“…Prior studies have examined the relationship of patient age, sex, and height with ACL morphology, finding ACLs to generally increase in length and cross‐sectional area, and to become more vertical in the sagittal and coronal planes as patients age [7, 8]. While ACL growth occurs during a predictable age range, the specific ACL length and cross‐sectional area are significantly different between males and females with increasing patient height [13, 15]. Given the reports of differences in ligamentous morphology based on demographic characteristics, it is imperative to further explore all patient factors contributing to ligamentous variability.…”

Purpose To develop a method for using an intact posterior cruciate ligament (PCL) as a predictor of anterior cruciate ligament (ACL) graft size and examine possible differences in tunnel length based on all-epiphyseal drilling method. Methods One hundred one patients 5–18 years of age with magnetic resonance imaging (MRI) of the knee at an outpatient pediatric orthopaedic clinic from 2008 to 2020 were included. ACL and PCL coronal, sagittal, and length measurements were made in all patients. Tunnel length measurements were made in patients with open physes. Statistical analyses were performed to evaluate potential associations in patient bony or ligamentous measurements. Results PCL sagittal width and PCL coronal width were statistically significant predictors of ACL sagittal width and ACL coronal width, respectively (p = 0.002, R = 0.304; p = 0.008, R = 0.264). The following equations were developed to calculate ACL coronal and sagittal width measurements from the corresponding measurement on an intact PCL; ACL Coronal Width (mm) = 6.23 + (0.16 x PCL Coronal Width); ACL Sagittal Width (mm) = 5.85 + (0.53 x PCL Sagittal Width). Mean tibial maximum oblique length (27.8 mm) was longer than mean tibial physeal sparing length (24.9 mm). Mean femoral maximum oblique length (36.9 mm) was comparable to mean femoral physeal sparing length (36.1 mm). Both were longer than mean femoral straight lateral length (32.7 mm). Conclusion An intact PCL is a predictor of native ACL size. Tunnel length differs based on chosen drilling method in all-epiphyseal technique. Level of evidence Diagnostic Level III.

“…Le diamètre correspond dans notre étude à une largeur de la greffe. Tomaszweski , 2020 a démontré chez 132 patients âgés de 14.9 ans en moyenne [8 ; 18] que le diamètre dans sa portion intra-articulaire évolue de façon linéaire entre 8 et 18 ans (26). Putur, 2020 a réalisé une analyse selon l'âge de 162 genoux chez 147 enfants entre 0 et 18 ans et a pu mettre en évidence que la croissance du LCA était de 0.45 mm/an entre 1.5 et 14.5 ans et qu'elle devient quasi nulle après 14.5 ans jusqu'à l'âge adulte.…”

“…The question remains whether these outcomes are applicable in adolescents, as adolescence is a period of growth, development and maturation. To this date, one study evaluated the predictability of hamstring tendon dimensions in children and adolescents based on magnetic resonance imaging (MRI) measurements [ 15 ]. Other studies evaluated the relationship of anthropometric values or MRI measurements with the diameter of a hamstring tendon autograft for a specific ACL reconstruction technique, but did not analyse the length of the hamstring tendons itself [ 16 – 19 ].…”

Background 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. Methods 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. Results 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. Conclusions 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. Level of evidence 3
