概要	BACKGROUND:The aim of this study was to identify, during total knee arthroplasty surgery, the effect on patellar kinematics of different patellar component designs in the same patients.METHODS:This study enrolled 84 patients with osteoarthritis. Intraoperative X-rays were used to measure internal rotation angle, flexion angle and lateral tilt were at different knee flexion angles with dome-type or anatomic-type patellar components (ATTUNE®, DePuy).RESULTS:Significant differences from baseline between the two types of components occurred at 120° of the knee flexion in the internal rotation angle, at 90° and 120° of the knee flexion in the flexion angle, and at 60° of the knee flexion in the lateral tilt.CONCLUSION:This study revealed that the difference in patellar component design affects patellar kinematics. Therefore, the difference in patellar component design may affect patellar stability.
