Abstract
BACKGROUND: Rotator cuff tears are closely related with muscle atrophy and fatty infiltration and both affect healing after surgical treatment. The aim of this study was to compare surgical versus conservative management of medium-to-large reparable rotator cuff tears. METHODS: Forty-one patients with clinical and radiological (MRI) diagnosis of medium-to-large rotator cuff tears were retrospectively identified and divided into two groups: Group A, arthroscopic repair; Group B, conservative treatment. At follow-up (T1) all patients underwent a new clinical (VAS, SST, Constant and Relative Constant Scale) and radiological evaluation (MRI). RESULTS: When comparing the two groups at T1 (mean follow-up: Group A, 50 months; Group B, 61 months), we registered better results in Group A in the SST (p < 0.05), the VAS score (p < 0.01), the Constant and the Relative Constant Scale (p < 0.05). Radiological evaluation did not show a significant increase of fatty infiltration (p = 0.16) in Group A (no progression in 15 out of 17 patients -82.3%-, and an increase in 2 out of 17 patients -11.7%-), while in Group B a significant increase was detected (p < 0.01) in all patients; in regard to muscle atrophy, no cases of progression were detected in Group A (4 out of 17 patients -23.5%- showed an increased post-operative supraspinatus trophysm), while a significant worsening (p < 0.05) was found in Group B. In Group B a significant worsening of tendon retraction (p < 0.01) and of tear size (p = 0.01) was also detected. CONCLUSIONS: Surgical treatment of complete rotator cuff tears seems to decrease the irreversible changes that involve muscle belly.
