The purpose of this study was to dynamically assess the functional outcome of patients who had undergone successful anterior cruciate ligament reconstruction using an autologous patellar tendon technique and to determine whether their dynamic knee function was related to quadriceps and hamstring muscle strength. The knee kinematics and kinetics of 22 subjects who had undergone anterior cruciate ligament reconstruction (mean age, 27 +/- 11 years) and of 22 age- and sex-matched healthy control subjects were determined during various dynamic activities using a computerized motion analysis and force plate system. The differences in the sagittal plane angles and external moments between the two groups during light (walking), moderate (climbing and descending stairs), and higher-demand (jogging, jog and cut, jog and stop) activities were related to isokinetic strength measurements. Although patients who are asymptomatic and functioning well after anterior cruciate ligament reconstruction can perform normally in light activities, higher-demand activities reveal persistent functional adaptations that require further study.
本研究的目的是动态评估采用自体髌腱技术成功进行前交叉韧带重建的患者的功能结局,并确定其膝关节动态功能是否与股四头肌和腘绳肌力量相关。使用计算机化运动分析和测力板系统,测定了22例接受前交叉韧带重建的受试者(平均年龄27±11岁)以及22例年龄和性别匹配的健康对照受试者在各种动态活动中的膝关节运动学和动力学。两组在轻度(步行)、中度(上下楼梯)和高需求(慢跑、急停急转、慢跑并停止)活动期间矢状面角度和外力矩的差异与等速肌力测量结果相关。尽管前交叉韧带重建后无症状且功能良好的患者在轻度活动中可以正常表现,但高需求活动显示出持续的功能适应性,需要进一步研究。
