses were performed using Review Manager 5.4. Odds ratios (OR) and mean differences (MD) with 95% confidence intervals (CIs) were pooled using random-effects models based on heterogeneity (I2). RESULTS: Five studies, including 450 patients, assessed graft maturation using SNQ values. No significant difference was observed between ACLR combined with ALA and isolated ACLR (MD -0.77; 95% CI -3.56-2.03; p=0.59; I2=92%), with substantial heterogeneity. CONCLUSIONS: The addition of ALA to ACLR does not appear to significantly enhance graft maturation. While some studies report improved stability, these benefits do not consistently translate into better ligamentization. The decision to augment ACLR should be individualized, considering population and individual characteristics. Level of Evidence III; Systematic Review.
