An anterior cruciate ligament (ACL) injury prevention program was evaluated. One hundred and thirteen female high school varsity and junior varsity basketball players and 12 coaches participated in an 8-week educational and skills program. Demographic and injury history data were collected. At pre-intervention and at the end of season, knowledge, attitudes, and practices about ACL risk and injury prevention were assessed via questionnaires, and frequency of two-footed landings were videotaped during games. Univariate statistics described the sample. Paired t-tests evaluated the program's impact. Cronbach's alpha, correlations, and kappa statistics assessed the validity and reliability of questionnaires and video analysis. Of the 113 players, 74 completed the study. The players' mean age was 16.25 years (SD=1.07; range=14.2-18.8). Baseline knowledge score was 57.2%, practice 58.4%, and attitude 73.5%. The mean baseline knowledge score of the 12 coaches (mean age=40.8 years; SD=10.3; range=26.9-56.3) was 68.7%. Players' knowledge about ACL injury prevention improved (t=2.57; P<0.01). No changes in attitudes toward injury prevention were found (t(diff)=1.88; P<0.06). Inter-rater reliability of two-footed landings observed was acceptable (kappa=0.72). Videotape analyses revealed a 5.5% increase in landing performance (t(diff)=9.6; P<0.0001). The program increased knowledge about ACL injury risk and improved player's landing skills.
一项前交叉韧带（ACL）损伤预防计划进行了评估。113 名女性高中校队和初中队篮球运动员和 12 名教练参加了为期 8 周的教育和技能计划。收集了人口统计学和受伤史数据。在干预前和赛季末，通过问卷调查评估了 ACL 风险和损伤预防的知识、态度和实践，在比赛中通过录像评估双脚着地的频率。单变量统计描述了样本。配对 t 检验评估了该计划的影响。克朗巴赫的阿尔法、相关性和 Kappa 统计评估了问卷和视频分析的有效性和可靠性。在 113 名运动员中，有 74 人完成了研究。运动员的平均年龄为 16.25 岁（SD=1.07；范围 14.2-18.8）。基线知识得分 57.2%，实践 58.4%，态度 73.5%。12 名教练（平均年龄 40.8 岁；SD=10.3；范围 26.9-56.3）的基线知识平均得分为 68.7%。运动员对 ACL 损伤预防的知识有所提高（t=2.57；P<0.01）。对预防损伤的态度没有变化（t(diff)=1.88；P<0.06）。观察到的双脚着地的评分者间可靠性是可以接受的（kappa=0.72）。录像分析显示，着陆性能提高了 5.5%（t(diff)=9.6；P<0.0001）。该计划增加了对 ACL 损伤风险的认识，并提高了运动员的着陆技能。
