Hamstring tendon graft diameter less than 8 mm has been correlated with an increased risk of anterior cruciate ligament reconstruction (ACLR) graft failure. The purpose of this study was to measure and compare the diameter of 3-, 4-, 5-, and 6-strand gracilis and semitendinosus (ST) hamstring tendon (HT) ACLR grafts, and to determine if there is a correlation between anthropometric data, HT length, and diameter of the HT ACLR graft.
Male patients (n = 78) undergoing primary or revision ACLR with a HT autograft between July 2018 and March 2020 were recruited. Pre-operative anthropometric data was collected. Gracilis and ST tendons were harvested and the length and diameter measured. The following HT graft configurations were prepared in each patient: triple ST; double gracilis + double ST; double gracilis + triple ST; triple gracilis + triple ST. Paired t-tests and Pearson's correlation coefficients were used to assess demographics, anthropometrics, graft diameter, and tendon length. A non-parametric test was used to compare femoral and tibial ACL graft diameters of the 3-, 4-, 5-, and 6-strand HT graft configurations.
For the femoral end, 10%, 19%, 69% and 86% of the patients achieved graft diameters of equal to or greater than 8 mm in 3-, 4-, 5- and 6-strand HT graft configurations respectively. For the tibial end, 27%, 10%, 83%, and 92% of the patients achieved graft diameters of equal to or greater than 8 mm in 3-, 4-, 5-, and 6-strand HT graft configurations respectively. The largest increases in HT graft diameters were noted between the femoral end of 6- vs. 3-strand grafts (mean difference 1.7 ± 0.5 mm; p < 0.001) and between the tibial end of 6- vs. 4-strand grafts (mean difference 2.0 ± 0.5 mm; p < 0.001). Height and leg length were moderately positively correlated with ST tendon length (r = 0.54-0.51) and gracilis tendon length (r = 0.52-0.45), and thigh and shank lengths were moderately positively correlated with ST tendon length (r = 0.43 and 0.40, respectively).
Traditional 4-strand HT ACL autografts in male patients undergoing ACLR in the United Arab Emirates result in graft diameters less than 8 mm in the majority of patients.

腘绳肌腱移植物直径小于 8 毫米与前交叉韧带重建 (ACLR) 移植物失败的风险增加有关。本研究的目的是测量和比较 3 股、4 股、5 股和 6 股股薄肌和半腱肌 (ST) 腘绳肌腱 (HT) ACLR 移植物的直径,并确定人体测量数据、HT 长度和 HT ACLR 移植物直径之间是否存在相关性。
招募了 2018 年 7 月至 2020 年 3 月期间接受 HT 自体移植物进行原发性或复发性 ACLR 的男性患者 (n=78)。收集术前人体测量数据。采集股薄肌和半腱肌腱,并测量长度和直径。在每位患者中制备以下 HT 移植物构型:三联 ST;双股薄肌+双股 ST;双股薄肌+三联 ST;三联股薄肌+三联 ST。使用配对 t 检验和 Pearson 相关系数评估人口统计学、人体测量学、移植物直径和肌腱长度。使用非参数检验比较 3 股、4 股、5 股和 6 股 HT 移植物构型的股骨和胫骨 ACL 移植物直径。
对于股骨端,在 3 股、4 股、5 股和 6 股 HT 移植物构型中,分别有 10%、19%、69%和 86%的患者达到了等于或大于 8 毫米的移植物直径。对于胫骨端,在 3 股、4 股、5 股和 6 股 HT 移植物构型中,分别有 27%、10%、83%和 92%的患者达到了等于或大于 8 毫米的移植物直径。在股骨端,6 股与 3 股移植物之间(平均差异 1.7±0.5 毫米;p<0.001)和胫骨端 6 股与 4 股移植物之间(平均差异 2.0±0.5 毫米;p<0.001)观察到 HT 移植物直径的最大增加。身高和腿长与 ST 肌腱长度(r=0.54-0.51)和股薄肌肌腱长度(r=0.52-0.45)呈中度正相关,大腿和小腿长度与 ST 肌腱长度呈中度正相关(r=0.43 和 0.40)。
在阿拉伯联合酋长国接受 ACLR 的男性患者中,传统的 4 股 HT ACL 自体移植物导致大多数患者的移植物直径小于 8 毫米。
