Objectives To evaluate the impact of ski geometry data and standing height ratio on anterior cruciate ligament (ACL) injury risk of male and female recreational skiers. Methods A retrospective questionnaire-based, case–control study of ACL-injured and uninjured recreational skiers was conducted during six consecutive winter seasons. Ski geometry data (ski length, side-cut radius, widths of the tip, waist and tail) were recorded from each participant’s skis. Standing heights at the front and rear components of the ski binding were measured with a digital sliding calliper, and the standing height ratio between the front and rear was calculated. Results A total of 1817 recreational skiers participated in this study, of whom 392 (21.6%) sustained an ACL injury. Multiple logistic regression analysis indicates a higher age, a lower skill level and riskier behaviour as independent individual risk factors associated with an ACL injury. An increase in ski length, tip width of the ski, standing height at the rear ski binding component, and in standing height ratio were found to be independent equipment-related risk factors for an ACL injury. Conclusion Reduced ski length, narrower ski tip width, lower rear standing height and a lower standing height ratio (ie, rear component of the ski binding is more elevated compared with the front component) were associated with a reduced likelihood for ACL injury. When buying or renting skis, these parameters could be considered to reduce the likelihood of ACL injury in recreational skiers. Data are available on reasonable request.

滑雪几何数据和站立高度比对 ACL 损伤风险的影响及其在休闲滑雪者预防中的应用


目的 评估滑雪几何数据和站立身高比对男性和女性休闲滑雪者前十字韧带 (ACL) 损伤风险的影响。方法 在连续六个冬季对 ACL 受伤和未受伤的休闲滑雪者进行了一项基于问卷调查的回顾性病例对照研究。记录每个参与者滑雪板的滑雪几何数据（滑雪板长度、侧切半径、尖端宽度、腰部和尾部）。用数显游标卡尺测量滑雪固定器前后部件的站立高度，并计算前后的站立高度比。结果 共有 1817 名休闲滑雪者参与本研究，其中 392 名（21.6%）患有 ACL 损伤。多元逻辑回归分析表明，较高的年龄、较低的技能水平和较高的风险行为是与 ACL 损伤相关的独立个体危险因素。研究发现，滑雪板长度、滑雪板尖端宽度、滑雪板后固定装置的站立高度以及站立高度比的增加是导致 ACL 损伤的独立设备相关风险因素。结论 缩短滑雪板长度、缩小滑雪板尖端宽度、降低后站立高度和降低站立高度比（即，滑雪板固定装置的后部组件比前部组件更高）与 ACL 损伤的可能性降低相关。在购买或租赁滑雪板时，可以考虑这些参数来降低休闲滑雪者 ACL 受伤的可能性。可根据合理要求提供数据。
