Functional treatment in rotator cuff tears: is it safe and effective? A retrospective comparison with surgical treatment.

Background: The aim of this study was to compare rehabilitation protocol and operative treatment in a population of patients with a diagnosis of small to medium rotator cuff tears (≤3 cm), the null hypothesis being that there would been no difference in terms of clinical outcomes and patient's satisfaction between the rehabilitation protocol and the surgical treatment.

Methods: Patients with small to medium supraspinatus tears were retrospectively enrolled in this study and divided in 2 groups: arthroscopic repair (group A, 20 patients) and reinstated (group B, 18 patients). At a mean follow-up of 18 months, both groups underwent clinical (Constant, QuickDash, VAS), dynamometric and ultrasonographic evaluation.

Results: In both groups a significant clinical improvement was registered compared to baseline. However, surgical treatment yielded better results in Constant (p=0.004), Quick-Dash (p=0.0012), VAS (p=0.048) and strength evaluation (p=0.0014). In group A the re-tear rate was 10%, while in group B only 11% of increased tear size was registered.

Conclusion: At a short term follow-up, the surgical treatment of small to medium supraspinatus tears yielded better clinical outcomes compared to the rehabilitation protocol, with better strength outcomes and 10% re-tear rate. Nevertheless, physiotherapy still offers acceptable results and could be a valuable option in patients not undergoing surgery.

Level Of Evidence: III.
