Abstract

Purpose: To evaluate fatty degeneration and atrophy of rotator cuff muscle by investigate normal patients and patients received repair of rotator cuff surgeries. Materials and Methods: We chose 328 normal cases(male:160 cases, female:168 cases) and 41 cuff tear patients(male:17 cases, female:24 cases) who received rotator cuff repair surgeries. Normal patients were categorized according to age. In cuff tear group, we need to devided into 2 subgroups, the one was 30 cases(male:13cases, female:17cases) of group 1 that primary repair were enough and the other was 11cases(male:4cases, female:7cases) of group 2 that symptomatic rotator cuff retear occured. The radiologic parameters(Fatty degeneration, Atrophy) and clinical outcomes(VAS, UCLA, Constant, Oxford) were evaluated. Results: There were no differences in fatty degeneration and atrophy following aging process and the tear group revealed significant fatty degeneration and atrophy of rotator cuff muscle. In the group 2, there were significantly higher fatty degeneration on follow up MRI(P-0.024) and had more fatty degeneration and muscle atrophy than group 1 but there were no statistical significance. In clinical assessment, more satisfactory result were obtained in the group 1 but there were no statistical significance. Conclusion: Fatty degeneration and atrophy of the rotator cuff was free from normal aging process but fatty degeneration process would be accelerated followed by cuff tear injuries even through repair of rotator cuff. And preoperative fatty degeneration more than 3 grade have more higher retear rate of rotator cuff
