这项研究的目的是描述一组根据功能能力分组的前交叉韧带缺陷受试者之间的运动学和运动学差异。对16例前交叉韧带完全性断裂患者进行研究，其中8例患者有日常生活活动不稳定(非COPES)，8例患者已恢复伤前无限制活动(COPES)。采集了行走、慢跑和上行一步过程中膝关节和踝关节的三维运动学和动力学数据。结果显示，两组人都减轻了接触地板的力量，但不戴铜板的人受累肢体的膝关节屈曲程度一直较低。研究人员使用的关节运动学与他们未受损伤的膝盖的关节运动学相似，也类似于未受伤受试者的膝关节运动。无铜者受累膝关节活动度降低与股四头肌无力无直接关系。数据表明，非铜者采用稳定膝关节的策略，使膝关节僵硬，这不仅不成功，而且可能导致过多的关节接触力，有可能损害关节结构。Cops采用了一种策略，允许正常的膝关节运动学，并预示着关节的完整性。(C)1998爱思唯尔科学有限公司。保留所有权利。
The purpose of this study was to describe kinematic and kinetic differences between a group of ACL deficient subjects who were grouped according to functional ability. Sixteen patients with complete ACL rupture were studied; eight subjects had instability with activities of daily living (non-copers) and eight subjects had returned to all pre-injury activity without limitation (copers). Three-dimensional joint kinematics and kinetics were collected from the knee and ankle during walking, jogging and going up and over a step. Results showed that both groups mitigated the force with which they contacted the floor but non-copers consistently demonstrated less knee flexion in the involved limb. The copers used joint kinematics similar to those of their uninvolved knees and similar to knee motions reported in uninjured subjects. The reduced knee motion in the involved knee of the non-copers did not correlate directly with quadriceps femoris muscle weakness.The data suggest that the non-copers utilize a stabilization strategy which stiffens the knee joint which not only is unsuccessful but may lead to excessive joint contact forces which have the potential to damage articular structures. The copers use a strategy which permits normal knee kinematics and bodes well for joint integrity. (C) 1998 Elsevier Science Ltd. All rights reserved.
