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.
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.
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.
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.
评估滑雪板几何数据和站立高度比对于男女休闲滑雪者前交叉韧带（ACL）损伤风险的影响。
在连续六个冬季赛季中，对ACL损伤和未损伤的休闲滑雪者进行了一项基于问卷的回顾性病例对照研究。记录了每位参与者滑雪板的几何数据（滑雪板长度、侧切半径、板头、板腰和板尾宽度）。使用数字游标卡尺测量滑雪板固定器前后部分的站立高度，并计算前后站立高度比。
共有1817名休闲滑雪者参与了本研究，其中392人（21.6%）发生了ACL损伤。多元逻辑回归分析表明，年龄较大、技能水平较低和行为风险较高是与ACL损伤相关的独立个体风险因素。滑雪板长度增加、板头宽度增加、滑雪板固定器后部的站立高度增加以及站立高度比增加被发现是与ACL损伤相关的独立设备相关风险因素。
较短的滑雪板长度、较窄的板头宽度、较低的后部站立高度和较低的站立高度比（即滑雪板固定器的后部相对于前部更高）与降低ACL损伤的可能性相关。在购买或租赁滑雪板时，可以考虑这些参数以降低休闲滑雪者ACL损伤的可能性。
