This study evaluate if in an outpatient rotator cuff surgery, can the use of mobile app compared to conventional paper questionnaire improve follow-up care in the first 90-days following surgery.

Rotator cuff surgery is a painful arthroscopic surgery. In outpatient surgery, the surgeons have to increase the security and surveillance after the surgery to reassure the patient and avoid complications.

Most patients receiving ambulatory rotator cuff surgery have high pain score, and management and aspects of the rehabilitation can be challenging. However, regular follow-up is still considered important in the early post-operative phase. In between the conventional appointment 6 weeks post op and 12 weeks post op, the surgeons have no status of the patient, and no markers to check if the postoperative care is evolving right.

Currently, the investigators are using a mobile application (Orthense by Digikare, Blagnac, France) to complement in-person postoperative follow-up care for patients.

Inclusion Criteria:

• Patients undergoing rotator cuff surgery. They must be able to use a mobile-app, and have an email address and internet connexion.

Exclusion Criteria:

• Unable to read French
