膝关节置换植入物的设计具有在屈曲范围内提供不同关节约束的特征，使得膝关节运动的模式也可以改变。由于全膝关节植入物的运动直接影响患者的功能和设备寿命，因此了解基于各种设计理念的膝关节植入物在体内的表现是很重要的。对5种植入物的59个膝关节在步态和爬楼梯活动过程中的透视成像进行了研究。许多膝关节在步态和楼梯活动之间表现出显著不同的运动学，以及与其他植入设计的膝盖的不同。测量的运动与种植体部件提供的内在约束以及约束在屈曲范围内的变化一致。关键词：膝关节成形术、运动学、透视、假体设计、步态、爬楼梯。(C)2004 Elsevier Inc.保留所有权利。
Knee arthroplasty implants are designed with features that provide varying articular constraint over the range of flexion such that the pattern of knee motion may also vary. Because the motions of total knee implants have a direct influence on patient function and device longevity, it is important to understand how knee implants based on a variety of design philosophies perform in vivo. Fifty-nine knees in patients with 5 designs of implants were studied with fluoro-scopic imaging during gait and stair-climbing activities. Many knees showed significantly different kinematics between the gait and stair activities, as well as differences from knees having other implant designs. The measured motions were consistent with the intrinsic constraint provided by the implant components and the variation in constraint over the flexion range. Key Avords: knee arthroplasty, kinematics, fluoroscopy, implant design, gait, stair climbing. (C) 2004 Elsevier Inc. All rights reserved.
