Accurate documentation of injury incidence is critical for study of injury risk factors and prevention. Comparisons of published incidences of anterior cruciate ligament (ACL) injuries and surgical reconstructions are difficult, however, because of the variations in units. Some studies report absolute time-based denominators (such as annual incidence or incidence per 100,000 person years), whereas others report exposure-based denominators (such as incidence per 1,000 player hours or athlete exposures). We converted exposure-based units into annual incidences to compare various studies. National population studies show annual incidence rates of up to 0.05% per person per year in Australia. Professional athletes in basketball, soccer, and the other football codes report an annual incidence of 0.15%-3.7% in studies with at least a moderate sample size. Annual ACL incidence in amateur sporting groups was generally higher than the entire population but lower than among professional athletes. Converting incidence rates to annual units allowed better comparisons to be made between population rates across different studies.
准确记录损伤发生率对于研究损伤危险因素和预防至关重要。然而，由于单位的差异，比较已发表的前交叉韧带（ACL）损伤和手术重建的发生率存在困难。一些研究报告基于绝对时间的分母（如每年的发生率或每 10 万人年的发生率），而另一些研究报告基于暴露的分母（如每 1000 名球员小时或运动员暴露的发生率）。我们将基于暴露的单位转换为年度发生率，以比较各种研究。澳大利亚的全国人群研究显示，每年每个人的发生率高达 0.05%。在至少具有中等样本量的研究中，篮球、足球和其他橄榄球项目的职业运动员的年发生率为 0.15%-3.7%。业余运动群体的 ACL 年发生率通常高于整个人群，但低于职业运动员。将发生率转换为年度单位，使得在不同研究之间进行人群率的比较变得更加容易。
