Oral contraceptive use and menstrual cycle phase are suggested to influence the risk of anterior cruciate ligament (ACL) injuries in female athletes. However, only few data are available for recreational sports. Therefore, female recreational skiers with a non-contact ACL injury and age-matched controls completed a self-reported questionnaire relating to menstrual history, oral contraceptive use and previous knee injuries. Menstrual history data were used to group subjects into either preovulatory or postovulatory phases of menstrual cycle. Our findings suggest that oral contraceptive use did not show any protective effect against ACL injuries nor did self-reported previous knee injuries show any association with ACL injury rate in recreational alpine skiing. Analysis of menstrual history data revealed that recreational skiers in the preovulatory phase were significantly more likely to sustain an ACL injury than were skiers in the postovulatory phase.
口服避孕药的使用和月经周期阶段被认为会影响女运动员前交叉韧带（ACL）损伤的风险。然而，关于休闲运动的相关数据却很少。因此，患有非接触性ACL损伤的女性休闲滑雪者和年龄匹配的对照组完成了一份关于月经史、口服避孕药使用情况和既往膝关节损伤的自我报告问卷。月经史数据被用于将受试者分为月经周期的排卵前期或排卵后期。我们的研究结果表明，口服避孕药的使用对ACL损伤没有任何保护作用，自我报告的既往膝关节损伤与休闲高山滑雪中的ACL损伤率也没有任何关联。对月经史数据的分析显示，排卵前期的休闲滑雪者比排卵后期的滑雪者更有可能遭受ACL损伤。
