Rupture of the Anterior Cruciate Ligment (ACL) is a common knee injury. The purpose of this study was to determine the balance control in football players with and without ACL reconstruction in posture of injury.
Sway of the center of gravity of 15 patients with ACL reconstruction was compared with 15 healthy, age and sex-matched subjects as the control group. All tests were done unilaterally in the posture of injury, using a kistler force plate with the open and -closed eye conditions.
The knee of the operated side of the case group showed more displacement of the center of gravity when compared to the non-operated side in the same subject for all variables of the force plate. The operated side of the case group showed more displacement of the center of gravity for all variables of the force plate in comparison with the dominant side of knees in control group. There were significant differences between the non-operated side in the case group and the dominant side of the control group.
All together, postural control in the operated side of the case group was weaker than the nonoperated side of the same group and the dominant limb of the control group, which might have resulted from poor proprioception. The postural control was even weaker in the non-operated side of the case group as compared with the dominant limb of the control group, which can justify the hypo mobility of limb for several months after the surgery.
前交叉韧带（ACL）断裂是一种常见的膝关节损伤。本研究的目的是确定在损伤姿势下，进行和未进行ACL重建的足球运动员的平衡控制情况。
将15例进行了ACL重建的患者的重心摆动情况与15名年龄、性别匹配的健康受试者作为对照组进行比较。所有测试均在损伤姿势下单侧进行，使用奇石乐测力板，分别在睁眼和闭眼条件下进行。
对于测力板的所有变量，病例组手术侧膝关节的重心位移比同一受试者的非手术侧更大。病例组手术侧膝关节在测力板所有变量上的重心位移比对照组膝关节优势侧更大。病例组非手术侧与对照组优势侧之间存在显著差异。
总体而言，病例组手术侧的姿势控制比同组非手术侧以及对照组优势肢体更弱，这可能是本体感觉不佳所致。病例组非手术侧的姿势控制与对照组优势肢体相比甚至更弱，这可以解释手术后几个月肢体活动度降低的原因。
