Values are presented as mean ± standard deviation.

RCT: rotator cuff tear, LAA: lateral acromial angle, CSA: critical should der angle, AP: anteroposterior, AT: acromial tilt, APCI: anteroposterior coverage index, AHI: acromiohumeral interval.

*Statistically significant. According to the classification by Beeler et al.5)
