Knowing the potential hamstring tendon length is relevant for planning ligament reconstructions in children and adolescents, as it is not uncommon to encounter small hamstring tendons intraoperatively. The aim of this study is to predict semitendinosus and gracilis tendon length based on anthropometric values in children and adolescents. The secondary aim is to analyse hamstring tendon autograft characteristics in a closed socket anterior cruciate ligament reconstructions and to evaluate the relationship with anthropometric variables. The hypothesis of this study was that height is predictor of hamstring tendon length and thereby graft characteristics.
This observational study included two cohorts of adolescents undergoing ligament reconstructions between 2007-2014 and 2017-2020. Age, sex, height and weight were recorded preoperatively. Semitendinosus and gracilis tendon length and graft characteristics were measured intraoperatively. Regression analysis was performed on tendon length and anthropometric values. Subgroup analyses of the closed socket ACL reconstruction were performed and the relation between anthropometric values and graft characteristics were analysed.
The population consisted of 171 adolescents from 13 to 17 years of age, with a median age of 16 years [IQR 16-17]. The median semitendinosus tendon length was 29 cm [IQR 26-30] and gracilis tendon length was 27 cm [IQR 25-29]. Height was a significant predictor of semitendinosus and gracilis tendon length. Subgroup analysis of the closed socket ACL reconstructions showed that in 75% of the procedure, the semitendinosus tendon alone was sufficient to create a graft with a minimum diameter of 8.0 mm.
Height is a significant predictor of semitendinosus and gracilis tendon length in adolescents between 13 and 17 years of age and outcomes are similar to data in adults. In 75% of the closed socket ACL reconstructions, the semitendinosus tendon alone is sufficient to create an adequate graft with a minimum diameter of 8 mm. Additional use of the gracilis tendon is more often necessary in females and shorter patients.
了解潜在的腘绳肌腱长度对于规划儿童和青少年的韧带重建至关重要，因为术中经常会遇到较小的腘绳肌腱。本研究的目的是基于儿童和青少年的人体测量值预测半腱肌和股薄肌肌腱的长度。次要目的是分析在闭合套管前交叉韧带重建中腘绳肌腱移植物的特征，并评估与人体测量变量的关系。本研究的假设是身高是预测腘绳肌腱长度和移植物特征的指标。
本观察性研究包括 2007-2014 年和 2017-2020 年期间接受韧带重建的两组青少年患者。术前记录年龄、性别、身高和体重。术中测量半腱肌和股薄肌肌腱的长度和移植物特征。对肌腱长度和人体测量值进行回归分析。对闭合套管 ACL 重建进行亚组分析，并分析人体测量值与移植物特征之间的关系。
该人群由 13 至 17 岁的 171 名青少年组成，中位年龄为 16 岁[IQR 16-17]。半腱肌肌腱长度的中位数为 29cm[IQR 26-30]，股薄肌肌腱长度的中位数为 27cm[IQR 25-29]。身高是半腱肌和股薄肌肌腱长度的显著预测指标。闭合套管 ACL 重建的亚组分析显示，在 75%的手术中，单独使用半腱肌肌腱即可创建最小直径为 8.0mm 的移植物。
身高是 13 至 17 岁青少年半腱肌和股薄肌肌腱长度的重要预测指标，其结果与成人数据相似。在 75%的闭合套管 ACL 重建中，单独使用半腱肌肌腱即可创建最小直径为 8mm 的足够移植物。在女性和身材较矮小的患者中，更常需要额外使用股薄肌肌腱。
