Agility running activities are commonly used in the latter stages of rehabilitation for anterior cruciate ligament (ACL) reconstruction. However, the effects of agility running on anterior knee laxity in these patients have not been examined. The purpose of this study was to examine changes in anterior knee laxity before and after 30 minutes of agility running exercise. Subjects (N = 9) were female athletes (mean age = 20.1 +/- 1.5 years; height = 171.7 +/- 10.4 cm; weight = 65.7 +/- 8.6 kg) with unilateral ACL reconstruction (central 1/3 patella tendon graft, postoperation range = 9-52 months, mean = 24.2 months). Measurements were made at 20 degrees and 90 degrees of knee flexion bilaterally with KT-1000 arthrometry (MEDmetric, San Diego, CA) and recorded in millimeters of displacement. Data were analyzed with an analysis of variance (ANOVA) with repeated measures (p < 0.05). Results showed no statistical differences between the ACL-reconstructed knee and the normal knee at 20 degrees and 90 degrees knee flexion. The authors conclude that the central 1/3 patella tendon graft performs comparable to the normal knee when stressed with agility running exercise; therefore, agility exercise is an appropriate, safe, short-term activity.
敏捷跑活动常用于前交叉韧带（ACL）重建康复的后期阶段。然而，敏捷跑对这些患者膝关节前侧松弛度的影响尚未得到研究。本研究的目的是检测30分钟敏捷跑运动前后膝关节前侧松弛度的变化。受试者（N = 9）为单侧ACL重建的女性运动员（平均年龄 = 20.1 ± 1.5岁；身高 = 171.7 ± 10.4厘米；体重 = 65.7 ± 8.6千克）（采用中央1/3髌腱移植，术后时间范围 = 9 - 52个月，平均 = 24.2个月）。使用KT - 1000关节测量仪（MEDmetric，加利福尼亚州圣地亚哥）在双侧膝关节屈曲20度和90度时进行测量，并记录位移的毫米数。采用重复测量方差分析（p < 0.05）对数据进行分析。结果显示，在膝关节屈曲20度和90度时，ACL重建侧膝关节与正常膝关节之间无统计学差异。作者得出结论，在进行敏捷跑运动时，中央1/3髌腱移植的表现与正常膝关节相当；因此，敏捷运动是一种合适、安全的短期活动。
