To evaluate the healing of supraspinatus tendon lesions after arthroscopic repair, with analysis of intra- and inter-observer agreement by two experienced evaluators for the same lesions.
A study was conducted with patients evaluated in the postoperative period of arthroscopic surgery to repair isolated supraspinatus tendon ruptures, with a minimum follow-up of one year. Tendon healing was evaluated using magnetic resonance imaging by two independent evaluators at two time points, with a seven-day interval between them. Categorical data were presented in absolute and relative frequencies, and mixed linear regression models were used to analyze intra- and inter-observer agreement, with a probability of rejecting the null hypothesis of 5%.
Twenty-three patients (26 shoulders) were evaluated, with a mean age of 61.5 years. At both evaluation times, most patients presented a healing grade between I and III in the Sugaya classification for both observers. The interobserver agreement was good, and the intraobserver agreement was excellent.
The mean tendon healing rate for arthroscopic repair of isolated supraspinatus ruptures was 81.7%. Intra-observer agreement ratings were considered excellent, while inter-observer agreement was good, demonstrating reliability in the evaluations performed.
评估关节镜修复术后冈上肌腱损伤的愈合情况，并分析两名经验丰富的评估者对同一损伤的观察者内及观察者间的一致性。
对关节镜手术修复孤立性冈上肌腱断裂术后患者进行研究，随访至少一年。两名独立评估者在两个时间点使用磁共振成像评估肌腱愈合情况，时间间隔为7天。分类数据以绝对和相对频率呈现，采用混合线性回归模型分析观察者内及观察者间的一致性，拒绝零假设的概率为5%。
评估了23例患者（26个肩部），平均年龄61.5岁。在两个评估时间点，两位观察者对大多数患者的Sugaya分类愈合等级均在I至III级之间。观察者间一致性良好，观察者内一致性优秀。
孤立性冈上肌腱断裂关节镜修复的平均肌腱愈合率为81.7%。观察者内一致性评级为优秀，观察者间一致性良好，表明所进行评估具有可靠性。
