The purpose of this study was to assess the sagittal knee kinematics of rectus femoris transfer without hamstring lengthening. A retrospective review of seventeen children (29 knees) was performed. Gait analysis was performed prior to surgery and repeated at a minimum of one year after surgery. Sagittal knee kinematics were analyzed. Stance minimum knee flexion increased 7 degrees; swing maximum knee flexion increased 5 degrees; and swing minimum knee flexion increased 5 degrees. The present study confirmed previously reported increases in swing maximum knee flexion. Increases in stance minimum knee flexion and swing minimum knee flexion were also found. These findings have not been previously reported.
本研究的目的是评估在不进行腘绳肌延长的情况下股直肌转移术后膝关节矢状面的运动学变化。对17名儿童（29个膝关节）进行了回顾性研究。在手术前进行步态分析，并在术后至少一年重复进行。对膝关节矢状面的运动学进行了分析。站立期最小屈膝角度增加了7度；摆动期最大屈膝角度增加了5度；摆动期最小屈膝角度增加了5度。本研究证实了先前报道的摆动期最大屈膝角度增加的情况。还发现站立期最小屈膝角度和摆动期最小屈膝角度也有所增加。这些发现此前尚未见报道。
