The in vivo kinematics of two types of unconstrained, posterior cruciate ligament retaining knee prostheses were analyzed 1 year postoperatively using roentgen stereophotogrammetric analysis. Ten knees had the Miller-Galante and five the New Jersey LCS design. The Miller-Galante knees displayed decreased adduction during active flexion when compared with normal knees. In both types of prostheses, there was decreased medial and increased proximal and posterior displacement. The abnormal kinematics probably reflect the design of the articular surfaces, the absence of the anterior cruciate ligament, and the dysfunction of the posterior cruciate ligament.
使用X线立体摄影测量分析法，在术后1年对两种非限制性、保留后交叉韧带的膝关节假体的体内运动学进行了分析。10例膝关节采用Miller-Galante假体，5例采用新泽西LCS设计。与正常膝关节相比，Miller-Galante膝关节在主动屈曲时内收减少。在两种类型的假体中，内侧位移均减少，近端和后方位移增加。异常的运动学可能反映了关节面的设计、前交叉韧带的缺失以及后交叉韧带的功能障碍。
