本研究的目的是动态评估使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，并确定其动态膝关节功能是否与股四头肌和腘绳肌肌力相关。采用计算机运动分析和测力板系统，测定了22例前交叉韧带重建受试者（平均年龄27 ± 11岁）和22例年龄和性别匹配的健康对照受试者在各种动态活动期间的膝关节运动学和动力学。在轻度（步行）、中度（爬楼梯和下楼梯）和高要求（慢跑、慢跑和切割、慢跑和停止）活动期间，两组之间矢状面角度和外部力矩的差异与等速力量测量相关。尽管前交叉韧带重建后无症状且功能良好的患者可以在轻度活动中正常活动，但高需求活动显示出持续的功能适应，需要进一步研究。
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.
