Abstract

A systematic search was performed of online databases for any anterior cruciate ligament (ACL) injuries within the NBA. Video was obtained of injuries occurring during competition and downloaded for 2-dimensional video analysis. Thirty-five in-game videos were obtained for analysis. Of the reviewed cases, 19% were noncontact ACL injuries where there was no player-to-player contact from an opposing player. Three injury mechanism categories were found based on the events at the point of initial ground contact of the foot of the injured limb: single-leg casting (mean dorsiflexion angle 18.9° (14.4°); mean knee flexion angle 15.6° (7.8°); and mean trunk lateral flexion 18.2° (8.4°)); bilateral hop (mean dorsiflexion angle 18.2° (15.2°), mean knee flexion angle 21° (14.5°), mean trunk extension angle 6.9° (11.4°), and landing angle from the athlete's center of mass 47.9° (10.1°)); and single-leg landing after contact (mean abduction angle of the swing leg 105.4° (18.1°), mean knee flexion angle of the injured limb 34.2° (8.0°), and mean trunk ipsilateral flexion angle 22.2° (7.0°)).

职业篮球运动员前十字韧带撕裂机制:视频分析。

一个系统的搜索进行了在线数据库的任何前交叉韧带(ACL)损伤在NBA。获取比赛中受伤的视频，下载进行二维视频分析。获得35个游戏内视频进行分析。在回顾的案例中，19%是非接触性前交叉韧带损伤，即球员与对手球员之间没有接触。根据受伤肢体足部最初接触地面的事件，发现了三种损伤机制:单腿铸造(平均背屈角度18.9°(14.4°));平均膝关节屈曲角度15.6°(7.8°);平均躯干外侧屈曲18.2°(8.4°);双侧跳(平均背屈角度18.2°(15.2°)，平均膝关节屈曲角度21°(14.5°)，平均躯干伸角6.9°(11.4°)，离运动员质心的落点角度47.9°(10.1°));接触后单腿落地(摆腿外展角平均105.4°(18.1°)，伤肢膝关节屈曲角平均34.2°(8.0°)，躯干同侧屈曲角平均22.2°(7.0°))。

期刊介绍： The mission of the Journal of Applied Biomechanics (JAB) is to disseminate the highest quality peer-reviewed studies that utilize biomechanical strategies to advance the study of human movement. Areas of interest include clinical biomechanics, gait and posture mechanics, musculoskeletal and neuromuscular biomechanics, sport mechanics, and biomechanical modeling. Studies of sport performance that explicitly generalize to broader activities, contribute substantially to fundamental understanding of human motion, or are in a sport that enjoys wide participation, are welcome. Also within the scope of JAB are studies using biomechanical strategies to investigate the structure, control, function, and state (health and disease) of animals.
