The purpose was to quantify the effect of an anterior cruciate ligament (ACL) injury on balance and jump-landing performance and bilateral asymmetries. Among 500 collegiate athletes who performed a reaching test and a double-leg counter-movement jump-landing test at baseline, 8 male and 6 female athletes suffered ACL injuries. In the follow-up, they performed the reaching test 3 and 6 months after ACL reconstruction (ACLR) and the jump-landing test 6 months after ACLR. Less reaching distances for the injured leg and increased reaching distance asymmetries were observed 3 and 6 months after ACLR compared to baseline. Less peak jumping and landing forces for the injured leg and increased jumping and landing force asymmetries were found 6 months after ACLR compared to baseline. The decreased performance of the injured leg and increased asymmetries may contribute to the high ACL re-injury rates. Baseline assessments would be useful for establishing an individual's pre-injury performance.
目的是定量评估前交叉韧带(ACL)损伤对平衡和跳跃着陆表现以及双侧不对称性的影响。在 500 名进行过伸展测试和双腿反向跳跃着陆测试的大学生运动员中,有 8 名男性和 6 名女性运动员遭受 ACL 损伤。在随访中,他们在 ACL 重建(ACLR)后 3 个月和 6 个月进行伸展测试,在 ACLR 后 6 个月进行跳跃着陆测试。与基线相比,ACL 重建后 3 个月和 6 个月时,受伤腿的伸展距离较小,伸展距离的不对称性增加。与基线相比,ACL 重建后 6 个月时,受伤腿的最大跳跃和着陆力较小,跳跃和着陆力的不对称性增加。受伤腿的运动表现下降和不对称性增加可能导致 ACL 再损伤率较高。基线评估对于确定个体的受伤前表现非常有用。
