In the field of orthopedics, it is important to analyze the kinematics of the shoulder joints. In this research group, kinetic analysis of the shoulder joints with high accuracy was made possible using our original image matching method. The aim of this study was to reproduce the relative relationship of bones on 3D-CAD based on 6 degrees of freedom, and analyze the relative relationship between the humeral head and the glenoid cavity. The dynamic glenohumeral kinematics during full axial rotation was analyzed in two rotator cuff tear (RCT) patients before and after arthroscopic rotator cuff repair (ARCR). After kinetic analysis calculates 6 degrees of freedom, the relationship between the scapula and the humerus was reproduced using 3D-CAD, and the distance between the humeral head and the glenoid cavity was estimated. The difference between RCT shoulder and ARCR shoulder during full axial rotation was confirmed. This finding is clinically important as it may provide valuable information as one of the quantitative assessments of RCT shoulders.
