Early Versus Delayed Postoperative Mobilization After Arthroscopic Rotator Cuff Tear Reapair.

Arthroscopic suture for complete and partial \>50% thickness Rotator Cuff Tears (RCT) is the gold standard. However, there is no evidence of superiority of delayed postoperative mobilization protocols versus early ones, in terms of ROM, pain, quality of life and complications in last review published in 2019 by AAOS. Although, excessive immobilization can lead into stiffness, neuropathic pain or adhesive capsulitis. All of these are complications which can diminish patient quality of life or prolong their return to work or sports activities. This is an experimental, prospective, non-blind, comparative, randomized clinical trial, between two options of treatment. On one treatment branch, investigators will continue applying the standard postoperative 4 weeks immobilization rehabilitation program with a sling in adduction and internal rotation. On the other treatment branch, investigators will start passive mobilization during second week after surgery, including controlled external rotation movements. All recruited patients will be followed-up during 12 months. Main objective is to compare differences in terms of functionality (using ASES scale). Secondary objectives are to compare differences in terms of ROM, functionality (using CMS and UCLA scales), pain (using VAS score), need of analgesic drugs, quality of life (using EQ-5D scale), return to previous work and sports activities, patient adhesion to protocol, complications and MRI rotator cuff retear ratio at 12 months follow-up. After this study, investigators hope to develop a new postoperative mobilization protocol for patients. This protocol will be focused on timing, and self-administrated exercises in order to involve patients in their recovery, in the fastest and safest way for them.
