To analyse postural stability and the single-leg hop for distance in subjects 2 years after anterior cruciate ligament reconstruction (ACLR), in comparison with an age- and activity-matched control group.
Subjects reported to a sports medicine or athletic training research laboratory for testing.
Twenty-six subjects having undergone ACLR and 26 age- and activity-matched controls were selected to participate in this study. An arthroscopically-assisted, central, one-third bone-patellar tendon procedure was used to repair the ACLs.
One-leg stance postural stability was measured with the NeuroCom Balance Master platform system. We recorded the single-leg hop for distance as an objective measure of function.
We found a significant difference (p<0.05) between the ACLR and control subjects in terms of the one-leg stance sway velocity (knee fully extended) on the operated side.
After ACLR (mean time postoperatively: 24+/-1 months), single-leg hop for distance score was normal, when compared with the contralateral limb. Our results indicate that 2 years after surgery, single-limb postural stability in the ACLR group differed significantly from that in the control group. The persistence of poor stability control may be correlated to an impairment in proprioception.
与年龄及活动量相匹配的对照组相比，分析前交叉韧带重建术（ACLR）两年后受试者的姿势稳定性和单腿跳远距离情况。
受试者前往运动医学或运动训练研究实验室接受测试。
选取26例接受过ACLR的受试者以及26例年龄和活动量相匹配的对照者参与本研究。采用关节镜辅助下的中央三分之一髌腱手术修复前交叉韧带。
使用NeuroCom Balance Master平台系统测量单腿站立姿势稳定性。记录单腿跳远距离作为功能的客观测量指标。
在患侧单腿站立摇摆速度（膝关节完全伸展）方面，ACLR组与对照组之间存在显著差异（p<0.05）。
ACLR术后平均时间为24±1个月时，与对侧肢体相比，单腿跳远距离得分正常。我们的结果表明，术后两年，ACLR组的单肢姿势稳定性与对照组有显著差异。稳定性控制不佳的持续存在可能与本体感觉受损有关。
