Abstract：
OBJECTIVE: To evaluate the utility of semitendinosus tendon (ST) and gracilis tendon (GT) cross-sectional area (CSA) on magnetic resonance imaging (MRI) and anthropometric characteristics in preoperative estimation of graft diameter in patients undergoing anterior cruciate ligament reconstruction (ACLR) with four-strand hamstring autografts.
METHODS: Three databases were searched on 29 August 2023. The authors adhered to the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) and R-AMSTAR (Revised Assessment of Multiple Systematic Review) guidelines and the Cochrane Handbook for Systematic Reviews of Interventions. Data on demographics, anthropometric characteristics, imaging techniques, tendon CSA, correlation coefficients, sensitivities, specificities, regression models and cutoffs for predicting intraoperative graft diameters above 8 mm were recorded.
RESULTS: Forty-six studies comprising 4140 patients were included. Twelve of 19 (63.2%) studies reporting on ST + GT CSA found a moderate to very high correlation with intraoperative graft diameter. Five of 10 (50%) and one of seven (14.3%) studies reporting on ST CSA and GT CSA, respectively, found a moderate to high correlation with intraoperative graft diameter. Cutoffs of ST + GT CSA for predicting graft diameters above 8 mm ranged from 15.8 to 31.2 mm2. Nine of 35 (25.7%) studies that reported on height found a moderate to very high correlation with graft diameter. Seven of 33 (21.2%) studies reporting on weight found a moderate correlation with graft diameter.
CONCLUSIONS: Of the MRI parameters assessed, ST + GT CSA was the most reliable predictor of graft diameter. However, cutoffs, sensitivities, and specificities for predicting diameters above 8 mm were highly variable. Anthropometric characteristics in general were less predictive of graft diameter than MRI parameters. This information can be used by clinicians to predict patients at risk for ACLR failure due to insufficient graft size.
METHODS: Level IV.

摘要：
目的：评估半腱肌腱（ST）和股薄肌腱（GT）横截面积（CSA）在磁共振成像（MRI）和人体测量特征在术前估计移植物直径中的应用。
方法：于2023年8月29日检索了三个数据库。作者坚持PRISMA（系统审查和荟萃分析的首选报告项目）和R-AMSTAR（修订的多重系统审查评估）指南以及Cochrane干预措施系统审查手册。人口统计数据，人体测量特征,成像技术，肌腱CSA,相关系数，敏感性，特殊性，记录预测术中移植物直径大于8mm的回归模型和截止值.
结果：纳入46项研究，包括4140名患者。报告ST+GTCSA的19项研究中有12项(63.2%)发现与术中移植物直径有中等至非常高的相关性。报告STCSA和GTCSA的10项研究中的5项（50％）和7项研究中的一项（14.3％），分别,发现与术中移植物直径有中度到高度相关性。STGTCSA用于预测8mm以上的移植物直径的临界值为15.8至31.2mm2。据报道，身高的35项研究中有9项（25.7％）与移植物直径有中等至非常高的相关性。报告体重的33项研究中有7项（21.2％）发现与移植物直径中等相关。
结论：在评估的MRI参数中，ST+GTCSA是移植物直径最可靠的预测因子。然而,关口,敏感性，预测8毫米以上直径的特异性差异很大。与MRI参数相比，人体测量特征对移植物直径的预测较少。临床医生可以使用此信息来预测由于移植物尺寸不足而面临ACLR失败风险的患者。
方法：四级。
