During puberty, the biological maturity of children of the same chronological age differs. To generate equal opportunities for talent selection in youth sports, the athlete's biological maturity should be considered. This is often assessed with a left hand and wrist radiography. Alternatively, ultrasound (US) could be advantageous, especially by avoiding ionizing radiation. This pilot study aimed to assess intrarater and interrater reliability of an experienced and a non-experienced examiner in an US-based examination of the knee in 20 healthy females (10-17 years). Epiphyseal closure at five anatomical landmarks was staged (stages 1-3) and its interrater and intrarater reliabilities were analyzed using Cohen's kappa (). Interrater reliability of the calculation of the ossification ratio (OssR) was analyzed using the Bland-Altman method and intraclass correlation coefficients (ICCs). Interrater reliability for the stages was almost perfect for four landmarks. Interrater reliability ranged from = 0.69 to = 0.90. Intrarater reliability for the stages was almost perfect for four landmarks. Intrarater reliability ranged from = 0.70 to = 1.0. For the OssR, ICC was 0.930 and a minimal detectable change of 0.030 was determined. To conclude, experienced and non-experienced examiners can reliably assign individuals to different ossification stages and calculate an OssR using US-based imaging of the knee.
在青春期，相同实足年龄的儿童生理成熟度存在差异。为了在青少年体育中创造平等的人才选拔机会，应考虑运动员的生理成熟度。这通常通过左手和手腕X光摄影来评估。另外，超声（US）可能具有优势，特别是可以避免电离辐射。这项初步研究旨在评估一名经验丰富的检查者和一名经验不足的检查者在对20名健康女性（10 - 17岁）进行基于超声的膝关节检查时的评分者内和评分者间信度。对五个解剖标志点的骨骺闭合情况进行分期（1 - 3期），并使用科恩kappa系数（）分析其评分者间和评分者内信度。使用布兰德 - 奥特曼方法和组内相关系数（ICC）分析骨化率（OssR）计算的评分者间信度。四个标志点的分期评分者间信度几乎完美。评分者间信度范围为 = 0.69至 = 0.90。四个标志点的分期评分者内信度几乎完美。评分者内信度范围为 = 0.70至 = 1.0。对于OssR，ICC为0.930，确定最小可检测变化为0.030。总之，经验丰富和经验不足的检查者都可以可靠地将个体分配到不同的骨化阶段，并使用基于超声的膝关节成像计算OssR。
