to evaluate if ACL injuries are associated with recreational skiers using rented skis and whether individual factors, ski geometry parameters and standing heights differ between skiers who rented or owned skis. A retrospective questionnaire-based, case-control study of ACL-injured and uninjured recreational skiers was conducted during six winter seasons. Age, sex, body height, body weight, nationality, ownership of skis, skill level, risk-taking behavior, ski length, side-cut radius, widths of the tip, waist, and tail, and the standing heights at the front and rear components of the ski binding were assessed. Additionally, ratios between ski widths and a standing height ratio were calculated. Altogether, 1780 skiers (48.9% females) with a mean age of 39.2 ± 13.0 years participated, of whom 22.0% sustained an ACL injury and 32.3% rented skis. ACL injury risk was significantly associated with rented skis (OR 3.2, 95% CI 2.5-4.0). Compared to skiers using own skis, participants who rented skis were more likely female, smaller and lighter, tourists, less skilled and more cautious. In comparison to owned skis, rented skis showed significantly lower mean values in ski length, side-cut radius, ski widths, and for the three ski widths ratios. Additionally, standing heights were significantly lower while standing height ratio was higher for rented skis. Beside individual factors, equipment-related factors should be considered when renting skis in order to reduce ACL injury risk.
评估使用租赁雪板的竞技滑雪者中 ACL 损伤的情况，以及个体因素、滑雪几何参数和站立高度是否在租赁和自有雪板的滑雪者之间存在差异。在六个冬季赛季期间，进行了一项基于回顾性问卷调查的 ACL 损伤和未损伤竞技滑雪者的病例对照研究。评估的因素包括年龄、性别、身高、体重、国籍、雪板所有权、滑雪技能水平、冒险行为、雪板长度、侧切半径、板头、板腰和板尾的宽度，以及滑雪板绑定前、后组件的站立高度。此外，还计算了滑雪板宽度与站立高度的比值。共有 1780 名滑雪者（48.9%为女性）参与了研究，平均年龄为 39.2±13.0 岁，其中 22.0%发生 ACL 损伤，32.3%租赁雪板。ACL 损伤风险与租赁雪板显著相关（OR 3.2，95%CI 2.5-4.0）。与使用自有雪板的滑雪者相比，租赁雪板的滑雪者更有可能为女性、身材更小、体重更轻、为游客、技能水平更低、更谨慎。与自有雪板相比，租赁雪板的雪板长度、侧切半径、雪板宽度以及三个雪板宽度比值的平均值明显更低。此外，租赁雪板的站立高度明显更低，而站立高度比值更高。除了个体因素，在租赁雪板时还应考虑与设备相关的因素，以降低 ACL 损伤的风险。
