前交叉韧带（ACL）重建是美国每年最常见的运动医学手术之一。据报道，国家优秀运动员中男女ACL撕裂的发生率（IR）存在差异。然而，在已发表的文献中，很少有信息专门评估在健康维护组织（HMO）环境中进行ACL重建的IR。不同人群的ACL重建IR可能存在差异。
目的
本研究报告了ACL重建术在预定人群中的IR，并比较了年龄和性别随时间的差异。
设计
通过查询管理数据库，对2001年至2005年在南加州Kaiser Permanente进行的4485例ACL重建进行了回顾性分析。计算每10万名成员的IR趋势，并在年龄，性别和五年研究期间进行比较。
主要观察指标
采用线性回归检验IR趋势，采用χ（2）检验比较性别分布。方差分析用于比较男性和女性的平均年龄。使用独立样本t检验比较每个独立年份男性和女性的平均年龄。
结果
女性ACL重建的IR从2001年的14.4（95%置信区间[CI]，12.6-16.3）显著上升（p = 0.010）至2005年的19.3（95% CI，17.2-21.5）。在特定年龄组中，14至17岁（p = 0.013）、18至21岁（p = 0.017）和45至49岁（p = 0.014）的女性IR显着增加。变化最大的是14至17岁的女性年龄组，以每年每100 000人8.14例的速度增长。
结论
确定ACL重建率增长最快的性别和年龄组在实施ACL损伤预防计划中非常重要。
CONTEXT
Anterior cruciate ligament (ACL) reconstructions are among the most common sports medicine procedures performed in the US each year. Differences have been reported in the incidence rates (IRs) of ACL tears among male and female national elite athletes. However, there is little information in the published literature that assesses IRs for ACL reconstructions done in the Health Maintenance Organization (HMO) setting specifically. Different populations may show variation in ACL reconstruction IRs.
OBJECTIVE
This study reports on the IR of ACL reconstructions in a predefined population and compares the differences in age and sex over time.
DESIGN
A retrospective analysis of 4485 ACL reconstructions performed within Kaiser Permanente Southern California between 2001 and 2005 was completed by a query of an administrative database. Trends in IRs per 100,000 members were calculated and compared across age, sex, and the five-year study period.
MAIN OUTCOME MEASURES
Linear regression was used to test trends in IR. Sex distribution was compared using the χ(2) test. Analysis of variance was used to compare the mean age from year to year in males and females. The independent sample t-test was used to compare mean age between males and females for each independent year.
RESULTS
The IR of ACL reconstructions in females rose significantly (p = 0.010) from 14.4 in 2001 (95% confidence interval [CI], 12.6-16.3) to 19.3 in 2005 (95% CI, 17.2-21.5). Within specific age groups, IR increased significantly for females age 14 to 17 (p = 0.013), 18 to 21 (p = 0.017), and 45 to 49 years (p = 0.014). The most dramatic change was seen in the female age category of 14 to 17 years, which increased at a rate of 8.14 cases/100,000 members per year.
CONCLUSION
Identifying the sex and age groups with most rapidly increasing rates of ACL reconstructions is important in implementing ACL injury-prevention programs.
