UNASSIGNED:
UNASSIGNED: To determine risk factors for second anterior cruciate ligament (ACL) injury following primary ACL reconstruction (ACLR) using return-to-sport (RTS) tests consisting of qualitative and quantitative measures in young athletes.
UNASSIGNED: A case-control study design was used, and a retrospective review of adolescent athletes after primary ACLR was performed. All athletes completed an RTS test consisting of qualitative and quantitative assessments and psychological assessments with the Tampa Scale of Kinesiophobia. Athlete demographics, surgical characteristics and sports participation were also examined. A binary logistic regression was performed to verify an independent association between risk factors and second ACL injury using adjusted OR (aORs), 95% CI and p<0.05.
UNASSIGNED: In 72 eligible athletes, 12 (16.7%) suffered a second ACL injury. The mean Tegner activity level was 8.4+1.1, and the mean time from ACLR to RTS test completion was 10.4+2.9 months. One variable that showed the lowest p-value in the preliminary analysis was entered into the binary logistic regression model, which resulted in that qualitative assessment of knee valgus during the sidestep cut was associated with second ACL injury (aOR=4.64, 95% CI: 1.18 to 18.23, p=0.03).
UNASSIGNED: Athletes who demonstrated excessive dynamic knee valgus on the involved limb during the sidestep cut were approximately 4.6 times more likely to suffer a second ACL injury.

摘要：
■
■使用由年轻运动员的定性和定量措施组成的回归运动（RTS）测试，确定初次ACL重建（ACLR）后第二前交叉韧带（ACL）损伤的危险因素。
■采用病例对照研究设计，并对初级ACLR后的青少年运动员进行了回顾性审查。所有运动员都完成了RTS测试，包括使用坦帕恐惧症量表进行的定性和定量评估以及心理评估。运动员人口统计，还检查了手术特征和运动参与。使用校正OR（aOR）进行二元逻辑回归以验证危险因素与第二ACL损伤之间的独立关联。95%CI和p<0.05。
■在72名符合条件的运动员中，12（16.7％）遭受了第二次ACL损伤。平均Tegner活性水平为8.4+1.1，从ACLR到RTS测试完成的平均时间为10.4+2.9个月。在初步分析中显示最低p值的一个变量被输入二元逻辑回归模型，这导致侧切术期间膝关节外翻的定性评估与第二次ACL损伤相关(aOR=4.64,95%CI:1.18~18.23,p=0.03)。
■在切边过程中在患肢上表现出过度动态膝关节外翻的运动员遭受第二次ACL损伤的可能性约为4.6倍。
