The Sugaya classification based on magnetic resonance imaging (MRI) is widely used to analyze the integrity of the rotator cuff tendon after surgery.This system classifies repaired rotator cuff tendons into 5 categories based on tendon signal intensity, thickness, and remaining defects, rather than simply as retorn and healed. 1)It is accepted as a reliable and reproducible method by several studies evaluating inter-and intraobserver reliability tests. 2)The postoperative rotator cuff integrity based on this classification was found to be correlated with clinical outcomes
Jeong et al. (Thu,) studied this question.
