Abstract：Objective: To analyze the correlation between quantitative parameters related to MRI and degenerative rotator cuff tear. Methods: From May 2021 to July 2021, 40 patients with degenerative rotator cuff tear diagnosed by MRI or shoulder arthroscopy in the Affiliated Hospital of Chengde Medical College were selected as the case group, and 40 healthy volunteers as the control group. Both groups were examined by MRI, and measured for the acromion–greater tuberosity impingement index (ATI), acromion index (AI) and glenoid inclination (GI). The statistical differences of the parameters of the two groups were analyzed, and the correlation analysis was carried out between the parameters. Results: The mean ATI, AI and GI was 0.87±0.04, 0.70±0.10, 13.11°±5.62°in the case group. And the mean ATI, AI and GI was 0.84±0.05, 0.65±0.07, 10.43°±4.92°in the control group. There were significant differences between the two groups (t = 2.264, 2.301, 2.179, P<0.05). And the correlation analysis showed that ATI was positively correlated with AI and GI, while AI and GI had a moderate positive correlation (r = 0.452, 0.283, 0.254, P<0.05). Conclusion: ATI, AI and GI measured with MRI can be used as good parameters for predicting degenerative rotator cuff tears.
